The new innovative thermal trap can increase temperature to over 1000 degrees Celsius.

When solar light travels in the tube, the outcoming heat will increase the tube's outer shell's temperature. When sunlight travels in the channel in the hollow tube, the infrared radiation from the walls increases its temperature.

The heat trap can make it possible to create effective solar generators.

The new thermal trap can be an innovation for the steel industry. That system can decrease the steel industry's pollution. And it can make the solar-powered blast furnaces possible. However, the new thermal trap can offer the possibility to create effective power plants. The thermal trap can used to replace the fossil fuels on sunny days in the power plants. It can offer the choice to use solar power in the electric plant's boilers.

The solar generator is the tool where sunlight heats the liquid. And then the system drives this high-temperature and high-pressure vapor into the turbogenerators.

The heat trap is connected to the regular power plant's turbines. And it can boil water. The system can boil water in a closed cycle. That raises the pressure in the tubes. That system can also rotate turbines, and if that heat trap can be compact, it can used in ships and power plants.

The reason why we don't use steam turbines in the ships is that they are not economical. But if the steam turbines get their steam from systems that boil water using sunlight. That thing makes them ecological and economical to use. The sunlight using vaporization systems does not create emissions. And the turbines make ships very fast.

The high-temperature vapor with 500-1000 degrees Celsius can give a very good pressure for steam turbines. That thing can used in ships and power plants. So the next-generation ships can use solar energy on sunny days. And maybe the steam turbines are making a comeback. When the system creates vapor using solar energy. That doesn't cause fuel costs.

The heat trap can also make it possible to create a rocket engine, that uses sunlight to expand the propellant. The heat trap will heat the hydrogen or some other gas, that will travel back from the exhaust tube. And that thing makes an effective rocket system for traveling inside the asteroid belt.

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (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

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful. Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down. The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts. The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
