Amazing inventions of recent years that you did not know about

 

Progress does not stand still, and in recent years mankind has invented many things that are not yet known everywhere. The creation of most of them brings us very close to the world of the future, which is shown in science fiction films. Let's figure out which of these inventions will very soon have an impact on our lives.

Solar thermal fuel

One of the main reasons why humanity has not yet fully switched to the use of solar energy is the high cost and low efficiency of its long-term storage. Nevertheless, it would be foolish to refuse from this environmentally friendly and capacious source of meeting all the needs of earthlings, so Swedish scientists took up the solution to this problem.

They soon succeeded in inventing a special liquid called solar thermal fuel. This substance is able to hold and store solar energy inside itself unchanged. The innovative fuel contains nitrogen, hydrogen and carbon. When the light rays strike the molecules of the elements, they capture solar energy and form an isomer - a storage facility with a 20-year shelf life.

Wood that does not burn in fire

Despite the environmental friendliness and positive properties of such a building material as wood, its use is associated with many negative aspects. Massive deforestation, for example, is damaging the environment. In addition, buildings made of wood are characterized by a high fire hazard.

To solve the above problems, Chinese scientists have created a synthetic tree. The resulting material very successfully imitates wood, but at the same time it does not burn, does not collapse under the influence of water, acids and other aggressive factors.

Multifunctional airgel

All means are good in the fight for a clean environment. Thinking about how to recycle the ubiquitous plastic that has flooded both water and land, scientists have invented a multifunctional airgel. The inventors note that to create this amazing material, they worked with plastic, which has already been recycled many times, which means it was doomed to be stored in a landfill.

From one bottle thrown into the trash, you can get a layer of airgel the size of an A4 sheet. This flexible, porous and very lightweight material is extremely durable. It can be used as a heat or waterproofing agent, as well as a technical sorbent for air and water. It is possible that soon, with the help of the once toxic plastic waste, we will be able to cleanse the planet of the substances that have polluted it.

Thought-guided wheelchair

Not so long ago, a graduate of the Novosibirsk State Technological University presented his invention to the world - a wheelchair controlled by the power of thought. The device is designed specifically for completely paralyzed people who can only breathe and think on their own.

Not only does the device quite deftly move with a load on sidewalks and asphalt, it can also independently lower the owner down stairs or climb hills. This feature is available thanks to the track-type sidecar design.

Metal 3D printers

3D printers have appeared for a long time, but for a very long time it were not possible to use anything other than plastic as ink for them. Finally, humanity made a breakthrough and invented printers that work with metal.

It is assumed that in the future, these devices will be mainly used for printing metal elements of various mechanisms. Soon, manufacturers will not need to maintain warehouses littered with parts, and buyers will bypass several shops to buy the desired product, because any of them can now be printed in real time.
