It’s more stable in …
It’s more stable in high winds as a horizontal installation, and with the right bearings you can easily cut down on friction.
would be more …
would be more efficient if it was vertical… I mean you should get less friction, some people were experimenting with a turbine here but it was vertical and standing on liquid or something like that
Have at it VU. Be …
Have at it VU. Be sure and post your results here. We are salivating with anticipation.
Looks like all you …
Looks like all you need is a steel 55 gallon drum and a length of tubing, some bearings and a couple meters of speaker wire.
How is this …
How is this low-efficiency? This product takes no electricity to operate, and can help support a neighborhood grid.
i’d be embarrassed …
i’d be embarrassed to show that to any prospective customers or even on youtube.
i think the guy is a scam artist.
What is it with ALL …
What is it with ALL the low efficiency wind projects? It seems that an appreciable knowledge of aerodynamics has all but evaporated. I’m speechless.
I am without speech.

It’s much cheaper to build one yourself. If you want instructions on how to do it or if you have any questions, feel free to contact me. The same goes for anyone interested in building their own wind turbine.
Getting a …
Getting a government grant for THIS! almost amounts to fraud. How gullible can the government be?
vawts are known for …
vawts are known for low efficiency (about 30%)

bec9112001: I agree. As it stands now it hardly moves. Add the magnets, or generator, and it will come to a almost standstill. This design is well known, what is new here?
That’s what i was …
That’s what i was implying, sorry. Attach this turbine, vertically, to a pole, use some high-speed-low-friction bearings and it will catch the wind from any direction. Why they decided to implement this turbine horizontally is beyond me.
or simply arrange …
or simply arrange it vertically
because the …
because the thermals always blow the same direction.
I think they have …
I think they have thought of that.
I don’t think the design will have much resistance.
since it’s designed to operate in low winds also, it will probably trickle small amounts of elctricity continuously, and larger amounts when the wind is higher.
It’s not any different than a wind mill except the design is more space efficient, and the physical shape allows it to operate in lower wind.
$700 to make? You …
$700 to make? You really need to build on a shoestring like the rest of us. Try about a seventh of that.

That’s truly amazing! I slashed my electric bill in half! look here: gdolim8.wspower4.hop.clickbank. net/?tid=yt (delete the space before ‘net’ when your pasting it in your browser)
3-5 kwh per day is …
3-5 kwh per day is 1095-1825 kwh per year, means 1/3 to 2/3 of my E-energy consumption per year. That’s in my view very good when this would with the shown windmill.
that turbine wont …
that turbine wont work, it doesnt even have a motor/ generator at the end of it… its just a piece of decorative metal, once you ad a motor to that to reciece the energy the forces of the motor. the push will limit the speed greatly with the wieght of this contraption they built
thanks , but for …
thanks , but for some reason if you put a wind mill horizontel it works better but they could add a tail fin
Good idear!
Good idear!
kW/h is a measure …
kW/h is a measure of energy, one kW/h equals to 3,6 megajoule. Perphaps you mean 3-5 kW/h per day, witch roughly equals to an average output of 170 watts. That is not much.
If you instead mean an average output of 3-5 kW, that is a completely different story. In fact that is quite much for a micro powerplant, you will need to build a very large turbine to harness that much wind.
If i would build a wind turbine i’d build it from scrap, and i should be able to build it for free. So can you.
