A spring is one of the simplest devices for supplying mechanical energy. Springs are made of a material such as spring steel that returns to its original shape after being compressed, stretched or twisted. When deformed from its free state, the spring stores energy in the form of elastic potential energy, which releases when the spring is freed.

Springs for energy storage can be made of SWCNTs or MWCNTs arranged in dense bundles of long, aligned tubes called "forests" of CNTs [2] that are grown by chemical vapor deposition (CVD). The "forests" can grow to heights of up to 6 millimeters. [3] A deformed CNT requires a support structure to carry the load of the spring prior to discharge.

Spring-based energy storage is common in toys: jack-in-the-box, snake-in-a-can. I''ve heard of the opposite system - a concrete block on springs, say, a sidewalk paver in a busy city.
