Holograms to reduce energy use substantially

I read that Forever 21's Hologram Fashion Show Comes to the U.S. This is a show which replaced live models with holograms. It was first presented in Vienna (Austria) in May and then in Brussels and London. Think about the energy which can be saved if 20-30% of the business trips around the world are replaced with holograms. Meeting my Chinese business colleagues could be done initially in a conference room which makes us all feel that we are in this same room, independently if some of the participants are being represented by their holograms. In the future, the technology could be improved and the same could done in the personal computer.
