Is space-based solar power a pipe dream, or an actual possibility?

With ideas ranging from supercharging satellites to city-size space collectors, I delved into the topic for the BBC in my latest story out today.

Enjoy!

Space power: The dream of beaming solar energy from orbit
Harvesting solar energy in orbit and beaming it down to Earth is a decades-old idea. Now, a raft of companies say they could make it a reality.

What if we could power the entire planet with continuous clean energy from space? 🌍☀️🛰️

This isn’t science fiction—it’s a concept called Space-Based Solar Power (SBSP). Let’s break it down. 🧵👇

Space-based solar power could significantly advance net zero efforts in Europe
Solar panels situated in space could reduce Europe’s requirement for land-based renewable energy by up to 80%, expediting the journey to net zero, according to new research from King’s College London. The study, published in Joule, analysed the potential of a design by NASA for space-based solar generation, which is planned to be in use by 2050. The findings appear to show the design could also save money by reducing the cost of the whole power system in Europe by up to 15%, including energy generation, storage and network infrastructure costs – an estimated saving of 35.9 billion euros per year.

Hello #MangaArtists I'm developing a thing called #SpaceBasedSolerPower and when working it can contribute to a sustainable & equitable energy transition. I believe it is save the world type of stuff. Launching spacecraft in 3 yrs and would love some cool mission patches. Anyone interested

Mind-blowing news UK startup Space Solar just showed robots can build gigawatt-scale solar farms in space. Leveraging UKAEA robotics, this trial opens up beaming clean energy from orbit 24/7. A game-changer for in-space infrastructure.

The UK based start-up Space Solar has developed a power-beaming technology that can deliver wireless power from space.

Their technology moves us towards a future with clean, continuous, and globally accessible energy. And it’s safe.

Stay tuned.

@pdjeliclark.bsky.social I've spent time reading your book A Master of Djinn on holiday and absolutely bloody loved it. The characters were all brilliant even Abbie. Fatma must have some more stories to tell. It oozes style it would make a movie that could surpass the fifth element for cool.
