Steam is steam. The properties of steam don't change depending on where their origins are. Steam behaves the same if it comes from radioactive fuel rods or from the earth's natural core. So the comparison really starts looking silly.
I was thinking more about this last night and how when you really really really start to crunch the numbers of nuclear, oil or coal driven steam turbines, you really get a feel for how truly expensive each of these industries really is.
First of all, to acquire uranium, you need fuel-guzzling machines to mine it, house it, transport it, and store the waste. All those extra and necessary employees needs to handle this nasty power source are burning up fuels in commutes, they are making more worker's compensation claims...etc. etc.
With oil, well, just tally up how expensive it is to be in Iraq expanding the empire, let alone shipping, trucking the oil to refineries, the refining process itself, all those employees, safety issues at the refineries that like to explode from time to time..compensation claims...etc etc.
Then with coal, you have the most hazardous occupation next to Alaskan Crab fishing. Machines are used to mine, scores of workers commuting to and fro, hazards, black lung, transportation of coal. Belching smokestacks. (China largely uses coal...don't you love their air quality?....Clean coal my butt..) worker compensation claims...and so on...
Phenominally expensive "The Three Nasties" I like to call them.
And what is the goal of all three? To produce steam to run turbines.
The cost to MW ratio of geothermal, where there is no secondary source to turn water... to pre-existing steam.. AT SITE is the most efficient of all. If you had all the numbers of the The Three Nasties in front of you vs the numbers of geothermal costs per MW, you would die laughing at the stupendously ridiculous comparison.
Then you would get mad when you realized that the whole reason we haven't been using geothermal for the last four decades is because its widespread implementation and potential has been beaten back by negative BigOil/nuclear/coal (same people usually) PR campaigns painting out geothermal as "ridiculous".
How ironic that it is exactly the opposite.
