Summary

Description
English: Hand-drawn schematic of a DIY anaerobic digester, designed by Dick and James Strawbridge.
  • 1: organic waste inlet (placed below the surface of the decomposing waste to avoid letting in air to the tank)
  • 2: digested waste outlet (can be used as organic fertiliser)
  • 3: biogas outlet
  • 4: biogas bubbles trough water, into the floating gas storage tank
  • 5: biogas goes up towards the flash arrestor
  • 6: biogas goes towards the internal combustion engine for use

A: paddle (manually or electrically operated) B: radiator (distributes heat of solar thermal collector system; part of solar thermal collector system) C: 2 radiators, painted black, function as a solar thermal collector; part of solar thermal collector system D: floating gas storage tank E: flash arrestor (also called a "bubbler"); this prevents the stored gas of accidentally igniting, due to heat from the internal combustion engine furtherup

Note that the DIY solar thermal collector system presented here can either operate using thermal siphoning, or a small pump can be used. To regulate the heating, a PCB with temperature meter, and electrically operatable valves can be used (in the case of thermal siphoning) or the pump can be electrically controllable by the PCB (in case a pump is used)[1]
