Shit, whether it smells or not, has its value. British inventor Brian Harper spent three years modifying a commercial biodecomposition instrument, using dog excrement as fuel, and developed a "shield-generating street lamp" "
In fact, humans have been using animal dung as fuel since the Neolithic Age; they have known how to obtain flammable gases from decaying organic matter since the 17th century.
Dog owners only need to put the paper bag containing dog poop into the collection bucket under the poop circuit invented by Harper, and turn the handle next to it 5 to 6 times. The mechanism of the poop street lamp will squeeze the paper bag and let the dog poop enter the biodegrader. . After dog poop is decomposed by microorganisms, methane is produced, which is collected and stored to power circuit lights at dusk.
In other countries, similar types of devices have appeared one after another. Like a dog park in Cambridge, Massachusetts, USA, there is a biogas digester. As long as the dog's feces is thrown into the biogas digester, methane can be produced, which can eventually be used as energy for street lights, food trucks and popcorn exploding equipment. Supply energy.
Hong Kong’s solar power grid is starting to become popular. I wonder when there will be a bullshit power grid again.
