Vertical Axle Wind Turbine(VAWT) with noise decreasing upgrade
by random, published
Description
according to the labmanager the twist in the blades removes the pulsating noise
the normal darieus makes.
it`s made in openscad but the code is a little messy.(apart from openscad I only wrote some hello world like things for python tutorial exercises)

Got a Rostock? You could make one that's a meter tall if you're rostock is tall enough ;)
I just found this VAWT! It is so remarakbly the same as the one I designed, it is uncanny - and yours came years before mine!

Has anybody made one with support material for the makerbot? I was thinking it might be easier to print the three wings and the center shaft and then stand the connector blades upright and print those. Then maybe hot glue those together. My cad skills are lacking but I am giving it a go.

this is great I was toying with a turbine design, but this is way simpler. All we need to do is mount this on a bipolar stepper motor, and a simple AC-DC converter and you can trickle charge a battery to run a RepRap/Cupcake. a bipolar stepper can also get good voltage from lower RPM.
can sections be stacked to get a higher foil? what is the optimal size for this?
Its amazing.... Did you realy know what are you doing here? This is absolutley usefulll forverysmall dynamo (Electicity producing machine) techniques. With a couple of some hundreds of theese you can energize your home... the dynamos are relay cheap... what i didnt find until today is a turbine device wich doesnt need rekalibration into the wind... i will look for the dynamos and then goreturn... realy cheap deviceto make it... electricity for every house... yeah... in every size.... Great...

Did you see QuietRevolution.co.uk ?
no I have not seen that site before,
read about this type of turbine somewhere else.
Maybe for the random MakerBot - add a thin vertical block under each strut - keep 1mm space to the axis making it a break-away support material. :-) Hmm these could probably be stacked as high as one desires. Cool design.
