Overview Energy wants to launch #satellites 🛰️ into space that are equipped with #solar panels that convert sunlight into electricity. With this electricity, the company wants to generate laser light in the near-infrared spectrum. The satellites are to be positioned in a geostationary orbit, about 36,000 kilometers above the Earth.
#SolarPanels in space 🌌 could provide 80% of #Europe’s renewable energy by 📆 2050 https://www.theguardian.com/environment/2025/aug/21/solar-panels-in-space-could-provide-80-of-europes-renewable-energy-by-2050
• Current international state of the art of #SBSP
• #ESA activities related to SBSP

2022, #ESA awarded two parallel cost-benefit analysis studies, which will evaluate the ‘business case’ for space-based solar power in #Europe 🇪🇺 https://www.esa.int/Enabling_Support/Preparing_for_the_Future/Discovery_and_Preparation/ESA_reignites_space-based_solar_power_research
With a fraction of the investment directed at other technologies, 90% of the barriers to #SBSP could be de-risked within five years, preparing it to scale 📈. The intensity of sunlight in space 🌌 is significantly higher, meaning space-based panels generate far more #energy 🔋 per square metre than their terrestrial counterparts, freeing up valuable land.
This superior energy density also translates into a dramatic reduction in material usage https://www.weforum.org/stories/2025/10/space-based-solar-power-energy-transition/
Space-based #solar ☀️ power : #ScienceFiction author Isaac #Asimov popularised the idea in 📆 1941. Advances in #robotics, wireless power transmission and sharply falling #LaunchCost are narrowing the gap between concept and reality https://www.scmp.com/opinion/china-opinion/article/3347692/why-chinas-space-based-solar-power-next-frontier-green-energy
⬆️ @sundogplanets >> The costs are high, the environmental effects are potentially catastrophic, there are huge safety issues, and the benefits are negligible.
@nebulousmenace >> *nods* my hope is they're just in it to harvest venture capital.
That was #ReflectOrbital in October 2025. Now, yet another startup #Helio makes the case for #SpaceSolar or #SBSP
This one seeks to harvest #solar energy, convert it to microwaves, and transmit it wirelessly to Earth
