The best inventions of 2020

The year 2020 was a year full of smart innovations, as we heard about a machine that generates water from the air, a vertical mobile TV with wheels from Samsung, and a smart toothbrush that does not even need you to hold it, and although we are still at the beginning of 2021, but the smart inventions and innovations of 2021 that are drawing Humanity with it for an easier and more developed life.

Artificial intelligence for mixing cosmetics:

When it involves beauty, there's nobody size fits all. That's why cosmetics company Perso, a clever dispenser that mixes lipsticks, foundations and skincare products tailored to each individual user. The user logs into the Perso online app and uploads a selfie, which the app's algorithm will evaluate and address common skin concerns like dark spots, wrinkles and blemishes. For skin care formulations, the application will also take into account environmental conditions such as humidity and sun exposure before mixing the desired product by the user herself. With the smart dispenser, there are interchangeable cartridges for blending products, meaning users can easily switch between blending for skincare or makeup.

Lithium metal batteries:

Electric cars find it very difficult to sell for several reasons. They are relatively expensive, and you'll only drive them for many kilometers before they have to be recharged, which successively takes for much longer than you'd spend at the gas station. In short, all of these drawbacks can be summed up in the limited capabilities of lithium-ion batteries.

However, a Silicon Valley startup says it now has a battery that will make a large audience of consumers more receptive to electric vehicles: lithium-metal batteries, developed by QuantumScape.

According to the results of preliminary tests, the battery can boost the range of electric vehicles by 80%, and can be charged quickly.

If QuantumScape succeeds in its work on lithium-metal batteries, perhaps electric cars will finally become attractive to millions of consumers.

green hydrogen:

Hydrogen has long been seen by many as a potential alternative to fossil fuels; It burns cleanly, emits no carbon dioxide, and is energy intensive. Therefore, hydrogen may be a great way to store energy from renewable sources, and it are often made into a liquid industrial fuel as an easy-to-use alternative to gasoline and diesel. But most hydrogen is now made up of gas , during a process that pollutes the environment and drains tons of energy.

But the rapidly falling cost of wind and solar power means that green hydrogen is now both physically and practically obtainable. Some European countries have already begun to build the necessary infrastructure.

High tech teacher:

With the aim of solving computer science and mathematics learning problems, ABii was developed, a robotic tutor that aims to bridge the math and reading proficiency gap for fifth graders. “ABii” is not just a toy, but a robot that is designed to work with teachers, and increasingly with parents now, after many children are receiving their education from home due to the precautionary measures to combat the exacerbation of the Corona pandemic. The ABii robot uses a camera to detect changes in students' attention and refine its teaching approach to suit each individual student. The ABii bot includes regularly updated lesson plans to meet country-specific national standards for school versions and home versions as well.

Generating water from air:

With climate change accelerating, water -H2O- is more valuable than ever, especially in places where water is hard to reach. Years ago, humans began trying to exploit various water sources, refining sea water, and even benefiting from the purification of polluted water. But a water generation invention we can categorize as the smartest of its kind, the portable water generator invented in 2020 produces fresh drinking water from an often overlooked source.

Users throw discarded plant and animal materials, such as wood chips or walnut shells, into a WEDEW-heated generator machine, releasing water vapor into the air during the process, then condensing the steam into potable water.

The entire system, which also includes the battery storage and cooling unit, has only 40 feet of space. These generators were used with the help of the World Food Program in a refugee camp in Uganda as well as some places in Tanzania, Sky Source reported.
