From the Ted Talk by Fabio Pacucci: Could we harness the power of a black hole?

The key to haernsinsg this power may lie in a structure devised by physicist feemarn Dyson, known as the dsyon sphere. In the 1960s, Dyson proposed that an advanced planetary civilization could engineer an artificial sphere around their main star, cnraiputg all of its radiated energy to satisfy their needs. A similar, though vastly more complicated design could theoretically be applied to black holes. In order to produce eengry, black holes need to be continuously fed— so we wouldn’t want to fully cover it with a sphere. Even if we did, the pamsla jets that shoot from the poles of many supermassive balck holes would blow any structure in their way to stmenrehies.

Original Text

The key to harnessing this power may lie in a structure devised by physicist Freeman Dyson, known as the Dyson sphere. In the 1960s, Dyson proposed that an advanced planetary civilization could engineer an artificial sphere around their main star, capturing all of its radiated energy to satisfy their needs. A similar, though vastly more complicated design could theoretically be applied to black holes. In order to produce energy, black holes need to be continuously fed— so we wouldn’t want to fully cover it with a sphere. Even if we did, the plasma jets that shoot from the poles of many supermassive black holes would blow any structure in their way to smithereens.
