Some scientists have recently succeeded in creating a composite structure capable of absorbing 99% of microwaves directed at it, converting the received energy into heat rather than re-emitting the microwaves.

Re: Electromagnetic Black Holes
Does this have implications for Solar Energy?

Re: Electromagnetic Black Holes
It might be possible to utilise this for microwave power transmission. If scientists succeed in creating an equivalent that operates within the visible/IR range then it might have some implications for solar power - although I'm not certain whether you'ld be able to use this to generate electricity directly.
