Solar Powered Boat!

Okay, so it’s not exactly a gadget, but ‘Planet Solar’ is a hell of a boat. The fact that it is capable of circumnavigating the globe with nothing but the sun as a fuel source pays ample testament to just how efficient modern panels and battery management systems are becoming.

Despite measuring 31 metres in length and weighing 89 tonnes, a PV surface area of 516 square metres generates 93.5 kW, enabling this twin-hulled boat to cruise at around five knots with up to 60 people on board. How’s that for a glimpse into the future?
