About 1604 through 1613, Cornelius Drebbel built at least 20 perpetual motion clocks. They were of course not true perpetual motion, which is impossible... but operated due to varying air pressure in a room. The basic engine is demonstrated by the model in this movie, although I had to use a hair dryer set on low to more rapidly create a differential air pressure in the engine's sphere, because of the time limitation, and the threat of supreme boringness. In normal operation, the sphere will "rock" slowly, over a period of minutes or hours. For more information, see: http://www.santa-coloma.net/drebbel/drebbel.html

  • Thats impressive !!!!! ( NOT )

  • @BRYCYNS You must remember that at the time Drebbel made his experiments, around 1604-1612, the idea that any machine would move "on it's own" (which is what they believed it was doing) was extraordinary. He and his "perpetuums" were the toast of Europe, and he was invited to the Courts of kings. Ben Jonson mentioned his machine in his plays. Yes, today it would not be impressive... you are holding an iphone in your hand, can fly by jet anywhere, and have a heart bypass. But in 1604? Wow!

  • stupidity creates stupid inventions

  • @philip2go What is stupid about Drebbel's invention? It was the rage of Europe at the time, as it would run clock with no winding, and show the phases of the moon, day of the week, the month, and the zodiac. And far from "stupid", Drebbel also invented a permanent cochineal dye, which started an industry... he isolated oxygen before Priestly, and built the first known working submarine. He also invented the first compound lens microscope years before Galileo.

  • how many hairdryers will you need to make this work on a commercial scale?

  • @mugwamp4 Very clever. I have one: How many descriptions do you read before you understand a video?

  • Hi dude.. the only system which works on ambient tempreture is a long and wide spring made from metal. At night it shrinks and during the day because of heat expands so we will have one movement in 24 hours. but I don't think it is a practical or economical systen

  • Very neat apparatus! 

  • being rare as they were back in the 1600's, he must've pissed somene off really bad for using their hairdryer |:
