Information packet provided by finnish doctor Rauni Kilde

I just have to post something about this great person called Rauni Kilde here from Finland. She has much information about paranormal, aliens, ufology, mind control etc.

Rauni-Leena Luukanen-Kilde in 2012.

Rauni-Leena Luukanen-Kilde (born Värtsilä, 15 November 1939) is a Finnish physician who has been an author and lecturer on parapsychology, ufology and mind control since 1982. She now lives in Norway.

Luukanen-Kilde had to flee with her family in infancy during the Second World War and was raised in Helsinki.[1] She studied medicine at the universities of Oulu and Turku, graduating in 1967. She was at one point the only medical practitioner at the hospital in Pelkosenniemi, performing dental and veterinary work as well.[2] In March 1975, she became a provincial medical officer in Rovaniemi, Lapland;[1] she became chief medical officer for Lapland.[2][3]

In 1982, as Rauni-Leena Luukonen, she published Kuolemaa ei ole (There Is No Death).[4] She has been interested in the paranormal since she was a teenager, but her interest in UFOs may date to a 1985 car accident which led to her retirement. She has since been a featured speaker at UFO conferences, helped organize the first international conference on extraterrestrials in Finland[5] and authored books about UFOs, alien abductions, mind control and conspiracy theories. Luukanen-Kilde has claimed to have been “rescued” from danger by extraterrestrials, and to have esoteric skills and knowledge as a result of her relationship with them. She maintains that there is a secret exchange program between humans and aliens that is being deliberately suppressed by “powerful Western governments”, particularly the United States.[1] Luukanen-Kilde also claims there are secret military and intelligence agencies practising mind control technology on the world population using cell phones and supercomputers and that a plot to kill most of the Earth’s population using the swine flu vaccine is being carried out by the WHO, Henry Kissinger, and the Bilderberg Group.[6] Her article on cybernetic implants as a means of control is widely circulated.[7] She appears in the 1999 film Revelations: The End Times, Volume 2.

Luukonen-Kilde has lived in Norway since 1992;[8] she married a Norwegian diplomat in 1987.[1]

Silenced people, Robin Cook (murdered)

Was a British Labour Party politician Robin Cook a victim of NWO?

Robin Cook

In office
8 June 2001 – 17 March 2003

Robert Finlayson “Robin” Cook (28 February 1946 – 6 August 2005) was a British Labour Partypolitician, who was the Member of Parliament (MP) for Livingston from 1983 until his death, and served in the Cabinet as Foreign Secretary from 1997 to 2001.

He studied at the University of Edinburgh before becoming a Member of Parliament for Edinburgh Central in 1974. In parliament he was noted for his debating ability which saw his rise through the political ranks and ultimately to the Cabinet.

He resigned from his positions as Lord President of the Council and Leader of the House of Commons on 17 March 2003 in protest against the invasion of Iraq. At the time of his death, he was President of the Foreign Policy Centre and a vice-president of the America All Party Parliamentary Group and the Global Security and Non-Proliferation All Party Parliamentary Group.

Early life

Robin Cook was born in the County Hospital, Bellshill, Scotland, the only son of Peter and Christina Cook (née Lynch). His father was a chemistry teacher who grew up in Fraserburgh, and his grandfather was a miner before being blacklisted for being involved in a strike.

Cook was educated at Aberdeen Grammar School and, from 1960, the Royal High School in Edinburgh. At first, Cook intended to become a Church of Scotland minister, but lost his faith as he discovered politics. He joined the Labour Party in 1965 and became an atheist. He remained so for the rest of his life. He then studied English Literature at the University of Edinburgh, where he obtained an MA with Honours in English Literature. He began studying for a PhD on Charles Dickens and Victorian serial novels, supervised by John Sutherland, but gave it up in 1970.

In 1971, after a period working as a secondary school teacher, Cook became a tutor-organiser of the Workers’ Educational Association for Lothian, and a local councillor in Edinburgh. He gave both up when elected a member of parliament on his 28th birthday, in February 1974.

Personal life

Cook also worked as a racing tipster in his spare time. He was introduced to horse racing by his wife, Margaret Katherine Whitmore, from Somerset, whom he met whilst at Edinburgh University. They married on 15 September 1969 at St Alban’s Church, Westbury Park, Bristol and had two sons, Peter and Christopher, born in February 1973 and May 1974. Between 1991 and 1998 Cook wrote a weekly tipster’s column for the Glasgow Herald newspaper.

