It's "free", that is, the money has already been stolen from you) is a description of a sunlight-pumped laser. Not too efficient - perhaps 1%, but there is a LOT of sunlight in space.

In general this rag has about 6 neat ideas and a few hundred stupid ones every three months; worth a look in your library...
