Studying How to Bring Solar Power Down to Earth

PARIS (ESA PR) — Solar energy generation keeps on becoming cheaper and more efficient, but some basic limitations will always apply: solar panels can only generate power during the daytime, and much of the sunlight is absorbed by the atmosphere as it shines downward. So ESA is working on the concept of collecting solar power up in orbit, where sunlight is up to 11 times more intense than across European territory, […]

Russian Space Systems Developing Space-based Solar Power Satellite

MOSCOW (Rosatom PR) — The Russian Space Systems holding (part of the Roscosmos State Corporation) has developed a project for a promising solar space power plant (SCES). It is designed to supply power to hard-to-reach – island, mountainous and northern – regions of the Earth, as well as for scheduled and emergency recharging of spacecraft.

How does a space solar station differ from those familiar to everyone on the ground? In the Earth’s atmosphere, the sun’s rays are scattered and partially lose their energy efficiency. In outer space, the efficiency of using solar energy is ten times higher. RCS scientists proposed to convert it into a laser beam and transmit it to Earth with minimal energy loss.

Experts: Reusable Launch Vehicles Will Make Space Solar Power Affordable

About 20 years ago, NASA conducted a study of space solar power. A friend of mine who was involved said they determined that about six miracles were necessary to make it feasible, the most important being affordable transportation to orbit. Looks like that miracle is coming closer. Reusable launch vehicles now being developed — along with other advancements over the past two decades — could finally make beaming power down […]
