An idle couple of thoughts today as the sun finally made it up to 19 degrees. As my flower pot pond solar powered fountain had a busy day spurting away I got to contemplating the vagaries of the universe. If the sun did stop shinning we wouldn't know about until 6 minutes or so after the event - chilling thought.
Then I considered the solar equivalent to the philosophical conundrum regarding a tree that falls in a wood, if no one is present to hear it falling and crashing to the ground, does it still make a noise?
Therefore would a solar powered device directly powered by the sun, continue to operate until the end of time, whenever that might occur?
Hey ho, too much information so here's a picture of my pond:
