That is a very cool mower, but I did not see the price... I take it its like my Dad always said, "if you have to ask the price, you can't afford it." I'm glad I don't need anything that big and that my little corded GreenWorks mower covers my needs in Indy just fine.
But while reading this old thread I checked out the AMG Electric boat
that hill mentioned years ago. I was thinking there is no way an electric boat would ever be viable -- as unlike a car, a boat never coasts with the water as a constant drag. So while that baby may may have over 2000 hp, it also weighs about 5000 lbs. and the devil is in the details "The boat has two chargers providing a total charging rate of 44 kW, taking about seven hours for a full charge....This means that the batteries can only provide full power for about ten minutes." Now it might be a great 10 minutes, but even at half speed this baby won't get you very far on the water and if you think being stranded on the street is bad, try the middle of a lake.
Still a fun thought
