Think Hiin, Think!


Hiin is smiling, because I decided to try something out that I had read about earlier this (well, LAST) year...
...a clock with alarm capabilities, requiring no battery! Really-- it runs on water. Every 6-12 weeks or so, depending on the ion concentration in our tap water, the water has to be replaced; the energy comes from ion transfer onto electrodes on the back of the clock which are immersed in the water... Hiin really wants to figure this out; time for his Thinking Cap...
Think, Hiin, think!
