Claire's Eco Store features the Atomic Clock. Being powered by a splash of water and a dash of salt, the water powered clocks keep perfect time with no need for any batteries. Sounds like magic?! It’s just simple science and is a great educational timepiece for children (and adults). The water powered clock uses in built electrodes to harvest energy from the water. This is a clock that improves the environment, both inside and out. Below is a review of the Atomic Water Powered Clock:- 'I was sent a water powered clock to my home. I filled it up expecting a very weak display if anything. It took about 3 minutes for the electrolytic reaction to start and for electrons to flow but that was over a month ago and since then I have not had to replace the water so either our local water is an extremely rich electrolytic fluid or the 2 weeks running time between refills, mentioned in the instructions, is very conservative. The display is very clear with large (about 3cm tall) clear very dark LCD digits. I also like the fact that the shape of the clock coupled with the weight added by the water makes it very stable. In terms of its aesthetics it is more suited to either the kitchen or bathroom or perhaps a child's bedroom. If I was to have selected one myself I would have bought the one that includes a thermometer but apart from that, so far, this clock has far more pros than cons.' With the world finally coming round to the fact that renewable energy is a not only a good idea but could really make a difference, the Water Powered Clock is an ideal way to make your eco friendly contribution. The water powered clock needs very minor upkeep and only includes topping it up and adding a splash of lemon juice. This will ensure the Water Powered Clock is good for around 6 weeks of timekeeping. Not only that, it's an awful lot cheaper than constantly stuffing it with AAA batteries. Best of all, you won't even lose time while changing/updating the water, thanks to the built-in memory chip! In summary the Water Powered Clock is cool, environmentally friendly, suitable for all ages and perfect for the office or at home. At a surprisingly low price this clock is a great gift item for friends and family. Claire’s Eco Store sell large quantities of Water powered clock and always hold stock of these.
