Launching a satellite into space through a huge centrifuge on the ground. SpinLaunch launch video released

At the moment, in matters of space, humanity completely relies on rocket engines, which have a huge mass of shortcomings. But for many years, scientists and entire companies in different parts of the world have been working on alternative technologies for launching objects into space. And one of the concepts was successfully tested the other day.

SpinLaunch decided to go with a technology that involves accelerating an object to be launched into orbit using a huge centrifuge placed on the ground. And last year, the company completed work on a prototype of such a centrifuge in New Mexico, which is capable of launching an object at speeds up to 1600 km / h.

Since October, SpinLaunch has completed eight test flights, but we are interested in the last one, since in this case a camera was attached to the launch object. Watch the video below, be careful, as the picture rotates very quickly.

The flight of the object lasted 82 seconds. An altitude of 7.6 km was reached. Of course, this is incredibly far from the edge of outer space, but in this case we are talking about a prototype for testing the technology as a whole. In addition, the company notes that even the current prototype was used at only a fraction of its maximum power during this launch.

The tests allowed the company to understand that the overall concept is viable. For example, electronics withstand huge specific overloads in a centrifuge.

A full-fledged SpinLaunch L100 accelerator will be three times larger than the current A-33. It will be capable of ejecting objects weighing up to 200 kg at speeds up to 8000 km/h to near-orbital heights. True, even this will not be enough to put into orbit, so we are talking about launching small rockets, which, upon reaching a certain height, will turn on the engines. But such rockets will need a small amount of fuel to put their payload into orbit.

NASA has already signed a contract with SpinLaunch, that is, management considers the technology promising. It is known that the construction of the first full-fledged accelerator will take another couple of years, and the company plans to begin commercial launches in 2025.

The barebone kit is priced at $415, but you can also buy a PC preloaded with 8GB to 64GB of RAM and a 512GB to 2TB SSD. The top version will cost about $1,150.

The novelty stands out, of course, primarily for its design. Moreover, this very design is still associated with one of the functions of the PC. The ring at the top serves as a mode switch. It appears to toggle Windows power modes: Silent, Balance, and Performance Mode.

There are no cardinal changes – these are all the same ultra-affordable devices with the appropriate parameters. Since technically the novelties are almost identical, we will talk about them as a single product.

So, the tablet still has a seven-inch screen with a resolution of only 1024 x 600 pixels. This is a very low resolution for 2022, but the price of the tablet is only $60 ($110 for the Kids version).

It is based on an unnamed 2 GHz quad-core processor, which is 30% faster than the solution in the previous generation of the tablet. RAM has doubled, but it’s only 2 GB. Flash memory is available 16 or 32 GB, since there is a slot for microSD. Also autonomy increased by 40%, and now Amazon promises up to 10 hours of work. From the rest, we can note the appeared USB-C port, a 2 megapixel camera and three colors.

Apple AirPods Pro ruptured a 12-year-old boy’s eardrums, leaving him disabled. The company was sued

Apple AirPods Pro ruptured a 12 year old boys eardrums leaving him

Apple is facing legal action over AirPods.

According to sources, the company was sued due to the fact that a 12-year-old child was injured due to the use of Apple headphones. One would think that the headphones exploded, as this sometimes happens, but in this case the reason is completely different.

Apple AirPods Pro ruptured a 12-year-old boy's eardrums, leaving him disabled.  The company was sued

The child was watching a movie on Netflix using an iPhone and AirPods Pro. At some point, the Amber Alert system (child abduction alert system) went off. Initially, the headphones worked at a low volume, but the sound of Amber Alert was so loud that it ruptured the child’s eardrums and damaged the cochlea. After the incident, the boy suffered from hearing loss, nausea, dizziness and tinnitus. He is now required to wear a hearing aid.

In fact, this happened back in 2020, but, as is often the case, the general public will learn about such incidents much later.

The lawsuit alleges that Apple is aware of “defective” AirPods that do not mute Amber Alerts. What’s more, Apple also didn’t include a warning about a potential issue that users might encounter.

The lawsuit against Apple seeks damages for the boy and his parents, who are under enormous emotional stress due to the situation. The lawsuit seeks “punitive damages in an amount that will punish defendants for their conduct and deter other technology companies from engaging in such misconduct in the future.”
