The 2.5 x 2.5 mm device has a max power output of approx 0.8 mW at 10
deg K differential. Assuming 1 Watt excess with a COP 5 yields 200 mW
input. Would need around 300 of the MPG-D615 devices with fitted finned
heat sinks to each device's COLD side to get good thermal transfer into
the air. Could be doable with 75 devices per finned heat sink assembly
per side of a square container. Optimal load resistance could be a
issue. Something to look at in the future.

If we have a large COP (10-100), I believe we can use thin film
thermogenerators (http://en.wikipedia.org/wiki/Thermoelectricity) such
as these http://www.micropelt.com/down/datasheet_mpg_d651_d751.pdf to
make a self sustain wet cell... We can put thousands of those around a
wet cell. They produce useful power with as little as 10 degrees
Celsius (see datasheet).
Cheers,
