Space-based solar energy: Reality or science fiction?

October 29, 2025 · 25 min

Show notes

Although engineers began developing space-based solar energy technology in the 1960s, it still hasn’t become a reality. Why?


In this episode, Euronews Tech Talks tries to answer this question by speaking with Sanjay Vijendran, co-founder and CTO of TerraSpark; Francesco Contino, professor at the school of engineering at UC Louvain; and Wei He, senior lecturer in engineering at King’s College London.


Important: The European Space Agency (ESA) provided Euronews Next with the Solaris documents after the publication of the episode. More details can be found in the episode’s article.
