Solar-powered boat

It might look like a cheap pedalo but that canopy you see in the picture is in fact a solar panel. Safe, clean, quiet, effortless to operate, virtually-maintenance free, and requiring minimal nautical knowledge, this boat is capable of ferrying up to 4 adults. Its ergonomic seats promote pure relaxation while the 700-watt electric motor moves the craft silently through the water at a cruising speed of 5 mph. The motor is powered by four deep cycle batteries that are constantly recharged by the sun during daylight hours-even when it is overcast. The boat can be purchased  from Hammacher Schlemmer  (although it is ‘out of stock’ at the time of writing).
