This technology was developed by Tesla long time ago. Tesla invented the electricity and also microwaves but somehow history is manipulated for that case. He said that he can lighten a city without cables but some companies didn't like his idea financially. He was killed misteriously.
Edison is used to be a photographer at the day time. And at the night time he was taking nude indoor pictures for rich men. He was taking these pictures at home cause it was totally unacceptable at that time and he had to keep it secret. He needed strong light for better pictures. That's how and why edison invented the lamp. Just foor boobs.
