Is #space based #solar power feasible? And viable? Honoured to be invited to give a talk to the Tweeddale Astronomical Society on

Solar Power from Space

#Silicon is relatively heavy and inflexible. In contrast, organic #SolarCells ☀️ can be #flexible and are much lighter. Organic solar cells made with small molecules showed no damage after three years worth of #radiation ☢️ https://news.umich.edu/light-flexible-and-radiation-resistant-organic-solar-cells-for-space/

Growing efficiencies of near-infrared #lasers make them preferable over #microwaves, allowing the transmission antenna on the spacecraft to be scaled down from hundreds of meters across to about half a meter 📏. #OverviewEnergy successfully tested a system that transmitted “multiple thousands of watts” of power using a near-infrared laser from an aircraft flying at an altitude of 5,000 meters to a receiver on the ground https://spacenews.com/overview-energy-demonstrates-technologies-for-space-solar-power/

SpaceShipTember 2025 - Day 25 - Lasers
One of many phased-array laser emitters on the lunar surface which formed the beginning of the beamed-power network.

The primary obstacle has always been #LaunchCost, but the advent of #reusable ♻️ rockets is rapidly changing the economics of space access, making the financial case for #SBSP increasingly attractive https://www.weforum.org/stories/2025/10/space-based-solar-power-energy-transition/

📊 2025 : The simulations show that if the swarm design can deliver #electricity at six to nine times the projected 2050 cost of ground PV, system #costs fall by 7%–15% 📉. At that price, #space -based #solar ☀️ can displace up to 80% of wind-plus-solar capacity and cut #battery needs by more than 70% https://www.sciencedirect.com/science/article/pii/S2542435125002557

Based on the cost 💶 assumption of #SBSP, the projected value-adjusted levelised cost could even reach 69 EUR/MWh for the first system. Applying a learning curve metric already shows cost reduction potential in the setup of the first 10 SPS station deployments, leading to an estimated VALCoE of 49 EUR/MWh. This means that SBSP has the potential to even become a cost-competitive renewable technology https://www.rolandberger.com/en/Insights/Publications/Space-based-solar-power.html

The #ZEUS #SBSP #satellite constellation is designed to harness #solar ☀️ power and transmit it wirelessly to the lunar base. It will enable the continuous operation of #ISRU facilities at the lunar🌙 South Pole https://www.sciencedirect.com/science/article/pii/S009457652500270X

The #UK 🇬🇧, #US 🇺🇸, #Japan 🇯🇵 and #China 🇨🇳 are now investing in #space based solar ☀️ power. The #atmosphere reflects around 30% of the #energy that reaches our planet while it absorbs around a quarter before it even reaches the Earth's surface. Space-based 🌌 solar panels can avoid this effect, but can remain in near-constant sunlight https://www.bbc.com/future/article/20251029-the-beam-dream-should-we-build-solar-farms-in-space
