1.  Eternal headphones

Every second inhabitant of the planet uses headphones daily - some people listen to music in the gym, someone watches movies while waiting for a plane at the airport, and someone uses headphones during working online conferences. Today, few people use standard wired headphones - people are increasingly buying wireless ones because they are more convenient. However, these headphones are constantly discharged, so they need to be charged regularly - which is also not very convenient. The solution to this problem was a new invention by JBL - they released wireless headphones that do not need charging. Each earpiece has a built-in mechanism that absorbs the sun's rays. This allows them to build up a charge, so people can safely forgo regular charging.

The user can connect the prototype device to a smartphone via Bluetooth, just like regular headphones. And the built-in battery, if necessary, can be fully charged in two hours via a USB cable. This charge is enough for 24 hours of headphone operation.

The developers claim that an hour and a half of walking in the open air makes it possible to extend the operation of the headphones by 68 hours, and two hours a day - by 168 hours.

2.  WiFi 6 and 5G

New communication and wireless Internet standards, on the one hand, help to work remotely from one point at high speed, on the other hand, they contribute to the development of the Internet of things and artificial intelligence and make the data transfer more secure.

The main benefits that 5G provides are high-speed video streaming with minimal latency - that is, improved mobile broadband. It also helps people who use betting regularly - more information about it you may find at

In addition, according to Accenture, 5G will support up to 1 million devices per square kilometer. And the new communication standard will ensure the smooth operation of autonomous drones or remote intensive care units.

With the help of 5G, many employees will finally move to remote work, and companies will be able to make decisions faster based on streaming data analytics. From 2021 to 2025, technology will bring the US economy up to $2.7 trillion and up to 16 million jobs.

The new Wi-Fi 6 standard will add a new 6 GHz frequency to the two already available - 2.4 and 5 GHz. It has the same goals as 5G: it helps speed up the Internet connection (up to 2 Gb / s for mobile devices), make it more stable and broadband - it will be possible to connect even more devices to one point. In this case, the network itself will distribute Internet traffic between devices, depending on their power.

Among the benefits of Wi-Fi 6 for business are the higher speed and quality of service of existing services; support for new services and applications; the possibility of creating remote and wireless offices.

3.  Lithium metal batteries

One of the latest developments for the automotive market is lithium metal batteries. According to experts, this invention can significantly change the car market. The energy density of such batteries is 1 kWh per liter of volume. This is about twice as much as lithium-ion batteries. Thanks to this, electric cars will be able to charge much faster, and their charge will last 80% longer.

Today, the American startup QuantumScape is developing such batteries. One of the confirmations of the prospects of the project is that Bill Gates himself is among the investors of this project. The startup has been developing lithium-metal batteries since 2020. The first successful tests of this invention allowed the company to enter into cooperation with Volkswagen. This car brand will start producing electric vehicles with these batteries from 2025.

4.  3D printing

At present, it is additive technologies that are becoming a profitable alternative to traditional production. Unlike traditional production, these technologies do not require huge investments and resources. Another significant advantage is the significantly lower level of waste.

3D printing is a new kind of work for many industries. In medicine and healthcare, 3D printers are used to print cables and other parts for medical equipment. Another amazing experiment is the 3D printing of human bone fragments directly in the body, instead of damaged or lost ones. To do this, use special biocompatible ink.

According to Grand View Research, the growth of the global 3D printing market from 2020 to 2027 will be more than 14%. By 2027, there will be 8 million 3D printers in the world. With the help of 3D printing, clothes and shoes, interior items, mechanical parts, and even prostheses are already being created today. 3D printers print many parts for the Rutherford engines installed on the Electron launch vehicle.

5.  Messenger RNA vaccines

Vaccines are something that has become very popular in the last two years. During the pandemic, all the largest companies in the world began to actively develop vaccines and drugs for coronavirus, but the RNA vaccine is one of the most advanced developments in medicine over the past 20 years.

There are currently two vaccines on the market based on this technology: Pfizer and Moderna. Both are anti-coronavirus.

Conventional - vector - vaccines contain a weakened or inactive causative agent of the virus. mRNA-based vaccines induce the body to produce a fragment of the protein contained in the COVID-19 pathogen, which immediately attacks the immune system. As a result, there is a strong immunity to the virus, the body becomes resistant to infection.

Messenger RNAs can be well and quickly modified for any new virus strain - this is precisely their advantage. They can also be used to fight infections, cancer, and other serious illnesses.
