If you were having a shitty day, imagine how this "bio bus" driver must feel...
According to IFLS, the UK just sent the first human poop-powered bus out to shuttle passengers around town:
"This “Bio-bus” runs on biomethane gas, which is produced from the treatment of human sewage and food that is unsuitable for human consumption. It has a combustion engine that is similar to diesel engines in normal buses, but the gas is stored in dome-like tanks on the roof.
The gas is generated using anaerobic (oxygen hating) bacteria, which break down the waste into methane-rich gas. Before it can be used to power buses, CO2 is removed and propane is added. Other impurities are also removed so that the emissions are virtually odorless (thank goodness). It also produces fewer overall emissions than traditional diesel engines, and is obviously more sustainable... The bus clearly shows that human poo and our waste food are valuable resources.
Just one person’s annual food and sewage waste is enough to fuel the bus for 60 kilometers(37 miles). One tank is sufficient for a 300 kilometer (186 mile) journey, which is about five people’s annual waste."
This gives whole new meaning to gas prices.
