Battery Breakthrough
No one will every invent a battery lasts forever without recharging but one day a battery that lasts a really long time will hit the market. When that day comes, the Internet will definitely step up to the next level.
As is the case with so many other technological breakthroughs, the next-big-thing in batteries might be the result of a military application.
Until then, don’t stray too far from an electrical outlet.
