Home made wind turbine update 2 P2

This is part 2. We did some modification the first design. We now have double the amount fins as before. Before at high winds it would stall and now with more fins we have more trust. We have also fitted gearing and alternators.

an outer frame would help center the top and take out a lot of the wobble.

@2tourVet thanks, I really appreciate the advice

Looks cool... needs some work, but I bet you're having fun building it! Can't wait to see it when it's perfected. Keep it up... I like it.

@Prancinglion1 Thanks will do. I have some other projects doing right now, mainly farming stuff. Ive got a bio-intensive garden maintaining and bigger mono culture farms...not to menetion work. Appreciate the comments tho

There are so many improvements that could be made 2 this turbine, starting again maybe a better option. The disadvantage with vertical axis turbines is that blades must battle against an oncoming wind. Ur design has over emphasised this. Blades should be a slender "D" shape or slightly curved in cross section resulting in a difference in air pressure and movement (think aeroplane wing). They shud also b parallel 2 its opposite.

An alternator would require around 500rpm 2 produce serious current.

@Rockinghorseshart OK THANKS!!! Appreciate the comments

if you can move the chain to the smallest sprocket on the jack drive pulley the alternator will turn faster...

the filming is sooo bad!

Gear ratio is way out of wack, huge initial gear, tiny little gear on alternator.. If alternator even work?!
