huh ? dang how old do i have to be to get some RESPECT around HERE 100 year old ???
The quest for such a perpetuum mobile is actually quest for constant difference. The work done that you want to get for free should be made proportional with some other difference that remains the same all the time. The work done is difference in energy.Originally posted by Jimmy
I'm speaking in regards to the extraction of free energy by using so called perpetual motion machines. Sure, you can say we are all in perpetual motion but that's not really what we are talking about, is it? Were talking about free energy. So I should have made my question more precise. How can one make a perptual motion machine and extract free energy from it. I say it can't be done. No such thing as energy out of nothing.
Perpetual motion implies a self-powering process, not just physical motion. Newton's first law is not perpetual motion.Originally posted by ray b
is an electron in orbit perpetual motion??
what about a photon will it travel forever unless it hits something
