The Dyson Heater is a Dyson Sphere that heats a star to over millions of degrees Celsius. It does this by reflecting photons back to the star they came from. Special heating arrays are installed in the Dyson Swarm that heat the photons before they reach the star. This tool is primarily used for terraforming... if it worked. I just wanted to show you what the Dyson spere would do in real life. It looks the best, and is meant for red giants, plus it makes sence.
