Lightpipes have been around for a while and you can pick up versions in Home Depot. The difference is this system sending the visible light throughout the building, and splits the IR off and sends it to a PV cell. Since the light is already concentrated, the total cell area is small and the efficiency is good.
And you will seriously believe anything that comes from Xinhua as reality? There was a popular news show in Taiwan that would compare news from Xinhua with what was happening in reality. It was really quite amusing.
Remember the SARS epidemic? I think Xinhua said three people in Beijing were initially thought to be infected. They must have been an important three people because school was cancelled for a month and Beijing was a ghost town.
Pilots are paid a lot because of their job is, umm, slightly more important than the guy who does the final coffee maker check. They have the final say on whether the plane is fit to fly and it's their responsibility to keep their passengers not happy, but alive. There's no nodding off for a few minutes while the boss is in a meeting.
