Frickin' Laser Beams

Solar Cells Could Get Quantum Boost

New advances in quantum optics have led theoretical physicists to believe they can produce more powerful Photovoltaic solar collectors. Using very precise lasers and effect known as quantum interference can makes electrons more powerful to then be harnesses into electricity. I would like to see if this is possible in the real world. Until now, most PV systems are between 15-20% efficiency, compared with 30%+ for hot water systems. If we can get PV systems to 30% efficiency, you will finally start to see people making the switch from current electric sources in greater numbers.
