Holographic tours to help the planet

Serj Tankian, the frontman for Los Angeles rock band System of a Down, is so dedicated to saving the planet that he wants to launch a virtual concert tour to reduce his carbon footprint.

"I've had an idea for a long time, which might sound a little crazy, but I really want to look into holographic touring," Tankian told Billboard.

"I think we could reduce our need to travel if we could project ourselves into meetings and concerts. We have the technology, and we're not using it right now."
