WIND HANDCRAFTED BLADE TURBINE WINDMILL ALTERNATIVE GREEN

http://www.greenpowerscience.com/
This blade design is cut with only a table saw in less than 1/2 of an hour. One person could rough cut 50+ 8 foot turbine blades in one day. GREENPOWERSCIENCE.COM This is the Quad Design.

What type of wood did you use for the fan blades?

[GREENPOWERSCIENCE]

Regular 2x4s Pine I think, It is one year with no coating and still works good.

how do you prevent it from overloading the 12v deepcycle batteries i understand how you keep the power flowing 1 way and i have 6 deepcycle batteries and a 800w 12v converter i used to use in my truck i want to see if i can atleast power my laptop and a lamp off some small vertical generators as you have shown on another video im very curious to know if its possible i live in a small neighborhood that wont allow for a larger generator

[GREENPOWERSCIENCE]

You use a charge controller. They cut off if the voltage is above 14V preventing a fried battery bank.

A nice piece of work, don't want to negate your efforts, but from my experience 'one angle' blades like these spin up well initially, but never spin quick enough to make any power, the tips stall out, shallow the angles near tips and you will get much better results, keep up the good work!.

Thank you for the comment. We do not get a lot of wind where I live but in a thunderstorm, this 8' diameter blade reached about 120 rpms in 15 mph gust. They do provide more torque. The nice part is the cost. This 8' diameter blade cost $6 so you could build a bunch with a geared generator. On person who built some living in a much winder are told me they got 300+ rpms on a 10' blade. I made a smaller 4' one and it spins almost too fast to see in a good breeze. There is an easy step to taper.

Hey Dan! Do you have engineered drawings of the blade surfaces and what their

pitches and weight distributions are. Would love to build this project for

a wind farm demo here in West Kentucky.

Interesting... Is that on the same wooden base too? You have got to have a similar climate as us down here in South Spain.

Erh erh ... This is a family show... :D

Love the music, sounds like Enya's gettin it on with some animals hahaha!

Hi Dan and Denise! I loved this video but instead of music you might have continued to deliver specs and methods verbally or with text. Nice video just the same - no heavy crit here. I think your work is brilliant. I just wish you lived on my block here in San Diego. Thanks for your response regarding Energy For Earth scam. Keep on!

Hi again, love the videos. It's always nice to see people putting out DIY tech, making people aware that they really don't need to rely so much on big oil. As far as DIY windmills are concerned, if you google "Hugh Piggot" you'll find tons of info on building wind gennys. In fact you can find it here on Youtube as well. With his info, you can build complete wind gennys from start to finish.
