My idea is to create a sphere of sustainable plasma using a vortex style reactor. The Sun's fusion happens at the core in an
extremely hot and dense spinning ball of super heated hydrogen. That combines to form helium, releasing tremendous heat and energy. My idea is a spherical shaped reactor with rotating magnetic fields that trap the ball into the center of the magnetic field and by spinning and contracting, you feed hydrogen in through the top and exhaust the heat out the bottom. The super heated gas can then be fed into a turbo styled turbine. Whereas little to no thermal heat energy will be lost, by using graphene and hydrogen layered housings, pipes, and other thermal areas. The exhaust piping would also be protected with a series of electromagnets, thereby trapping the heat in the center of the pipe, without ever really touching the sides of anything.
