Cheap solar using holographic collectors
Apr. 26th, 2006 01:10 pmHere's a cool green-energy technology that looks to bring the cost of solar PV down nice and sharply.
Current PV is expensive because the silicon is expensive and so are the lenses and mirrors which collect light. By using sticky holograms - just like fancy birthday-present stickytape - light is collected without all that heavy precision glass, and since you collect the light you can use less silicon.
Though I gotta say, "holographic light collectors" sounds a lot cooler when you think of it as a huge projectable 3D image that bounces light. I mean, that'd rock.
