Week 8 Update

We have come up with a design that will allow the Ban Huay Mii villagers to create their own activated carbon which can be used to filter their water supplies.The design is as follows:

Over a fire place built from clay bricks a steel oil drum container will be held by 2 pairs of 2 steel pipes. The container will be filled with Nitrogen gas to ensure minimal Oxygen levels.A device (i.e.a handle) will be installed on one side of the container allowing the container to be rotated around its axis. On the other side of the oil drum there will be a pressure valve for safety reasons.
