I mean, it's an odd statistic. You can use U-235 directly, or you can burn it in an LWR, getting back just 1/5th its equivalent in Pu-239, and use that. If you're trying to maximize fissile input for fast breeders, LWR spent fuel isn't an e

> if we reprocessed all spent fuel in the U.S. today, we'd have enough Pu to power about 33 MWe worth of breeders, about 1/3 of the current fleet. That should be "GWe" not "MWe". Also, I dispute your choice of statistic. Why not show wh

The last link in the article seems to answer this: "A 100-kilowatt Bloom server array costs around $700,000 to $800,000, or $7,500 a kilowatt, after incentives that cover around 50 percent of the costs" http://www.greentechmedia.com/articl

It's both less efficient and more expensive than burning natural gas in a turbine. Its data sheet claims 52% efficiency [1], while current generation CCGTs are 60% efficient (e.g. [2]). Its commercial price is $7,000-$8,000/kW(e) [3]. This

It's a surprise because it's wrong. The author used an emissive power of 1,360 W/m^2 -- the intensity of direct sunlight -- as so: http://www.google.com/search?hl=en&q=(1,360+/+(5.67+*+10... But this isn't the right number to use. The

Oh no, it is the average value. You don't want to know the lowest value. Or if you do, go to the Spanish utility's site and browse statistics for the summer months, when wind is usually slower: http://www.ree.es/ingles/operacion/curvas_eol

Oh wow. I was just lurking here, and I see my own blog mentioned! I hate to be an exasperating pedant, but I am, and I must annoy you: "Spain only gets about 9% of energy from renewables on average," It's actually 9% of electricity from
