A thought about how one could use the temperature differential
between sunside and nightside on a spacecraft.

If an external sunside heat collector contained a volatile liquid
that could be superheated to pass into a turbine generator in the
bowels of the craft, and the output cooled by radiators on the
nightside, power could still be generated if the solar panels had to
be furled during a solar flare episode.

Or am I missing something here?
