I came up with the idea behind the Dale Simpson Gravity Wheel (page 4-11) many years ago, and actually designed and tried to build my version of it. I
spent everything I had to have the parts machined professionally, but when I started assembling them, I found I had undersized one part by mistake.
When it went, the whole thing tore itself apart like a stack of dominoes falling,
while attempting to run. I still have the apparatus.
I was unable to afford a rebuild, but a few years later I did draw up (I am a professional draftsman as well as a trucker) plans for a rebuild on a
slightly superior design. I even included mathematical proof of operation by algebraically analyzing the forces in order to calculate torque on the
output shaft and used calculus to sum all of those individual forces together. It does require a flywheel to overcome 'dead zones' in the rotation,
but the total output was even higher theoretically than I had expected.
I managed to buy the bearings for that design, but could not afford the machining of the parts. Thus far I have not constructed the newest design, but
as I now have a self-contained personal machine shop at my disposal, I may do so in the near future. The reason I have not been more concerned was two
other calculations I had made: there is a very high probability that a large enough unit to generate electricity for a typical household would wear
itself out within a period of days, due to the lifespan of available commercial bearings; and there is a danger of it flying apart with explosive
force due to the high output and severe centrifugal forces acting on the components.
One difference: my design did not use springs. 'Nuff said.
The Dale Simpson Hinged-Plate System (page 4-14) will not work. There is no torque turning the system; rather a balance of weight alone on each side
of the belt. Therefore the moment distance is not applicable as calculated.
There may be ways to adjust the design to overcome this, but a vertical belt system will simply not work.
I am not sure about the other units described in section 4.
The biggest surprise I had was in section 1, the magnetic motors. There are some very good insights and very good designs there that appear to have a
high likelihood of operating as described. I am only recently able to do any experimentation on magnetic possibilities.
That's all I really have so far, still going through the book. This thread needed a bump though, and your question seemed like a good excuse to do
so.
