Scientists have discovered a way to store the Sun’s energy in rocks and convert the heat into electricity. Using an approach called concentrated solar power, a team of researchers from Tanzania found that certain granite and soapstones could store solar heat at a sufficiently high density to serve as a primitive form of battery. Thermal energy storage has been touted as a low-cost way of storing and harvesting energy from the Sun, even when it’s no longer shining. Last year, scientists from Sweden and China came up with a way to store solar energy for nearly two decades using an ultra-thin chip, which serves as a thermoelectric generator. The innovative system could technically be integrated into electronics, however it remains too costly to implement at scale. By contrast, the granite and soapstone samples offer a low cost and readily available method of storing solar energy, the researchers said. “Using rocks as a storage medium offers the potential of affordability due to the abundance and low cost of rocks,” the researchers noted in a paper outlining their findings. “An air-rock bed has low investment cost, high reliability and efficiency, is environmentally friendly, and does not require the use of heat exchangers.” The rock bed captures and collects solar thermal energy up to 600 °C, which is then used to boil liquid into steam that powers a generator turbine to produce electricity. The results were detailed in a study, titled ‘Experimental Investigation of Soapstone and Granite Rocks as Energy-Storage Materials for Concentrated Solar Power Generation and Solar Drying Technology’, published by the American Chemical Society. Other thermal energy storage systems have focussed on salt and water, with researchers at Eindhoven University of Technology unveiling a heat battery last year that they claim could work at scale. Rather than capturing heat from the Sun, the system instead collects industrial residual heat. “While the potential is great, we have also seen many great potential technologies that have not made it,” the scientists said at the time. “So we’re going to keep our feet on the ground and take this one step at a time.” Read More Scientists break world record for solar power window material Scientists smash world record for solar power window material Nasa holds urgent meeting about sightings of UFOs Opinion: The real reason companies are warning that AI is as bad as nuclear war

France’s ban of iPhone 12 sales due to radiation fears could have Europe-wide implications, regulators in Belgium, Germany and the Netherlands have warned. Apple will have to recall all iPhone 12 phones in France if corrective updates do not work, the country’s National Frequency Agency (ANFR) said on Tuesday, after tests revealed electromagnetic radiation that was 40 per cent above the legal limit. On Wednesday, the Dutch digital watchdog said it was looking into the ANFR report and is seeking an explanation from the US tech giant. “A norm has been exceeded. Fortunately, there is no acute safety risk but we will very shortly have a talk with producer,” Angeline van Dijk, an inspector with the Nederlandse Rijksinspectie Digitale Infrastructuur (RDI), told the Dutch newspaper Algemeen Dagblad. “The Netherlands attaches as much importance as France to safe use of mobile phones. Mobile phones must comply with European norms.” Belgium and Germany followed with statements of their own on Thursday, with network regulators saying that the French procedure could have a guiding function for the whole of Europe. The Independent has reached out to Apple for comment. Jean-Noel Barrot, France’s junior minister for digital economy, said on Tuesday that the ANFR’s data would be shared with other EU member states, potentially leading to a “snowball effect” for Apple. “Apple is expected to respond within two weeks,” he told the French newspaper Le Parisien. “If they fail to do so, I am prepared to order a recall of all iPhones 12 in circulation. The rule is the same for everyone, including the digital giants.” The iPhone 12 series of smartphones were already set to be discontinued following the unveiling of the iPhone 15 on Tuesday, meaning any sales ban would not have a significant impact on Apple’s phone sales. A continent-wide recall would have considerable implications for the world’s richest company, however, if a solution is not found.
