We are talking about, then , maybe 392.1 attowatts !!!  |
Hi Max,
Yes, you are right. I made a mistake calculating square meter when I should have converted from square Km. Much less power in a square meter.
But some people have actually extracted usable power from the air. Nicola Tesla, for example. He powered a car from energy extracted from the air using an antenna, causing the car to travel easily to 90 miles per hour with an electric motor. He also put usable power in the air that caused fluorescent lights to light up 20 miles away.
Best wishes,
