From another board.
All this talk about flywheels has made me wonder. How many members
remember shaving flywheels on their hot rods in the fifties.
Ok a littl about flywheels. they are meant to maintain a smooth
momentum. but "What if" I want quick response in gain or loss of
RPM. You go for light weight and low inertia. this is what you want
in your hot rod so that you can get max acceleration and RPM off the
line for that quarter mile run. you do not care how the time it
takes to run down or maintain tourque.
Quite a diffrent story for the flywheels used on steam engines to
pump water out of mines in Nevada during the mining hayday. What
does it take to lift water over 1,000 feet with a single cylinder
engine, a BIG flywheel. History has documented some of these wheels
at ove 40' in diameter and weighing tons. Now once you get it
spinning with no load I do not think your going to stop it with your
foot or in a couple of seconds.
Another mode of mechanical power that uses this concept is a train.
you have a lot of weight made up of say 90 rail cars. but only a
couple of diesel electric engines to move it. Ever wonder how a
dispatcher figures out how many engines will be needed to move it
over hill and dale. I have been told that it is something like 1/4
horsepower per ton of rolling weight
Now back to Bessler. My hat is off to the boys who have kept this
thread going in a true exchange of ideas and input without any
blazing. It makes it well worth following and leaves one in a great
frame of mind for putting on the thinking cap.
I know that thousands of people have attemted as many aproaches to
duplicate the alledged workings of the Bessler wheel. It is groups
such as this that keep that ball rolling and more Ideas to try. I am
no different, I have two new ideas born from this thread and am
wondering why is the pendulum on the outside of the wheel and not
inside. Could not the pendulum move the weights from outer radius to
inner on the upside of wheel radius. I do not believe we give the
pendulum true recognition for its atributes to static and kinetic
energy at the same time. Like the fly wheel once you get it swinging
it does not stop on a dime. I am not a math person so will ask some
one else figure this out. A pendulum with a 10' solid rod lever with
an attached weight of 20 lbs, installed in a 12' Bessler wheel . How
much torque in foot pounds will be developed at center axle with
weight raised to 45 degrees from horizontal. when releasing this
pendulum how much weight with low friction could be moved in a
horizontal plane on a greased rail from one side of our wheel to the
other. I am going to guess that it would be in the hundreds of
pounds. Now we have to ask how do we keep the pendulum charged. How
about a bellcrank attached to the wheel axle and to the pendulum arm
aprox. 1/4 the distance from pivot point to weight.
Think of a child in a swing, a little pump each cycle and he keeps
getting higher and higher. Ever stop to think that in physics he is
actualy lifting his own body weight with each little pump and it
keeps compounding. The swing stores the energy and uses very little
to maintain the cycle of repetitive input. Now replace the chain or
rope on the swing with a siff rod and you have a pundulum or lever.
And as the saying goes give me one long enough and a place to stand
and I will lift the world.
Input please,
