Tri-gate energy gain

[1BustedMyth]

Very simple test

[eckyspondoolie]

set the magnets in the same curve as the swinging pendulum (not flat on the table) and it may go higher?

[foxtrotyankeeindia]

Does it reach a height above that which it is reaeased from? If there was a g or f force acting on it on the way up, it would also be also acting on it on the way down. Consider a 100g weight on a spring released vertically, it would not reach a height above that frm which it was released - unless wrk was applied to it (vertically). Disregard the acc and decc forces of friction and gravity (they are cancelling and applied equally and oppositely in each vector of harmonic motion).

This video illustrates a concept that argues for perpetual motion against the typical "but the conservation of energy says.." response. You see, the pendulum has gained energy from the magnets, correct? because it got farther. Yet the magnets retain the same power, the same energy. it has not been transferred "out" of them. so energy has been created. If you are clever, I think you could possibly create a system that uses this slight gain to stay in motion, as long as the

energy the magnets give is greater than the energy consumed in rotating/moving/etc. the magnets to position them in a way that they can give their energy again, and again, and again..

(and the movement of the magnets of course is necessary to keep the opposite end of their polarity from interefering with the movement)

@EverythingInane The pendulum has not gained energy from the magnets, it has gained energy from the hand that had to do more work to put the pendulum in a position of higher magnetic potential energy.

You're ignoring magnetic potential energy, which is exactly as silly as ignoring gravitational potential energy. It's like saying a pebble gains kinetic energy when it falls, if I can just cleverly harness repeated falling(ignoring the work you have to do lifting the pebble) I have free energy.

Tri gates don't = free energy. All you are doing is making a magnetic spring. The force that you apply pushing the roller to the gate is like compressing a spring. Once you get it past the gate it shoots to the other end. Just like releasing a compressed spring. It will travel some distance but it will eventually loose the compressed energy and not have enough force to continue. Thats why it doesnt work when you line up 10 or 20 gates. The energy that you put buy pushing it to the gate runs out.

This is a clever little experiment.

[foxacoustics]

Just a guess but if it swung higher with the magnets its probably becase the magnets were pushing up on the swinging arm reducing friction.

The magnets should not assist it in swinging any more because you had a solid magnet on the end of the are and you were not reversing the magnetic field on the arm as is swung back and forth.

[Nickondeweb]

even on a horisontal axis. Or with a counter weight as friction reducer?

[wopwops0482]

do you have any plans to try a rotor?

[frenkystromar]

No, because friction loss is bigger than energy gain.

[wopwops0482]

interesting!
