Ditch batteries altogether, and run this digital clock on water. Yup, water (and some lemon juice). This green-friendly clock uses its built-in electrodes to sip whatever power it needs from the acidic water.
Just one caveat – you need to change the water every 5-7 weeks. Seems like a small price to save landfills from batteries. Comes in 4 different colors.
Wicked cool. I’d just like it to include an alarm clock, but I’m guessing the power requirements for that are too high for mere lemon water to meet.
