it's cheap as chips!   another alternative is thin black piping like
that used
on roofs to solar heat pools.

You can collect heat from the sun very cheaply, but the peltier
devices
to get electricity from hot water would cost more than solar panels.

Or a transparent plastic cover over a shallow Lake would heat up in
only
a couple days.  Those bubble wrap pool covers are like steam baths in
summer!

Stirling Engines would only be say DELTA 30 DEGREES / 270 efficient.

My Evap Cooler Droplet Catching design was meant to get the COLD
Terminal
down an extra 10-20 degrees to double the efficiency of Solar Sterling
Stations.

Bit of a nightmare generator to build though.
