I don't really buy the notion that "Japanese high tech production moved to China making China's high tech export increase".

Haven't we heard a lot about Japanese companies moving out their investment/production from China not long ago? These statements made headlines since the east China sea friction began and only faded out in 2015.

If these statements tell the truth and they must be because they were primarily made by western and Japanese medias ;), they must have suggested that the increased Chinese high tech export is made by real Chinese high tech products.

It would be interesting to actually see the detailed break down of product in catagories and brands.

According to what I read, in that statistic there are four tech catagories. High, Mid-High, Mid-low and Low. When talking about high tech export, I believe we are talking about the two first catagories only.

Here is my analysis. High-end Japanese products such as DSLR (I think it would be counted as middle-high tech) are mostly made in Japan, check your Canon 5D, 1D, 7D etc if you don't believe me. Japan only moves mid-low production abroad, check your Canon Ixus, SDxxx. Note, car is only mid-high. High tech is something like nuclear power plant, medical electronic equipment, high-speed railway, aircraft, gas turbine engine, hydrolic power plant etc. I don't know any Japanese brands of these products are made in China or anywhere else. Let me know if someone has a better idea.

I think it is time for people to stop taking credit from others and face the reality that China is surpassing. History is our best reference. Just look at Germany in the early 1900s, Japan in the 1960 and 1970s. Anyone tries to take the credits from them today?

The Chinese startup company Ehang unveiled yesterday at CES what it claims is the first passenger drone, capable of carrying one person for about 20 minutes. According to

: "The cabin fits one person and a small backpack and is fitted with air conditioning and a reading light. It is designed to fit, with propellers folded, in a single parking spot." The company hopes to sell the device for $200,000 to $300,000 (£140,000 to £200,000) later this year.

(AAV) weighs 200 kilograms (440lbs), and has four sets of paired electric motors. The company claims the batteries can be charged in two to four hours. The drone is controlled via a tablet, which is used to set the flight path before take-off. According to the company's website: "Ehang 184 AAV flies in a inverted U shape. It takes off and lands vertically, point to point direct flight based on altitude and latitude of the origin and termination point. Take Off/Landing points are landing targets pre-set with Ehang Logo. The landing camera will position the landing targets automatically and accurately."


Since the passenger has zero inflight control over the machine, safety is naturally a major concern. The company claims: "Even with one propeller malfunctions, it can still land in the nearest possible area safely." In addition, if any other components malfunction or disconnect, "the aircraft will immediately land in the nearest possible area to ensure safety."

According to The Guardian, the company also says it is planning to set up a remote control centre that would take over the vehicle if there were a problem.

. The Ehang 184 represents an ambitious extension of its activities beyond these smaller, traditional drones.

At a time when authorities around the world are clamping down on the use of unmanned drones, it is not clear how one that carries passengers will be received. Unlike for autonomous cars, which are gaining wider acceptance, the margin for error with autonomous flying vehicles is rather small. Nor is it obvious who might want to buy and use such a passenger drone.




This company goes from a toy drone maker to a full fledge flying passenger transport maker. Would you trust them? I don't know. One Youtube comment says "Nothing about this thing look safe to me especially with it being low altitude. With eight blades to contend with, it looks like a human salad maker with red dressing....."

What's most interesting is that they have ACTUALLY test-flight this with people inside the craft several times, and this doesn't look like a vapourware like that Moller Skycar M400 which has been in development for well over 40 years and still have nothing to show for.

Is it still technically a drone if it carries a passenger?

I notice there are actually 2 (counter rotating) electric motors on each of the four ends, meaning that there is always one backup motor to do the emergency landing when one of the pair failed. It can probably be used too as a heavy duty UAV, transporting goods?
