Title: One more buoyancy idea...
Post by: Gravitator on January 15, 2009, 06:59:47 AM
Hi all,

I got one more buoyancy based idea which is some kind of variation of brian334 machine. I'm quite sure I'm missing something... I'd like to know what?

Gravitor,
At my website http://bsandler.com there is a better version of this machine.
When you get to my website click on the tab at the top of the page marked GRAVITY MACHINE # 1

p.s. it will help if you print-out the drawings.

Hey Gravitator,

I think the flaw in your machine is that you have neglected the work that would need to be done expanding the air vessels underwater against the water pressure.  The weights on the left hand side  would have to be so heavy to do this that they machine wouldn't turn. 

It would probably work in a frictionless liquid with frictionless bearings etc., but it wouldn't generate energy.  It would just turn like a simple wheel until someone removed its kinetic energy, then it would stop and not start again.  Its also very similar to the machine on Simaneks page at http://www.lhup.edu/~dsimanek/museum/themes/buoyant.htm.
