This is a printable housing for a 3-phase generator driven by a boundary-layer effect turbine. The turbine is constructed almost entirely from scrap hard drive parts.


Works really well!

I will update this with instructions as time permits.

Nice work Joe. The turbine worked great, but i think i made it go to fast. I burn out the bearing in the hard drive motor.

Could you post instructions on this - or at least some hints, or a youtube video? I'm interested in making one, but it would be very helpful to have some advice before trying.

Hi that is an verry coo design ,.. Question do you use the hdd motor for generating the energy ? If yes how much power do you get from 5v ? or more ? i am about to build an independent system and search for energy harvesting methods ,.. i did order tesla turbine plans over the internet they are ok but the generator stuff is an issue so any hint welcome thomas

Yes, I am using the HDD motor as a generator. Each phase puts out around ~9VAC when up to speed. I have not had a chance to rectify the power and run it through a dummy load to measure the current output.

hey joe, looks great!

how did you cut the holes in the platters?

I ended up taking the platters to a local machine shop and they used a drill press + rotary table.

;-) excellent, i have a few dead drives i've been looking to do something with!
