Ferrofluid

Tom...

I think the biggest problem with this design is not so much the viscosity of the ferrofluid, but whether or not the downward pressure on an emerging spherical float as it leaves the ferrofluid and enters the water will be greater than the total force due to flotation on the spheres above it in the water. In principle, one can always increase this total buoyant force by just increasing the height of water containing cylinder and the number of spherical floats in it at any time. But, of course, that will also increase the downward pressure that tends to prevent a spherical float emerging from the ferrofluid.

Which of the two opposing forces will win? Or will they be equal? Unfortunately, this is not the type of design that I can readily test with WM2D. I leave it to the hands-on hydraulic perpetual motion device builder to tinker with.

Since as i mentioned before, ferrofluid is expensive, but kens design looks like it might work! and Tom, mabe it's just my bbrowser, but i open up the website you provided. Here's a short little guide to make ferofluid yourself.

i don't know the quality of this ferrofluid (probably not to good) because i have no clue where u are supose to get cheap toner!
