Generator idea.

[Maker]

Dropped 1m, it would have 1GW ? (Mxgxh?) of potential energy

FWIW, Watts are a measure of power, not energy, it would have an energy of 1GJ.

Brilliant stuff.

How is the ball going to generate any stable electricity? As it would be pot luck which orientation the magnetic field from the ball is in relation to the coil each time it falls and if the ball is spinning and at what speed it spins each time, one run might produce AC another DC, if anything. The ball would be affected by the electricity it generates as the magnetic field from the generated electricity would interact with the magnetic field of the ball, and since gravity is the weakest force (i.e. you can deify the entire gravitational force of the planet by picking an object up off the floor) and the electromotive force is one of the strongest the electromotive force would have the greater influence. Once the ball generates any electricity it would be forced to levitate in the coil, than as the coil electricity is used the coils field would dissipate and the ball would fall again.

The stability is a solveable engineering issue.
Rectifiers, capacitors, shape of weight/magnet.
What I wasn't seeing is that to force the "weight" into the bottom of the flooded tube, I would have to displace upwards the same weight of water - that's what I missed last night.

The issue wasn't the rum - I only drank, in total, 100ml. And most of that, AFTER the above post
It was 6 hours sleep in 96 hours.

Hello Waddy,

tidal energy is low intensity energy and stops twice a day, it's not an effective generator as the huge amounts of cash being wasted at Swansea for a small amount of power demonstrates. Maintenance is high as an extra drawback.

Mercifully the DECC berks haven't been conned into bankrolling it(yet); it makes Hinkley Point look like a bargain.
