The deformation of elastic springs is one of the oldest and best-known forms of energy storage. The advantages of mechanical springs over other forms of energy storage include high reliability, durability, and efficiency. Although mechanical springs are typically used to power clocks and wrist watches, new advances have led to mechanical springs as a means of powering electronic devices such as vehicles and radios. However, mechanical springs exhibit low energy storage density. Energy storage devices based on the mechanical deformation of Carbon Nano Tubes (CNT) are in principle capable of much higher energy density than any known chemical battery. Moreover, CNTs also have the potential to be more efficient and to have longer lifetimes than chemical batteries. Therefore, this technology will be able to store greater amounts of energy and subsequently use that energy for practical purposes such as powering machinery or electronic devices.
