Several Massachussetts Institute of Technology breakthroughs will make solar power cheaper than coal, reported Kurt Kurkart at Mother Nature Network back in 2011, and they are no less relevant today. The breakthroughs were: first, azo-benzene molecules spaced by carbon nanotubes that convert and store solar energy at a density comparable to lithium batteries today, spaced by carbon nanotubes. Second, an engineered virus that acts as a nano-machine, spacing the nanotubes, and increasing efficiency. Third, a way to durably print solar cells on any surface inexpensively, using low temperatures and vapor – thermal powered personal computers, here we come! Fourth, tiny, nano-sized thermogenerators that can absorb far more of the solar radiation striking a solar thermal setup. Finally, transparent solar cells that will convert windows into power plants. And the breakthrough avalanche has not stopped. Latest breakthroughs include a new, cheaper way of producing the silicon used to make solar cells, and the spinning solar cell, a conical spinning solar panel that simultaneously absorbs far more radiation, and dispels waste heat. The big news here? Solar power can be cheaper than coal if we invest in it.
Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
