The scorching UAE summer is reaching its peak, as cooler countries across the world experience unprecedented temperatures. For those feeling the heat, Sony has come up with a solution: a wearable air-conditioner that fits inside your pocket. The Reon Pocket, which has been created by the company's startup acceleration programme, is a small device that slips into the back of a specially designed shirt, right by your neck. And it can keep you cool – or warm, if needs be – at the touch of a smartphone. It is said it will be able to cool a user's body temperature by 13 degrees celsius or raise it by about eight degrees. It works with a rechargeable battery and the temperature can be adjusted with a smartphone via Bluetooth. The shirts come in a men's size small, medium or large (no word yet on one for women) and prices for the device plus the garment will start from about 12,760 Japanese yen (Dh432). The device's battery will last for 90 minutes after a charge of two hours. Sony is currently crowdfunding for the project, and if all goes to plan the device should be available by around March 2020, although the company only has plans to release the Reon Pocket in Japan for the time being.