Shortly after he became Foreign Secretary, Cook ended his marriage with Margaret, revealing that he had an extra-marital affair with one of his staff, Gaynor Regan.[1] He announced his intentions to leave his wife and marry another woman via a press statement made at Heathrow on 2 August 1997. Cook was forced into a decision over his private life after a telephone conversation with Alastair Campbell as he was about to go on holiday with his first wife. Campbell explained that the press was about to break the story of his affair with Regan. His estranged wife subsequently accused him of being insensitive during their marriage, of having had several extramarital affairs and alleged he was an alcoholic.

Robin married Regan in Tunbridge Wells, Kent[2] on 9 April 1998, four weeks after his divorce was finalised.

Early years in Parliament

Cook unsuccessfully contested the Edinburgh North constituency in the 1970 general election, but was elected to the House of Commons at the February 1974 general election as Member of Parliament for Edinburgh Central, defeating George Foulkes for nomination. When the constituency boundaries were revised for the 1983 general election, he transferred to the new Livingston constituency, beating Tony Benn to the selection, which he represented until his death.

In parliament, he joined the left-wingTribune Group of the Parliamentary Labour Party and frequently opposed the policies of the Wilson and Callaghan governments. He was an early supporter of constitutional and electoral reform (although he opposed devolution in the 1979 referendum, eventually coming out in favour on election night in 1983), and of efforts to gain more women MPs. He also supported unilateral nuclear disarmament and the abandoning of the Labour Party’s euroscepticism of the 1970s and 1980s. During his early years in parliament Cook championed several liberalising social measures, to mixed effect. He repeatedly (and unsuccessfully) introduced a private member’s bill on divorce reform in Scotland, but succeeded in July 1980 — and after three years’ trying—with an amendment to bring the Scottish law on homosexuality into line with that in England.

After Labour lost power in May 1979 Cook encouraged Michael Foot‘s bid to become party leader and joined his campaign committee. When Tony Benn challenged Denis Healey for the party’s deputy leadership in September 1981, Cook supported Healey.

In opposition

He became known as a brilliant parliamentary debater, and rose through the party ranks, becoming a frontbench spokesman in 1980, and reaching the Shadow Cabinet in 1987, as Shadow Social Services Secretary. He was campaign manager for Neil Kinnock‘s successful 1983 bid to become leader of the Labour Party, and was one of the key figures in the modernisation of the Labour Party under Kinnock. He was Shadow Health Secretary (1987–92) and Shadow Trade Secretary (1992–94), before taking on foreign affairs in 1994, the post he would become most identified with (Shadow Foreign Secretary 1994-97, Foreign Secretary 1997-2001).

In 1994, following the death of John Smith, he ruled himself out of contention for the Labour leadership, apparently on the grounds that he was “insufficiently attractive” to be an election winner, although two close family bereavements in the week in which the decision had to be made may have contributed.

Despite his role in modernising the party under Kinnock and Smith, Cook was said to be never fully committed to Blair’s “New Labour” project, considering it a step too far to the right.

On 26 February 1996, following the publication of the Scott Report into the ‘Arms-to-Iraq‘ affair, he made a famous speech in response to the then President of the Board of Trade Ian Lang in which he said “this is not just a Government which does not know how to accept blame; it is a Government which knows no shame”. His parliamentary performance on the occasion of the publication of the five-volume, 2,000-page Scott Report — which he claimed he was given just two hours to read before the relevant debate, thus giving him three seconds to read every page — was widely praised on both sides of the House as one of the best performances the Commons had seen in years, and one of Cook’s finest hours. The government won the vote by a majority of one.

As Joint Chairman (alongside Liberal Democrat MP Robert Maclennan) of the Labour-Liberal Democrat Joint Consultative Committee on Constitutional Reform, Cook brokered the ‘Cook-Maclennan Agreement’ that laid the basis for the fundamental reshaping of the British constitution outlined in Labour’s 1997 General Election manifesto. This led to legislation for major reforms including Scottish and Welsh devolution, the Human Rights Act and removing the majority of hereditary peers from the House of Lords. Others have remained elusive so far, such as a referendum on the electoral system and further House of Lords reform. However, in 2011 voters in the United Kingdom were finally given the chance to have their say on replacing the first-past-the-post voting system with the Alternative Vote method in a referendum held on 5 May. On 6 May it was announced that any proposed move to the AV voting system had been rejected by the minority of the electorate who voted by a margin of 67.9% to 32.1%.

