These can be transfer into tokamaks to create fusion power at energy levels the world has never seen contained before in order for fusion energy to be produced at a level where more energy is created then used to create it. These small magnets in the video are already up to 20 Tesla's of energy and thousands of amps of power. They plan on scaling this up to thousands of kilometers of length in giant coils used to help the Tokamak to operate had very high energy levels at extreme temps to 20 kelven. "The last 12 months have seen very rapid developments in magnet technology at Tokamak Energy. Senior HTS Magnet Engineer Greg Brittles describes the team's achievements in developing a very neat, modular coil design that makes for extremely robust, easy to assemble, and ultra-stable high temperature superconducting (HTS) magnets. Greg shows a REBCO magnet that has produced a field strength well in excess of 20-Tesla, which we believe to be a world first. This crucial milestone for Tokamak Energy proves the possibility of high temperature superconductors to deliver the fierce magnetic fields required for fusion energy and the team are now addressing the challenges of scaling up these magnets significantly for use in future tokamaks." Just for reference for people wondering what 1 Tesla equates to " A refrigerator magnet is 100 gauss, a strong refrigerator magnet. The typical strength of the Earth's magnetic field at its surface is around a half a gauss. So those are everyday units of magnetic fields. There are 10,000 gauss in one tesla.Sep 23, 2014"
