I think sometimes people don't see what they don't want to see. Maths disproves your Multi-Lever Phenomenon, but you choose not to see the relationship between the mathematical and the physical.
..when we are looking for a unknown formular, first you need the imagination to find new concepts...
Agreed
then build and measure, then comes the maths, maths are helpful but only if you know all the factors!
Here I think you will find a lot of variation in the way people do things. For me, usually something like:
research (including math), pop test, design(includes math), build, measure, more math, disappointment("why didn't I see/understand that before").
ADD: Ralph, physics is described very well by mathematics. Ignoring the maths does not change the physics.
Fluid dynamics and gravity, although there is interaction, are two completely different things. Saying your wheel is powered by gravity, is different to saying your wheel is powered by the Bernoulli Effect.
Jims basic description of the maths of potential energy in a gravity field is probably the best I have seen it described. Thanks Jim.
Hi Kaine,
That is a good example!
My model against your maths, my latest video will shows transverse levers, which has no geometry advantage as the prior designs but still shows the potential for closed loop with a small energy take off, and all I did was make the lever shorter and heavier, I will now try the same with a lever system that has the geometry advantage.
While you are about it why not try the maths on the self opening air filled reservoirs in my above post, say it is on a wheel 4m OD with the 20 reservoirs transverse mounted at the outer rim that hold 5 litres of air each when open, that is about 0.4 of a bar water pressure differential , + 0.2 bar greater air pressure to self open the reservoirs , so it will take 0.7 bar to close the reservoirs one at a time, now see how much torque force is gained by the 10 open reservoirs, and how much torque is required to close one reservoir! The above will drive a generator which will drive a small compressor, pneumatic pistons close and latch the reservoirs, and to help the efficiency when the pistons air is dumped it fills open cups at the bottom of the wheel, also the reservoirs are shaped like hydrofoils and are moveable!
With much respect Trevor
Edit, I also have a mechanical option, the open reservoirs are the source of the leverage in both designs, one side full, and the other empty so to speak!
Edit, the mechanical option has a number of frame fixed wheels that compress the reservoirs closed at the top of the main wheel, thus all that one sided leverage to compress one reservoir about 10cm !