In government

Foreign Secretary

With the election of a Labour government at the 1997 general election, Cook became Foreign Secretary. He was believed to have coveted the job of Chancellor of the Exchequer, but that job was reportedly promised by Tony Blair to Gordon Brown. He announced, to much scepticism, his intention to add “an ethical dimension” to foreign policy.

His term as Foreign Secretary was marked by British interventions in Kosovo and Sierra Leone. Both of these were controversial, the former because it was not sanctioned by the UN Security Council, and the latter because of allegations that the British company Sandline International had supplied arms to supporters of the deposed president in contravention of a United Nations embargo. Cook was also embarrassed when his apparent offer to mediate in the dispute between India and Pakistan over Kashmir was rebuffed. The ethical dimension of his policies was subject to inevitable scrutiny, leading to criticism at times.

He is credited with having helped resolve the eight-year impasse over the Pan Am Flight 103 bombing trial by getting Libya to agree to hand over the two accused (Megrahi and Fhimah) in 1999, for trial in the neutral venue of the Netherlands but according to Scots law.

In March 1998, a diplomatic rift ensued with Israel when Israeli Prime Minister Benjamin Netanyahu angrily cancelled a dinner with Cook, while Cook was visiting Israel and had demonstrated opposition to the expansion of Israeli settlements.[3]

Leader of the House of Commons

After the 2001 general election he was moved, against his wishes, from the Foreign Office to be Leader of the House of Commons. This was widely seen as a demotion — although it is a Cabinet post, it is substantially less prestigious than the Foreign Office — and Cook nearly turned it down. In the event he accepted, and looking on the bright side welcomed the chance to spend more time on his favourite stage. According to The Observer,[4] it was Blair’s fears over political battles within the Cabinet over Europe, and especially the euro, which saw him unexpectedly demote the pro-European Cook.

As Leader of the House he was responsible for reforming the hours and practices of the Commons and for leading the debate on reform of the House of Lords. He also spoke for the Government during the controversy surrounding the membership of Commons Select Committees which arose in 2001, where Government whips were accused of pushing aside the outspoken committee chairs Gwyneth Dunwoody and Donald Anderson. He was President of the Party of European Socialists from May 2001 to April 2004.

In early 2003, during a live television appearance on BBC current affairs show Question Time, he was inadvertently referred to as “Robin Cock” by David Dimbleby. Cook responded with attempted good humour with “Yes, David Bumblebee”, and Dimbleby apologised twice on air for his slip. The episode also saw Cook in the uncomfortable position of defending the Government’s stance over the impending invasion of Iraq, weeks before his resignation over the issue.

He documented his time as Leader of the House of Commons in a widely acclaimed book ‘The Point of Departure’, which discussed in diary form his efforts to reform the House of Lords and to persuade his ministerial colleagues, including Tony Blair, to distance the Labour Government from the foreign policy of the Bush administration. The former Political Editor of Channel 4 News, Elinor Goodman called the book ‘the best insight yet into the workings of the Blair cabinet’, whilst the former Editor of The Observer, Will Hutton, called it ‘the political book of the year – a lucid and compelling insider’s account of the two years that define the Blair Prime Ministership’.

Resignation over Iraq war

In early 2003 he was reported to be one of the cabinet’s chief opponents of military action against Iraq, and on 17 March he resigned from the Cabinet. In a statement giving his reasons for resigning he said, “I can’t accept collective responsibility for the decision to commit Britain now to military action in Iraq without international agreement or domestic support.” He also praised Blair’s “heroic efforts” in pushing for the so-called second resolution regarding the Iraq disarmament crisis, but lamented “The reality is that Britain is being asked to embark on a war without agreement in any of the international bodies of which we are a leading partner—not NATO, not the European Union and, now, not the Security Council”. Cook’s resignation speech in the House of Commons, received with an unprecedented standing ovation by fellow MPs, was described by the BBC‘s Andrew Marr as “without doubt one of the most effective, brilliant, resignation speeches in modern British politics.”[5] Most unusually for the British parliament, Cook’s speech was met with growing applause from all sides of the House (beginning with Labour and Liberal Democrat critics of the war), and from the public gallery. According to The Economists obituary, that was the first speech ever to receive a standing ovation in the history of the House.[6]

Outside the government

After his 2003 resignation from the Cabinet, Cook remained an active backbench Member of Parliament until his death. After leaving the Government, Cook was a leading analyst of the decision to go to war in Iraq, giving evidence to the Foreign Affairs Select Committee which was later relevant during the Hutton and Butler inquiries. He was sceptical of the proposals contained in the Government’s Higher Education Bill, and abstained on its Second Reading.[7] He also took strong positions in favour of both the proposed European Constitution,[8] and a majority-elected House of Lords,[9][10] about which he said (whilst Leader of the Commons), “I do not see how [the House of Lords] can be a democratic second Chamber if it is also an election-free zone”.

In the years after his exit from the Foreign Office, and particularly since his resignation from the Cabinet, Cook made up with Gordon Brown after decades of personal animosity[11] — an unlikely reconciliation after a mediation attempt by Frank Dobson in the early 1990s had seen Dobson conclude (to John Smith) “You’re right. They hate each other.” Cook and Brown focused on their common political ground, discussing how to firmly entrench progressive politics after the exit of Tony Blair.[12]Chris Smith said in 2005 that in recent years Cook had been setting out a vision of “libertarian, democratic socialism that was beginning to break the sometimes sterile boundaries of ‘old’ and ‘New’ Labour labels.”.[13] With Blair’s popularity waning, Cook campaigned vigorously in the run-up to the 2005 general election to persuade Labour doubters to remain with the party.

In a column for the Guardian four weeks before his death, Cook caused a stir when he described Al-Qaeda as a product of a western intelligence:

Bin Laden was, though, a product of a monumental miscalculation by Western security agencies. Throughout the 80s he was armed by the CIA and funded by the Saudis to wage jihad against the Russian occupation of Afghanistan. Al-Qaida, literally “the database”, was originally the computer file of the thousands of mujahideen who were recruited and trained with help from the CIA to defeat the Russians.[14]

Death

Some commentators and senior politicians said that Cook seemed destined for a senior Cabinet post under a Brown premiership.[15]

In early August 2005, Cook and his wife, Gaynor, took a two-week holiday in the Highlands of Scotland. At around 2:20 pm, on 6 August 2005, whilst walking down Ben Stack in Sutherland, Scotland, Cook suddenly suffered a severe heart attack, collapsed, lost consciousness and fell about 8 ft down a ridge.[16] A helicopter containing paramedics arrived 30 minutes after a 999 call was made. Cook then was flown to Raigmore Hospital, Inverness. Gaynor did not get in the helicopter, and was left to walk down the mountain. Despite efforts made by the medical team to revive Cook in the helicopter, he was already beyond recovery, and at 4:05pm, minutes after arrival at the hospital, was pronounced dead. Two days later, a post mortem revealed that Cook died of hypertensive heart disease.

A funeral service was held on 12 August 2005, at St Giles Cathedral in Edinburgh, even though Cook had been an atheist.[17]Gordon Brown gave the eulogy, and German foreign minister Joschka Fischer was one of the guests. British Prime Minister Tony Blair, who was on holiday at the time, did not attend. In his speech at the funeral, Cook’s friend, the racing pundit John McCririck, criticised Blair for not attending.

A later memorial service at St Margaret’s Church, Westminster, on 5 December 2005, included a reading by Tony Blair and warm tributes by Gordon Brown and Madeleine Albright. On 29 September 2005, Cook’s friend and election agent since 1983, Jim Devine, won the resulting by-election with a reduced majority.

In January 2007, a headstone was erected in The Grange, Edinburgh Cemetery, where Cook is buried, bearing the epitaph: “I may not have succeeded in halting the war, but I did secure the right of parliament to decide on war.” It is a reference to Cook’s strong opposition to the 2003 invasion of Iraq and the words were reportedly chosen by his widow and two sons from his previous marriage, Chris and Peter.[18]

Nassim Haramein – The Pyramids & Orion Belt

I just love this guy and I have to post this update to Pyramid saga, because it’s just great.

Explore Orion’s Belt and the pyramids with physicist Nassim Haramein!

Nassim Haramein was born in Geneva, Switzerland in 1962. As early as 9 years old, Nassim was already developing the basis for a unified hyperdimensional theory of matter and energy, which he eventually called the ‘Holofractographic Universe.’

Haramein has spent most of his life researching the fundamental geometry of hyperspace, studying a variety of fields from theoretical physics, cosmology, quantum mechanics, biology and chemistry to anthropology and ancient civilizations. Combining this knowledge with a keen observation of the behavior of nature, he discovered a specific geometric array that he found to be fundamental to creation and from which the foundation for his Unified Field Theory emerged.

