The moment the fecal matter hits the rotating turbine, you can start shooting at people.

From playing with it, they learn some basic principles about fire, about intake, about combustion, about exhaust.

Number 13 was the test of the V12, plus exhaust and cooling system.

The exhaust pressure is controlled by a regulating valve to suit the needs of the process steam pressure.

The key to a practical jet engine was the gas turbine, used to extract energy from the engine itself to drive the compressor.

When a turbine is mounted on a rooftop the building generally redirects wind over the roof and this can double the wind speed at the turbine.

High temperatures are suitable for electricity generation using conventional methods like steam turbine or a direct high temperature chemical reaction such as liquid salt.

The best steam turbine at the time, invented by Gustaf de Laval, was an impulse design that subjected the mechanism to huge centrifugal forces and so had limited output due to the weakness of the materials available.
