That's "Dyson sphere" after Freeman Dyson, the astronomer and postulator of
the slightly off-the-wall notion that if you broke down all the matter in
all of the planets & planetoids orbiting the sun, you could then
reconstitute it all in a hollow shell around the sun with a radius
equivalent to the earth's mean orbital radius.
The theory goes that you could then harness _all_ the sun's energy, rather
than just the tiny portion that happens to fall on the Earth's surface.

What's always puzzled me is what you would do with the Earth's biosphere
while you were constructing this outsized beach-ball, and whether it
wouldn't be too fragile to survive more than a couple of hundred years,
which would seem a bit of a waste, having gone to all that effort.
