Pyroelectric conversion in space

Pyroelectric conversion in space deserves a close look as preliminary calculations indicate that a system specific power of 350 to 850 watts per kilogram will be feasible. This power-to-weight ratio far exceeds state-of-the-art photovoltaic systems (40 to 66 watts/kg) and surpasses proposed thin blanket photovoltaics (about 300 watts/kg). In addition to its high specific power, the pyroelectric approach promises to be far less expensive than photovoltaics.
