The Bessler Wheel, mystery solved.

I think it can be put in another way.   As Newton's third law states,  forces always happen in pairs in opposite directions.  For  every F  there has to be a      -F  in opposite direction.    So, when you consider work as F*S reulting from force F,   there has to be equal amount of work  -F*S in opposite direction resulting from the force -F.

Something performs work and something(s) receives the work performed.  Energy is conserved.

Hence when you lift a bucket of water,  you will be storing potential energy  m*g*h  in it.  But your muscles will be spending energy
-m*g*h   in opposite direction  to maintain potential energy in the lifted bucket.  So, you will feel tired.

With muscles it is more than that because of how they function.  In order to hold something up using your muscles, they must contract and that consumes power constantly whether or not useful work is done.

So,  if you find a method  to add mgh and -mgh    only in magnitude leaving  the direction then net work done will be  2mgh !!    (efficiency is 200%)

No, the energies sum, not their absolute values.  If you link two weights by a massless rope over a frictionless pulley, then the total energy in the system is the sum of the GPEs of the two buckets, and that is a constant value:  raising one identically lowers the other and vice-versa.  Elevators use this to avoid expending unnecessary energy lifting the elevator car itself.  That does not change the energy that must be added to make an elevator car full of people go up, or the energy returned taking an elevator car full of people down.

Just a thought!  Correct me if I am wrong.

That is not how it works. At least not one of my wheels. Here is how it works in a veg description.  One foot reaches the descending side wall of the wheel at 2:30 as the other foot starts to lift at 5:30 and the full action is finished and then repeats. This is the same wheel that nearly took off my thumb and broke the mechanism over 4 years ago but the new version is a lot better constructed. It is very personal why I haven't rebuilt it till now. You will have to read about that on Besslerwheel.com comunity buzz for I will not repeat it if I can help it.

P.S. Now that we gave gurangax a rest. LOL, Now lets get back on topic and maybe we might see at least a covered wheel self starting then stopped and reversed as claimed.

ABHammer the comment that I responded to conflated the fact that the way our muscles work we have to expend continuous power to contract them, with the concept of work which is the integral of F*ds.  If there is no movement by an object in the direction of the applied force, then there is no work performed.  One can exercise all day long by pushing against a wall.  As long as the wall doesn't move none of that pushing does any work on the wall.

LOL nice slide of hand/word, but I was only responding to what was highlighted in red.

I think you mean if you ever show such a thing.  Many, many have tried and none have succeeded.  In order to succeed you are going to have to find a way for something to weigh more on its way down than it does on its way up.  No one has yet found a way to make a mass smaller based on its position relative to other masses.

Which looked more like you where responding to this part of what I wrote.

I thank you for that. But when we show and have a Working Wheel. It will through a large kink in the word Work for it will be doing Work with only gravity.

Therefore I responded to what said.

"Slide of hand???" 

Gravity wheels don't work and never have for the reasons that I stated.  You are free to believe otherwise, but will find yourself short of any example that supports such a belief.

Roll on June 1st.............?


Perhaps June will be a good month for the planet,we have the Tinman sharing something special on June 15th and now mr.gurangax on June 1st


Very nice .....very nice indeed


thx
