Re: Wind generator charger schematics (or load of baloney ?)

i have an unregulated wind generator here .. i still need a regulator . will eventually do something simple like a relay and a couple of transistors etc .. it will light an outside light when the voltage goes over a certain point at the battery like 14.4v or something like that . will have to try a 24v light for this or something with its own regulator .. the generator can go up to at least 18v open circuit ..it blows 12v car headlight bulbs
i might even use the low battery voltage warning light circuit i built to switch the relay .

I agree with solar power being the best and also with the price-to-payoff ratio of DIY-ing wind turbines like this. The redeeming factor in this case is that the guy often sources stuff for free or from scrap yards, so it's not THAT expensive. Converting the dirty sh!tty output from the dirty and sh!tty generators he builds into actual usable energy for home use is my job in this deal

Right now, I'm thinking of whether it'd be possible to just stick the awfully unstable output of the generator directly on the mains input of a SMPS to charge some batts with it, or will it get destroyed, or at least severely limit its lifespan doing it this way. The other idea is to use a FULL BRIDGE RECTIFIER to get my unregulated DC and stick THAT on the input instead. I'd still be all over the show, but not as much, due to the smoothing caps. Capacitor inrush current would be an issue and unless the wind is particularly strong, it might stall the blades and keep them from turning..only one way to find out and that's to actually build something.

I'd then maybe design like a little circuit to toggle between the battery and the generator for powering an inverter which then runs the house or whatever....

It's not hard to generate electricity from something moving, even better when it's just rotating - because things go back to their original state.

Just going back to Maxwell, all you need is to move a magnet over a wire and you get some electrical energy. The faster you can move a larger magnetic field over a large amount of wire, the more energy you'll draw from mechanical energy and make electrical energy.

The question is whether you make the magnetic field from electricity (alternator like in cars) or from magnets (generators). Doesn't really matter which way, just need to design it such that you come out ahead, not really a big deal.

All you really need is to just get a permanent magnet motor and spin it. You get your electrical energy, don't need anything else. Just that it may not be the voltage/current/power/time consistency you need.

For me, getting that motion/rotation costs me more money than just buying electricity from the power grid. Solar energy is better in this respect.

Ok, at least now I know what it is I guess it is not commonplace in the field of high-power wind turbines, since I see most projects involving friggin' AA batteries I'm not sure how it would get hooked up to the guy's generator though...

Let's instead focus on how to ACTUALLY design a wind turbine and what the electronics that come after the genie should look like - I'm talking mostly OTS stuff. I'm fully aware that we're not about to compete with the factory-built stuff that already exists on the market, but at least for home use, mostly for fun and for learning stuff....

The circuit is a "2N3055 joule thief" which is very common in the "free energy" crowd. Basically, just a primitive one transistor boost-converter.
To sell a fake generator, it's common to show more volts out than in = aliens, unicorns, magic - helping generate more.
When you actually measure power in and power out, usually one battery is being drained while the other appears to be charging. It seems to fool the mind.

The neon acts like a gas-discharge tube and protects the transistor from over voltage if a battery is disconnected when it's running. These are really low tech, low efficiency and not worth building.
Instead, why isn't the generator outputting more voltage? Add turns of wire or speed and get the voltage you want in the first place lol.

Good day folks. A former colleague of mine recommended me to a relative of his and I got to speak to this man today in person. He's a bit of a mad scientist/tinkerer sort-of guy - just my kind of weirdo Apparently this chap builds all sorts of generators and wind turbines in his little shop at home and sells them here and there. He even showed me some footage of some of his inventions in action out in the field. However, as he himself very kindly put it, he's not good with electronics - he just designs and builds the generators (from scratch, I might add) and turns to others for the electronic side. He doesn't have a regular guy for this task, which can be a red flag that people don't like working with him, despite him being very kind. There's only one way to find out and that is to give this guy a shot and humor him....for a while at least.

Have a look at these two schematics he asked me to build for a small-scale turbine. Right away, although I have close to zilch experience with gennies of any kind, these look like nothing I would stick on the output of a generator. Apparently, someone else drew them for him, who in turn got them from....somewhere. Maybe I'm a noob and they're actually some really standard setups that just don't click with me, or maybe they're just complete baloney that would never work for this, or just go pop within seconds....

There are WAY too many questions that need answering here, starting with the generator itself: he claims he can build any generator, in any shape and size, with any number of coils...which he showed me on his phone - told you the guy's nuts In the larger schematic, the outputs from the coils (2 coils in this case) are those 4 dots in the upper-left (that's the Romanian word for "coils" BTW ). Trouble is I'm not sure how the pairs are supposed to be arranged: is one coil the upper two dots and the other coil the bottom two, or are they the left/right ones instead ??? What sort of output are we expecting from them ??? Number of turns ??? Wire gauge ??? Poles, magnets ??? Not a single capacitor in this schematic. Neon lamp across the E-C junction of the 3055, why ??? It's been a while since I had to reverse-engineer something, so although this seems simple on paper, there are many things I don't get - not to be rude, but it's almost like someone threw random components together. The bar is set too high for this thing I can't see how it's expected to rectify the AC those coils SUPPOSEDLY spit out, regulate it and then stuff it into the batteries. The only thing that I CAN kinda see is D2 blocking B1 from attempting to turn the generator. The whole thing looks like it's trying to be some sort of regulator....which it isn't because there's no reference voltage set anywhere (zener anyone ???) and no series-pass element...unless one coil acts to limit the speed of the rotor and that's your regulation.... That 5K.....pot (?) is another thing that seems unfinished. No, it's not an error - the chap says that's how the other guy drew the schematic. Might as well be a fixed 5k there then.

How I would do it, even with 0 knowledge, is stick a rectifier on the output (3 phase if necessary) smooth it out and feed it into a DC-DC converter - MUCH more efficient and LIKELY to work, at least at small scale....

Is there even any point in building this ???
