Prototype Design Mk2 Wind Turbine and Mount in Aluminium

[DownhillAllTheWay]

Favourite word - "Acshully"! ;-)

Interesting clip, though! Excellent slip-ring assembly, but is the current carried through the hinges? It appears to be - I think I would have bolted a bit of copper braid across the hinges - like the stuff a car battery earth lead is made from.

The slip ring is completely insulated from the rest of the housing,and just two wires are connected to the ends of the brushes .

A Rolls Royce engineer designed the mount for me . it cost me £200.00 and the slipring is extra

Hello everyone!! The deceitful ppl with Energy4Earth are stealing vids & putting their label on them!!! Be Aware!!

super video windy solar!

well this looks like the £100 FE i bought from you last year and i must say it has out performed my expecs and i have had 60A at 25V at the DC end being ramed into all my 12V bats so cheers again I also got the 21.5 degrees FE blade for it and its the biz had to up my dump relay to the one off my range rover winch as i cooked the old 40A dump relay maybe twice a month so cheers again and keep up the good vids hows the 24V system you were setting up going for you now?

I like the brush assembly! I plan to do something similar for my next 12-ft diameter prototype, which will possibly put out 100 amps at 12+ volts=1200 Watts, so I will need a very dependable swiveling connection. I have found that if you flow on a coat of hard silver-solder on one or the other surfaces that are making contact(I use a 56% Silver content) that the electrical resistence and wear are greatly reduced, especially if you have a Bronze-to-Silver solder connection. Brass loses its zinc

Nice work, but i personally would prefer welded joints insted of screw joints in the frame. Weld can newer be shaken loose. Also, i would stay away from aluminum, but since you have the frame from rather thick stuff it should be ok.

I wonder if you have tried running the power down from the tower with a flexible conductor? I've had mine running in a 14m tower for a year, and the worst it has had was 2 turns in the pendant cable when untwisting it. But i guess it depends a lot of the wind site.

Nice video, the futurenergy pmg is from china same as renewable (they all are) may look like a brake drum but are steel stamped drum & cast& machined aluminium, by the way if you want pmg to last a decent time arrange some damp sealing (gets behind prop boss and rusts/seizes the bearing).

I love the British pronouciation of "Aluminum"...al lu min eee um. Enjoyed the video.

well made keep up the good work

First thanks 4 sharing a wealth of info -I dig it!

How exactly do you get the turbine to spin round freely while still connected to the tower? Would you mind making a short clip explaining that? Are you using bearings, I am confused - was that a vertical bearing...Thanx mate

The Government has announced that microgeneration technologies will from April 2008 become permitted development. This means householders will be able to take up microgeneration, within sensible limits, without having to apply for planning permission.

I like the design of te brushes, I have been trying to make my own ! try to minimize the number of contacts, the rectifier assembly could be hooked up before the brushes, apparently you have it hook up after the brushes, therefore you are using more brushes than you need. But it looks like good work anyway.

[windysolar1]

3 phase ac power exits the generator first then moves to the rectifier which changes it to dc then it moves to the brushes then down the pole to the battery's to charge.up to 50 amps so need large brushes to transfer current.

thicker wire = less loss as low voltage.

maby to simple but in an other disign (hornet on Ebay)does not use slip rings;

"No slip rings to fail or replace. Wire tension system inHornet 600 Series (600 Watt rated)

useing a car drum very very good idee.

its very strong and lasts long
