Just kidding, in fact I've a fair interest in this area. If wireless broadcasts can be made to provide sufficient power then I think we can do away with batteries all together, provided the broadcast is stong enough we could eventually see a wireless powered mobile, or laptop, but I guess that's some way off, but impossible.
In 1900, Tesla began construction on Long Island of a wireless broadcasting tower. The project was funded with $150,000 capital from financier J. Pierpont Morgan. The project was abandoned when Morgan withdrew his financial support. Tesla's work shifted to turbines and other projects, but his ideas remained on the drawing board due to a lack of funds. Tesla's notebooks are still examined by engineers in search of unexploited ideas.
