And so, perhaps realisation dawns... We now have a simple torque amplifier, as opposed to 'free energy...' Erich, do you have a sadistic streak within you? I ask simply because you have been a consistent exponent of conventional physics within the context of this thread, and now it would appear that you are encouraging an impossible dream through non explicit recommendations, with concurrent financial implications for the poster. Why would you do that? And to quote yourself; "Well, here we are in 2015. As we enter this new year the laws of thermodynamics and Newtonian mechanics are all still in force and the perpetual motion machine is still an unrealizable dream of many." If you are a professional in your field, then I seriously think that you should reconsider your engagement with Paul T. Yes, it's good to have a bit of fun, but not at the expense of someone who seeks sincere advice for a fruitless cause that will cost them more money.
