Some food for thoughtA universal phone charger-just approved by the International Telecommunication Union-isn't being forced on cell phone makers but rather recommended. But what companies wouldn't implement the charger, which has a micro USB connector, energy efficient technology, and would cut 51,000 tons of redundant chargers a year out of the waste stream?On that note, we're all juiced up over a socket that could easily and seriously cut phantom load, or vampire power.
