Sunlight Energy Storing Chemicals
Photodimerization is the light induced formation of dimers. As early as 1909, the dimerization of anthracene into dianthracene was investigated as a means of storing solar energy. The photodimerization of the naphthalene series has also been investigated.
Photoisomerization is the light induced formation of isomers. Various ketones, azepines and norbornadienes among other compounds have been investigated as potential energy storing isomers. The norbornadiene-quadricyclane couple is of most potential interest for solar energy storage processes. The controlled release of the strain energy stored in quadricyclane (about 110 k J/mole) back to norbornadiene is made possible. Also, many different derivatives of norbornadiene has been investigated for this reaction.

Famous quotes containing the words sunlight, energy and/or storing:
“Just across the Green from the post office is the county jail, seldom occupied except by some backwoodsman who has been intemperate; the courthouse is under the same roof. The dog warden usually basks in the sunlight near the harness store or the post office, his golden badge polished bright.”
—Administration for the State of Con, U.S. public relief program (1935-1943)
“The scholar may be sure that he writes the tougher truth for the calluses on his palms. They give firmness to the sentence. Indeed, the mind never makes a great and successful effort, without a corresponding energy of the body.”
—Henry David Thoreau (1817–1862)
“Computers are good at swift, accurate computation and at storing great masses of information. The brain, on the other hand, is not as efficient a number cruncher and its memory is often highly fallible; a basic inexactness is built into its design. The brain’s strong point is its flexibility. It is unsurpassed at making shrewd guesses and at grasping the total meaning of information presented to it.”
—Jeremy Campbell (b. 1931)
