Spring Power Forever It’s quite the trend to look for ways to extend the life of a battery, be it a AAA, AA or even the D-size. What we have here today is the ONE=TWO – Spring Battery. The design is quite self explanatory, so my question for you today is this: is it worth extracting every ounce of juice from discarded batteries in comparison to the production of such extracting devices? What do you say….. One = Two is a 2011 red dot design concept winning entry.
