generating electricity?

Im am a novice at electics,  i think that a coil of wire through a magnetic field will generate a charge,  Yes/no?  if so would a number of coils passing through one magnetic field be more or less efficient than 1 coil passing through many magnetic feilds?

electricity generators

Alright, so I'm working on a project, which I won't disclose at this time, and I need as many different ways to generate electricity as possible.  Any and all ideas are welcome, nothing is too weird or unconventional.  The on requirements are it needs too be portable and smallish, in theory it should be easily carried on say, a hiking trip or something.  It also needs to be able, even with some circuitry, to charge a battery.  Ideally 2 AA batteries in series, but higher than 3v is OK as well.  So, I will compile all the ideas and, if they will work for my purposes, I will include it in my instructable I'm working on.  Any suggestions are greatly appreciated and all ideas are welcome.  Fire away!

Plant Electricity Generator?!

OK. this is gonna sound very crazy. i remember learning this thing about photosynthesis. there are electron acceptors and donors. during photosynthesis, the electrons are passed on and on. it's like redox reaction. or perhaps it is redox reaction. anyway i came up with a crazy idea of generating electricity from plants. there just might not be enough electrons to do the "work" (to get at least 5V? impossible.). batteries have the + and - terminal. plants have electron acceptors and donors. crazy, eh? what do y'all think?

So I have made two different versions of this spark generator, one used a Marx generator design and the other with a voltage multiple design. Both are working well, but when I expose a lighter fluid soaked wick to either one neither can start the fire. So the only thing I can think of is that while I am generating the spark it isn't hot enough or I am generating the spark before the vapors can achieve the correct oxygen/fuel mixture. Any ideas? Both use a modified Flyswatter circuit.

Frictionless generator for a bicycle? Answered

Will this electric generator idea work?

Will this work? A wheel that has neodymium magnets and coil of wire around iron, basically an electromagnetic. next to the wheel is a coil of wire that generates elctricity when the wheel turns, this coil conveys the electricity to the electromagnet through means of copper brushes. On the other side of the wheel is a coil of wire which gets electricity to power things. In my head, id say that the magnet powers the 1st coil then the 1st coil powers the electromagnet which also powers the 1st coil which powers the electromagnet even more. So in my theory, the electromagnetic gets infinitely powerful (till it burns out). So in a way the wheel can be cranked by hand and yet the 2nd coil will get a large amount of energy. Will this work in real life? why or why not? If this idea already exists what is the name?

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.

Thermoacoustic electric generation at high frequency? Answered

The goal: cheap, easy(ish) electricity. The power source: concentrated sunlight or fire. The question: Has anyone here made them self one of these? : a thermoacoustic electric generator which runs at high frequency. I'm not talking about a sterling engine at least not exactly. Rather I'm looking to make something that resonates much faster and could be harnessed with a voicecoil or a piezo electric transducer. This has been done by grad students and researchers but I haven't seen any built by the DIY crowd. There are some startups around who tout this method because it is more efficient than a sterling engine and easier to build because there are essentially no moving parts or sliding seals. The higher frequency seems to be the tipping point in efficiency because there is less gas moving but moving with the same energy: "Minimizing the flow velocity of the gas overcomes viscous losses inside the regenerator, whose tiny pores allow heat to move between gas and solid most efficiently." http://www.americanscientist.org/issues/feature/the-power-of-sound/5 I'm thinking of making something with common materials: a loop of steel pipe and speakers or a bunch of piezo buzzers and a bike tire valve to add compressed air (for higher frequency oscillation). Can anyone lend the voice of experience for us? Here's some reference material: http://www.wired.com/science/discoveries/news/2003/01/57063 http://en.wikipedia.org/wiki/Thermoacoustic_hot_air_engine In greater depth: http://www.americanscientist.org/issues/feature/the-power-of-sound/ http://www.aster-thermoacoustics.com/?page_id=141 Videos: http://science.discovery.com/videos/invention-nation-thermal-acoustics.html http://www.youtube.com/watch?v=Vv0ulNLRkWM And there's a good explanatory video out of Europe but I can't find it now.

