The offshore compute node will produce a lot of waste heat that would be absorbed by water from the fresh water processing. This heat can be used to maintain a methane digester at thermopile optimum temperature. The methane that is generated can then be used to run backup generators or shipped to shore to power municipal busses. Carbon Dioxide generated by the digester and generators can be utilized in the pleasure greenhouse or as part of part four (not yet posted).

The carbon source for the digester is the municipalities’ waste water stream. After five days at thermopile temperatures, plant and animal pathogens are almost completely eliminated. The fluids from the digester can be released to the environment and the solids sold as a soil amendment. Or they can be used for better things. This turns a sink of a municipalities’ nutrients and chemicals into a production cycle.
