Supersonic Aircraft will Use Rocket Engine in the Future
We've heard that this aircraft can bear passenger capacity of 50 to 100, and before the airplane fly, we should use the original biological fuel engine to promote it, and after it get to a certain height, we'll then change to use hydrogen and oxygen rocket engine to promote it, and its height will get to 32 kilometers that more over the height now.
When preparing to down land, this aircraft will turn off the engine, and then slipping slowly to the ground, it will restart the original engine when we get close to the earth surface.
The European Aircraft Company will cooperate with Japanese researchers to develop this new aircraft. Using existing technology to research and develop this supersonic aircraft, and they hope to be able to develop the prototype in 2020.
The developer said that: "We think that all aircrafts won't make any pollution just like Zehst. They can fly in the stratosphere all the time."
As we know, RC gasoline engine aircrafts will produce a lot of pollutions when flying in the sky. Pollutions caused by aircraft flying in the stratosphere are mainly from the burning of fuel exhaust, such as carbon dioxide, carbon monoxide, not burning hydrocarbons and particulate matter, nitrogen, etc. In addition, aircraft will also produce noise pollution. Condensation trail refers to the "white smoke" for the speed of flying. It is made by the water vapor in the air and exhaust fumes in the air condenses into ice crystals. Studies have found that condensation trail can form a roll cloud (a high-altitude cloud).This cloud will hinder the loss of heat radiation from the earth's surface, thereby contributing to global warming.
So the coming of the supersonic aircraft of "Zehst" will reduce the pollution produced by the airplane, and can also bring us a fresh environment. What's more, I also hope this model RC airplane of this mode will come soon.

Google Maps Get Update for iPhone & iPad!
On July 17th, 2013, Google announces they have updated Google Maps for the iPhone and iPad. This updated also incorporates many new features from its newest Android system.

Study Finds Danger in Using Laser Pointers Too Much
Presentation laser pointers have make our life more convenient, but there is some bad thing happened with the coming of this cool gadget.
For example, in the preliminary contest of European championship2011, England's player Tony Parker was into a disturbance by the laser pointer. And early in 2008, Lyon fans irradiated Cristiano Ronaldo's face with a laser pen for many times, so that has triggered strong protests from Manchester team.
However, there are still some people who use the laser pointer to harm the fly of the plane in the night. In fact, the dangerous of laser pointers are stronger than you though. Because once if the laser pointers was exposure in the pilots who driving absorbed, consequences cans be imagined; And take-off and landing stage itself is a high incidence of accident at that time, if the pilot encounter interference by the powerful light, the situation will become more dangerous.
Besides, laser pointers can also hurt our eyes without a good use. Looking into the laser power of 5 mw and above will cause temporary vision damage to eyesight; the more powerful will cause permanent eye damage or even blindness.
What's more, high power laser may ignite flammable and cause a fire. Some high power laser pointer, diffuse light may also cause harm to the eyes, focusing more likely fire on the flammable items.
But not all of the laser light source will cause harm to our eyes, once we've taken the appropriate protective measures, as long as there is some protection in the process of operation behavior, then this type of damage is very small. Here we suggest all of our friends to use laser pointers in a reasonable way to avoid hurting from it.
