The new builder, has begun from bottom, a litle smaller, he have a smaller garage :-)
I am thinking of looking him up this weekend to look at his progress !
: Oh,, I understand what you mean, but demo model is just one arm/weight, because it is the only thing I could make propperly in my garage. The big wheel thing got out of hand sort of speaking. I did never got to finish it, I am no mechanic at all.
: The demo goes up and it returns down, transfering weight different up and down. But comparised to a revolution it is maybe
: just 30 degrees of a revolution and just one arm.
: Then I did not have to balance the whole thing etc...
: Rubberwheel is just because they attach better on a surface and they can absorb som force if sped up and landing on something etc.. With a rubberwheel I meant like a very tiny bikecyclewheel !
: : Hmmm sounds intriguing...but why rubber wheels - is there to be some bouncing involved? The other thing i meant to ask before was re your demo model. If you're getting twice the output from input, shouldn't that be enough to turn?
: : regards, Andrew
: : : Friction is not a question here, only if the construction is very tiny, and the weights are light.
: : : Ex : 1kg weights and 1 meter base arm. with 8 arms/weights this construction, will have about 1 kg overweight/unbalance * arm (1m)
: : : This gives you the possebilety of alot of friction in the center.
: : : There will also be friction one more place, this is the more trickyer part. Not so tricky today, Well beared rubber wheels, with som size. This will support the weight pretty well, and mekes friction no problem.
: : : : Well, best of luck with the construction - it's good to see that you are actually building and not just theorising like so many others. But tell me Oystein - will you have much friction to overcome? Clearly you are moving your weights around with respect to one another...won't this lead to some frictional losses?

: : : : : It will be very soon !
: : : : : I have already made an demonstrator using the principle !
: : : : : It does not rotate, but it gives you almost double Work(M*A*D)
: : : : : back, than you put in.
: : : : : read my new WEB-site www.mamut.com/cfconverter
: : : : : The mechanican that I "hired" was willing to do the wheel for free, but he moved to scotland because of his job.
: : : : : I have let an very eager retired handcraftsman do the job.
: : : : : He could see that i would work, and refused to be payed.
: : : : : This is just 1 and a half week ago !
: : : : : I have spend all my time, with physics and math, to prove the principle, and have come up with exactly the same as measured in practical tests. It is actually possible to spend less work lifting a weight same distance, also theoretical !!
: : : : : I think it is just only this one configuration that alowes this. It is super simple, but it
