Wikipedia is always a good resource to explain the basics  http://en.wikipedia.org/wiki/Hydraulic_machine

Remember though that just like a common lever there are tradeoffs between force and travel. However, a combination of hydraulics and levers might work. The other advantage is that unlike a lever, you can move the force anywhere you like.

I'm new to this forum, hello to everybody.

Interesting topic. Has anybody been able to replicate Bob's work?

My opinion

Bob has had 9 prototypes, the latest design has moved to the utilization of hydraulics. My perception is that throughout all earlier attempts, energy produced has not been adequate to support the feasibility of the project... With this in mind, herewith a perception of major components included in the latest prototype.
(I hope that Bob’s design and energy generation is significantly greater than operation consumption.)

Hi All,

       Anyone heard any news of Bob's progress with investors and prototype testing?  I know that the middle of November he was gearing up for a private disclosure to interested parties.

Hello All,

There will be an update coming soon.

@ Yas,

You must be a young-un!  vacuum assist brakes have been around for 15 to 20 years before 1970. Almost as long ago as fur lined bathtubs to keep the water warm.

Before getting to excited about hydraulics I suggest a little background learning in 'Fluid Hammer' Viscosity, and Bernoulli Fluid Dynamics. For a reciprocating application it is not as simple as it looks.

As for the unknown hose in the above picture, I  would bet it is the exhaust or return line. On the other hand that which is identified as the supply is laying over that which is meant to turn?  As for the valving, we already know he uses or used electric solenoid operated valves. You can see the commutator and contacts in one of the pictures. I would suggest a 3 point version with a common closed neutral position.

For the present, I agree with Jon, give him a little more time or go ahead and build on the premise that you have it figured out. Take my word for it, if it's a winner, we should know shortly. Then again there is already justification for the conspiracy minded to believe the MIB  are already present. As for me I am already designing next years model!
