I invented the perpetual motion machine, which can continuously do external work without any energy. ...

Take a break when you have time, and don't always do such useless things. Perpetual machine is a machine that does not consume energy and can do work forever, which violates the law of conservation of energy.

Science is progressing, but the study of perpetual motion machine has never stopped. I don't know how many folk scientists in China and even the world, even experts, scholars and professors, have spent a lot of precious time, money and painstaking efforts to find such a non-existent thing, which makes people feel sad. Of course, there are also many liars with ulterior motives. Common methods include selling or transferring his "perpetual motion machine drawings" and "perpetual motion machine technology". In fact, as long as you have some basic physics knowledge, you can see through this deception.
