tweak to http://www.youtube.com/watch?v=h41oenbUGsE to charge the battery 24/7 while providing HV to lightbulb.
Adding a wheel with magnets would increase the friction and amount of energy lost. Because you have stationary magnets, there would be a time in each revolution that the magnets were helping (i.e. pulling the wheel along) and also time they were hindering, i.e. trying to drag the wheel back the wrong way. Spinning magnets creates a moving magnetic field, and that uses up some of your energy.
Energy is lost to friction AND to electrical resistance in the wires, don't forget. The wires connecting one to the other will get warm, and the wires within the motor and alternator will both get warm. Heat is energy, so when wires get warm, you know you are losing some energy.
argh.... thanks well I have to get parts then and work on it and try work on these annoying factors.
so device may need a solar panel.... but it isnt going to work well in winter with daylight time from 9am to 3pm... so turning parts have to be made that they turn smooth to lesson friction, and magnets need to be small and powerfull.
well at least it might keep me warm if they throw in as gas blackouyt as well as an electric blackout..
After a hurricane devastated my town, I used a boat battery to run an dc to ac inverter to power a lamp and a small TV/radio and a fan. I charged the battery as I drove to work when my company reopened. Did not have electricity for 5 weeks, but I did have plenty of gasoline in my boat's 40 gallon tank. I have gone through three major (cat 4-5) hurricanes here in Florida, one took my apartment's roof away.
You'd do just as well to run your light off the battery and forget the "perpetual motion" garbage.
H3xx said, "The problem with perpetual motion machines is that they either produce more energy than they consume, causing them over heat and explode,....."
If a machine produced more energy than it consumed then it would truly be a perpetual motion machine.
@H3xx - The problem with perpetual motion machines is that they either produce more energy than they consume, causing them over heat and explode, or they consume more energy than they produce, causing them to fizzle out and crawl to a halt
And then machines are constructed of parts that simply wear out eventually.
Do you hear, when you plug in the light bulb, the mechanism starts slowing down slightly. It's even more noticeable when you unplug the light bulb - it runs faster. The difference in RPM represents the power lost (mostly through the heat of the bulb but also through resistance of the wiring, friction, etc.) - power that leaves the battery minus the power that is returned to the battery.
Think of it this way: why not add in ten dynamo/alternator pairs? Then you'll generate enough power to heat your whole house. Seems to me the search for alternative energy sources is now obviated. Or maybe not.
Physeter has it exactly right - "an interesting and very noisy heater".
