Arriving at the woodlot, he parks the cart in the sun so its on-board panel above can soak up even more energy than is already stored in its 10 KW hour battery pack which supplies a 2,500 watt, 120 volt inverter. He easily lifts his six-pound electric chainsaw and connects it to a 150 foot extension cord plugged in to the cart. The cord trails behind him as he walks into the woods and up a rise. He pushes a switch with his thumb and the chainsaw roars, or more accurately, purrs to life. Within a minute the tree gives way, falling neatly.
