Tesla Turbine
built 672 days ago
The Tesla Turbine is composed of discs fitted closely together to one another. Gas is directed over the turbine at high velocity. Molecular adhesion to the surface of the turbine spins it and the attached crank shaft at very high efficiency levels.

The idea of creating a Tesla Turbine with CDs is very clever. And in one of the tests of the guy, you can see the CDs turn so fast that the thing explodes. If you watched Mythbusters, then you'll know it takes a lot of RPM to make a CD disintegrate.

It has been said that vane pumps work by friction, and Tesla Turbines work by adhesion. This means that, in a sense, the molecules of whatever is being pumped are cooperating with the resonance created by the fundamental turbine design. More research is certainly needed on this point. If true, it implies that Tesla Turbines could be precisely calibrated to particular jobs by being made of harmonious materials.
