Following discussion here and on the wiki I have changed "power_type" to "power_output": http://wiki.openstreetmap.org/wiki/Proposed_features/power_type
I have also introduced a new tag proposal, "power_method": http://wiki.openstreetmap.org/wiki/Proposed_features/power_method This resolves ambiguities about what "solar thermal" means, retains the advances offered by my original proposal, and opens up a whole world of fun describing the method used by the generator to turn the fuel into useful energy. I have entered a limited set of power_method values, others might want to expand it. If any wiki enthusiasts want to change the name of the first proposal to "Proposed_features/power_output" and do something with the deprecated proposal currently occupying that URL, be my guest!