I've been hitting the Wikipedia pretty hard looking for information on the topic.  I've found a couple of interesting articles:  http://en.wikipedia.org/wiki/Polythiophene http://en.wikipedia.org/wiki/Polyaniline My main reason for pursuing this as of late is because I think electrically conductive plastics offer a way to create high efficiency photovoltaic cells on the cheap (least relative to growing pure Silicon crystal without oxygen contamination).  Azodyes, which are popular doping agents for current thin film photovoltaic cells  can be linked directly to the organic back bones of the polymers, and i think this will make the conversion of photons into electrons more efficient. There's other organic compounds (specifically i'm thinking of metallocenes which can be used to generate positive valences, also known as "holes" within the molecular structure of the plastics) which can be used to dope an organic solar cell, but azodyes are the most obvious. Anyway... gonna hit up google. if any y'all have ideas post em up.

Turbine generator with heat pump

I got another weird idea that I like to share as I don't see me putting into reality anytime soon but someone else might do it for me after reading it ;) If you like me and call home where it is far too hot for most of the year you might have wondered how to cut the energy bills down. Especially if you in a remote area "off the grid". Sounds interesting? Then just do me the favour of posting here if you plan to put into reality and keep us updated ;) Technology has come long way and with some mirror like Mylar foil anyone can build big reflectors to use the sun for heating all sorts of things. Modern solar hot water systems are designed to produce a temp high enough to kill all harmfull stuff that might otherwise grow in our system but we can one step further: (Keep in mind it is just an idea with no prototype to proofe the concept works as expected!) Using heat pipes in a round reflector that is linked to solar tracker would allow us to boil water for as long as the sun is out there. Don't know if the flat types used for hot water systems are capable of producing steam but someone might have an old one at hand and is willing to test it on a sunny day? Anyway, assuming we can build a large enough array of solar ovens heating water pipes it is possible to drive a turbine with the steam. A linked generator of suitable size would now provide the electricity we might need to charge batteries or to power other things. But of course this would be total waste of the remaining energy in the steam! Plus we could really need some airconditioner, don't we? So in my vision we don't want to waste the water either, which mean we not only use the heat but also reuse the water to go back into the solar oven. If we now use an uscaled version of our RV fridge and instead of a heating element or a flame our remaining heat from the steam we can power a big fridge and an airconditioner on the same continous-cycle-ammonia-fridge type to cool what we need. Depending on the size and insulation rating of a house it is possible to be totally independent from the power grid during the sunny times. During the winter times the same generator can be combined with a ducted heating system where the waste heat of it is used to produce the steam we need. Of course integrating this into one unit would be the prefered option to keep the physical dimensions small. Combine all this with some good sized battery backup and inverter system and you might have enough juice to spare to make it through a cloudy day or two. Add some wind generators if you are in a suitable area to provide additional electricty. I think with new parts and some handy work it should be possible to create such a system for under $3000US. With access to some well sorted scrap yards even for free, not counting consumables, selants and so on... Sadly I don't own a house and currently not even have a garage to set up a little workshop so for now it stays an idea only... Tried to find some sponsors or at least people with interest to create something like this down here but it is like trying to explain quantum physics to a hundred year old in the retirement village. Sure, you can build something that would give me electricity and cooling for free? ... Of course it will work, so come back and show me once you made it.... If that crap could work, why are still buying fridges that run on electricty and airconditioners that drain our bank accounts?... We have 5 cooling containers outside runningon generators that use over 200liters of fuel every day and come try to tell me a steam generator can cut me fuel bills down by at least 50% if not more?... Just some of the more friendlier responses I got after trying to find some interest. Don't know if it is problem of the Aussie mentality or if I am just unable to make someone understand that we can use the scorching sun for free :( But I am not willing to give up on the idea itself, so what do you think? Oh! You have the financial means and access to create some prototype to integrate into a new cool house or  self sustaining home? Please feel free to contact me so we can start and make a living out of it ;)

No More Electricity!

This is more of a discussion then a question. Lately I have been wondering about the small amount of space that we have on Earth. In those thoughts, I began pondering about Thermodynamics (particularly, of course, the first law). Since energy can't be created nor destroyed - it only changes form - that most certainly means there is a limited amount. There's a capacity. Much like a battery, it can only hold so much energy. The Earth is essentially, then, one huge battery holding millions upon billions upon trillions upon trillions of energy units (it cannot be specified to electricity since it can change form). If that is correct, then my theory makes sense. If there is only so much energy, and electricity is energy, then one day we will reach that capacity, right? Let's create a hypothetical situation - we massively overbuild the world with the biggest skyscrapers that, with the newest technology, go thousands of feet in the air. Standard homes no longer exist, and the smallest of homes are at least four stories. These conditions cover every corner of the world. Power-plants are at a massive draw. Now everybody knows that you can't really "use" electricity for good, for it always returns to another form of energy - it can't be destroyed. So what if, with this extremely advanced society, electricity was used quicker then it was replaced? And this massive usage was continued until all of the energy that is "stored" in planet Earth is being used at one time. That brings me to the real question of debate - doesn't that therefore mean that all power-plants will one day, when this "Complete use of energy" comes, will no longer generate electricity? Is it impossible to believe that they will have no energy left to "grab" (electrical power plants don't create electricity, just generate and convert it"? Now, I may be entirely wrong. This theory could be 153(nice even number) percent wrong, but it's what I brainstormed. Any feedback or debate is appreciated ;)

