Wernher Von Braun, and using empty rocket stages as the revolver-shape space station.

(Picture 1)

Kimmo Huosionmaa

There were stories, that legendary Wernher Von Braun planned cheap space-stations by using the empty rocket stages. Empty rocket stages would send to the orbiter with other launches. And that would make the station very cheap. The needed gasses, what are actually the pressurized air, would be packed in the bottles. If the used gas would be pure oxygen there would be the risk of fire in that space station would cause the explosion. The station would be built in the Lagrangian point near Moon, where it would need no fuel to stay in right position.

But von Braun didn't mention that this kind of space station would have more capacity if the stages have assembled in the form of the revolver cylinder, and the stages or modules would be set in like patrons of the revolver. This shape would allow getting the space station as the rounding situation, what would make the synthetic gravitation possible. The picture above the text is an artist impression of same style space station but in Von Braun's original idea the cylinders were installed lengthwise and the number of the cylinders or empty rocket stages was three or four.

If the modules would put in the body like the patrons have put in the revolver, the small size "artificial world" could be possible, and if the space station can grow the food inside its core, the system could work independently. And because of the independently produced food, the service flights must not make so often. The use of empty rocket stages would be helpful to keep that project in secrecy, and in the real life, those empty stages would be pulled to the right point by using small spacecraft like X37B.

This kind of modular space station could be very effective for any kind of missions on the space. The artificial gravity and the electromagnetic shields would make the astronauts allow stay very long time in that station, and they will not get any weaknesses or cancers in the staying at the station. That would help cover the existence of that space station.

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.

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
