A new aircraft engine?

It's called the Fluidic Propulsive System. (FPS), means the "fluid propulsion system", or perhaps rather the "fluid-based propulsion system", or actually "fluid physics". In fact, it is not a liquid, but a gas, quite simply air, which from a physical point of view can also be viewed as a very low-viscosity liquid.

Andrei Evulet from Romania, who has 15 years of experience at GE Aviation, has been building prototypes of these engines for some time. He was responsible for the technology that is part of the world's largest jet engine, the GE9X, which is working on the Boeing 777X. Together with his school friend Denis Dancanet, he founded Jetoptera a few years ago. They were guided by the idea of ​​creating a new propulsion system that would be ideal for VTOL's vertical take-off flights and that would enable both large unmanned drones and flying cars to be used.

The Star Wars Light Plasma Sword has become a reality

The well-known Hacksmith Internet DIY team of hackers, who translated various concepts from films, comics and games into real devices, constructed a "real", ie plasma-based lightsaber. Although it is not as comfortable as the weapon from "Star Wars" because it unfortunately requires a thick gas supply cable, it looks quite similar to the equipment of Jedi Knights, as can be seen from the video presentations available on the Internet.

Cosmic toilet, cosmic price

“Space, endless expanses. The year is 2020. These are the adventures of the ISS space station:… "

NASA has announced tests for a new toilet to be installed on the International Space Station (ISS). The entire $ 23 million set was intended primarily for women. If the tests are successful, this high-tech toilet will be used during the Artemis II mission in three years.



Most of the room toilets developed to date work with negative pressure, which draws the "effects of human metabolism" away from the body and transfers it to appropriate storage systems. Now the Universal Waste Management System (UWMS) has been designed, which can be translated using the Universal Waste Management System. It works on a similar principle but has a number of new features that help maintain hygiene and reduce odors, which is quite important in the tight spaces of spacecraft.

New space toilet:


NASA reports that the UWMS is 65 percent smaller and 40 percent lighter than the toilet that has been on the ISS since the 1990s. One of the most important improvements is the automatic start of suction as soon as the toilet lid is lifted. This is to help reduce the spread of unpleasant odors.

Since the toilet is designed for people who are weightless, it will also have foot mounts and special guides to "anchor" the astronauts. In the old design, special thigh straps were used for this purpose.
Although the information from NASA does not make it clear that the new space toilet will be comfortable, the agency's experts believe it will be a more efficient project than the solutions in use today. According to NASA, the new toilet cleans and maintains itself faster, especially thanks to the new solutions for urine drainage. The toilet is also intended to be completely isolated from other parts of the spaceship to ensure user privacy.

Robots run on alcohol

Traditionally, the "muscles" of small robots worked with external power sources or batteries. In the latter case, this increased the weight and size of the robot considerably. The best batteries have an energy density of around 1,8 megajoules per kilogram. This is a fraction of what is made from animal fat, around 38 MJ / kg. The methanol-powered muscles used by RoBeetle can reach an energy level of up to 20 MJ / kg through catalytic combustion.

Engineers created an interactive paper

Perhaps in the near future we will be able to operate our devices, such as laptops or tablets, with an ordinary sheet of paper. The engineers of Purdue University developed a technology that enables us to make an interactive keyboard out of paper. The engineers at Purdue University have developed a process that enables paper or cardboard to be coated with "highly fluorinated molecules". This makes the paper dust, oil and water resistant, which means you can print multiple layers of circuit boards on it without the ink smudging.
