This is one briefcase that loves her tan. Simply open her up to absorb all the goodies that the sun throws at us and she will store enough in her built-in batteries to run a laptop for up to 6 hours, a small fridge for 4 hours and charge up 20 mobile phones at a time.

Obviously that kind of technology doesnt come cheap. Nor is it a briefcase that you can simply carry around from place to place. Looking kind of bulky (duh it weighs 10 kg), this briefcase from Strapya is the latest in a series of products helping us to go green.
