Fruit-Powered Clock
A digital clock and calendar powered by food! The
Fruit-powered Clock ($15.99) combines micro-electronic technology with the natural electrical potential of a fresh fruit or vegetable. The clock uses the original scientific principles on which all modern electrical storage batteries are based. 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.
Water-Powered Clock
The epitome of a green gadget, the
Water-Powered Clock ($39.99) is actually powered by the very salt and water mixture that occupies 70% of the earth's surface. Without the need for batteries, the Eco-Friendly clock keeps perfect time as electrodes harvest energy from the water. All you have to do to make the clock run is fill its tank up with tap water and depending on the particles that are in your water system you may need to add a small amount of table salt. All that is required is changing or adding water and a dash of salt every 2 to 3 weeks. And the clock even remembers the time as you change the water!
Table Book Clock
The
Table Book Clock ($29.99) proves that not all fancy gadgets have to be obvious. This one masquerades as a set of books on a shelf. Fascinating design decision, don’t you think?
