Stephen Rand, a researcher and proffessor at the University of Michigan may have just casually overthrown 100 years of physics with his team’s new approach to harnessing solar energy.
The key to the breakthrough is the magnetic properties of light, which scientists thought negligible for years. But the researchers found that when light passes through a material that does not conduct electricity — such as glass — it has magnetic affects 100 million times stronger than anticipated.
That’s a big number, and it might have huge repercussions for solar cell manufacturers. Rand said:
In solar cells, the light goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load. Instead of the light being absorbed, energy is stored in the magnetic moment. Intense magnetization can be induced by intense light and then it is ultimately capable of providing a capacitive power source.
I guess making solar power more economically viable is a good thing. Full story at Geekosystem
