Slow self start

Adding pulse motor and down sizing test fixture.

Hi, I completed the fabrication of the new test pulse fixture.
The pulse motor is triggered every 180 degrees, with a 20 pound flywheel and at 18 volt trigger max RPM is about 150. Added first gravity assisted component and RPM's drops to about 50. I will continue to test different variations. Searching for configuration to increase RPM's without increasing the input voltage. Suggestions welcome.

Pulse motor is driving a PMA and I will be adding a MPPT circuit to reduce the Lenz effect.

I like the twist you have added :)

Low-Q,, you do understand that by LAW a closed system is 100% efficient and that anything that is not 100% efficient is NOT closed,, right??  Another thing is, why keep on how far in the vertical plane the weights move?? it is not how far they move in the vertical plane it is in the path they take while they are moving.
I don't understand that, because it's not really true. Nothing is 100% efficient. I mean, energy does not disappear, but not all energy spent is useful to what purpose we need it for at the end.


If we are fighting against gravity, all that counts is the potential energy any given weight has at any given hight (Or altitude if you prefer).
The path isn't important. You can move an object around the globe and slightly increasing altitude by one meter after 40 000 km travel. The potential energy added to that object depends on its weight and that one meter.

And of course if the weight is then lowered in another part of the cycle, then the GPE gain gets surrendered.  All these contraptions that go round and round without performing useful external work are ornaments.
