Shop air (~80 psi) drives this stainless steel and polycarbonate Tesla turbine. A Binsfeld torque meter (resistive strain) is attached to the shaft, but you pretty much only see a blur of the outline of the battery and transmitter.
The turbine was made on an Omax waterjet at the MIT Center for Bits and Atoms in support of fablab research.
