we have all experienced that feelling of isolation when our phones run out of charge, and it can only be likened to haveing an arm chopped off.

but a new phone case could solve that problem for Iphone users, as a result of its ability to charge phone by harvesting electricity from the air.

nikona labs, who are producing the new case, have said that it can harvest 90 % of the energy wasted by iphone when connecting to wi-fi / bluetooth and acquiring a network signal.
