GroundGen Reference Standard (GM Voltec Powertrain)
As hybrid electric vehicles continue to evolve and enter
low-cost high-volume production, we follow progress with an eye to
re-purposing components for COTS AWE. A hybrid car can be driven
on-location to power a remote village or health clinic, and just ten of
them amount to a megawatt rating.
GM's Voltec Powertrain is perhaps the best current reference model, with
flexible options for mechanical-to-electric output. For starters, it has
two motors/generators, large and small (a "pony"), allowing single or
combined operation over a wide range of conditions. The battery pack will
cover most dynamic-load and wind-supply fluctuations. The internal
combustion "range extender" engine can be a flex-fuel or biodiesel engine,
able to back up lack of wind for extended periods. At the heart of the
system is a planetary gear that mixes and converts the various power
sources and sinks. HarryV previously noted how planetary gears might be a
key to AWE.
