An Over-Unity Device - an Electromagnet Powered Beam Engine.

First we need a base and a beam. These can be any size, the ones shown are a base 500mm long by 140mm wide and 50mm high. The beam is 457mm long by 32mm by 20mm - 'cos that's what I had at the time I was building... The uprights, to be shown, are 100mm wide and blah de blah de blah... The device is petty much parametric so one can use their own dimensions from here on... Evidently I've fitted a bearing into the beam in mine, and the cut-outs in the base are 30mm wide.

Now make the beam ready for pivoting between two uprights.

This forms a basic beam engine. The beam will rock back and forth.

Next set a limit to the rocking, Here I think I used 7 degrees each way, 14' in total for a full lift. The towers are 30mm square with some dowel used to set the height.

We can then attach the lower electromagnet and its mount to each side of the beam.

And the (beam) electromagnets too. Along with two brass 'contacts' one on each side and each end of the beam. The ones here are brass strip folded.

In this model two rechargeable 9volt batteries are used to power the electromagnets.

Now the batteries and the electromagnets can be wired up, 2 separate circuits from 2 separate batteries, wired through a contact break at each end of the beam here. The outcome is that two separate circuits are formed which can only be activated once the break in its circuit is bridged.

The wires will be trailing.

A 'cake' bearing is fitted to the top centre of the beam to carry a top plate and weighted arm.

The top plate and the weighted arm are used to bridge the break in the electromagnet circuit/s. Beneath the end of the arm is a piece of brass designed to act as the bridge. This only happens for a set period of time as the top plate is revolved. The top plate is revolved using a rocking motion as with any (weighted) wheel when tilted horizontally. If rocked at the correct moment the top plate will accelerate. This is because the weight, given to the device, is past the nadir of the incline when repositioned by the activated electromagnets.

The top plate is now fitted with a gear system, I've used a pegged gear set, with two adjacent pinion gear wheels, so it is easy to see the concept. These will turn all the time that the top plate is turning and also be governed by the top plate's speed.

The pinion wheels may be fixed to generators. These generator can replace he battery power required to initially start the device up. Remember that it may be possible to accelerate the weight up to its terminal velocity, giving the top plate high speed rotation capabilities.

The whole concept is riddled with variations and re-design elements. The size of the generator is fairly optional.

As for the drive system, as long as the electromagnets can lift the given weight, the fact it is offset leaves it no choice but to revolve. (As long as its speed is sufficient to 'fly' the arm across the first quarter of its rotation, when the electromagnet/s disconnect.)

At high speed the beam will only 'wobble' as there will be no time for it to settle, but the same remains, an intermittent electromagnet activation cannot out-weight a constant turning of the generators. I see no reason why this device will not kept rotating and generating electricity until a wheel falls off!
