HEARD OF NEW WIND TURBINE WITH NO BLADES?
Nov 16th
Question by Zoe:
Heard of new wind turbine with no blades?
I heard from my biology professor about a new type of wind turbine that was designed in Michigan that doesn’t have any blades, so it doesn’t effect birds & bats. Instead it has this circle thing at the top that twirls around.
Has anybody heard of it? I am trying to find an article on it so I can add it to my wind turbine paper but I cannot find a thing.

Q&A: ARE THERE ANY REASONS WHY A LARGER NUMBER OF BLADES WOULD BE MORE EFFICIENT ONA WIND TURBINE RATHER THAN LESS?
May 13th
Question by Isabella:
Are there any reasons why a more massive number of blades would be more efficient ona wind turbine rather than less?
For science, we did an experiment to determine whether 3, 5 or 7 blades were more efficient on a wind turbine. Our results showed that seven blades produced a higher voltage, and three the least.However, now we ahve to find theoretical background which would support this, and everything I find on theinternet states three is superior than more. does anyone know any benefits of having more blades?
Thank you.

10.6 FT (127.2″) DIAMETER. HIGH EFFICIENT WIND GENERATOR BLADES NO HUB, 3 ROTORS
Dec 28th
- Power – Applicable for 1000-1500 watt generators
- Start-up Wind Speed – 6.7 mph or 3m/s
- Nominal Wind Speed – 22.4 mph or 10m/s
- TSR – 6:1 at heavy load, 8:1 at light load, and 10:1 without load
- Diameter – 10.6 feet or 127.2 Inches
Designed and made to pick up the wind power as much as possible. The efficiency is graded as 0.48 in converting wind power to the mechanical power, which is at the very top end (the highest is 0.5). The exact same blades are widely used in commercial wind generators. The performance of the blades is much superior than home brewed ones.

HOW CAN I FIND A DISTRIBUTOR OF WIND TURBINE BLADES?
Nov 4th
Question by ly_glass:
How can I find a distributor of wind turbine blades?
Hi, all
I am just wandering how to find a distributor of wind turbine blades. Situation like this, we company manufactures small wind turbine blades. At present, we have many customers at home, but a huge zero for our market abroad. Does anyone works in this field? Or do you have friends engaged in wind energy products?
I would be appreciated if someone could give me suggestions.
