Big green energy machines - The Industrial Physicist

Big green energy machines - The Industrial Physicist: "A more developed design might circulate oxygen and add methane when needed by local injection to make expansion almost isothermic. Dual cycles, maximum capacity, and changes in temperature in the regenerator with such dense gases all need to be imaginatively considered by physicists and engineers in a grand concourse of designs.

Fortunately for transmitting mechanical power, the high pressures shrink the machinery in a revolutionary way and so permit the turbine to rotate very fast. The generator could then also turn very fast, operating at high frequency, and appropriate power electronics would slow the generated electricity to 60 cycles."
