They create the first quantum battery: what advantages do they have?



We have seen a lot of research related to the quantum computing and the quantum communications. With a quantum computer it is possible to process information at unthinkable speeds, ideal for mathematical calculations. In communication, we have forms of transmission that are impossible to break. But what have you never heard of? quantum batteries?

It is normal that you have not heard it, since this is the first time that a group of scientists has demonstrated the application of superabsorption principle of quantum mechanics in a real device. Quantum physics is full of phenomena and concepts that may seem impossible, and superabsorption is one of them.

Super absorption to create quantum batteries

In the superabsorption, molecules can become so entangled with each other that they can begin to act collectively, in this case increasing the ability of a molecule to absorb light. Specifically, this collective effect is that the transitions between the states of the molecules constructively interfere with each other. This type of interference occurs in all types of waves, including light, sound or water, and happens when different waves add up to produce a major effect than the one they would generate separately.

Thus, instead of generating a larger wave in the water, this effect allows the combined light molecules to absorb light more efficiently than if each molecule acted individually. This effect can also be applied to batteries, since the more molecules with stored energy there are, the more efficiently that energy can be absorbed. Thanks to this, the larger the size of the battery, the faster it will charge.

The problem with superabsorption is that it was only a theory, and had not yet been demonstrated on a scale large enough to build quantum batteries. To do this, scientists have layered an active layer of light-absorbing molecules with a dye called Lumogen-F Orange, in a microcavity between two mirrors.

The mirrors were created by using alternating layers of dielectric materials such as silicon dioxide and niobium pentoxide to create what is known as a Distributed Bragg Reflector. The result is mirrors that reflect much more light than a mirror like the one we have at home, which increases the time that the light lasts in the cavity.

Bigger batteries charge faster

They then used ultrafast transient absorption spectroscopy to measure how the dye molecules stored energy and how fast the device discharged. There, they found that as they increased the microcavity size and the number of molecules, charging time decreased.

The effects of this research could be very important, since they could allow ultra-fast charging of electric cars and all kinds of batteries in just a few seconds. The researchers say it’s too early to see what effects these batteries may have, but they are a great first step in bridging the gap between Lab tests with real-world applications.

Soon, the researchers say they can explore how to combine this system with other ways of storing and transferring energy to create real devices that take advantage of this principle.

NASA postpones first manned flight of Boeing’s Starliner



NASA postpones first manned flight of Boeings Starliner

NASA announced the postponement of the first test manned flight of the Boeing CST-100 Starliner. It will take place not in April, but in May, after the Axiom Mission 2. Reportedly, the team is now assessing the readiness of the ship and conducting final pre-flight checks.

NASA postpones first manned flight of Boeing's Starliner

The reason for the delay was the need for additional testing of the Starliner manual control system. It is needed in case of a software failure so that the ship does not lose control.

The first Starliner crew will include astronauts Barry Wilmore and Sunita Williams. If everything goes according to plan, they will have to spend about two weeks on board the ISS. After the successful return of the ship, it will receive NASA certification for regular manned flights, such as SpaceX previously received with its Crew Dragon spacecraft.

Note that the development of Starliner has been going on since 2014, but so far the ship has not received permission for regular flights.

Former head of Google China is preparing his own AI that will surpass ChatGPT



Former head of Google China is preparing his own AI

Looks like the AI ​​race is just getting underway. Former Google China president and Chinese-Taiwan venture capitalist Li Kaifu has revealed that he is launching a new AI project called Project AI 2.0. And this is not just another chatbot similar to ChatGPT. The novelty will be able to offer more than just the generation of pictures and text.

Details about the project have not yet been given, but it is already known that Kaifu has funded the computing power for Project AI 2.0 and intends to attract the best specialists from around the world for his project.

According to the businessman, the technology that is being created for Project AI 2.0 may become the most significant in the world in the near future. At the same time, there is no information about the launch date.

Li Kaifu announced his plans after Chinese technology companies including Baidu, Alibaba and Tencent announced their versions of ChatGPT-like chatbots. However, despite the competition, the former head of Google China is confident that Project AI 2.0 will be able to stand out from the rest due to its focus on global reach and productivity applications.

In China, an orgy of discounts on cars is raging. Discounts reach 5000-6000 dollars, and somewhere they can give a whole car



In China an orgy of discounts on cars is raging

In China, prices for cars fell. According to the Chinese Cars resource, many brands or their dealers offer cars at huge discounts, and in one case, you can get a second car as a gift!

In China, an orgy of discounts on cars is raging.  Discounts reach 5000-6000 dollars, and somewhere they can give a whole car

Almost all major market players offer discounts. The Chery Tiggo 8 Plus, for example, is on sale for around $4,500, bringing the base version to just $14,000. BYD machines are on sale with discounts up to $3,000.

The premium brand Zeekr lures otherwise: the 001 electric car is offered 22-inch wheels and a Z-Sport exterior and interior package, which would cost $5,100 in total. The Changan Deepal sub-brand offers both discounts and gifts at once, for a total of approximately $6,400.

But one of the Toyota dealers did the most impressive. When you buy the bZ4X electric crossover at full price, you get a budget Toyota Vios sedan as a gift, which in itself costs almost $11,000!

The situation with huge discounts began to take shape since the beginning of the year, when Tesla cut the prices of their cars very much. The source adds that most of the discounts do not apply to the newest gasoline models, but, as we can see, there are exceptions.
