It's comical how no one seems to realize this. People see electricity as clean energy and give no thought what so ever to how it is being produced
CBOX, try not to let yourself get to the point of throwing the baby out with the bath water. Electricity IS clean energy. What it is generated from is a whole nother issue. Whether you charge a battery with coal or solar cells doesn't change how clean or dirty an electric motor or a battery is.
Back in the recesses of my mind I can hear Orville making your point to Wilbur... "Maybe we shouldn't.....This thing could wind up crashing and hurting somebody."
Or why da Vinci's invention never left the drawing board.... "Forget it. This thing could wind up screwing up the air."
Electric systems need to be developed. Sikorsky Inovations may have said "Lets hold off" but someone else said "Lets go for it!"
