Fusion power has been 15-20 years away from invention since like the 1960s lol
🇩🇪 GERMANY IS TRYING TO BUILD A STAR ON EARTH — AND IT COULD CHANGE ENERGY FOREVER
Deep inside experimental fusion machines, scientists are trying to recreate conditions similar to those inside a star. Instead of burning coal, gas, or oil, nuclear fusion works by forcing light atomic nuclei together, releasing huge amounts of energy in the process. The problem is that controlling this reaction on Earth is incredibly difficult.
Germany is betting heavily on one unusual design: the stellarator.
One of the companies leading the effort is Munich-based Proxima Fusion, a spin-off from the Max Planck Institute for Plasma Physics. Its machines use incredibly powerful and precisely shaped magnetic fields to hold superheated plasma in place—plasma that can reach temperatures of millions of degrees.
Proxima plans to build an experimental machine called Alpha near Munich in the early 2030s. Its goal is to demonstrate that a stellarator can produce more fusion energy than the energy used to heat and sustain the plasma. But Alpha would still be an experimental machine, not a commercial power plant.
Proxima is planning a machine called Stellaris at the former Gundremmingen nuclear site in Bavaria. The company says it could become the first commercial stellarator designed to send fusion-generated electricity to the grid—potentially during the 2030s.
Germany is not relying on one company alone. Its national fusion plans aim for a demonstration plant toward the end of the 2030s, followed by a first-of-a-kind fusion power plant in the 2040s. More than €2 billion in new public funding is being directed toward fusion research and infrastructure through 2029.
Can humans actually turn a miniature star into a reliable power station?
Creating fusion is one challenge. Controlling it continuously, extracting useful energy, protecting the machine from extreme conditions, and producing electricity economically are completely different problems.
If Germany and other fusion programs can solve those problems, the payoff could be enormous: a new source of reliable, low-carbon electricity based on the same basic reaction that has kept the Sun shining for billions of years.
The race is no longer just about proving that fusion is possible.
The real race is to make it useful.
And somewhere in Germany, scientists are now trying to take the first serious steps toward doing exactly that.
