Congrats to this company BioGas 2.0 for creating this free gas system for household use.

The problem with it being that outside temperature cant fall below 20° Celsius. So some parts in the world works fine, but most would only work for short time in summer. Also far cheaper and better cold protected if a simple hole in ground, one side on a slight slope so excess can run out as new stuff is put in. Food scraps work but cow manure is much better as long as acid and alkaline content are in right amounts. About 2 years ago was experimenting with small 30 liter drum.

They can use gas to heat up electric heater and use the electric heater to heat up the small room where the biogas is stored. - problem solved.

Lots of rural communities in the world with right weather conditions (Pakistan, India, china, Vietnam, Philippines.....) use Biogas/ Methane Gas to cook or run engine to generate electric. It is just a hole in the ground to store cow manure, with a air tight lit and a storage tank (plastic bag or like in the first video a tire lube) The waste (overflow from tank) is the best garden fertilizer in existence.
Any food waste or manure works but cow slur is by far the best.
Smart countries (lol) grow crops (corn, wheat...) and let methane gas from cow, pig, chicken... mature escape to atmosphere dump manure on field.

This is something proven for many years by millions all over the world
In short any shit works as long as it is not contaminated with soap, detergent, washing powder......

In the 1970 a French guy (Jean Pain) run his car on Biogas. He had a system of Biogas production in the middle and rotting material (wood, leafs...) around the tank to keep it warm. Rotting material produce heat end even can catch fire in right conditions. It must be covered by dirt to prevent frost.
Hot decomposition also needs a certain minimum temperature to work.
Hedgehogs, Deers..... sleep on rotting leaf in winter to have a warm bed, which nature provides.
