I read somewhere about a guy called Nikola Tesla, you might have heard of him. Apparently he patented technology that was later used in Logie Baird';s work. This Tesla guy apparently was a real genius inventor, a mad professor who wasn;t interested in commercialising his ideas. As a result a lot of his patents were bought out by the more famous people of that era for a pittance. Tesla was always desperate for money to pay for his latest project. One of his inventions was a means to transmit electrical energy from a transmitter (think aerial) to a receiver that could be miles away. He was successful with that but it never took off, not efficient and he only managed it due to some deal with the local generating company.
