“Space-based solar power” (SBSP) sounds great in theory: giant solar farms in space collect unobstructed sunlight 24/7 and beam it to Earth stations, all using technology that already exists. It isn’t getting off the ground (pun intended!) primarily because of the cost of launching thousands of tonnes into space, plus assembly and maintenance. The attraction is that, if it can happen affordably, it could provide a hundred times the energy the … [Read more...]
Solar power stations in space that beam uninterruptible power back to Earth
It’s still on the drawing board, but putting solar farms into orbit has obvious advantages. The power is 24/7, and no sunlight is lost through the atmosphere. But there are two big challenges. Amanda Jane Hughes and Stefania Soldini at the University of Liverpool explain how the European Space Agency, the California Institute of Technology, the Japan Aerospace Exploration Agency, and Xidian University in China, among others, are attempting to … [Read more...]
EU plans first satellite fleet to monitor CO2 in every country
The speed and policies required for a successful transition depend on our ability to measure emissions accurately and globally. That’s why Europe is readying a new fleet of three satellites to monitor CO2 emissions at every point on earth, creating the first worldwide system capable of measuring at city and even power plant level in close to real time, reports Karl Mathiesen at Climate Home News. It will mean, for example, a city can measure how … [Read more...]
