Turbines

Turbines are very important pieces of equipment that can generate pressure by spinning very fast.

They do however require two very important things for good operation:

Bearings - and good ones

Seals - They also need proper sealings to stop back pressure

If properly done turbines can operate at high speeds and pressures and create good amounts of torque (that can be multiplied using gearboxes) and can be operated by electrical motors or can operate a electrical generator directly (often without a gearbox).

This makes turbines very powerful tools to have.

Turbines are also often very 3d printing friendly and can be very simple to design and use.

material science is important at high temperatures and when working with corrosive gases.

When working at lower temperatures, they can be much more forgiving.
