H20 Multi Function Alarm Clock
Ecogadget has put together a list of Water Powered Alarm Clocks.
The one that stands out from the crowd is the unique H20 Multi Function Alarm Clock ($20) – running on a replaceable water-battery.
By just adding water you are providing the clock with an endless source of energy, never needing conventional batteries again! This clock also incorporates an innovative method for changing between modes – simply rotate the clock through 90-degrees to automatically change funtion from Time, to Alarm, to Temperature (F and C), to Coundown timer. The display automatically changes orientation with clever use of Newton’s gravitational theory!
