My final idea is a model of a cow's bum! This is the 1st initial sketch of it
The problem was cows emitting a lot of methane gas through flatulence. The solution...create a bag to fit over the cows bum to collect the gas which could then be supplied to gas companies. It's just a starter project so the design doesn't really take much consideration about the other things that come out of a cows bum....
Starting to make the structure
Making the bum took the longest!
Found a rubber glove, perfect for the udder
Managed to buy some cow print material to make it look a bit more realistic. The model is attached to a wooden platform with a hole near the top to let the air through to the rear end. Nearly finished!
