If you believe Al Gore, for $90MM you can build a giant New Mexico wind/solar farm that would supply enough electricity to power the entire US. (It's been a while since I saw the presentation so some details might be wrong but I am at least in the ballpark, especially regarding the price tag). Seems like 10 VC firms could easily get that sort of money together.
90 Million? The entire US? That's way off. I haven't seen the numbers, but that's like saying a car engine can get 1500% efficiency, or that a ten-year-old neighbor can bench-press 2000 pounds. It's just not in the cards.
