New idea: solar panels that condense water from the air. The same systems can also be used to clean air in city areas.

Researchers in Saudi Arabia developed a new technology that keeps solar panels cool and collects water from the air. The idea is that there is a component in the middle of the V-shaped solar panels. When high-temperature air rises from the sides of the V-shaped structure the cooler air will fall in the middle of the structure. The wall or element causes condensation that condenses water from the air. That kind of system can be useful in the hot deserts. And maybe they can collect water from the air in many other places.

Water collectors can also clean air from the cities. Especially in summertime, the air is full of vapor that involves lots of pollution like toxic compounds and dust. The water collectors can remove those polluted droplets from the air. And those systems can also produce clean energy.

The air is filled with vapor or miniature droplets that tie the pollution like dirty dust. When the condensation system removes those droplets from the air it cleans air too. Then that dirty water must be put somewhere or the pollution is recycled into the air. Then system must conduct condensation water treatment plants. Without a cleaning process, polluted water can increase pollution in water.

The condensation walls can also used to keep humidity at the right level in houses.

Computer centers can use similar water collectors to keep their air dry. The system requires electric heaters that can work inside buildings. The thing is that the air dryers can be used to clean the air in buildings.

Then the system must just remove the vapor from the air and that kind of system can also used to make the houses more comfortable if the air is too humid which brings fungi and bacteria into the rooms. Computers don't like humid either. And if the air is too dry, it's not comfortable. The system can inject water into the air if it's too dry.

The problem is: how to remove water from the air if the humidity rises too high. But if we want to adjust the humidity in the air. We must put the vapor somewhere. We can raise the temperature, but the high temperature makes rooms uncomfortable. And high temperatures don't remove humidity.

MIT's tractor beam can make the new types of SASER systems possible

"This chip-based "tractor-beam," which uses an intensely focused beam of light to capture and manipulate biological particles without damaging the cells, could help biologists study the mechanisms of diseases."(Interesting Engineering, MIT’s Star Wars-inspired ‘tractor beam’ uses light to capture, manipulate cells) MIT's tractor beam can make the new types of SASER systems possible. The tractor beam just hovers the nanoparticle in air or medium, and then the laser or some other electromagnetic system transports oscillation into those particles. The ability to make cells and other particles hover in the system makes it possible to create particles whose energy level or resonance frequencies are accurately calculated things. That thing makes it possible to create things that transmit wave movement accurately and cleanly. This is one version of the use of a tractor beam. Modern tractor beams are like acoustic tweezers where sound waves lock the object in its cr

The new observations tell that the thunderstorms form gamma-rays. That could make gamma-ray lasers possible.

That could make gamma-ray lasers possible. The process has been observed by the NASA (Lockheed) ER-2 research plane, which is a modified U-2 spy plane. The gamma-ray formation in thunderstorms. Where lightning and electric fields release electrons that impact the air molecules and water droplets is an interesting thing. That thing opens the route to solving many mysteries. "The general physics behind how thunderstorms create high-energy flashes of gamma radiation is not a mystery. As thunderstorms develop, swirling drafts drive water droplets, hail, and ice into a mixture that creates an electric charge much like rubbing a balloon on your shirt. Pos

Chinese innovations and space lasers are interesting combinations.

(Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th
