Mean Green

I'm a fan of green power. It only makes sense to harness what you can for energy. You never know when the grid may go down in a disaster and cutting your power bill is always a good thing. The drawback has always been bang for the buck. That was especially true with solar. Efficient panels are expensive and to be honest, not that efficient.

That may be about to change.

Scientists at Lawrence Berkley National Laboratory have announced a breakthrough with a high efficiency solar cell that can work... in the dark! The new full spectrum solar cell can capture lower bandwidth light like the moon, stars and other energetic sources. Scientists at Ohio State have a second generation panel in the works that improves performance loss due to heat.

In the meantime you can just grab a few cans of  photovoltaic spray paint. That's right, turn the barn into a battery!
