Incidentally, it doesn't violate the 2nd law since the total entropy of the system (which includes the collector and the target) never decreases. The system as a whole is still losing energy.

Heck, for that matter, if you were to encompass the entire sun in an elliptical reflector with it at one focus, the other focus point would experience considerably more than the surface intensity. This system still loses energy though, since no reflector is perfect.

Really? If I have a translucent sphere with a smaller spherical source at the center, I have no way to determine by observation what the size of the inner source is, and thus no way to determine the surface intensity of the actual source. Furthermore, if I increase the size of the outer sphere, the apparent intensity at the surface decreases, but if I have a mirror array that fully encompasses it, the total collected flux remains the same.

Does that theorem perchance apply only to refraction not reflection?

By the way, you appear to have thoroughly missed the point of Atlas Shrugged.

But non-believers are by definition not innocent didn't you know?

And herein lies the problem with current hate crime legislation. According to the law, it's not possible to commit a hate crime against a white man, or a christian, or... (insert other dominant group here), at least not due to their membership in that group.

So if a white man kills a black man because he hates blacks, that's a hate crime. Whereas if a black man kills a white man because he hates whites, it's just murder.

That does mean that under current laws the life of a black man is considered to be more important than a white man. And here I thought that we were supposed to be striving for equality in this country.

First look at the breeding rate of all the different species we've driven extinct. Then compare to the reproduction rate of mosquitoes. Also compare the food sources and available habitats.

Problem with driving mosquitoes extinct is that they are among the (relatively) few species on the planet that can live almost anywhere we can, and regards us as food. It also only takes a few of them surviving, and then with their reproduction rate they're back very quickly in that area.

I'm not saying it couldn't be done, but it's be a bitch to do and there'd be a lot of bykill that we don't really want. It'd also take out a very low level creature in the foodchain.
