They could possibly turn a working fluid into plasma, driving an MHD generator. This needs a fair bit of work in developing large-scale non-imaging optics and in developing thermal radiators for use in space (though the techniques should work here just as well). I wonder how such a system would compare with other solar generation schemes. -- Nick_Janow@mindlink.bc.ca
