FLYWHEELS VS. BATTERIES
FLYWHEELS ARE ONE OF THE OLDEST MEANS OF STORING ENERGY. CAPABLE OF DIRECTLY STORING AND REGENERATING OVER 90% OF INPUT MECHANICAL ENERGY, WHEREAS BATTERIES ARE A SLOW CHEMICAL PROCESS AND SUBJECT TO THE “ USE IT OR LOSE IT”  PROBLEM OF ALL ELECTRICAL DEVICES IT CAN ONLY RECHARGE  SLOWLY REGARDLESS OF AVAILABLE INPUT ENERGY.
 FLYWHEELS NEVER WEAR OUT, WHERE BATTERIES HAVE A KNOWN COMPARATIVELY FINITE LIFE SPAN.
 BATTERIES ARE BULKY AND VERY HEAVY, WHEN APPLIED TO AUTOMOBILE USES, THEY REQUIRE THE ADDITIONAL WEIGHT OF A CHARGING GENERATOR THIS ADDED WEIGHT DETRACTS SIGNIFICANTLY FROM THE GAS MILEAGE. THE NELSON/TYWA FLYWHEEL POWER PLANT ACTUALLY REDUCES THE GROSS WEIGHT OF THE VEHICLE, ADDING TO ITS ALREADY SUPERIOR FUEL EFFICIENCY.
