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:
“Love is the hardest thing in the world to write about. So simple. You’ve got to catch it through details, like the early morning sunlight hitting the gray tin of the rain spout in front of her house. The ringing of a telephone that sounds like Beethoven’s “Pastoral.” A letter scribbled on her office stationery that you carry around in your pocket because it smells of all the lilacs in Ohio.”
—Billy Wilder (b. 1906)
“Long before Einstein told us that matter is energy, Machiavelli and Hobbes and other modern political philosophers defined man as a lump of matter whose most politically relevant attribute is a form of energy called “self-interestedness.” This was not a portrait of man “warts and all.” It was all wart.”
—George F. Will (b. 1941)
“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)
