He may be off a bit on the factor of 30. In Ontario, solar is paid about 70 cents per kWhr, while nuclear gets about 6. So it's round about a factor of 10 or 11 here. Similar numbers apply in Europe, though the "base" generation load is more expensive there. Plus, in both of those areas, there are 20 year or more contracts to buy as much power as the solar plants can produce. Now, that 70 cents gets bumped up a bit for transmission costs. So by the time it makes it to your wall plug it's about 75, plus taxes and fees. Imagine that. You run your computer for 10 hours, and your electric bill is $3 or $4. Even at those rates the solar plants are not huge money makers. If required to pay property taxes on the actual costs of their installs, most plants in Ontario don't make a profit. Still, it has been ample payment for motivation of the cheaters. It has been discovered that several Spannish solar farms had outputs that did not fall when the sun did. Turns out, they had diesel generators in sheds, and fired them up as light levels fell. Now, diesel is more expensive than typical generation from large electric plants, such as coal or gas fired, or nuclear. But it's way cheaper than what the solar plants get paid. They were getting away with tweaking up their losses from clouds. But they didn't account for the change of dawn and sunset times as the seasons changed, and so got busted. Socks

Include the rights of way. thus: yeah, that's the spirit. the problem is, in developing a model of n-dimensional figurate numbers, that could be used to make the F"L"T contradiction. (Conway and Guy had a nice, elementary "Book of Numbers" -- as I recall -- with lots of pictures for 3D figurates; I even made some "new results" using it .-) thus: the actual problem was in 1895, when Svente Ahrrhenius didn't bother to model an actual glass house at a particular lattitude ... and neither did anyone who had a computer in the climate lab. on the other hand, he probably didn't get the first Nobel for *that*, any way. thus: you mean, F"L"T is easy for the Sophie Germaine primes? thus: in contrast to Magadin's assertion, below, the reality is that n=4 is the only case that is truly special, which Fermat apparently didn't notice, when he wrote the marginal note. (may be, that's what blew him off, when I noted it in another item .-) Fermat apparently did not have to prove n=3, 5 etc., nor any other composite power (the "easy lemma" in all elementary treatments of numbertheory with F"L"T .-) thus: .... but, he did see one key (old) result, that Fermat's "last" theorem is the same, when applied to rational numbers, as pairs of coordinates on the unit circle (or the associated Fermat curves, for powers greater than two. well, it's quite trivial, as they say, but it is a good way to attempt the problem, a la Ribet, Frey etc. through to Wiles' Secret Attic Project. there's a really good expository book on the stuff around Wiles "proof," _Fearless Symmetry_. thus: since Fermat made no mistakes, at all, including in withdrawing his assertion about the Fermat primes (letter to Frenicle), all -- as I've posted in this item, plenty -- of the evidence suggests that the "miracle" was just a key to his ne'er-revealed method, and one of his very first proofs. (and, I wonder, if Gauss was attracted to the problem of constructbility, after reading of the primes.) --Light: A History! http://wlym.TAKEtheGOOGOLout.com

Wassamatta "Sam"? Actual scientific analysis more than your AI program can handle? Tell us how you feel about truthful analysis of costs.

Your lack of success is due to this evil conspiracy of status-quoists, not any fundamental defect in the economics of your business model. It's a conspiracy of the oil companies and the Freemasons!
