In practical terms, I put in about 2kg of food waste each day and so far I have had enough gas to cook with, sometimes twice a day. If I ever needed more gas, I could put in more organic matter. I will continue to monitor the system as part of my research and will publish updates in due course. If interested, watch this space.

I have a functioning biogas plant at home. It functions as a spetic tank and also takes biowaste from the kitchen. Turn around time is 30-60 days and it gives about 45-60 minutes of cooking per day on our two person household.

I've also read that because the bioreactor is hot from the bacteria, people in colder countries can run water through insulated tubing to get 20C water.

That sounds great! I hadn't even considered capturing human waste. Do you rely on that entirely? or are you hooked into the mains?

We have an induction based stove that is used 50% of the time since we have solar.
