Beam me up, Charlie

Delegates at the World Future Energy Summit in Dubai were shocked when a full-sized hologram of Prince Charles appeared to lecture them on climate change.

The Prince, who's come under fire before for his 'do-as-I-say' carbon footprint, decided not to fly to the conference, because jetting over there with his entourage would have produced 20 tons of CO2. Sadly the rest of the conference had all flown there to see him, but it's a start, I suppose.
