For many years we have depended on fossil fuel to play the main role in our transportation and therefore it affects our economy. The future should not have these old fashioned engines which kill us very slowly with their harmful emissions.

The idea is an engine which operates depending on the Meissner effect, which is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state, and this effect has been used in our life in so-called magnetic levitation.

How it works!!

Nitrogen liquid goes through the main rotating hollow shaft and then inside the turbine blades in order to bring it to its critical temperature at which it will be superconductoring. At this moment the magnetic flux which is coming from magnetic discs as shown in the figure, can not be able to go through the blades and then it will generate a force on the blades which will cause a torque and energy on the shaft.

The gas will go in, with temperature T1 and get out with T2. Obviously T1f rotating could be used in maglev trains in order to speed it and control it too. Depending on many calculations, it will be efficient and give a sufficient power source in order to do its task.
