Re: Update on twaddle generator
if you use cogeneration, and/or being that it's currently winter [so the extra heat generated by the cores _could_ be used to keep the rooms warm] then you're not wasting any of that energy...
[even though I wholeheartedly DIS-agree with the last (OT) sentence in your post]
I never have to heat my home office, when there are 3 computers doing it for me. It's 1-2 degrees F warmer than the rest of the house... [especially the bedroom which has 2 walls facing the elements - I have to use an electric heater so I don't freeze at night and wake up sick every morning]
Co-generation is such a good idea, I'm surprised more people aren't doing it. A perfect example is when you use natural gas to make eletricity, and THEN use the heat from the engine to heat water [which you would be doing anyway with the same amount of natural gas]. Extra electricity goes onto the grid. Also, hot water from the engine jacket can be used to run an 'absorption chiller' for the summer when you need chilled water. If this were done by municipalities, who could then sell the hot/chilled water and/or steam along with the electricity, it would make a really good efficient solution, one that consumes very little additional fuel over JUST making the hot water.
Similarly, a data center with co-generation COULD [in many ways] do the same kind of thing. It would make the technology cost less, and probabably make the climate change crowd happier because it's not using as much fossil fuel any more. Or if it were (in part) solar, using solar heated water and solar electricity for the building, same basic idea. Ah, hell, just combine the technologies to handle peak demands in summer/winter as well as bad weather days... so yeah not really a problem to use "all that power" when you make good use of the waste heat.
/me re-considers moving the server into the bedroom, at least during the winter.
