Thanks again for the information. Didn't these just dissipate heat by venting the steam to the atmosphere? That seems wasteful.

Those locomotives were made around 1940. They ran at 80mph max speed. All locomotives of the Big Boy model worked for at least 20 years, and retired only because of arrival of more competitive diesel electric engines. The numbers are impressive compared to Rossi's plant. Those beasts were able to dissipate huge amounts of heat, since their thermodynamic efficiency was below 10% most of the time. Yet they were reliable machines. Rossi will have no safety problems with steam, assuming that he followed those ancient engineering lessons. There is no reason for him to use hot water. I guess the idea is some kind of district heating plant (http://en.wikipedia.org/wiki/District_heating) using steam. Then do the scale up to electrical power when eventually E-cat will be able to support it. mic 2011/10/19 David Roberson <dlrober...@aol.com>: > The power requirements for a large truck are enormous.
