One hour of sunlight has enough power to supply Earth with energy for a whole year. Why is sunlight so powerful? Because it is a reaction from the name of a nuclear connection.
This process, which has the potential to generate eternal energy, is considered to be the sacred gravel of the energy industry and many of the world's brilliant thoughts are aiming to develop it.
In an interview with the BBC by the end of 2016, the famous British physicist, Stephen Hawking, who died last March, is the biggest technology that promises the production of a nuclear edge as the largest man promising.
"I would like to see the development of joining energy", he replied, we consulted on the idea that could transform our society most.
"The nuclear effort would be a practical energy source that would give us an undesirable amount, without contamination or global warming," he said.
Unlike traditional nuclear power, produced by separation of atoms – a process known as fighting – this new energy source is created by falsifying-that is, by merging the atoms.
Combines more robust hydrogen to produce helium, a reaction that releases massive amounts of energy, just like what is happening in the Sun.
The idea is, in essence, to create "microsoles" on Earth.
The race to reach the holy rock
Today there is more than 25 private enterprises dedicated to this end, many of them have been funded by some of the most well-known entrepreneurs on the planet, such as Bill Gates (Microsoft), Jeff Bezos (Amazon) and Peter Thiel (PayPal ).
The first private project was Tri-Alpha Energy (or TAE Technologies), located in California, United States, which has existed for decades.
One of the most famous investors was the co-founder of Microsoft, Paul Allen, who died last October.
Commonwealth Fusion Systems is the heavyweight in the sector, established by six professors of the prestigious Massachusetts Institute of Technology (MIT).
Although only one year ago it was considered, it is considered one of the most ambitious projects because it aims to create a reactor prototype for 2025.
Gates and Bezos are both of those who fund this enterprise, along with other famous entrepreneurs such as Richard Branson and Michael Bloomberg.
Also some oil companies are starting to bet on a future without fossil fuels. According to the Bloomberg agency, Italy's Eni SpA led a group that invested US $ 50 million in the Commonwealth Fusion Systems last March.
But some experts believe that the project is not the most likely to move forward in the private sector.
It's a call-in International Thermonuclear Experimental Reactor (ITER, for her acronym in English), built in Cadarache, in France, with a budget of US $ 23,000 million.
There are 35 countries working together in this scientific experiment, which began more than three decades ago.
Those responsible for ITER estimate that they already have a large-scale reactor by 2050.
Many countries also develop their own initiatives. In April, the BBC was able to access the facilities in the Anhui Province, in China, where scientists from that country they claim that they are more advanced than their peers in the USA, the European Union (EU), Japan, South Korea and Brazil.
But all of these problems are facing the same problem, which is so curious about how to perform a nuclear attempt.
The big challenge is how to generate more energy than what is spent in the process.
The fusion is based on a heating issue to a very high temperature, which is more than hundreds of millions of degrees. In that condition, the issue is called plasma.
Unlike the Sun, the Earth does not have the conditions to keep that plasma warm. To achieve this, the plasma must be just from other materials. For this, there are some special cameras in the form of a called circleatokamak.
And tokamak they use powerful magnets to create a magnetic field that stores the isolated plasma. The problem is that today these cameras use more energy than they succeed in producing.
The solution indicated by companies like Commonwealth Fusion Systems is to use better magnets, but the truth is that no-one has managed to overcome this great barrier.
Some like the Tesla creature, Elon Musk, believe that they would have to invest to create solar panels and better batteries to hold the energy of the Sun, instead of wasting money trying to reproduce our star.
However, an IP Group Plc investor said to the Bloomerg agency, although energy and the merger take more than it is desirable, many of the innovations created for this industry they prove very profitable.
"Research companies patent a lot of their creatures, from software that simulates plasma combustion to 150 million degrees of undergraduate to a new type of magnet with medical applications," said Bloomberg.
In the meantime, we will have to wait to know if Professor Hawking's desire for unlimited and clean energy can be realized.
