When I first started looking at the Bedol Eco Friendly Water Clock, which runs on nothing other than salt and water, I was told that it would keep time for a couple of weeks. In fact, it has kept excellent time for nearly two months and then slowly lost power. At first, the digital display started to flash and then the whole thing went dead. All it takes to revive the clock is to pour in some fresh tap water to the fill line. Oh, I did need to reset the clock to the current time, and it’s good for another month or more of keeping perfect time under its own power. On Bedol’s suggestion, I’m adding a little lemon juice to make the battery solution a little more acidic and more efficient.
