That's a Lot of Juice

Ray Kurzweil on solar power:

“We also see an exponential progression in the use of solar energy,” he said. “It is doubling now every two years. Doubling every two years means multiplying by 1,000 in 20 years. At that rate we’ll meet 100 percent of our energy needs in 20 years.”

And what about our cars?

“You could, for example, create hydrogen or hydrogen-based fuels from the energy produced by solar panels and then use that to create fuel for fuel cells, he said. There are already nano-engineered fuel cells, microscopic in size, that can be scaled up to store huge quantities of energy, he said.

I certainly hope he’s right.
