In building drones that kill people, the US has a couple-decade head start on China. But when it comes to domestic uses, US businesses are hamstrung because the Federal Aviation Administration (FAA) isn’t required to issue commercial drone rules until 2015. In the meantime, one of China’s biggest delivery companies is tinkering with using drones—with Chinese government permission.

SF Express is testing a drone it has built for delivering packages to remote areas, according to Chinese media reports. The drone can hit an maximum altitude of 100 meters (328 feet) and deliver parcels within two meters of its target. It’s not clear what sort of weight these puppies can handle, but Beijing journalists calculated that it probably can’t carry more than 3 kilograms (6.6 pounds).
Stopping and accelerating again at each station will waste both energy and time. But in this brilliant new Chinese train innovation No time is wasted- get on & off the bullet train without the train stopping. The bullet train is moving all the time.
A mere 5 min stop per station (elderly passengers cannot be hurried) will result in a total loss of 5 min x 30 stations or 2.5 hours of train journey time!
How it works (view the movie):
1. To board the train : The passengers at a station embarks onto to a connector cabin way before the train even arrives at the station. When the train arrives, it will not stop at all. It just slows down to pick up the connector cabin which will move with the train on the roof of the train.
While the train is still moving away from the station, those passengers will board the train from the connector cabin mounted on the train’s roof. After fully unloading all its passengers, the cabin connector cabin will be moved to the back of the train so that the next batch of outgoing passengers who want to alight at the next station will board the connector cabin at the rear of the train roof.
2. To get off the train: As stated after fully unloading all its passengers, the cabin connector cabin will be moved to the back of the train so that the next batch of outgoing passengers who want to alight at the next station will board the connector cabin at the rear of the train roof. When the train arrives at the next station, it will simply drop the whole connector cabin at the station itself and leave it behind at the station. The outgoing passengers can take their own time to disembark at the station while the train had already left. At the same time, the train will pick up the incoming embarking passengers on another connector cabin in the front part of the train’s roof. So the train will always drop one connector cabin at the rear of its roof and pick up a new connector cabin in the front part of the train’s roof at each station.
