sketch from an article in the 69. issue of Pist Protta magazine Reaching the Sun by Sea is based on the presumption that a specially designed boat could actually reach the sun by sea, using solar power to drive and navigate it. This unmanned boat is equipped with solar panels facing starboard and port and two motors running propellers on either side. Each panel supplies the motor on the opposite side with electricity. Thus, the boat will always steer towards the sun.