Motor of the past is the motor of the future

It looks like, that the future of motors is going to be so called Stirling engine, which is ecological and it produces free energy. Here I post you some history of it and then how to make your own motor at home.

Stirling engine

From Wikipedia, the free encyclopedia

A Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.[1][2] Or more specifically, a closed-cycle regenerative heat engine with a permanently gaseous working fluid, where closed-cycle is defined as a thermodynamic system in which the working fluid is permanently contained within the system, and regenerative describes the use of a specific type of internal heat exchanger and thermal store, known as the regenerator. It is the inclusion of a regenerator that differentiates the Stirling engine from other closed cycle hot air engines.

Originally conceived in 1816 as an industrial prime mover to rival the steam engine, its practical use was largely confined to low-power domestic applications for over a century.[3]

The Stirling engine is noted for its high efficiency compared to steam engines,[4] quiet operation, and the ease with which it can use almost any heat source. This compatibility with alternative and renewable energy sources has become increasingly significant as the price of conventional fuels rises, and also in light of concerns such as peak oil and climate change. This engine is currently exciting interest as the core component of micro combined heat and power (CHP) units, in which it is more efficient and safer than a comparable steam engine.[5][6]

Name and classification

Robert Stirling was the Scottish inventor of the first practical example of a closed cycle air engine in 1816, and it was suggested by Fleeming Jenkin as early as 1884 that all such engines should therefore generically be called Stirling engines. This naming proposal found little favour, and the various types on the market continued to be known by the name of their individual designers or manufacturers, e.g. Rider’s, Robinson’s, or Heinrici’s (hot) air engine. In the 1940s, the Philips company was seeking a suitable name for its own version of the ‘air engine’, which by that time had been tested with working fluids other than air, and decided upon ‘Stirling engine’ in April 1945.[7] However, nearly thirty years later Graham Walker still had cause to bemoan the fact such terms as ‘hot air engine’ continued to be used interchangeably with ‘Stirling engine’, which itself was applied widely and indiscriminately.[8]

Like the steam engine, the Stirling engine is traditionally classified as an external combustion engine, as all heat transfers to and from the working fluid take place through a solid boundary (heat exchanger) thus isolating the combustion process and any contaminants it may produce from the working parts of the engine. This contrasts with an internal combustion engine where heat input is by combustion of a fuel within the body of the working fluid.

There are many possible implementations of the Stirling engine most of which fall into the category of reciprocating piston engine.

History

Invention and early development

The Stirling engine (or Stirling’s air engine as it was known at the time) was invented and patented by Robert Stirling in 1816.[9] It followed earlier attempts at making an air engine but was probably the first to be put to practical use when in 1818 an engine built by Stirling was employed pumping water in a quarry.[10] The main subject of Stirling’s original patent was a heat exchanger which he called an “economiser” for its enhancement of fuel economy in a variety of applications. The patent also described in detail the employment of one form of the economiser in his unique closed-cycle air engine design[11] in which application it is now generally known as a “regenerator“. Subsequent development by Robert Stirling and his brother James, an engineer, resulted in patents for various improved configurations of the original engine including pressurization which had by 1843 sufficiently increased power output to drive all the machinery at a Dundee iron foundry.[12]

Though it has been disputed,[13] it is widely supposed that as well as saving fuel, the inventors were motivated to create a safer alternative to the steam engines of the time,[14] whose boilers frequently exploded, causing many injuries and fatalities.[15][16]

The need for Stirling engines to run at very high temperatures to maximize power and efficiency exposed limitations in the materials of the day, and the few engines that were built in those early years suffered unacceptably frequent failures (albeit with far less disastrous consequences than a boiler explosion[17]) — for example, the Dundee foundry engine was replaced by a steam engine after three hot cylinder failures in four years.[18]

Later nineteenth century

Subsequent to the failure of the Dundee foundry engine there is no record of the Stirling brothers having any further involvement with air engine development and the Stirling engine never again competed with steam as an industrial scale power source (steam boilers were becoming safer[19] and steam engines more efficient, thus presenting less of a target to rival prime movers). However, from about 1860 smaller engines of the Stirling/hot air type were produced in substantial numbers finding applications wherever a reliable source of low to medium power was required, such as raising water or providing air for church organs.[20] These generally operated at lower temperatures so as not to tax available materials, so were relatively inefficient. But their selling point was that, unlike a steam engine, they could be operated safely by anybody capable of managing a fire.[21] Several types remained in production beyond the end of the century, but apart from a few minor mechanical improvements the design of the Stirling engine in general stagnated during this period.[22]

