The Water Powered Multi Function Clock. £14.95. Interesting design uses an H2O battery which you refill with water every couple of months. Hmm…spit and tick. OK, moving right along…
This clock boasts a range of functions that are accessed by turning the clock through 90-degree turns: time, day and date; alarm settings; countdown timer; temperature. To keep the battery going, refill it as the water evaporates typically every 2 to 3 months (the battery will last a minimum of 2 years with continuous use).
all run 100% from simple tap water; no batteries, plugs, or coal-powered engines! It’s just one step you can make in reducing your electricity consumption.
