Question

does a piece of paper have energy?


Proper answer..

Answer 1

collaboration between three labs at R.P.I.—biopolymers, nanotubes and electronics—the power paper works by using cellulose to separate aligned carbon nanotubes functioning as electrodes. The nanotubes are grown and the cellulose is dissolved in an electrolyte—in a regular battery (sulfuric) acid is used, but in this case a room-temperature ionic liquid (otherwise known as a liquid salt)—is poured around it. After drying, a thin sheet of "nanocomposite paper" is left that "can be rolled up, twisted or bent to any curvature," the researchers write in Proceedings of the National Academy of Sciences USA.

Answer 2

Answer:

The paper still has energy – it is just not using it. Science classifies energy into two categories – kinetic (moving) and potential (stored) energy.

Energy can change between potential and kinetic. Water at the top of a waterfall has stored potential energy but as the water begins to fall, it changes from potential to kinetic energy. It is this process that we utilise when we create energy from hydropower – we harness the kinetic energy of the water for our own use
