Pretty cool!

Rare earth magnetcs are easy to get on the web. Just type it in in google and check prices. I think the magnets he is using are about 20 bucks a piece or maybe a little less.

awesome, thats exactly what ill do… im making a turbine right now so those were some good ideas.

and lol, i used to make spin art with colored sharpies and a open cd player :]

dude thats good thinking try it on a tesla turbine!!!!!!

Look up magnet safety. The insides are Toxic. You can buy rat and ant poison at any Home Depot. That doesn’t make it non-toxic. It’s not that magnetism that’s toxic, its the Neodymium.

My point was if you use these, mount them so they don’t rub on the shaft and the outside coating remains undamaged.

Keep your insults to yourself.

I’d use a ball bearing on the shaft. No problem with the magnet rubbing and looks like total friction would be negligible.

you can buy guns in the US at walmart. Lead, like Neodymium, is a heavy metal and is known to be poisonous but readily available in plumbing, munitions and common electronics. Breathing neodymium dust can cause lung embolisms, and accumulated exposure damages the liver. Neodymium also acts as an anticoagulant. Its magnetic properties are not known to be hazardous.

this is good

so Mr Green Machine.
have you figured out how your going to connect your wires to a spinning stator.

something that will last and not short out when it rains.

i think you can create a near no friction by having the magnet levatate with out the metal stick in a vacume.

PappyDan, the stator does not need to spin.

In most configurations, magnets are mounted on the outer edge of the spinning disk and the stator coils are mounted on the outer edge of an opposing, closely spaced stationary disk.

@PappyDan.. and most of the diy generators I have seen have the stator coils embedded in casting resin to make them weatherproof.

Somewhere Nicola Tesla is smiling.

did you watch the video??
did you hear what he said??
since your trying to tell how their made, i am going to take a wild guess and say NO you did not.

Some of this is silly,however overall this group of topics and the general concepts are fantastically important. Does anyone think this material is discussed in American public schools?
The only way may children are exposed to these areas of science & creative aspects is via efforts such as this…..very important!

Those who take the time to make this material are doing a service they may not fully appreciate….Good stuff.

@PappyDan, alright, you are right, he did mention that a viewer sent him an idea of combining two turbines, in which both the stator and magnets would rotate. It appeared to be an afterthought and certainly was not the main concept presented in the video.

If you don’t believe my version of how they are made, perhaps you might look around a little more on the internet and find out for yourself.

1. copy and paste
2. send this to 2 other videos.
3. hold? your breath for 10 seconds
4. press refresh twice
3. LOOK AT YOUR BACKGROUND IT WILL BE FREAKY

I’m definitely not an engineer, so I may not be certain of what you are referring to regarding the longevity of the connection and the shorting out of it when it rains.

However, when I think of how to wire a moving target, I think of bumper cars from the carnival. The electricity is fed to the car through the metal floor and ceiling, which are easy enough to attach wires to.

Depending on the area, the additional friction may not be practical, but the additional electricity would be the payoff.

That comment was for PappyDan.

if i 50 of these magnets and each has 2.8 pounds of attraction force then if i put all50 of them together will it be like 100 sumthing amount of attraction force or the same?

When he mentioned shock absorber, I got the idea of car shocks. Maybe these magnets could be used on cars?

One problem with large and heavy turbines, is the start up wind required to initially overcome the inertia of the turbines mass.
For these kind of applications, carbon fiber is actually quite cost efficient. (you can make a pretty BIG 1-2kw turbine for about $100-150 worth of carbon fiber.) Combined with maglev you can almost start a large turbine with your breath… For stability i use ball bearing (top&bottom) for horizontal load. Remember its vertical load thats the big inertia problem.

Some high end cars (i think its Audi that does this), have feromagnetic goop instead of oil in their shock absorbers and adjust the
shock tension with an electric coil around the shock.
No electricity = soft ride…. lots of electricity stiffens up the shock and you get better handling.

Another thing to lower start up speed is to have several layers of magnets and coils where you ofset each layer to smoothen out the “magnetic gates” (turbine will “catch” on the coils as magnets move over the coils)… Now you’ll have more power at lower wind speed and even more at higher wind speed..
Playing with capacitors to utilize power thats too low for the inverter/controller to utilize…. not really happy with that yet though…

And to increase efficiency even more… using large static wind catchers/guides around a smaller turbine will also help overcome inertia, it will significantly increase wind speed at turbine and is very cost effichient as you can use large sheets of cheap plywood (weight and size not a problem as these wind guides are static) Depending on size, you could double to triple your wind speed at the turbine. (think of it as funneling wind into your turbine)
