Rossi recently said, “We have found a breakthrough with a primary fluid with wich the reactors remain stable when we make steam at 450 Celsius. ” (http://www.e-catworld.com/2011/11/andrea-rossi-working-with-domenico-fioravanti-on-electrical-power-from-e-cat/#comment-9822)
This is lots of heat for efficient steam power! The CyclonePower steam engines run at temperatures as low as 260c (500f) http://www.cyclonepower.com/whe.html With the ability to output 450c, we are seriously in the zone of seeing a steam powered custom car in 2012.
This also shows that continuing enhancement path that I discussed under A Case for Rossi.
