Not sure if you read my post on this. Since large quantities of hard
radiation pass right through objects, that which passes thru obviously
doesn't impart any energy, so your efficiency relative to total flux
drops as frequency rises. You'd have to develop a sort of MHD system for
x-ray/gamma ray streams.
