Poop power!
A South Korean professor that specialises in urban and environmental engineering has recently come up with an ingenious creation that would make toilets not just eco-friendly, but could also turn your excrement into power. Say what?
The beevi toilet.
As reported by Reuters, Cho Jae-weon, a professor at the Ulsan National Institute of Science and Technology (UNIST) designed the BeeVi toilet which reduces the usage of water by using a vacuum pump to send faeces into an underground tank. Furthermore, the tank is filled with microorganisms that will break down the waste to methane which becomes a source of energy for building, powering a gas stove, hot water boiler and even solid oxide fuel cell.
So how efficient is this ‘poop’ power source? Well, an average person defecates about 500g of excrement a day which can be converted to 50 litres of methane gas. With 50 litres of methane, 0.5kWh of electricity can be generated which can be used to drive an electric car for about 1.2km.

Professor Cho Jae-weon asserted,
“If we think out of the box, faeces has precious value to make energy and manure. I have put this value into ecological circulation,”
Furthermore, Cho Jae-weon has also designed a unique way to promote the usage of the BeeVi toilet. He created a virtual currency or e-money called Ggool and for every person that used the toilet, they will earn 10 Ggool a day.
Ggool means honey in Korean which fits in with the theme of the toilet as the name BeeVi itself is a portmanteau of the words bee and vision.

The professor has since set up BeeVi toilets in the UNIST campus and for students who have earned Ggool by using the toilet, they can use the currency to by goods on campus. From coffee to books to instant cup noodles, students can just purchase them by scanning a QR code to pay with Ggool.
Awesome! What do you guys think of the BeeVi toilet? Would you think that it would be more widely implemented in the future? Share your thoughts with us in the comments.
