(Empowering): This backpack is filled with biogas from the biogas plant by simple pressure equalization instead of by pump or compressor. Therefore, it does not need to be equipped with a security valve to release gas in the case of over pressure. The Biogas Backpack is a pillow shaped balloon from flexible, gas tight material, plastic sheet and fabric. The two inner layers are made of gas tight PE-sheet, welded at the two open ends and equipped with a welded, threaded flange, holding a mini ball valve.

Biogas Backpack is gonna change the world

To use the Biogas Backpack efficiently, it would make sense to produce the biogas in one central, technically advanced biogas plant. This way, farmers in the surrounding areas could contribute to the biogas production by selling substrate to the plant owner in exchange for biogas and fertilizer.

To avoid accidents with leaking gas, the backpack is designed to be stored outside the house. Because of the limited amount of biogas, the high content (30-60%) of non-flammable CO² in biogas and the non-pressurized status of the gas, there is no risk of an explosion. Even if in contact with open fire, the backpack does not explode, but rather burns down in a controlled manner.
