Andrea Rossi (entrepreneur)

In 1974, Rossi registered a patent for an incineration system. In 1978, he wrote The Incineration of Waste and River Purification, published in Milan by Tecniche Nuove. He then founded Petroldragon, a company that was paid to process toxic waste, claiming to use Rossi's process to convert the waste into usable petroleum products.[15] In 1989 Italian customs seized several Petroldragon waste deposit sites and assets. Investigations showed that petroleum supposedly produced by the company had never been placed on the market, and that mixtures of toxic waste and harmful chemical solvents were being stored in silos or illegally dumped into the environment.[4][16] Rossi himself was arrested and eventually tried on 56 counts, 5 of which ended in convictions related to tax fraud. As of 2004 the government of Lombardy had spent over forty million euros to dispose of the 70,000 tonnes of toxic waste that Petroldragon had improperly dumped.[17]

In the US Rossi started the consulting firm Leonardo Technologies, Inc. (LTI). He secured a defense contract to evaluate the potential of generating electricity from waste heat by using thermoelectric generators. Such devices are normally only used for heating or cooling (Peltier effect), because the efficiency for generating electrical power is only a few percent. Rossi suggested that his devices could attain 20% efficiency. Larger modules would be manufactured in Italy. Rossi sent 27 thermoelectric devices for evaluation to the Engineer Research and Development Center; 19 of these did not produce any electricity at all. The remaining units produced less than 1 watt each, instead of the expected 800–1000 watts.[18]

In January 2011, Andrea Rossi and Sergio Focardi claimed to have demonstrated commercially viable nuclear power in a device he called an Energy Catalyzer. The international patent application received an unfavorable international preliminary report on patentability because it seemed to "offend against the generally accepted laws of physics and established theories" and to overcome this problem the application should have contained either experimental evidence or a firm theoretical basis in current scientific theories.[19]

In February 2012, Australian aviator and skeptic Dick Smith offered Rossi US$1 million if Rossi could prove his device generated output many times input, as he had claimed. The offer lapsed, Rossi having declined to take up the challenge.[20]

In 2014, US company Industrial Heat LLC acquired rights to the device, but later became involved in a legal dispute with Rossi, who asserted that licensing fees had not been paid. Industrial Heat countered that they had been unable to reproduce the claimed results, and the case was eventually settled out of court on undisclosed terms. [21] [22]
