This is a heat powered electrical generator, with no
moving parts. Because the temperature differential
between heat input and output are relatively low,
efficiency is low; however, this also means that low
temperature heat source (an inexpensively made solar
thermal collector, for example)
can power the device.
Water is heated in a boiler located at the lowest part of
the system, and the bubbles of steam push slugs of
water up a pipe, in the same manner that water in a
percolator is sent up the stem to the coffee grounds.
The gaseous and liquid water are separated, in a
gas/liquid separator. The steam goes to a condenser,
and the condensate is reunited with the water from the
The water from the phase separator and the steam
condenser pass through a Kelvin water dropper,
producing static electricity.
The water then drains from the charge collectors down
into the boiler.
The two droppers, charge inducing rings, and charge
collectors of the Kelvin water dropper, are in a pair of
gas tight electrically insulated tubes.
The electricity from the Kelvin water dropper is fed to
a maximum power point tracking circuit, which draws
power at just the right number of amps to maximize the
