In the first summer of our project, we began to experiment with different materials in order to create the most effective system. We faced challenges finding the right gas nozzles and adjusting methane levels, but our determination grew as we learned and improved each day, leading to the creation of our first biofuel gastank prototype.
Gas nozzle and tubing used to seal and transfer the biogas for usage.
Completed biogas tank with filled with 1/3 manure mixture.
Mixture of 1/2 fresh manure and 1/2 water used to create biogas.
This is our initial nozzle design we came up with. On the far right is the gas nozzle which controls the gas flow. In the middle is the biofuel tank cap which we drilled a hole into for gas flow. To the left is nozzle fastener which screws the nozzle onto the cap. Rubber seals are also used to avoid gas leakage.
