@drewb1994 Why do you say that? For a vawt to reach 3kw in a 10 m/s wind it will need to be 12sq m approx. depending on the efficency of the turbine. Its hard to say how big this is but it does'nt look that big.
@drewb1994 Sorry that comment was for OhYeahProveIt.. Clicked the Wrong box. To answer your questoin though this is a lift type machine( Search Darrious) The blades are shaped like an airplane wing which allows the turbine to rotate faster than the wind speed and they are far more efficent than drag type machines (search Savonious) Hope that helps sorry again.
ok, every verticle axis windmill video is impressive, but NONE of them show exactly how they are getting electricity off of them. Like the magnetic lev ones, i understand how they are magnetically doing that, but how is it getting anything into the alternator?
@arkansasbean Once the turbine force spins the alternator, the two pos and neg wires are hooked up to a power invertor, which converts it to a AC/DC which can be wired into a house, and/or hard wired so it fights the meterbox.
There is an easier method, which you take the pos and neg from the alternator and directly wire it into a component (or power supply) you want to use. Like a light bulb or radio. You would have to learn which size resister to use, or you might blow the electionic up.
@thegreatwoodlife So you just used a 1800 Rpm alternator ? I thought yours was a megnetic levetation verticle windmill that I am trying to build. I have build the megnetic levetated shaft and rotor, but I havnt came up with a sufficient way to convert the energy yet. Im thinking like a type of magneto design, what do you think ?
@arkansasbean in this video's case, the green cylinder at the bottom is likely the generator. For the magnetic levitation ones the generator is built in around the maglev, where you've got the coils, and on that piece there is one magnet, on the piece above it are the magnets that run across the coils and the second maglev magnet. Ball bearings are probably still used to control the lateral force on the shaft itself.
the real question of course is the real world test of wind speed and performance at a given reasonably frequent speed. Aka one that gives the most power for the most days of the year. most of the high performance units perform well at high wind speed but in the everyday guys life, a drag machine will probably be the best candidate in low speed turbulent city wind
What does that honestly matter? Volts mean nothing without knowing the amp's... All watts are is just volts x amps. You can always convert the volts to what ever you need.
rating a wind turbines, means the maximum open circuit voltage multiplied by the maximum short circuit current that gives the max rated Watts of power.
3000W = 220V * 13.7Ah. Although this is not enough for constant use of 220V appliances (30Ah), those are not always on. Also, 110V doubles the amperage to (27Ah), which is more than enough for standard (15Ah/20Ah). Answer your question?

Probably 220V or 24V. Those are the main ones. Also, that one wasn't mounted right, if I'm not mistaken. Aren't those supposed to be mounted at least 30 feet above any obstructions within 300 feet radius?
the beauty of the VAWT design is that it can take wind from all directions at once. so the mounting guidelines are really quite open ended. they are ideal for residential rooftops, building roofs. etc.
they still preform best in clean air, but VAWT is the type to look at if you don't have the acreage to allow for the "fall zone" for a 60-70 foot tower.
That is genius! Close to frictionless as possible with magnetic levitation.
I'm guessing the more magnets around the circumference, the more efdicient.
If it's truly 3000watts, maybe one is only one you need. SWEEEET!

Notice how the camera cuts out when the wind starts to slow down.
B+ for effort.

It's always helpful to build a fence next to the turbine to block the wind.....;-)

Um one thing, think of a 13 amp plug on most appliances. so you have the right sort of though but it wrong.
it would power household appliances not taking into account that most things dont actually run at 22V and 30 AMP's

That is only true in a pure resistance circuit.
when you have inductance in the equation such as motors, I * E does not equal P

SO true even putting one in your basement will turn from just the movement of the rats running across the floor. We call that rat wind power.
