Induction can create an electric current over a 'small' gap. See for example http://en.wikipedia.org/wiki/Inductive_charging.

Also electromagnetic waves contain energy and can therefore be used to create electricity at a distance. This is used in some ideas for space based solar stations, where they use microwaves to transfer the energy from space to the earth.

No, We can generate it up to a larger extent which is already been pointed out by @Laar but its efficiency would be too low for commercial power transmission... –  Waffle's Crazy Peanut Aug 21 '12 at 13:26
