Tesla turbine

thingiverse

this turbine, invented by Nikola Tesla, use the Coandă effect to move the disks, in this version i have made some changes, the airflow is ejected by center of turbine, in this way the efficiency is increased because all the surface of disks is used, dont need to make holes on disks to not damege the balance during high speed spinning, i'll upload the instructions to complete it soon :)
