This project is interesting but all comparisons are fair with the end in mind, which is the cost per MWh or per "home" over its life. If you need 55 of those to produce 250MW you'll have to multiply the costs by 55 as well. Power also has to be available all the time, when there is no sun, no wind, no waves, etc. Nuclear and gasoline are sadly the top picks because of energy density (and in the case of gasoline also portability).
