Howdy group!

I'm 2 weeks away from having my own garage.  A long time dream about to come true.  I won't have to clear my work bench (dining room table) every time for a meal.  So now I want to make a scale working model of my turbine design using clear plastic.  That should also help flesh out some difficulties in the design and point to improvements without much expense.  I plan on using a 2 liter soda bottle as an air tank on my desk as the energy imput.  I could take it up to 110 psi.  I'm thinking on using metal disks on the runners about 3" in diameter.

Problem:  I'm thinking that even as a demo unit the power output of this thing would be more than enough.  What do I do with the output to demonstrate the power?  Do I use a 6" bar and a fish scale showing the stall torque?  Do mount an electric motor and use it as a generator showing the electric power output?  Do I use a gear reducer and mount a wheel to make a small car powered by air?

This will be my first construction of a TT.  I've been paying attention to all the details.  Any suggestions on the desk top demonstration model would be greatly appreciated.

Does anyone have the calculation of the work (energy) potential of a 2 liter volume filled with compressed air at 110 psi?

RE: [TeslaTurbine] See through working model

I launch water rockets using soda bottles.  They are pressure rated to 130 psi with failures going as high as 180 psi.  They hold a lot of energy.  They can push a rocket body, fins and nose cone over 200 g's off the launch pad at speeds approaching 200 mph.  I'm sure.

I'm thinking that with a TT and a 2liter air tank I could easily out do AirHogs' piston powered car.

• Joel the fish scale sounds like the easiest way to go and cheaper as well , it will give torque as well power out put. I am using the same it works fine

Joel the fish scale sounds like the easiest way to go and cheaper as well ,
it will give torque as well power out put.
I am using the same it works fine although I have fully completed a few mods
to it. The local University [college] uses this method to demonstrate to the
students, so I figured it would be good enough for me.

Mike, Sorry I addressed the previous message to Joel. I agree with Joel I
worked for number of years in the packaging industry and I would be real
nervous around a P.E.T. soda pop bottle with 100 psi or so in it.
Try an old fuel tank from a kerosene stove or lantern or a pressure tank
from trucks brake system.
Hope this helps
Neil
