Jan Jäderberg (that has been technical chief at Hyab) is today in front of creating Fusion-energy with strong "magnet-walls with new patents with mirror-technique". Working fusion-power can replace thousands of Nuclear reactors and coal-plants.
Fusion involves joining atoms together to release large amounts of energy, to be compared to nuclear power which bases its technology on splitting atoms. The idea of fusion energy is inspired by the sun, which is like one big fusion power plant. The Sun's strong gravitational forces create a natural environment for a so-called plasma, which can enclose and merge gas particles at high temperature.
Scientists have been working since the 1950s to recreate fusion energy on Earth. There are now conditions for creating plasma and heating it to a sufficiently high temperature, over 100 million degrees. But the challenge of stabilizing the plasma still remains. It is needed to create a net surplus of energy, i.e. that the fusion process produces more energy than is supplied. A prominent way to confine the plasma is via magnetic confinement fusion. But currently there are not strong enough magnetic walls that can generate fusion energy.
An example is the international fusion reactor Iter, which is under construction in France. Here, the world's researchers work with a tokamak reactor, whose metallic ring-shaped capsules enclose the plasma with surrounding magnets. The reactor should be completed in 2025 and generate the world's first working fusion energy. But it may still be until 2050 before Iter can deliver large-scale fusion power.
This is where the Novatron comes in. By thinking outside the box, that engineer and KTH alumnus Jan Jäderberg has developed a revolutionary technology that can accelerate the entire development.
- We have developed a solution that can make the plasma concave. Then you can build strong magnetic walls that can withstand the heat needed to achieve fusion, he says.
The concave shape is achieved by "pressing" the plasma with the help of a mirror machine, he says.
- It allows charged particles to bounce between different mirrors and create a stronger magnetic field. The advantage of Novatron's technology is that it is simple and cheap compared to Iter's tokamak reactor, which is complex and expensive. We expect that Novatron's technology will cost one tenth of the ITER project, he says.
