A Coffee Maker For Your Car? These Are The Weirdest Inventions From The Past

Gas Powered Rollerskates

I’m not going to say I wouldn’t try these out, because they actually look like fun. However, the entire point of rollerskates is to get out and exercise. Plus, having a tank full of gas strapped to your back while flying down the street on a pair of skates seems like a great way to — well — explode! I’m not even sure if this tech would be street-legal. Even hoverboards these days are banned in many locations.
