Hairy Solar Cells Could Mean Higher Efficiency 203
kitzilla writes "Two research groups working independently have come up with what they say are cheap processes for growing nanowires to be used with solar cells. The 'hairy' cells provide a direct path for electrons collected at the panel face to reach an electrode, something which has the potential to dramatically improve system efficiency."

Give this technology another 20-30 years, maybe even less, and the advancement of production will drop the price.

Generally solar is good as long as the sky is clear. Imagine what would happen to a 100% solar economy hit by a month of thick clouds. I don't think relying on something as random as the weather for your main energy supply is a good idea. It's OK e.g. when you want to power farm machines, because if there's no power you can wait, but powering cities with it doesn't seem wise. I also think that green activists should stop pretending they can do without nuclear power (at least those of them that do), because right now they can't, and telling everybody not to invest in nuclear and wait until we come up with adequate energy storage technology is making the global warming worse by preventing substantial CO2 emission reductions.

I don't see its proved anything of the sort to be honest. Unless the poster who made the original suggestion is in a position to bring this product to market himself, and was willing to make what I assume would be a large investment to do so without the benefit of any patent protection, then no one has lost anything. On the flip side the patent holder may be able to find an investor willing to back development of the technology; it would be considerably harder to do so if the investor knew that if the product was a success, they'd have to very quickly face competitors selling identical products who didn't have to make as large an initial investment.
Disclaimer: I know crap all about solar power or the validity or utility of this particular patent; I'm just trying to make a distinction between the development of software and that of physical inventions.
