Economics 101 -- generate more revenue capture more energy
The kinetic battery can only do this because it is installed directly between the turbine and generator. Because other energy storage mechanisms occur after the generator has converted the rotary-kinetic energy into electrical energy, those technologies are not capable of capturing this “lost” energy.
What makes this product superior
The battery uses two continuously-variable-transmissions on either side of the battery to vary the gear ratio between the turbine and generator shafts. This in turn varies the inertia of the system. This variable inertia mechanism allows energy to be stored in the flywheel as kinetic energy while maintaining the desired speeds of the input and output.
The PKE solution may make your current project 30-50% more profitable and may make a future project without subsidies economically viable.
