This is a clock that doesn’t use batteries, solar power, or even electric. What it does use is pretty shocking.
This odd clock has a white belt that is drenched in honey to attract the flies. The belt then traps the flies inside and as it slowly moves around it sends these stuck flies into a blade that scrapes them off into a microbial fuel cell on the bottom. It breaks down the flies and turns the organic material into electrical energy. It takes 8 flies to provide juice for the clock for twelve days.
It is still a concept item, and there are those who are for it and those who are against it.
Learn Something Fun: The first alarm clock was invented by the ancient Greeks around 250 BC, but it wasn’t until 1787 that a mechanical alarm clock was invented. It took until 1876 for the first mechanical alarm clock that could be set for a later time to be invented!
