Tesla Turbine #3
first two were CD's on a skateboard bearing....
new turbine: 1 hard disk from a PC 1 2" piece of 1/8" tubing 1 small piece of plywood... approximately 10 minutes in the shop. the disc's don't have end plates. No back plate or exhaust plate. The runners don't have exhaust holes... I drilled 8 holes through the runners for exhaust. drilled a 2" hole in the case for exhaust drilled a 1/8" hole in side of case for nozzle. 1/8" tubing with a 45degree angle ground off the end. piece of plywood for keeping nozzle straight Duct tape to hold it together. now I have a case! The case for the hard drive will fit right over the discs... it isn't round like Tesla's design, but it works.... I have no idea how many RPM's I'm getting. it's going fast. There is no output shaft, so I cannot connect a generator... I might hook a meter up to the stepper motor on back.. I might be able to get some power out of the thing. It's just like a gyroscope. Spin it fast and hold it, and it wobbles in your hand from ?centrifugal? force. Rich |
