I suppose he is speaking of methane. No need for electrical power anymore. Seems that Rossi is leaving "competition" in the dust. Read below.

We are very close to a 1 MW plant with high temperature steam and electric power generation. Another important achievement , we got today: we are able, now, to make the drive with gas instead of electric power. This is extremely important, because now we are able to make thermal energy with thermal energy, and with the thermal energy produced we can make electric power. All this with 1 MW plants. Warm Regards, Andrea Rossi mic
