Yeah, fingers crossed for this one, although as someone pointed out (i think it was the register) it makes normal heat sources like burning coal more efficient too, so its not just a good news story for solar. Watch this space to see if it comes to something or not. I think we also have to factor in the energy consumed in actually constructing these things as well in the "how good is it really" calculation. What is effectively a big kettle an a turbine isn't *that* intensive to make and lasts a long long time, this may take more effort and not (initially) have the lifespan.

All new things like this are cool though and even if it dosent become the next big thing in power generating there are probably a lot of cool uses for it. Spaceships transmitting power by infrared laser anyone :]
