I don't think you need the rectenna at all. According to the wiki page the actual rectification is done by a diode anyway. Solar cells are also diodes. The primary difference between the rectenna and the solar cell is that the rectennna is tuned to a specific frequency. However x-rays will ionize atoms and produce energetic electrons just fine, without any resonance effect. In short, all you need is the equivalent of a solar cell. This concept is already embodied in the beta-voltaic battery(http://en.wikipedia.org/wiki/Betavoltaics). >For thermoelectric conversion, I would estimate that Nantenna technology >would be a good first step in converting x-rays to DC power. > >http://en.wikipedia.org/wiki/Nantenna > >In the DGT reactor, there is a nickel foam support the is in the zone for >maximum x-ray production. > >This foam can support 1 to 2 nanometer nantenna structures imbedded in the >foam fibers that can receive this x-ray radiation and convert it to DC >current.
