Hay BioGas and Kite Hybrid Progress
Biogas is not glamorous, but has vital roles
in both climate science (as GHG and ODS, if disregarded) and energy
production (in a sustainable carbon-neutral cycle). Starting in 1958,
cesspool gas was tapped for cooking in the PRC. Since then generating
power with landfill-gas has become a standard civil-engineering practice.
Flash forward- KiteLab Austin now has a working Hay Farm as an AWES test
site (with an anchor-field installed) Last year we validated dual-use
(kite-hay) compatibility. Kites, switchgrass, biogas, and biochar have all
been discussed on the Forum before. Now is the time to to actually test
another round of these ideas, at small scale.
While biogas is diffusely sourced and rather limited in quantity, it looks
like an ideal storage medium to supply continuous baseload power from
working Hay and Kite Farms. There are numerous natural-gas and biogas
compatible engine-generator sets on the market. Its quite possible to
adapt these units, or make one's own version, to accept kite power to make
electricity when the wind blows, but burn biogas when the wind is calm. We
can set up a small experimental plant without too much fuss.
A supply of hay can be kept on the farm as non-explosive fuel storage
(explosive biogas is best used directly). The main hybrid-design job is to
automate the mechanical clutching between kite and combustion engine, and
managing the gasification cycle. Hay bales act as "stove pellets",
entering an enclosed preheat oven, and gassing off the fuel for
combustion. The left-over biochar is a superb carbon sink and soil
Peat Farms and other natural crops (non-irrigated, no fertilizers or
pesticides needed) may have a similar sustainable cycles as net
carbon-sinking biogas-kite power hybrids.

Cautionary Tale- Ten years ago many of us in Austin experimented with
DIY veggie-oil diesel, which was kinda cool, but not ideal. At one
point a massive DIY biofuel production plant fell out of the back of
one of our nomadic circus buses onto the highway, along with barrels
of finished fuel and methanol. By great luck, no one was hurt. (I
warned them, *sigh*.). ds, 28Feb2013
