A new experiment demonstrates that commercial solar farms in space could one day be possible, according to the researchers behind it. Scientists from the UK say that a satellite launched into space to test the opportunities to gather sunlight for power has shown more success than expected. The experiment showed that it was possible to make lightweight solar panels at low cost that would be able to work in space, researchers said. They sent one of those units into space and examined how it worked over a period of six years and 30,000 orbits. It was able to withstand the solar radiation and other damage of space, they said, and continue generating power. “We are very pleased that a mission designed to last one year is still working after six. These detailed data show the panels have resisted radiation and their thin-film structure has not deteriorated in the harsh thermal and vacuum conditions of space,” said Craig Underwood from the University of Surrey, “This ultra-low mass solar cell technology could lead to large, low-cost solar power stations deployed in space, bringing clean energy back to Earth – and now we have the first evidence that the technology works reliably in orbit.” The panels were made at the University of Swansea, and used a new kind of solar cell made out of cadmium telluride. That material allows for larger panels at lighter weights, which provide more power and are relatively cheap. Colleagues at the University of Surrey then built those panels into a satellite that could be delivered to space, as well as the technology to measure how they continued to perform once they were in orbit. Those measurements showed that the panels gradually became less efficient, but researchers say they nonetheless showed that the panels could eventually be commercially viable. Solar farms in space would overcome many of the problems with existing renewable infrastructure on Earth. The solar farms could allow for more space on the ground, but more notably would be able to avoid issues caused by weather and benefit from more intense sunlight than there is on the surface. Making units that are able to withstand the difficulties of space is just one of a number of challenges for solar farms in space. There would also need to be a way to get the energy back down to us, for instance – though this summer researchers were able to successfully beam power down to Earth using microwaves. A study describing the findings, ‘IAC-22-C3.3.8 Six years of spaceflight results from the AlSat-1N Thin-Film Solar Cell (TFSC) experiment’, is published in the journal Acta Astronautica.

Barnsley have been expelled from the FA Cup for fielding an ineligible player in their first-round replay against Horsham. Seventh-tier Horsham will now progress to round two, where they will visit League Two strugglers Sutton. The Tykes were 3-0 winners in last Tuesday’s replay, after the first game had finished 3-3 at Oakwell, but have since acknowledged a “regrettable”, “unintentional” error that has seen them kicked out of this season’s competition by the Football Association. A club statement read: “Today the FA has advised us that we will no longer be able to participate in the FA Cup this season. “An administrative error was brought to our attention regarding the eligibility of a player who played in last Tuesday’s game with Horsham FC. “The club has fully co-operated with the investigation and has accepted the FA’s decision. We have been in contact with Horsham FC and would like to thank the club and chairman for their understanding and co-operation throughout this process. “We would like to apologise to our fans, players and staff for this regrettable error. “This mistake – although unintentional – falls way below the high standards we set at this club and is simply not what you deserve. “We have already conducted a full internal investigation and have subsequently put safeguards in place to ensure this will never happen again.” The FA said Barnsley fielded a player in the replay who was not eligible for the first match, which is against the rules. Forward Aiden Marsh was on loan at National League York when the first game took place on November 3, before being recalled by parent club Barnsley on November 6 and playing 71 minutes of the replay on November 14. “A Professional Game Board sub-committee has removed Barnsley from the 2023-24 Emirates FA Cup for fielding an ineligible player during their first-round proper replay against Horsham on Tuesday 14 November 2023,” an FA statement read. “The FA alleged that the player was ineligible for this replay, as he was not correctly registered and eligible for the original first-round-proper match on Friday 3 November 2023, which constitutes a breach of FA Cup rule 103. “Barnsley admitted this charge and acknowledged that the breach had occurred. The sub-committee’s members ordered that Barnsley be removed from the competition, and that Horsham be awarded the tie and progression to the second round proper. “Subject to any appeal by Barnsley, Horsham will now play away to Sutton United in the Second Round Proper on Saturday 2 December 2023.” Read More Great Britain determined to ruin Novak Djokovic’s astonishing year at Davis Cup Everton have extra motivation following points deduction – director of football What happens next for Wales as they look to book a place at Euro 2024?
