Title: Magnetic rotar Wind Turbine
Post by: glassman on October 06, 2008, 08:02:12 PM
Just thought I'd solicit the opinions of those here about these VAWT with magnetic rotars:

Any thoughts on the claims at energy production of these units

I like their design, would like to know more about the electronics of the generator and such.

I thought about this years ago - my idea at the time was to have a generator of the type shown in the video and install it horizontally at the top of a hill, and landscape the surroundings to maximize the shearing effect. As to whether this setup is more efficient than other designs remains to be seen.

This would work better if the blades were skewed and funneled the wind out the bottom.

You know what really blows me away, why why why arent they putting wind generators on the new electric cars?
Sure its not ou but it would have to extend the range.
If I had money to invest I would build an aftermarket feature that would blend in, adapt to fit the car and build generators for these cars......... They would sell especially if incorporated into the mirrors or an added feature for the car.

Mirrors=spoiler's=hood scoops=door scoops any added feature that would compliment the car.

There there's a multimillion dollar idea, remember me when you have so much money you dont know what to do with it all.

I bought a ford ranger the other day that has a blown head gasket, Im seriously thinking about pulling that gas dinosaur out and going electric.
I was looking at the bumper, the way its made it would be perfect for a wind turbine.

A hood scoop with a couple of turbines would also cool the motor.

A lot of vehicles especially trucks have ground effects this would be perfect for wind turbines

Post by: Dave45 on May 16, 2015, 02:39:44 PM
If the forced air were funneled into a tube then multiple turbines could be added, the tube could be ran to the back of the car like a gas engine exhaust pipe,  most of the noise would exit the rear of the car.

I wonder if the tube had wind directors that would cause a vortex then hit the turbines

Some RnD would have to be implemented for sure.

The grill's in most cars or trucks could be converted into wind tunnels.

I can get a warp 8 motor for the same price as a rebuilt crate motor for the ranger  :D

The more I think about this the more appealing it is,

solar panels could be incorporated into a lumber rack for the truck

I like it, a pet project.

A learning experience

An investment of about 4000 usd should power a small house if you do your own installation.

An exercise bike with a pmg would be a good addition to his system and a good emergency backup.

So if I took a vawt turned it on its side mounted it in the back of my truck where only the top portion raised above the cab I figure I could run at least two pmg's - one on each side

The pmg's could be the bearings for the vawt one on each end.

Its doable

I guess turning it on its side it wouldnt be considered a vertical axis wind turbine but this  gives you guys an idea

So a pmg in a 30 mh wind will putout about 40 amps
Two pmg's should pump 80 amps into a battery bank.
That should extend the range of a ev.

But, you also have to factor in the aerodynamic drag, which would be considerable if the device is under load as in an EV.

Hey Bill
 Yes all windmills have drag and most are under load ie charging battery's.

I think a vawt would have more aerodynamic drag standing out in the open than it would mounted in the bed of a truck.

Wind dividers show an improvement with the vawt and this is the reason.

OK, good picture, now I see what you are getting at.  This position would seem to reduce the wind braking effects that a vertical mount would have.  In other words, like this, it is more like a water wheel with very little opposing wind forces.

Post by: Dave45 on May 20, 2015, 03:50:05 AM
Exactly like a top loading water wheel.
If a lumber rack were added with solar panels and a vawt,,,, well it would be interesting to see just how far it would go.

Two pmg's could be attached to the windmill, they would also be the bearings on each side.

You are correct, that is very simple and cool because it looks like it works.  Simple is always the best way to go if you can.

Great video.

Hey Bill
 Iv been studying electricity and electrical theory for awhile now and its been fun but realistically solar and wind is our best option for now.

I have a small older travel trailer im going to set up off grid, Id like to set my house up but that would be too expensive and I like the idea of being mobile.

I'll still experiment when I have time but my money is going to go into solar and wind until I get my system up an running.

Thats not how the wind actually passes over the bed of a pick up truck. It makes a rolling effect inside of the bed that the air stream passes over. Causing a vacuum behind the cab. You might want to set up some streamers in different places made from ribbon and view the air flows for yourself. That is why a pick up truck gets better millage with the tailgate in place and closed. The friction of air to air is less then air to metal.
  Im not trying to be picky just trying to save you and any other person from wasting time with an inaccurate mental image of the air flows.

Post by: Dave45 on May 25, 2015, 01:40:35 PM
Hey Doug

You may be right some rnd would be in order, but Im sure you could just raise the hawt until you got maximum torque.
The vacuum created may be to your advantage,
I dont know if vacuum is the right word more like an eddy current.

Hope this isnt too far off subject but Iv had this nagging idea for a long time and I need to try it I know, just thought I would share it.

Magnets act like gears if you take a look at the Searl device you will see what I mean, now the Searl device acts like planetary gears.
https://www.youtube.com/watch?v=ECljAo1q1RQ

So if we build coils in this arrangement will they interact.

We pulse coils with dc and ac but how many have tried using straight dc and see if the smaller coils will give energy to the larger center coil.

If the outer coils circumference is smaller than the inner coil it would seem the A vector field would be spinning faster than the larger inner coil.

Will the three outer coils spin up the inner coil.

Is this what Hubbard did.

Post by: Dave45 on May 25, 2015, 02:35:17 PM
Something else I forgot to mention, when I was freezing coils I noticed the A vector field in an air cored coil ran outside the coil but the field runs tight up against the core if a ferrous core is added.

So if the outer coils are air cored and the inner core is ferrous will the outer coils give their field to the inner coil.

Post by: Dave45 on May 25, 2015, 04:41:18 PM
So if the outer air cored coils were fine wire adding resistance and the inner coil was course wire and weighed the same as the outer coils wire combined will they work together.

Can amperage be increased.

or if the outer coils were course wire and the inner coil were fine wire with the same weight ratio can voltage be increased.
