  • The real Darieus combined with a drum runner, good idea! Nice job.

    I would like to know how you made the darieus blades

    Ed

  • going fast o.o if a piece of metal flew off it would certainle kill ya

  • I still think that the VAWT is probably the best application for a boat. I think that I may start building them for the marine industry. I own a small company that produces electronic components for marine purposes.

  • VAWT provides the solution for both of marine boat and household market.

    It solves the wind heading as well as wind turblence effect since it is always in the wind.

  • @conspiracy777 PLEASE EMAIL YOUR CONTACT INFORMATION TO DONALD

    zsebank@gmail.com

  • I prefer the vertical one over the "airplane propeller" designed one.

  • me too

  • very efficent

  • how to store energy effectively with wind generated power??

  • by deep-cycle rechargeable battery

  • I would trade a few dead birds for FREE energy!!!!

    That's a fact!

  • how is that bird safe?

    and vawts are actually ballsack because they loose 50% of speed when the blades turn into the wind

  • My wind videos are a funny response to those who opppose wind power...

  • Where can I see more n these on the web?

  • oh,I heard they were speaking chinese.

  • wooow! is this to shows difference between the two device? is the faster moved only by wind? media don t talk abuot this in italy

  • POWER !!!!!!!!!!!!

  • cool!

  • I love it!

  • If you Short the output of the Turbine you will get Stoppage.

  • You can see from the last shot in this vid thats its literally blowing a gale. That really slow spinning HAWT you see at the beginning obviously has something wrong with it when you look at the four turbines all spinning full tilt at the end...

  • These aways produce much less power than the horizontal ones. They only look pretty, otherwise useless.

  • according to this side by side, you may be wrong. the rpm of the verticle one is much higher. as we know power = torque * rpm. it looks good to me.

  • Savonius=twice less efficient than the Haxis,that's true,BUT is much easyer/cheaper to built/maintain/install and the generator/wiring are on the ground!!You can simply built a bigger Vaxis,with bigger area, to have a much more special thing than an Haxis WT.Neocons want us to rely on their 60+ft Haxis,whos blades are IMPOSSIBLE to built in a small or medium workshop,they want us to DEPEND ON THEM,just like with the oil.B free,B smart.Avoid/reject govts. Haxis pro-

    jects.

  • lol Neocons... funny cause it's true.

  • vertical seems to KICK ASS! :P

  • JEEZE!!! We really need to replace ours here in California with these new ones!

  • vertical axis is better!

  • I've seen this video and have done it my self(/watch?v=0mTal3Skez4). Its a great way to learn about how air affects on objects. The bearings create a tornado affect with the air around them making them spin easer and longer. So what I'm saying is the vertical turbines can crate tornado affect. This makes less resistance and more efficient for more electricity.

  • Does it works near highways

  • No problem as long as it is followed the highway's regulation like 9 meter height.

  • Hello. The wind turbine comparison test is very interesting. The speakers are speaking Mandarin. Could you tell me where this was done and when? Best regards, Bruce

  • It was installed in Taiwan in March 2007.

  • thanks... never saw before a vertical axis turbines working,,

  • bearings are your enemy, I would look into constructing a high powered natural magnetic bearing you should see several fold increase in power and higher rpm's in excess of 3 fold

  • for efficiency we should go big. The best turbines have the same wingspan of a 747. Engineering larger ones would pay but it gets hard... These small ones could kill a lot of birds in comparison and aren't as economic if you are on the grid. But for off grid they can be useful.

  • Even a stuid young bird can live with it since the rotation is always the same without moving toword to the wind direction like the conventional wind turbine!

  • Big one is good for industrial application. The market segment we are working on (>10KW) is for household market which has space limitation.

  • There is a building on the left which causes the turbulence problem to the conventional "fan"

  • I'm all for wind power, but what's the advantage of the vertical axis? The eggbeater windmills were over big for a while, but they weren't more efficient than the standard windmill.

  • Free of High frequency noise and Turbulence impact are the major advantages which bring this Micro wind turbine to the urban life with green power.

  • OK, gotcha. Very good.

  • why is directional turbine better than vertical/omniturbine?

  • From what I've read, they produce more output in more laminar airflow situations, but in areas with high turbulence, such as in city environments, the vertical would produce more output.

  • Vertical is in the wind in 3D direction, and Propella one is in 2D and need to move forward to the various wind direction.

  • Vertical Axis interested me. Especially start up speed and the balance.Also vertical if made ligh would be good becase there is less weight to turn the blades. Maybe? lol .Great video and hope to see more!

  • The 2 on the side, why one spin much faster than the other?

  • Thanks for your information.

    Mr. Paul Gipe is a famous expert in wind turbine industry especially in HAWT.

  • Thanks for your positive comments. We do believe that Vertical Axis Wind Turbine is the right solution to the household and urban application. By the end of 2007, 5KW and 10KW will be ready to the market.

  • Nice design. To learn all you need about wind power & installing a wind turbine of your own, I'd suggest reading "Wind Power" by Paul Gipe.

  • the wind speed is around 5-6m/s. and all turbine are rated 400W. For the VAWT, the rated wind speed is 12m/s, so it generated around 1/8 of rated power, that is 50W. It was installed in one college at Hsinchu, Taiwan.

  • Curious what the wind speed is during this video. So many different designs! How did they all work? Where was it filmed? How much electricity was generated?

  • It is quiet and the noise comes from the wind hitting the microphone, but the High Frequency Noise of Traditional Windhill appears while heading for the wind
