1MW standalone powerplants are generally used for backup power, or providing power to remote locations like mining or reasearch facilities that are “off the grid”. It sounds like in those applications using one of these cold fusion units will still require putting in some kind of conventioal fuel 200KW power plant to provide the input to maintain the reaction. Does the $1.5M include the cost of installing that?
If you have to put in 200KW of electricity to get 1000KW of heat, it may not matter much, Unless it is putting out very hot steam, you are going to have trouble getting past break even. I don’t have a Carnot chart handy but you may have trouble generating 200KW of electricity even if the thing actually works. If it is only putting out low quality steam, good for only heating, you would be better off running a heat pump with that 200KW.
And no, I don’t know what is included in the package, I suspect little more than rainbows and unicorns but the idea is intriguing enough to keep me clicking on the articles.
