Absolute nonsense plans for space generated solar power. IIRC, one of the studies was supposed to be delivered two years ago.

Such huge structures in space will be highly vulnerable to space debris or malicious attacks, to name just two apparently unsolvable security problems. It'll be interesting to see what the numbers say, when comparing the total cost for such a monstrosity with similar plans for solar power generation on the surface of the Earth.

The size of the proposed structure in comparison to big structures on Earth:

The ISS on the left is the biggest structure built in space so far, so, yeah 🤣

Recent breakthroughs include self-healing ☀️ that can maintain their efficiency for tens to hundreds of years. A new efficiency record broke the theoretical limit of 33.7 per cent 📈. The first production of ultra-efficient perovskite solar panels could begin in China 🇨🇳. 🇬🇧 startup is already in the process of commercialising the technology, with hopes of beginning full-scale production at a German 🇩🇪 facility later this year https://www.independent.co.uk/tech/solar-panel-world-record-perovskite-energy-b2445026.html

Are Adityanath and Mukhtar Ansari on the same side now?

The gangster-turned-politician’s son, Abbas Ansari, is a legislator from the Suheldev Bharatiya Samaj Party with which the BJP has renewed its alliance.

📆 March 2023 Due to high and payload weight limits, a strong increase in the specific power of for use is highly desirable. Moreover, truly 🧻 solar cells will enable completely different deployment strategies. Novel solar cell technologies based on organic solar cells or perovskite solar cells offer these advantages of being lightweight, potentially cheap 💶 and fully flexible https://academic.oup.com/nsr/article/10/5/nwad071/7077559

@SkipHuffman would have to be done by with (and probably parts). If were already developed, material would also be available. AFAIK the reactor needs a minimum size, so an experiment aboard a wouldn't be an option. Outside the bots would have the advantage they don't need a , oxygen or sleep
