One hour of sunlight is enough to power the Earth for a whole year. Why is sunlight so powerful? Because it results from a reaction called nuclear fusion.
This process, which has the potential to generate eternal energy, is considered the holy grail of the energy industry and many of the brightest minds in the world are determined to try to develop it.
] In an interview with the BBC in late 2016, the famous British physicist Stephen Hawking, who died last March, said the technology to generate nuclear fusion was the most promising for humanity .
" I would like to see the development of fusion energy ," he replied, consulted on the idea that could most transform our society.
"Nuclear fusion would be a source of practical energy that would give us an inexhaustible amount of energy, without polluting or generating global warming," he said.
Unlike traditional nuclear energy, which is generated by the separation of atoms – a process known as fission – this new source of energy is created by fusion, c & 39; that is, the union of atoms.
Specifically by the fusion of hydrogen producing helium, a reaction that releases enormous amounts of energy, as happens in the Sun.
The idea is essentially to create "microsoles" on Earth.
The race to reach the Holy Grail
Today, there are more than 25 private companies dedicated to this objective, many of them being financed by entrepreneurs among the most famous on the planet, such as Bill Gates (Microsoft), Jeff Bezos (Amazon) and Peter Thiel (PayPal).
Tri-Alpha Energy (or TAE Technologies), based in California (United States), has been in existence for two decades.
One of his most famous investors is Microsoft co-founder Paul Allen, who pbaded away last October.
One of the heavyweights of the industry is Commonwealth Fusion Systems, a start-up founded by six professors at the prestigious Mbadachusetts Institute of Technology (MIT).
Although it was created only a year ago, it is considered one of the most ambitious projects because it aims to create a prototype reactor. here 2025.
Gates and Bezos are two of They finance this venture, alongside other famous entrepreneurs such as Richard Branson and Michael Bloomberg.
Moreover, some oil companies begin to bet on a future without fossil fuels . According to the Bloomberg agency, the Italian Eni SpA led a group that had invested 50 million US dollars in Commonwealth Fusion Systems in March
. An international effort
But some experts believe that the project that has the best chance of progressing is not the private sector.
This is the so-called International Thermonuclear Experimental Reactor (ITER ), under construction in Cadarache, southern France, with a budget of $ 23,000 million.
35 countries are collaborating in this scientific experiment, which began more than three decades ago.
ITER officials estimate that a large reactor will be ready by 2050.
Several countries are also developing their own initiatives. Last April, the BBC was able to access the facilities of Anhui Province in China, where scientists from that country claim to be more advanced than their peers in the United States, in the United States. European Union (EU), Japan, South Korea and Brazil
The problem
But all these projects face the same problem, which is not interesting to know how to achieve nuclear fusion.
The big challenge is generating more. energy spent during the process.
The fusion is based on the heating of materials at very high temperatures, exceeding hundreds of millions of degrees. In this state, the material is called plasma.
Unlike the Sun, the Earth does not have the necessary conditions to keep this plasma warm. To do this, the plasma must be isolated from other materials. To do this, some special cameras shaped ring are used to s tokamak .
The Tokamak uses powerful magnets to create a magnetic field that keeps the plasma isolated. The problem is that today, these cameras consume more energy than they manage to produce
Companies such as Commonwealth Fusion Systems suggest to use better ones. magnets, but the truth is that nobody has managed to overcome this big obstacle.
Some, like the creator of Tesla, Elon Musk, believe that it would be necessary to invest in the creation of better solar panels and batteries to capture the energy of the sun instead of wasting money trying to replicate our star
However, investor IP Plc Group told Bloomerg that even though the energy of fusion After having exceeded the desired development time, many innovations created for this industry prove to be very lucrative .
"Research companies are patenting many of its creations, ranging from software simulating the burning of plasma to 150 million degrees centigrade to a new type of magnet with medical applications," Bloomberg reported. .
In the meantime, we will have to wait to see if Hawking teacher's desire for unlimited, clean energy can become reality.
