This week we researched into possible designs of a bio-gas digester. There is a generic design for the digester itself but the variance of the systems are due to differences with how the gas is collected and stored.
In the following week, we will research into two possible designs for collecting the bio-gas produced. It will be either collecting the gas within a separate (water tank) gas tank collector or storing the gas within the inner tubes of a vehicles tyre. Both of these ideas highlight the issue of the pressure in regards to the gas which would be needed to transport and store the gas from the digester.
Next session, an initial design on paper will be concluded and also a power point produced to be shown to a representative of Engineers without borders
