Andrea Rossi is a convicted white-collar criminal with a string of failed energy ventures. (
Report #5: Rossi's Profitable Career in Science) His most notorious endeavor was his effort between 1970 and 1990 to turn industrial waste into fuel. Rossi's company produced nothing but toxic waste and environmental damage to the land and groundwater in the Milan, Italy, area. (
Rossi's Italian Financial and Environmental Criminal History)
In 2007, Rossi began trying to use and commercialize the low-energy nuclear research of Francesco Piantelli, a retired Italian biophysicist. Piantelli began his LENR research in 1989, when he observed something unusual taking place in one of his experiments. Initially, Piantelli didn't pay close attention to it. But after he saw the Martin Fleischmann and Stanley Pons "cold fusion" announcement, he looked more closely at his own work. Piantelli found that his device, too, was producing anomalous excess heat and nuclear effects. But Piantelli was working with nickel and hydrogen gas, a very different configuration from Fleischmann-Pons. (

Piantelli also knew that the idea of room-temperature fusion was highly unlikely. More significantly, he was working with a hydrogen system rather than a deuterium system; therefore, the idea of fusion was not even a consideration for him. (See 2008 and 2010 ACS presentations here

For many years, Piantelli worked with his colleague Sergio Focardi in LENR research. Both men have legitimate academic credentials and scientific backgrounds. Together, they have a long history of credible LENR research, some of which published in peer-reviewed journals. The pair never got fully reproducible or practical results. (

I met Piantelli and interviewed him in his private lab in 2007. Both he and Focardi were retired by then. I wrote two articles about their work the following year. Right around that time, Rossi approached Piantelli and asked to work with him. Meanwhile several Americans, began asking for my assistance to make contact with Piantelli.
Piantelli declined Rossi's offer to collaborate. Rossi approached Focardi, who had given up research at the time and was eager for a second chance.

There is no hard evidence of any research the two performed together. According to Focardi, he and Rossi performed their
first experiment on Oct. 16, 2007. However, Focardi's photograph of that event shows a date stamp of
