Update: On the electrical side of this invention (the Bedini circuit) I've located the wire gauges that we need to build the bifilar coil. Your local Radio Shack has a package that contains 3 spools of wire of the following gauges: 1)#23, 2)#26 and 3)#30. This is an enamel coated magnet wire, sku #278-1345. Although the design specs call for a #22 gauge wire the Radio Shack packet has #23 gauge and should not affect the circuit's performance any.
The pressing problem at hand is to find a mechanical method to wind the bifilar coil with 850 turns accurately. I've seen home-made spindle systems powered by a drill on the Internet that seem easy enough to rig up. And so, that is probably the method I'll use to wind my bifilar coil. When I get to that stage there will be more info on that procedure.
For today's blog I will discuss momentum and why it is important in the Bedini circuit. The Bedini circuit is all over YouTube these days. On the mechanical side it is usually a bike wheel laced with magnets around its circumference. Once you start the bike wheel spinning the electrical side of the circuit kicks in to energize and de-energize the bifilar coil which mechanically creates a repulsive action to the magnets on the wheel as well as voltage and amps on the electrical side. This repulsive action of the magnets and coil should keep the wheel spinning until forces stop it, i.e. your hand, inherent friction, etc. So, the mechanical problem we first face is to design a magnet rotor system that is not influence by any friction, in other words, a frictionless rotor system.
The problem is that friction is always presence in the real world. The best we can do is to reduce friction by an appreciable amount. That is why many of the Bedini circuits you see on the Internet uses the 10-speed bike wheel because the wheel's bearing system is very fine and reduces friction considerably. However, the wheel is just too large for practical uses in providing electricity for our applications around the house. So, a rotor design that is much smaller than the bike wheel needs to be employed here. A smaller wheel means a faster rotation which will help us on the electrical side to get the hertz (Hz) that we will need.
While a frictionless rotor would be the ideal situation; in real life the best we can do is reduce the friction as much as possible so that it doesn't erode our momentum over time. A good bearing system will help with that considerably. However, I think another mechanical concept here is important in achieving perpetual motion -
momentum.
Momentum is defined in mathematical terms as momentum = p= mass x velocity. That is to say p = mv. If we can get the momentum of the rotor large enough that might just overcome our inherent forces of friction with the aid of replusion of like charges provided by the coil and magnets. So, the variable that we can change on our rotor design is its weight; the more weight the better. Remember, weight (mass) at a certain velocity equals
momentum.
Because the prototype that I'm building is using parts that I have around the house my bearing system is not the best in the world (see above picture). My bearing system is a garage door wheel and bearing. I have a lot of play in the wheel bearing's axial which is going to cause me to loose some momentum due to friction. I want know if I can overcome this friction until I get the entire system built.
My design will be a dangling system with the rotor spin in a horizontal direction rather than vertical direction. That is to say that the garage door wheel will be suspended in some kind of holder and the axle part of the wheel will be dangling. Hopefully, the spin of the rotor will keep the axle on center rather than off center in its rotation - we'll see. With this design I'm loosing the positive effects of gravity (kinetic energy) as the magnets fall downward towards the coil. However, there is also a negative gravity effect as the magnets go up from the coil that my design will not have to contend with.
Again, the key to the mechanical side of the Bedini circuit is a frictionless rotation. Since frictionless rotation is not totally achievable in the real world I think that momentum will overcome much of the friction issue or at least balance it out so that the repulsion of the coil and magnets will keep it spinning. Stay tuned to more Bedini Energy.
