Totally Geeky or Geek Chic? Fruit Powered Clock

Little known fact: A professor of physics at the University of Pavia in Italy, Alessandro Volta (1745-1827) is credited with the invention of the electric cell. He stacked a zinc disk and a copper disk, with a leather disk in between. The leather disk had been soaked in a mild acid solution of lemon juice. Volta found that a small flow of electrical current between the copper and the zinc resulted. Thus was born the 'voltaic pile' or electrical storage battery.


The Fruit Powered Clock, $14.95, essentially replicates this experiment. Just add a fresh orange, apple, lemon, lime, pear, banana, or any another convenient fruit or vegetable to the supplied components in this kit and you have the perfect synthesis of nature’s own electrical power resource and the accuracy of a digital clock.

You can get a solar powered clock for the same, can't you? Without the fruit flies? BaltimoreGal
