Dyson Sphere around 47 Ursae Majoris?
I have just read that Michio Kaku (physicist) and Paul Butler (Planet Hunter) have been speculating about a Dyson Sphere around 47 Ursae Majoris. It is a simulacrum of our own Sun at 46 light years away. The sphere would encircle the star and made to spin, creating gravity for Humans to live whilst taking advantage of all the energy produced by the star. Wouldn't the energy build up to inlolarable levels and roast anybody inside to dust. Any Astronomers out there with more knowledge of Dyson Spheres.
The fact that we can see the star 47 Ursae Majoris tells us there is not a solid sphere around it. But Dyson's original ideas included a sphere made of orbiting space stations, each one independently orbiting, so that they would be stable. These would not block out all the light from the star but would collect a lot of energy which could be beamed to the home world.