Twentieth century revival

During the early part of the twentieth century the role of the Stirling engine as a “domestic motor”[23] was gradually taken over by the electric motor and small internal combustion engines. By the late 1930s, it was largely forgotten, only produced for toys and a few small ventilating fans.[24]

Around that time, Philips was seeking to expand sales of its radios into parts of the world where mains electricity was unavailable and batteries were not consistently available. Philips’ management decided that offering a low-power portable generator would facilitate such sales and asked a group of engineers at the company’s research lab in Eindhoven to evaluate alternative ways of achieving this aim. After a systematic comparison of various prime movers, the team decided to go forward with the Stirling engine, citing its quiet operation (both audibly and in terms of radio interference) and ability to run on a variety of heat sources (common lamp oil – “cheap and available everywhere” – was favored).[25] They were also aware that, unlike steam and internal combustion engines, virtually no serious development work had been carried out on the Stirling engine for many years and asserted that modern materials and know-how should enable great improvements.[26]

By 1951, the 180/200 W generator set designated MP1002CA (known as the “Bungalow set”) was ready for production and an initial batch of 250 was planned, but soon it became clear that they could not be made at a competitive price. Additionally, the advent of transistor radios and their much lower power requirements meant that the original rationale for the set was disappearing. Approximately 150 of these sets were eventually produced.[27] Some found their way into university and college engineering departments around the world[28] giving generations of students a valuable introduction to the Stirling engine.

In parallel with the Bungalow set, Philips developed experimental Stirling engines for a wide variety of applications and continued to work in the field until the late 1970s, but only achieved commercial success with the ‘reversed Stirling engine’ cryocooler. However, they filed a large number of patents and amassed a wealth of information, which they licensed to other companies and which formed the basis of much of the development work in the modern era.[29]

Functional description

The engine is designed so that the working gas is generally compressed in the colder portion of the engine and expanded in the hotter portion resulting in a net conversion of heat into work.[2] An internal Regenerative heat exchanger increases the Stirling engine’s thermal efficiency compared to simpler hot air engines lacking this feature.

Key components

As a consequence of closed cycle operation, the heat driving a Stirling engine must be transmitted from a heat source to the working fluid by heat exchangers and finally to a heat sink. A Stirling engine system has at least one heat source, one heat sink and up to five[clarification needed] heat exchangers. Some types may combine or dispense with some of these.

Heat source

The heat source may be provided by the combustion of a fuel and, since the combustion products do not mix with the working fluid and hence do not come into contact with the internal parts of the engine, a Stirling engine can run on fuels that would damage other types of engines’ internals, such as landfill gas which contains siloxane.

Other suitable heat sources include concentrated solar energy, geothermal energy, nuclear energy, waste heat and bioenergy. If solar power is used as a heat source, regular solar mirrors and solar dishes may be utilised. The use of Fresnel lenses and mirrors has also been advocated, for example in planetary surface exploration.[30] Solar powered Stirling engines are increasingly popular as they offer an environmentally sound option for producing power while some designs are economically attractive in development projects.[31]

Heater / hot side heat exchanger

In small, low power engines this may simply consist of the walls of the hot space(s) but where larger powers are required a greater surface area is needed in order to transfer sufficient heat. Typical implementations are internal and external fins or multiple small bore tubes.

Designing Stirling engine heat exchangers is a balance between high heat transfer with low viscouspumping losses and low dead space (unswept internal volume). With engines operating at high powers and pressures, the heat exchangers on the hot side must be made of alloys that retain considerable strength at temperature and that will also not corrode or creep.

Regenerator

In a Stirling engine, the regenerator is an internal heat exchanger and temporary heat store placed between the hot and cold spaces such that the working fluid passes through it first in one direction then the other. Its function is to retain within the system that heat which would otherwise be exchanged with the environment at temperatures intermediate to the maximum and minimum cycle temperatures,[32] thus enabling the thermal efficiency of the cycle to approach the limiting Carnot efficiency defined by those maxima and minima.

The primary effect of regeneration in a Stirling engine is to increase the thermal efficiency by ‘recycling’ internal heat which would otherwise pass through the engine irreversibly. As a secondary effect, increased thermal efficiency yields a higher power output from a given set of hot and cold end heat exchangers. It is these which usually limit the engine’s heat throughput. In practice this additional power may not be fully realized as the additional “dead space” (unswept volume) and pumping loss inherent in practical regenerators reduces the potential efficiency gains from regeneration.

