Scientists have sounded the death knell for the plug and power lead.
In a breakthrough that sounds like something out of Star Trek, they have discovered a way of ‘beaming’ power across a room into a light bulb, mobile phone or laptop computer without wires or cables.
In the first successful trial of its kind, the team was able to illuminate a 60-watt light bulb 7ft away.

It sounds effective but is it efficient? We don’t need to have to build a grazillion new power plants. I can envision power losses in high percentages. If it broadcasts all the time, then what happens when there is no use for it. A lot of questions between here and declaring the end of power cords. Also, who pays? Every guest charges his cell phone at my expense? Sounds like we need some nuclear reactors. Another great technology sidelined by popular ignorance. (France get 2/3 of its electric power from nuclear reactors.) So there is often a lot of resistance to new ideas.
