'''Dennis Lee''' is an American independent inventor, businessman and free-energy promoter best known for his claim that useful electrical power can be extracted from ambient environmental heat by coupling a high-efficiency heat pump to a '''low-temperature phase-change engine'''. From the mid-1980s onward he toured the United States giving large public demonstrations of machines he described as producing more energy than they consume, and he built a network of paying dealerships around a succession of ventures — United Community Services of America, Better World Technologies, the International Tesla Electric Company and Better World Alternatives. He presented his low-temperature phase-change work to the independent-inventor community at the 1995 ''ExtraOrdinary Science'' conference run by the International Tesla Society, the predecessor of [[Tesla Tech]].

Lee is also the subject of an extensive and well-documented record of criminal convictions and state and federal regulatory actions arising from the marketing of these technologies, set out in the legal history section below.

==Biography==
Lee is based in New Jersey; his companies have operated from Newfoundland, New Jersey. ''Forbes'' described him in 2005 as 59 years old, and reported his account that he had at one time built a business worth some $50 million employing hundreds of people. In 2015 he legally changed his name to '''Josiah David''', the name under which his later business activity was conducted.

His entry into energy work was through heat pumps. Lee has said that he invented what he regarded as the world's most efficient heat pump, and that his efforts to bring it to market were sabotaged, his company taken from him, and he himself imprisoned as a result. That account of suppression — of a workable technology kept out of the marketplace by established interests — has remained the organising theme of his public presentations ever since.

From the mid-1990s Lee conducted extended demonstration tours. The best-documented is the thirty-four-city tour whose finale was held on 23 September 1996 at a Philadelphia city hockey stadium; the engineer Eric Krieg, writing in ''Skeptical Inquirer'' in 1997, described a five-hour demonstration of an array of machines, audience members signing "declarations of energy independence", and an offer of dealerships at $10,000. Lee's presentations combined technical demonstration with an explicitly religious and patriotic framing, and his literature quotes what he describes as revelations given to him by God. Lee has stated that he stopped selling new dealerships in 1990 after placing roughly 2,000 of them; dealership prices reported in state filings and in ''Forbes'' ranged from a few hundred dollars to $100,000, with dealers entitled to free electricity once the technology was completed.

==Scientific contributions==
Lee's central technical claim concerns '''low-temperature phase change'''. In outline, a working fluid with a very low boiling point is vaporised by low-grade heat drawn from the ordinary environment — air, water or soil — and the expanding vapour drives an engine; the fluid is then condensed and recirculated. Lee's contention is that when such an engine is paired with a sufficiently efficient heat pump, the coefficient of performance of the pump is high enough that the combination becomes self-sustaining and yields surplus electrical output. He has attributed the phase-change machine itself to the inventor Fischer, and has presented the heat pump as his own contribution.

Lee has stated that he possesses a motor that puts out roughly five times as much energy as is required to run it, and separately a generator that he describes as one hundred per cent efficient, and that connecting the two produces free electricity. He has not publicly demonstrated the two devices operating in combination. Asked by ''Forbes'' why he had not done so, he replied: "If I did do that, I'd have to tell you I've done that, because God hates a liar." These are claims Lee makes; they are recorded here as his position and have not been independently verified.

The generator marketed from the late 1990s under the name '''Sundance''' was promoted as feeding electricity back into the utility grid, so that a householder's meter would run backwards. Later ventures extended the same over-unity premise to other product lines: a '''Hydro-Assist Fuel Cell''' said to electrolyse water into a gas with several times the potential energy of gasoline and to convert any vehicle into a hybrid, a detergent-free magnetic laundry system, an insulating paint substitute, and a vibration-free jackhammer.

The claims fall outside what conventional thermodynamics allows: a closed cycle drawing heat from a single ambient reservoir and returning net work is excluded by the second law, and the fuel-cell claim conflicts with the energy accounting of electrolysis. Lee's own answer to this has been that his critics argue from theory rather than from his hardware, and that the technology has been actively suppressed. Independent measurement of the devices has not been permitted at his demonstrations; Krieg reported that he and colleagues brought electrical instruments and a Geiger counter to the 1996 Philadelphia event and were not allowed to use them.

==Legal history==
Lee has a substantial documented history of criminal convictions and of civil and regulatory actions brought by state attorneys general and by federal agencies, arising from the sale of dealerships and products connected with the technologies above. The account below is drawn from court decisions, state attorney-general announcements and federal enforcement records.

