Limitless clean energy by enabling a sun on earth


Fusion is the energy source of the sun, and if harnessed on earth would provide limitless clean energy on demand. However, the reaction requires a temperature hotter than the core of the sun, a scorching 150 million degrees. Magnets can temporarily contain this heat but it will eventually escape and reach the wall, causing a heat flux comparable to the surface of the sun. Most materials would instantly melt, but StarWarden combines an array of thermal superconductors called heat pipes with 3D-printing to enable more effective cooling than any other technology. Cooling channels then transfer the heat away to be used for energy generation. All of this integrated in a simple, compact and reliable box called the 3D-printed Heat Pipe Array. This allows us to become the warden of this man-made star.
