In 2019 Greta Thunberg traveled through the world in different transport avoiding catching a plane. This young man of 16 years I wanted to emphasize the impact that they have on the global contamination of the aircraft and how difficult it is to travel without using one of them.
Months later, the quarantine by the coronavirus has cleaned the skies of countries before the decrease of the traffic of car and aircraft. It is evident that these two industries are a major contributor to the emission of greenhouse gases. However, when the world containing the virus, it’s not going to stop travelling, and the airplanes returned to the skies, what would be the solution? These are more sustainable, less polluting.
It is a great challenge, yet you have not presented an alternative that can replace the airplanes of combustion, while the electric or hybrid cars yes fucking more force on the roads. This does not mean that long-term this situation will change, some projects promise long-term solutions that could help to make greener aircraft.
An article in the journal AIP Advances presents a prototype engine for aircraft you do not need to use any fossil fuel to get the power required. Wuhan University, is responsible for this project and the results of the tests open up the hope in a future aviation industry total electric and less polluting.
As explained in the article, this new engine works by compressing the air and ionizándolo with a microwave. This process generates a plasma that produces the necessary impulse. With this technology, some day it would be possible to flying an airplane in the atmosphere that only use electricity and air.
This is a simple prototype, is very far from being able to replace the giant engines of a commercial aircraft, but its results are very positive. Has been able to throw a steel ball of 1 kg to a height of 24 mm in the air. Comparing these data with the size with which they built the prototype, this strength is equivalent to that generated by turbojet engine-standard.
The aviation world, with their combustion engines expel to the atmosphere of our planet the 2% of global carbon emissions in the worldaccording to datas of the International Air Transport Association (IATA). Delete in this industry the use of fossil fuels with engines as this would be a great relief to the climate of the Earth.
