A photovoltaic Dyson sphere is a theoretical megastructure that could provide vast amounts of energy for interstellar space travel and large-scale technological endeavors.

New research from Germany has investigated for the first time the idea of building a photovoltaic Dyson sphere, a theoretical ...

It's still quite an engineering feat though, requiring 1.3×10 23 kg of silicon. More information: Ian Marius Peters, The photovoltaic Dyson sphere, Solar Energy Materials and Solar Cells (2025).

But why would anyone ever spend so much money to make an (almost) perfectly round sphere of silicon? Simple, to more precisely define what a kilogram is. People throughout the world (yes ...

As civilisations become more and more advanced, their power needs also increase. It’s likely that an advanced civilisation ...
