First Flight is Sony’s new crowdfunding program. The last arrival on the platform is a personal AC, which doesn’t blow processed air on the body, but slot into the back pocket of a specially designed T-shirt and uses thermoelectric currents to provide cooling – by 13 degrees Celsius –, but also heating. A full charge can make this small device, which weighs not more than 3 ounces, last for 24 hours. The project is already fully funded, with the price of a single unit starting from around €100, but for now Reon Pocket at the moment is only be available in Japan.
