tweak to http://www.youtube.com/watch?v=h41oenbUGsE to charge the battery 24/7 while providing HV to lightbulb.
It may prolong the battery life, slightly, but more likely it will simply burn it out. You see, you didn't do anything to increase the current, without which will not keep the system running indefinitely. 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. There's no such thing as an infinite loop in physics.
I understand that it is impossible to construct an infinite 100% perpetual machine since things wear out eventually and fall apart and need maintenance, but would like to construct a generator that is feasable during blackouts that that does not require fossil fuels, so that I would have a light to keep me occupied drawing and doing art without going insane in the dark and cant sleep because of my erratic sleep patterns from my PTSD... So what do you think needs to be added to improve current, and will a rectifier fix the issue of regulating the overheating issue ? Would it run for the night without issues until the blackout ends ?
is that dynamo thing and that alternator car parts ?
It is easy to modify a setup like the one pictured to provide light for a certain amount of time. Just remove the dynamo and alternator, and find a light that will run off the battery alone.
The pictured setup will light a bulb for a shorter time than a battery alone could, provided you can get a 24v bulb instead of 230v. You have to think about where your energy is coming from. Energy flows from the battery into the motor. Some energy is lost in the wires, and you will feel them getting hot. Some energy is lost in the windings of the motor, creating more heat, and further energy is lost to friction within the motor. So the amount of energy that goes from the motor into the alternator is less than what came out of the battery. The alternator also loses energy through friction and within the windings, like with the motor. So there is less energy coming out of the alternator than was coming out of the motor.
So the alternator provides less energy to the bulb than what was coming out of the battery. But now you want to plug the battery into the alternator (through a transformer), ostensibly to charge the battery. That means that some of the energy that came out of the battery will be going into the bulb, while some of it will be flowing into the battery. As you can see, this means there will be even less power available for the bulb, and also not enough energy to replenish what the battery lost.
Even if you removed the bulb, and only ran this system with the battery, dynamo, alternator and the transformer, all it would do is slowly wear the battery down, I think. What you have constructed is an interesting and very noisy heater.
Silly me, I thought it was a flux capacitor --
You can purchase a motorcycle battery trickle charger to keep the battery 'topped off" during non-use and forget the rest. A 12 volt DC automotive light bulb (or more than one), some sockets, and alligator clips and your ready to go. They will illuminate for quite awhile off a battery that size.
If you want to have lights during blackout, get at least four batteries and a power inverter connected to the house current and configured to activate when there is a blackout. If it's only to power lightbulbs it could last a couple of days before it drains out.
flux capacitor ? my search shows back to the future... then found this..
That sort of thing can get rather expensive. Seriously, all she is looking for is the technological equivalent of a flashlight (only much bigger). Ed's more on the mark I think.
Physeter is correct as well, putting in the generator and alternator does nothing, ultimately, except waste the energy that's stored in the battery.
Cesar Deicide's idea I kind of like, because i need something that keeps on charging the batteries...
Physeter , well if you see in the video, a 24v batter turns a 24v dynamo motor thing, which charges up the alternator by kinetic energy to turn on a 230 v bulb... without a transformer feed back to re-charge the battery , how long would this rig run ? So you say that energy is lost with friction, would adding a wheel with magnets to attract and repel each other to create extra momentum , adding to the kinetic energy that is feeding the alternator fix this issue ?