===Criminal convictions===
* '''California, 1990.''' Lee pleaded guilty to charges arising from the marketing of an energy-saving heat pump kit — described by the Securities and Exchange Commission as fraud and failure to disclose information in a marketing plan, and elsewhere as felony consumer fraud and violations of California's Seller Assisted Marketing Plan law — and was sentenced to two years in state prison. ''Forbes'' reported that California prosecutors had originally charged him with 47 violations for overstating the energy savings of an electric heat pump.
* '''Kentucky, 2004.''' Lee pleaded guilty to failing to register a business opportunity. The charge followed his arrest in Louisville, announced by Attorney General Ben Chandler on 9 October 2001, on a citation charging one count of failing to register a business opportunity, one count of omitting the registration number from advertisements, and one count of making earnings claims, each a Class C felony under the Kentucky Business Opportunity Act. A $50,000 cash bond was set. Chandler stated that his office had contacted Lee before his arrival in Kentucky to advise him of the state's requirements "and he failed to comply." Related litigation over the Jefferson County grand jury proceedings reached the Kentucky Supreme Court in 2003.

===Civil and regulatory actions===
* '''Washington, 1985.''' Lee was permanently enjoined from selling energy-related products, following state action over a "Solar Utility Network" promotion in which consumers were told they could cut electricity bills by 70–80 per cent.
* '''Washington, 1999–2006.''' The Department of Financial Institutions ordered him in October 1999 to stop selling unregistered securities in a claimed perpetual motion machine. In August 2001 the Attorney General sued Lee and United Community Services of America over the Sundance generator, alleging the technology had not been shown to exist and that dealerships valued at $30,000–$100,000 were being sold against 10 per cent "good faith deposits". In November 2002 he was ordered to pay $6,000 in civil penalties and approximately $59,000 in costs and attorneys' fees. In February 2006 the state petitioned the court again, alleging that a 7 February 2006 presentation at the Seattle Public Library violated the 2002 order.
* '''Alaska, 2001–2006.''' The state sued Lee, doing business as United Community Services of America and Better World Technologies, for deceptive advertising after he advertised a demonstration of "new revolutionary technologies" including a generator providing "free electricity". The superior court entered liability-establishing discovery sanctions, imposed $30,000 in civil penalties plus costs and fees, and enjoined him from making unsubstantiated product claims. The Alaska Supreme Court affirmed in ''Lee v. State'' (Docket S-11396) in August 2006.
* '''Maine, Oregon and other states, 2001.''' Maine permanently enjoined him from selling dealer units, discount clubs or products; Oregon permanently prohibited him from offering investment opportunities. Temporary restraining orders barring his presentations were also obtained in further states. ''Forbes'' reported in 2005 that Lee and associates were permanently barred from performing demonstrations in Maine, Kentucky, Idaho and Tennessee.
* '''Federal Trade Commission, 2009–2011.''' The FTC sued Lee, Dutchman Enterprises LLC and United Community Services of America over the Hydro-Assist Fuel Cell, alleging that claims of a 50 per cent or greater mileage improvement and of "water gas" with five times the energy of gasoline defied established physical principles. A settlement order entered on 7 December 2011 banned the defendants from selling energy generation or conservation products.
* '''Securities and Exchange Commission, 2021.''' The SEC charged Premier Healthcare Solution, LLC and its founder Josiah David, "formerly known as Dennis Lee", with fraudulently raising nearly $4 million from more than 130 investors from July 2017 onward through the sale of membership units. The complaint, filed in federal court in New Jersey, alleged misrepresentations about a bank loan and about patent status, and further alleged that David concealed and lied about his prior criminal and regulatory history from the period when he was known as Dennis Lee. The matter concerns a medical reimbursement business rather than energy technology, and is noted here because it is the source that establishes the connection between the two names.

===Lee's own position===
Lee has consistently maintained that he is the target of a co-ordinated effort to keep his technologies off the market. He told his 1996 Philadelphia audience that he had been victimised by a large-scale international and multigenerational conspiracy to suppress such technologies, and has said that his heat-pump company was taken from him and that he was imprisoned as a result of that campaign. He has attributed the 2004 civil suit he brought against the engineer Eric Krieg, seeking $1 million and alleging stalking and libel, to the same pattern of organised opposition. Where he has been asked directly why the combined device has not been demonstrated, his answer has been the religious one quoted above.

This record is set out because it is part of the documented public record. It is separate from, and does not by itself settle, the technical question of whether the effects Lee reports are real — as with the parallel case of [[Joe Champion]], the two questions are best kept distinct.

==TeslaTech==
Lee took his low-temperature phase-change work to the independent-inventor conference circuit organised by [[Steven R Elswick]], then operating as the International Tesla Society and later as [[Tesla Tech]].

At the ''ExtraOrdinary Science'' conference held 20–23 July 1995 at the Sheraton Hotel South in Colorado Springs, Colorado, he gave two presentations:
* "World's Declaration of Energy Independence" (catalogue no. TE9515)
* "Low Temperature Phase Change Technology" (catalogue no. TE9524)

Both remain listed in the [http://www.teslatech.info/ TeslaTech] conference archive.
