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.
PARIS (ESA PR) — We urgently need solutions to tackle climate change on Earth. Meanwhile, the space sector is working hard to make space exploration more sustainable. ESA is targeting both ambitions by enabling European academia and industry to take further steps towards space-based solar power (SBSP).
KIRTLAND AIR FORCE BASE, N.M. (AFRL PR) – The Air Force Research Laboratory’s and Northrop Grumman’s Space Solar Power Incremental Demonstrations and Research (SSPIDR) Project have successfully conducted the first end-to-end demonstration of key hardware for the Arachne flight experiment.
A ground demonstration of novel components for the “sandwich tile” were used to successfully convert solar energy to radio frequency (RF) – a fundamental step required to pave the way for a large-scale solar power collection system in space.
PASADENA, August 3, 2021 (Caltech PR) — Today, Caltech is announcing that Donald Bren, chairman of Irvine Company and a lifetime member of the Caltech Board of Trustees, donated over $100 million to form the Space-based Solar Power Project (SSPP), which is developing technology capable of generating solar power in space and beaming it back to Earth.
Solar energy harvested in space offers the potential for an unlimited and constant zero carbon power source
SWINDON, UK (UK Space Agency PR) — The UK government has commissioned new research into space-based solar power (SBSP) systems that would use very large solar power satellites to collect solar energy, convert it into high-frequency radio waves, and safely beam it back to ground-based receivers connected to the electrical power grid.
It is an idea first conjured by science-fiction writer Isaac Asimov in 1941, and is now being studied by several nations because the lightweight solar panels and wireless power transmission technology is advancing rapidly. This, together with lower cost commercial space launch, may make the concept of solar power satellites more feasible and economically viable.
Now the UK in 2020 will explore whether this renewable technology could offer a resilient, safe and sustainable energy source.
Project directly supports the Space Solar Power Initiative converting solar power in space to radio frequency on Earth.
FALLS CHURCH, Va. (Northrop Grumman PR) — Northrop Grumman is working with the U.S. Air Force Research Laboratory (AFRL) on a project to rapidly infuse space technological innovations to incrementally develop component technologies needed for a prototype solar energy collection system.
The project is designed to provide constant, consistent and logistically agile power to expeditionary forces operating in unimproved areas such as forward operating bases. These forces require assured power that will be transmitted via radio frequency (RF) from spacecraft.
WASHINGTON, DC, March 7, 2016 (NSS PR) — The National Space Society congratulates the Space Solar Power D3 (SSPD3) team on sweeping the awards in a March 2 multi-departmental competition to find promising new technology ideas that could simultaneously advance diplomacy, defense and development (D3). The SSPD3 team proposal was titled “Carbon-Free Energy for Global Resilience and International Goodwill.”
WASHINGTON, DC (NSS PR) — The National Space Society (NSS) congratulates the “Space Solar Power D3” team on making it to the winners circle in a Department of Defense (DOD) competition to find promising new technology ideas that could simultaneously advance diplomacy, development and defense. Space Solar Power (SSP) is among only six winners out of 500 entries for the DOD’s first innovation challenge for the D3 (Diplomacy, Development, Defense) Summit.
PASADENA, Calif., April 20, 2015 (Northrop Grumman PR) — Northrop Grumman Corporation (NOC) has signed a sponsored research agreement with the California Institute of Technology (Caltech) for the development of the Space Solar Power Initiative (SSPI). Under the terms of the agreement, Northrop Grumman will provide up to $17.5 million to the initiative over three years.
Washington, DC, June 10, 2013 (NSS PR) — National Space Society (NSS) today announces a new space solar power international initiative. NSS endorses this initiative and will work to forge an international organization involving America, India and other nations to develop space solar power. This has the potential of solving humanity’s energy needs and greatly mitigating climate change.
A new petition on the White House’s website was created today concerning space solar power.
We petition the Obama Administration to: commission a study to determine if Space Solar Power is a viable middle- to long-term solution for energy independence.
Space Solar Power would be extremely expensive to realize. That’s the down side. The up side is it scales indefinitely – once you have a single one Gigawatt SPS power plant installed, the second one costs substantially less. It would create an exponential growth in an energy source with potential long term yield far in excess of the current world consumption of energy. In other words – anything on a planetary surface will run in to yield limits, and fundamentally constraint economic growth.
Anything in space would pose no such constraint. Add one in year one – add two in year two. Add four in year three. That is an exponential output growth. It would solve a LOT of problems, and we need a study making the potential insightful.
PowerSat: Space Solar Flies Closer toÂ Earth Earth2Tech.com
Solar from space: It may sound like a bad sci-fi movie, but a growing number of companies think it could solve the worldâ€™s energy crisis. Among them is Everett, Wash.-based PowerSat Corp., which said today itâ€™s filed a provisional patent for two technologies it claims could help make the transmission of solar power from space more cost-effective.
