Solar Wind

Seen at our little harbour, which is rapidly emptying as the Autumn approaches. She is only a little boat, electric power, as IC engines are not allowed, So the owner doesn't arrive and find a flat battery, or they do not want to carry such a heavy thing back and forth, a Battery of Solar Cells on the cabin roof. 36 of them, what voltage they deliver I don't know, but must be considerable. The boat is so small and the Cells so large , you can use them as a sail on a cloudy day !
