British invention moves solar power station in space a step closer

Times19-05-2025

For more than eight decades, the idea of beaming an around-the-clock supply of solar power from space has fascinated people including Isaac Asimov, the science-fiction writer, and forward-thinking politicians.
However, while the price of solar panels has dropped drastically and the technology to wirelessly transmit power has improved, a crucial question has still to be answered: how do you build a large solar plant in the Earth's orbit?
Space Solar, a British company, may have the answer. It hopes to assemble a power station in space using autonomous robots. To show that the idea is more than wishful thinking, it has tested the technology at a facility near Oxford.
The business, based in Didcot and backed by more than £10 million of government grants, aims

China surpasses German engineering with world's tallest wind turbine

Other countries compete to build the tallest skyscraper, or the biggest Ferris wheel. China and Germany are more serious about their engineering: they compete for the prize of having the biggest wind turbine. One of China's two leading wind turbine companies, Dongfang Electric, announced on Friday it had completed a key test on the latest machine that, when it goes into service shortly, will break that record. Standing 340 metres from its base in the Pacific, off the coast of the country's Fujian province, to the tip of its blades when they rotate to their highest points, it will be the first wind turbine to be taller than the Eiffel Tower. Dongfang — meaning the East — said it had finished load testing a prototype blade for the turbine, itself 150 metres long. 'We're harnessing the power of tech to plant the seeds of a greener future,' it said in celebration. 'Every blade carries a low-carbon dream, ready to catch the wind and grow strong.' China under President Xi has put huge economic weight on not only an ever-expanding industrial base but also being at the forefront of green technologies. With no room for political opposition, and a heavy continuing reliance nationally on coal and other fossil fuels at the same time, there is little of the public debate around wind power that western European companies have faced. China already makes more than 80 per cent of the world's solar panels. Its low cost base — unfairly subsidised, according to western rivals — is also undercutting and starting to dominate American and European production in wind power too. A worker at the Dongfang factory operates a robotic arm At present the wind turbine claimed to be the world's highest was constructed by another Chinese company, Mingyang, and operates off the southern Chinese island of Hainan. Its hub is at the same height as Dongfang's — 185 metres off the ground — but its blades are a few metres shorter. A similarly sized turbine is already operating at the site to which the Dongfang blades are believed to be heading, the Fujian Fuzhou Offshore Wind Power Industrial Park. Its maximum capacity is 18MW of electricity, and the Hainan turbine is 20MW, which the new turbine will surpass by 6MW. According to estimates, that will be enough at average 10 metres per second windspeeds to power 55,000 homes on its own. Britain's tallest wind turbines — at the Longhill Burn Wind Farm in West Lothian, Scotland — stand up to 150m tall. The blades reach as high as 200m. How long any of these three monsters maintain their dominance is unclear. As Germany tries to reclaim its traditional global leadership in engineering — and tries to stave off Chinese competition — its companies are also building higher. A turbine being designed and built by Gicon, a German conglomerate, will stand at 363 metres from toe to the tip of the vertical blade. It, however, is based on a novel design, in which smaller blades rotate from a 300-metre high lattice structure itself influenced by the design of the Eiffel Tower. It will, however, be the second highest man-made object in Germany, after the Berlin TV Tower.

UK government signals it will not force tech firms to disclose how they train AI

Campaigners have accused ministers of lying to parliament and the creative industries after the government signalled it would not force AI companies to disclose how they train their models. Ministers are holding firm in a standoff with the House of Lords, which has called for artists to be offered immediate copyright protection against artificial intelligence companies. Peers voted by 221 to 116 on Wednesday to insist on an amendment to the data bill that would force AI firms to be transparent about what copyrighted material they use to train their models. In an amendment tabled on Friday, the government dismissed the Lords' request and reiterated its promise to publish an economic impact assessment and technical reports on the future of AI and copyright regulation. Beeban Kidron, the cross-bench peer and film director who has campaigned on behalf of the industry, said during Wednesday's debate that she would 'accept anything that the Commons does' after this week. 'I will not stand in front of your Lordships again and press our case,' she said. But the News Media Association (NMA), which represents publishers including the Guardian, said peers could table further amendments to the data bill when it returns to the Lords next Wednesday. Industry figures said the government was acting in bad faith by not addressing the Lords' concerns and called for it to make further amendments of its own before MPs vote on it on Tuesday. Kidron said: 'The government has repeatedly taken all protections for UK copyrights holders out of the data bill. In doing so they have shafted the creative industries, and they have proved willing to decimate the UK's second biggest industrial sector. They have lied to parliament, and they are lying to the sector.' She said the government's action 'adds another sector to the growing number that have an unbridgeable gap of trust with the government'. Owen Meredith, chief executive of the NMA, said: 'the government's refusal to listen to the strong view of the Lords … risks undermining the legislative process. 'There is still time for the government to do the right thing, and take transparency powers in this bill. This would be a key step towards rebuilding trust with a £126bn industry.'

Opponents of the plans have warned that even if the attempts to insert clauses into the data bill fail, the government could be challenged in the courts over the proposed changes. The consultation on copyright changes, which is due to produce its findings before the end of the year, contains four options: to let AI companies use copyrighted work without permission, alongside an option for artists to 'opt out' of the process; to leave the situation unchanged; to require AI companies to seek licences for using copyrighted work; and to allow AI firms to use copyrighted work with no opt-out for creative companies and individuals. Kyle has said the copyright-waiver-plus-opt-out scenario is no longer the government's preferred option, but Kidron's amendments have attempted to head off that option by effectively requiring tech companies to seek licensing deals for any content that they use to train their AI models.
