Some of you might remember that Eco-Friendly Water-Powered Clock that was covered here at GeekAlerts last summer. This new model takes it one step further by allowing you to power the timepiece with just about any liquid – yes, even beer.
No batteries are required to power this futuristic clock. Fill it with any liquid – water, juice, milk, even beer – and it will keep accurate time and date displayed.
The Mini Hydro Clock is available from the Edmund Scientific website for $7.95.
