Magnet-wobble wireless charging system dishes out a respectable 10 kW

Canadian wireless power company Elix has announced a system which can generate and transfer 10 kW using magneto-dynamic coupling.

How practical is an electric car in London?

Comment If you revel in the independence a car gives you, then electric is not for you. The quoted range of 100 miles (161km) sounds fine, but that's a bit like a quoted ADSL speed. Your mileage may vary. The truth is that if and when the car goes flat, you are in deep doo-doo. Run out of petrol and you can walk to a petrol station, …
