</div>But there is a difference between using a steam turbine, a sterling<br>
engine or a magnetohydrodynamic generator, but all these can be fired<br>
by coal or fission.<br>
<br>
Fission energy could be used by heating water to power a steam turbine<br>
or by using a radioisotope thermoelectric generator or a betavoltaics.<br>
<br>
Fission power plants could use 'clean' uranium 238 or (with a special<br>
license) a plutonium uranium mixture (MOX) or Thorium MOX.<br></blockquote><div> <br><br>All that is true.<br><br>It is also the case that some parks are surfaced with perennial ryegrass whilst others make more use of fescue varieties. But it doesn't follow that somebody proposing tags for parks should start out with such a level detail before using leisure=park. We don't have leisure=park-with-70-percent-perennial-rye-grass-and-30-percent-creeping-red-fescue, do we?<br>
<br>I proposed the range of generation methods in the wiki, with suggestions and contributions from other mappers, because the itch I want to scratch is: "how environmentally sustainable is this power generator?" I was also mindful of the sorts of information generally valued by people who actually work in the energy and built environment industries, i.e. what they would want to know when they asked "what sort of generator is this?"<br>
<br>The tagging schema, as proposed, allows us to answer those questions and meet some other general needs proposed by other mappers. It does so without requiring mappers to necessarily enter this level of detail -- they can simply tag an object as power=generator and be done with it.<br>
<br>If you want to extend the proposal to reach a further level of detail - the precise chain of processes used to turn the generator:source into the generator:output - then by all means write out such a proposal.<br><br>
If you can do so without requiring that mappers happy with generator:method=gasification be forced to instead enter a more complicated mixture of tags to describe those precise processes, then I wouldn't argue against your proposal. It wouldn't interest me, but it also wouldn't get in my way.<br>
