Abstract: A hydrogen-fired all-in-one electric generator/turbine that requires less rotational energy, substantially fewer parts, and less space in the power plant than traditional designs. The turbine is embedded within the rotor, each sharing a common, shaftless axis of rotation, and as a result, reduces the overall weight and size of the turbine/generator. The electric generator is energized by an energy capture system that captures the heat and thrust produced from a hydrogen and oxygen reaction. This is accomplished by means of heat exchangers and turbines, as well as the aforementioned generator/turbine. The system is intended to replace steam generators that rely on fossil fuels and uranium and used in electric power plants. These power plants will be able to install more generators in the same amount of space. More generators operating at higher rates of rotation will significantly increase the electric power generated.
