Hi,
I'm new here but have been researching biogas and digesters and using it to produce electricity.
What I have not found out is where small "biogas generators" are used. Some are less than 1 kw in power costing around $500
They are sold by many Chinese firms and some are sold in Africa but I can find nothing about their performance in the field.
They seem a much more sensible answer to Stirling engines which will always be expensive.
There have been long-term problems using biogas as a fuel. Have they been overcome?
