One of the oldest techniques people have used is falling weight. You lift the weight to store the energy in it and then let the weight fall to extract the energy. Many grandfather clocks and cuckoo clocks use this technique. By running the string attached to the weights through a gear. .
Many power plants use the "falling weight" approach in the form of water. The water is pumped uphill to a lake at night when the power plant has excess capacity. During high-demand. .
Another way to store energy is in some form of repeatable mechanical deformation. This is the idea behind a spring used in a wind-up clock or a rubber band used in a wind-up airplane. You store the energy by bending (deforming) the material in a. .
Another technique that nature uses to store energy is fat, which many of us are familiar with in a personal way. It is interesting to think. .
Nature has been storing energy for a long time, and if you want to think about it in this way, gasoline is really a form of stored energy. Plants absorb sunlightand turn it into carbohydrates. Over millions of years, these carbohydrates can turn into oil or coal. On a more. [pdf]
