How much horsepower was Bessler's largest wheel?

Hi Fletcher

Agreed it's best to use it as an external rating system.

We don't look into car engines to calculate power. We get them to do work.

Power estimates for Merseburg and Kassel wheels: http://www.orffyre.com/measurements.html

I've searched some old threads.

The Kassel wheel lifted a hundredweight. Some say that was 100 lbs, some say it was 112 lbs.

Down through the floor pulley, up to the window, over that pulley, down to the 'courtyard below' ; 30 feet maybe, assuming 15 foot ceilings in the castle to accommodate a 12 foot wheel.
The axle was about 7.4 inches diameter (1/3 ell).

23.2477" circumference axle (7.4 times PI) x 20 rpm = 464.954 inches per minute. Divide by 12 = 38.746 ft/minute. Divided by 60 = .6457 feet per second, about 7.748 inches per second, fwiw.
A 30 foot lift would have taken about 30 / .6457 = 46.46 seconds (no block and tackle reduction).

HP = Force, times Velocity in feet per second, divided by 550. (Natural Forces and Bessler thread).
So using 100 pounds as the force we get 100 times .6457 / 550 = .1174 HP for the K wheel. 87.5 watts.
This could be higher if the rpm was 26, or the lift was greater in force (112 lbs). It would be less if it took longer with a block and tackle.
112 /.6457 / 550 = .13148 HP or 98 watts.
26 rpm: 112/.8395 /550 = .2425 HP or 180 watts.
4X block and tackle reduction : .6457 /4 = .1614 ft. / sec. or 1.936 inches per second. ( I think, if all you do is divide by 4).
This would have taken quite a while, about 3 minutes for the lift.
112 times .1614 / 550 = .0328 HP or 24.46 watts.
I think my math is right, I used diameter on another thread's estimate instead of radius in the formula.

Pretty bummed out that by all the many estimates of the power of Bessler's wheel, the power is pretty tiny.
Makes me feel it's not worth the time and effort to proceed.

Don't be frustrated ArchCalc. Bessler had to keep the weight down lest his wooden wheels fall apart. They could be scaled up, have more mechanisms added, and even be fabbed out of metal. Consider it an introductory rating that can only go up from there.

Besslers wheels were pretty weak.

Depending on the actual motive principle to it, there is a good possibility it can not only be scaled, but the principle may also applied differently, leading to multiplying the end power significantly.

ArchCalc,
The wheels were meant to show the feasibility of it, not there maximum HP. The 2d wheel was by far the most powerful. Under full load from the stamps, required tremendous effort to stop it. How much power would you approve of?

My contention has always been, that the last wheel incorporated an onboard gravity brake to keep it stationary, which reduced it's unloaded speed. Besides; it was designed to have low power, so that the prick scientist could stop it with just there hands.

It was a big problem; how do you stop it? Suppose it had developed 100 hp. I wish some one would explain to me how could you stop it---------------Sam

It begs the question why he didn't build a more powerful version as he said could be done. Using the most flattering estimate, .2425 HP, it would have taken 4 wheels to get 1 hp. Maybe that's why he didn't try, it would have been a huge wheel to construct.
The actual motive principle is probably the main reason it couldn't be scaled. The energy source was weak; ergo they were weak.

[JUBAT]

Don't forget it is scalable in the 3rd dimension so that a cylinder would be long but not as high. Bessler held himself back because he couldn't load more weights into his wheels without risking compromising the structure itself. Imagine having 100w constantly charging 24/7. Free energy is worth it no matter what form it takes. It tips the scales in your favour.

I will never understand why people have so fucking little regard for Bessler, his wheels or gravity-------------------Sam

[ArchCalc]

Reading your last posts here, I'm getting strong clairvoyance about the divisions in the AP wheel diagram. Something was occurring in thirds of the circumference.

If you want me off of here: just say so-------------------------Sam

Relax I see no laws broken by posted material.

I suspect it is the same reason the inventor of the electric motor didn't also invent a Model S Tesla.