What is the best wire for generating heat? Answered

I am making an Instructable for some contests. The basic concept is below: -Put two peltier modules on each bloodline on the neck -Put small heat sinks that takes advantage of wind on the other sides of the peltier modules -Use the electricity generated by the peltier modules (While skiing in ~20F) on a heat-generating device located near the hands -Cover the parts that I can with some fabric and possibly build it into a neck warmer or face mask So my question here is: What kind of wire should I use to generate the heat on my hands? I'm looking for high-efficiency and fast to generate the heat Also, do you see any flaws in my concept that I should change? Lastly, the most important question I feel I should ask here is: Will the peltier modules generate enough electricity to make a significant difference on the heat of my hands? My hands get cold enough to hurt when I go back into room temperature if that helps.

Question by knexpert1700 4 years ago  |  last reply 4 years ago


Small generators.

Most everyone here knows (I assume) how the generators work in RC cars and there's an instructable that shows it can be used to output electricity. Elementary science at it's best. If any of you have took them apart you'd notice it draws eletricity from touching the center metal pole. Two little brush/copper/zinic contacts. Basically I've been trying to think of ways to extract eletricity without having a need for them. They cause friction. Uh-oh, a few lightbulbs lit up in peoples minds by now and they're going "oh no not another person trying to beat the laws of thermodynamics and acheive perpetual motion" Yep. As we all know eletricity CAN jump if it's powerful enough and arc, but this doesn't make it too safe either. However it's a small scale model to start out and can be contained so the arc won't be a problem. My other problem is the calculations. They need to be precise. To get it working I need a low rpm generator that will generate high output. For this it requires torque which kinda kicks me, it will also need to use (I assume) rare earth magnets. So basically lets stick with my latter problem since it's more down to earth. I need a fairly small generator if possible (It can be larger if no other solutions are present) At least the size of a walnut I don't plan to make anything immense in size as I lack the funding. As pointed, small is key. Not to be redundant but to paint a clearer picture. It will also need to generate decent voltage at a low rpm speed. I cannot emphasis this enough because it's one of the key parts to make my idea function. Hum... Yeah that about covers it. So if any tech wiz's are out there that know of such thing I'd apperecaite it if you'd part the knowledge to me :P I'm also very aware that perpetual motion is eh, impossible... by current standards. The intention of this project is to deepen my knowledge and figure out why things won't work, figure out solutions and on so forth. A learning project for now and perhaps one day it might become something far more awesome.

Convert magnetic to electrical? Answered

I am trying to find a practical way to build a device to convert magnetic energy into electrical energy, some kind of generator or other device, there are several ways in which this might work in theory but actually building the device would be more difficult to figure out.

Electric Gramophone?

I've just had an idea for making an mp3 player disguised as an old gramophone, to be used as a set piece/source of music for busking. Problem is, I can't figure out how to pull off some of the details of making it... Heres the idea as it stands: Have an old gramophone that appears to be playing music from a record, but is actually playing music from an Mp3 player. I figure you could interrupt the signal from the needle to the amplifier without to much trouble, as you'd still need the needle there to make it move along the record as it 'plays'. It also shouldn't be too hard to hide a speaker in the trumpet or even embed it into the side of the gramophone. In an ideal world, it would also be great to have some general controls on the back, to select play lists and the like, and that's probably achievable my attaching it to a standard mp3 player. The tricky bit is that I want to get it to play when the needle is placed on the record, and stop when the record finishes, ultimately with a digital replica of the scratch sound that you get at the end of an old record. Does anyone have any ideas on how to go about this part? because I'm absolutely stumped... is it possible that the answer lies somewhere in using the movement of the needle-arm to complete a circuit while in certain positions? Any thoughts, help, ideas or suggestions would be appreciated :) .