The design challenge for a Stirling engine regenerator is to provide sufficient heat transfer capacity without introducing too much additional internal volume (‘dead space’) or flow resistance. These inherent design conflicts are one of many factors which limit the efficiency of practical Stirling engines. A typical design is a stack of fine metal wiremeshes, with low porosity to reduce dead space, and with the wire axes perpendicular to the gas flow to reduce conduction in that direction and to maximize convective heat transfer.[33]

The regenerator is the key component invented by Robert Stirling and its presence distinguishes a true Stirling engine from any other closed cycle hot air engine. Many small ‘toy’ Stirling engines, particularly low-temperature difference (LTD) types, do not have a distinct regenerator component and might be considered hot air engines, however a small amount of regeneration is provided by the surface of displacer itself and the nearby cylinder wall, or similarly the passage connecting the hot and cold cylinders of an alpha configuration engine.

Cooler / cold side heat exchanger

In small, low power engines this may simply consist of the walls of the cold space(s), but where larger powers are required a cooler using a liquid like water is needed in order to transfer sufficient heat.

Heat sink

The heat sink is typically the environment at ambient temperature. In the case of medium to high power engines, a radiator is required to transfer the heat from the engine to the ambient air. Marine engines can use the ambient water. In the case of combined heat and power systems, the engine’s cooling water is used directly or indirectly for heating purposes.

Alternatively, heat may be supplied at ambient temperature and the heat sink maintained at a lower temperature by such means as cryogenic fluid (see Liquid nitrogen economy) or iced water.

Displacer

The displacer is a special-purpose piston, used in Beta and Gamma type Stirling engines, to move the working gas back and forth between the hot and cold heat exchangers. Depending on the type of engine design, the displacer may or may not be sealed to the cylinder, i.e. it may be a loose fit within the cylinder, allowing the working gas to pass around it as it moves to occupy the part of the cylinder beyond.

Configurations

There are two major types of Stirling engines, that are distinguished by the way they move the air between the hot and cold sides of the cylinder:

  1. The two piston alpha type design has pistons in independent cylinders, and gas is driven between the hot and cold spaces.
  2. The displacement type Stirling engines, known as beta and gamma types, use an insulated mechanical displacer to push the working gas between the hot and cold sides of the cylinder. The displacer is large enough to insulate the hot and cold sides of the cylinder thermally and to displace a large quantity of gas. It must have enough of a gap between the displacer and the cylinder wall to allow gas to flow around the displacer easily.

Alpha Stirling

An alpha Stirling contains two power pistons in separate cylinders, one hot and one cold. The hot cylinder is situated inside the high temperature heat exchanger and the cold cylinder is situated inside the low temperature heat exchanger. This type of engine has a high power-to-volume ratio but has technical problems due to the usually high temperature of the hot piston and the durability of its seals.[34] In practice, this piston usually carries a large insulating head to move the seals away from the hot zone at the expense of some additional dead space.

Action of an alpha type Stirling engine

The following diagrams do not show internal heat exchangers in the compression and expansion spaces, which are needed to produce power. A regenerator would be placed in the pipe connecting the two cylinders. The crankshaft has also been omitted.

Beta Stirling

A beta Stirling has a single power piston arranged within the same cylinder on the same shaft as a displacer piston. The displacer piston is a loose fit and does not extract any power from the expanding gas but only serves to shuttle the working gas between the hot and cold heat exchangers. When the working gas is pushed to the hot end of the cylinder it expands and pushes the power piston. When it is pushed to the cold end of the cylinder it contracts and the momentum of the machine, usually enhanced by a flywheel, pushes the power piston the other way to compress the gas. Unlike the alpha type, the beta type avoids the technical problems of hot moving seals.[35]

Action of a beta type Stirling engine

Again, the following diagrams do not show internal heat exchangers or a regenerator, which would be placed in the gas path around the displacer.

Gamma Stirling

A gamma Stirling is simply a beta Stirling in which the power piston is mounted in a separate cylinder alongside the displacer piston cylinder, but is still connected to the same flywheel. The gas in the two cylinders can flow freely between them and remains a single body. This configuration produces a lower compression ratio but is mechanically simpler and often used in multi-cylinder Stirling engines.

