Foucault Pendulum
There is also another thread that I just started.
You blew your credibility by jazzing up the thread with "corioli effect." Bret Cahill |

That would be a good point, but of course, those who have failed to appreciate your insights feel the framework they work with is quite suitable to productive work - and their ability to calculate the paths of space probes and so on seems to confirm them in that belief.

Consider a pendulum suspended above the north pole with a swing that is aligned to the star field. Now stop the earth from rotating. Does doing that change the swing on the pendulum? Now re-start the earth and start extracting energy from the once-per-24-hours apparent motion. Soon you will run out of the kinetic energy contained in the inertial mass of the pendulum and it will have a swing aligned with the earth. Replace the pendulum with a gyroscope and the same argument applies. You can only get back the energy you used to start the pendulum swinging or the gyroscope spinning. -- Guy Macon http://www.guymacon.com/ |

Butttt! There is a perpetual motion machine. Its called taxing the poor.

Many people build what the think or claim are perpetual motion machines. Some of the builders fool themselves... but most just try to fool others for glory or profit. Mother nature cannot be fooled... It doesn't take that much education to understand why. Dear Sam: I agree 100%! (That's so rare for us!) If by "Coriolis" you refer to the forces that cause storms to rotate differently in the N. and the S. hemisphere, any energy advantage results from SOLAR energy differentials which cause the winds (or the water draining from a bathtub) to rotate in the first place. So this could never be a perpetual motion machine, because it has outside energy input. When I was in grammar school, one of my first "attempts" at doing science was to design what I thought was a perpetual motion machine. I hadn't heard of a thing called... friction, however. An uncle explained that friction would kill my idea. That "prize" is going to be safe for a long, long time! -- NoEinstein -- |

Foucault Pendulum
You have to apply or extract the torque in a way that wouldn't change
the magnitude of the angular momentum of the system. During most of the swing a Foucault Pendulum has some angular momentum just like a gyro. The gyro idea is nonsense from a practical point of view. 1 rev/day torque would be in the billions of N-m for even a few kilowatts not to mention the frictional losses from such a huge disks spinning in air or maintaining a vacuum. I brought up the Foucault Pendulum because it's the only idea I could think of sillier than a gyro. Bret Cahill The Foucault pendulum would do the same thing. No it wouldn't. A Foucault pendulum does not extract any energy from the earth's rotation. To understand why, imagine one at one of the poles. Now imagine stopping the earth's rotation.

Who provides funding? Anyone you can convince it's a good idea. Exactly. �If it were a good idea, The torque of a 1 rev/day 1 hp power plant would be: 1 rev/ 6.28 rad X 1 day/revolution X 24hrs/day X 3600sec/hr x 550 ft- lbs/sec = 8 million ft lbs. a little sketch would attract funding. Calling it the "corioli effect" destroyed his credibility. Bret Cahill |
