By analogy, it’s like the difference between having an engine and a set of wheels on one hand and a car on the other. Only with a car do you easily and comfortably enjoy the benefits of the combustion engine and likewise, only with the PowerTower can you enjoy easily and cost effectively the benefits of energy storage: reduced electricity bills, no-noise and always-on backup power, efficient hybrid ba
