First, the good news. Here it is - in print. Too bad it is not coming from someone with the credibility of Tom Darden/IH.
https://www.ecat.tech/ The site presents a fabulous first impression - especially for those who have never heard of Roger Green. The specs are listed - and basically there is a "guaranteed" COP of 6:1 which is 1 megawatt of heat out and an average of 167 kW electrical in. Fabulous even if they measure the fuel in "barrows". If this datum were to be true - Roger cannot make them fast enough and the world is suddenly a much different place (especially the norther latitudes of which he only has Korea as a prime zone). Let's give the Rossi's fan-boys time to gloat in the warm-regards of Roger's premature announcement - before mentioning the bad news.