Other types

Other Stirling configurations continue to interest engineers and inventors.

The rotary Stirling engine seeks to convert power from the Stirling cycle directly into torque, similar to the rotary combustion engine. No practical engine has yet been built but a number of concepts, models and patents have been produced for example the Quasiturbine engine.[36]

The hybrid between piston and rotary configuration is a double acting engine. This design rotates the displacers on either side of the power piston

Another alternative is the Fluidyne engine (Fluidyne heat pump), which uses hydraulic pistons to implement the Stirling cycle. The work produced by a Fluidyne engine goes into pumping the liquid. In its simplest form, the engine contains a working gas, a liquid and two non-return valves.

The Ringbom engine concept published in 1907 has no rotary mechanism or linkage for the displacer. This is instead driven by a small auxiliary piston, usually a thick displacer rod, with the movement limited by stops.[37][38]

The two-cylinder Stirling with Ross yoke is a two-cylinder stirling engine (not positioned at 90°, but at 0°) connected with a special yoke. The engine configuration/yoke setup was invented by Andy Ross (engineer)[disambiguation needed].[39]

The Franchot engine is a double acting engine invented by ‘Franchot’ in the nineteenth century. A double acting engine is one where both sides of the piston are acted upon by the pressure of the working fluid. One of the simplest forms of a double acting machine, the Franchot engine consists of two pistons and two cylinders and acts like two separate alpha machines. In the Franchot engine, each piston acts in two gas phases, which makes more efficient use of the mechanical components than a single acting alpha machine. However, a disadvantage of this machine is that one connecting rod must have a sliding seal at the hot side of the engine, which is a difficult task when dealing with high pressures and high temperatures[citation needed].

Theory

The idealised Stirling cycle consists of four thermodynamic processes acting on the working fluid:

  1. IsothermalExpansion. The expansion-space and associated heat exchanger are maintained at a constant high temperature, and the gas undergoes near-isothermal expansion absorbing heat from the hot source.
  2. Constant-Volume (known as isovolumetric or isochoric) heat-removal. The gas is passed through the regenerator, where it cools, transferring heat to the regenerator for use in the next cycle.
  3. IsothermalCompression. The compression space and associated heat exchanger are maintained at a constant low temperature so the gas undergoes near-isothermal compression rejecting heat to the cold sink
  4. Constant-Volume (known as isovolumetric or isochoric) heat-addition. The gas passes back through the regenerator where it recovers much of the heat transferred in 2, heating up on its way to the expansion space.

Theoretical thermal efficiency equals that of the hypothetical Carnot cycle – i.e. the highest efficiency attainable by any heat engine. However, though it is useful for illustrating general principles, the text book cycle is a long way from representing what is actually going on inside a practical Stirling engine and should only be regarded as a starting point for analysis. In fact it has been argued that its indiscriminate use in many standard books on engineering thermodynamics has done a disservice to the study of Stirling engines in general.[49][50]

Other real-world issues reduce the efficiency of actual engines, due to limits of convective heat transfer, and viscous flow (friction). There are also practical mechanical considerations, for instance a simple kinematic linkage may be favoured over a more complex mechanism needed to replicate the idealized cycle, and limitations imposed by available materials such as non-ideal properties of the working gas, thermal conductivity, tensile strength, creep, rupture strength, and melting point. A question that often arises is whether the ideal cycle with isothermal expansion and compression is in fact the correct ideal cycle to apply to the Stirling engine. Professor C. J. Rallis has pointed out that it is very difficult to imagine any condition where the expansion and compression spaces may approach isothermal behavior and it is far more realistic to imagine these spaces as adiabatic.[51] An ideal analysis where the expansion and compression spaces are taken to be adiabatic with isothermal heat exchangers and perfect regeneration was analyzed by Rallis and presented as a better ideal yardstick for Stirling machinery. He called this cycle the ‘pseudo-Stirling cycle’ or ‘ideal adiabatic Stirling cycle’. An important consequence of this ideal cycle is that it does not predict Carnot efficiency. A further conclusion of this ideal cycle is that maximum efficiencies are found at lower compression ratios, a characteristic observed in real machines. In an independent work, T. Finkelstein also assumed adiabatic expansion and compression spaces in his analysis of Stirling machinery [52]

So there you have some solution against these greedy monster electricity corporations. Just think about it. If everyone has this kind of engine in basement you can produce electricity when the main grid is down, and if you have Solar power available you can use that to heat up and start up your engine! Great stuff!
