World Energy Hits a Turning Point: Solar That's Cheaper Than Wind
I have high hopes for ARES [1]. just a heavy train on a hill with a regenerative break. Add lots of tracks, multiple trains per track, solar above the rails. Avoids needing all the water for pumped hydro storage. none of toxic stuff to deal with when batteries have reached their end of life. Zero carbon emission (aside from whatever is required for manufacturing) is just hugely appealing.<p>If solar prices continue as they have for another 3-5 years, the question is going to be pretty clear, how do we store all of this insanely cheap power. I'm a little mystified we're not taxing carbon emissions and subsidizing storage. But hey, there are clearly powerful forces at play, that don't agree with me.<p>[1] <a href="http://www.aresnorthamerica.com/" rel="nofollow">http://www.aresnorthamerica.com/</a>
