CdTe = 0.22 g/W     http://www.ijcea.org/...
= 4545 W/kg
cf      = 0.19
Yr 1   = 7,565,455 Wh
Life    = 15 years
= 113 MWh/kg

If I did all of my math right (no guarantee on that, I'm an engineer ;) then that is about 68 times the energy density of 40 GW-days/MTHM.

See, where I would have made my argument is whether these numbers have any actual meaning. I'm not convinced they do.

Causation was, is, and ever shall be a slippery bitch, so we're best sticking with noting the facts

If you want to count only the active components then I should point out that each fission of 235U results in 200 MeV of energy. Since the atomic weight of this isotope is 235.044 g/mol, this means that fissioning 235U results in an energy yield of 22,800 MWh/kg, and you don't have to wait 15 years to get it all. For the record, that's over 200 times the energy density of your 15-year CdTe estimate.

Anyhow, I agree with you on one thing: none of this matters worth squat. The economics are based on factors that haven't been touched on here, and this is more of an exercise in mental masturbation than anything else, which is why you and Rei keep moving the goal posts -- because you can.

An idealist is one who, on noticing that a rose smells better than a cabbage, concludes that it will also make better soup.

I'm the one moving the goalposts? Dream on, brother, dream on. I'm gently trying to coax you into making a cogent argument.
