Ask HN: Why aren't we spending more time to research harnessing solar energy?
I just watched this movie<p>http://www.youtube.com/homeproject<p>This fact shocked me:<p>In one hour the sun gives the earth the same amount of energy as that consumed by all humanity in one year
(Fast forward to around 1:26:20)<p>That is a staggering amount of energy.  Shouldn't we be spending more resources in trying to build, say a solar car, than an electric car?
