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

Twitter is refusing to stand by a $1 billion contract with Google to use its cloud hosting services, according to reports. Elon Musk’s company is in the process of moving away from Google Cloud before the contract expires on 30 June, Platformer reported, leaving the social media firm’s trust and safety teams in peril. The move appears to be part of radical cost-cutting measures that have been underway since Mr Musk’s takeover of Twitter in October 2022, which has already seen thousands of employees laid off and a reduction in infrastructure spending. The deal with Google Cloud relates to hosting services, which include protecting accounts and fighting spam on Twitter. The effort to move to a different platform is reportedly “running behind schedule”, which could potentially impact Twitter’s ability to detect and remove spam and child sexual abuse material. Twitter did not respond to a request for comment – the company’s PR team was effectively eliminated during the lay-offs – while Google is also yet to respond. A separate report from The Information last month claimed that Twitter also delayed payments to Amazon Web Services. The latest issues come after internal documents revealed that Twitter’s advertising revenue is down by more than half since Mr Musk’s takeover. The company’s main revenue stream was initially hit by advertisers withdrawing over concerns related to the direction of the platform and its leadership, though Mr Musk claimed in April that “almost all advertisers have come back or said they are going to come back”. Twitter’s valuation since Mr Musk bought the company for $44 billion has dropped to around $15 billion, according to estimates from investment firm Fidelity. Newly-appointed Twitter chief executive Linda Yaccarino, who took over from Mr Musk last week, has been tasked with improving relationships with advertisers, while Mr Musk focuses on “overseeing product, software and sysops as the firm’s chief technology officer.

Microsoft will keep Call of Duty on PlayStation after it buys the series’ developer, according to a new deal signed with PlayStation. The Xbox and PlayStation makers have been engaged in a sometimes angry war in recent months, as Microsoft attempts to buy Activision Blizzard, the developer of games including Call of Duty. PlayStation’s objections centre around the fact that the deal would give Microsoft too much control over the gaming market, given the dominance of Call of Duty among players on consoles. Those objections have led to legal hearings, as well as opposition from regulators and competition authorities. At times, those legal objections have looked to derail the deal, which would be the biggest ever gaming acquisition if it is completed. But it now looks to be moving forward, after Microsoft announced that it had signed a “binding agreement” to make the games available on other consoles when the deal is complete. The deal could further ease regulators concerns about what would happen to the game as well as the broader console and gaming market if the deal goes ahead. It is the latest piece of good news for Microsoft, which won a legal case last week against objections from the US Federal Trade Commission, and looks to be moving towards closing the deal. “We are pleased to announce that Microsoft and PlayStation have signed a binding agreement to keep Call of Duty on PlayStation following the acquisition of Activision Blizzard. We look forward to a future where players globally have more choice to play their favorite games,” said Phil Spencer, Microsoft’s head of Xbox, in a tweet. And Microsoft President Brad Smith said in a tweet, “Even after we cross the finish line for this deal’s approval, we will remain focused on ensuring that Call of Duty remains available on more platforms and for more consumers than ever before.” The FTC had argued the deal would hurt consumers whether they played video games on consoles or had subscriptions because Microsoft would have an incentive to shut out rivals like Sony. To address the FTC’s concerns, Microsoft had earlier agreed to license “Call of Duty” to rivals, including a 10-year contract with Nintendo, contingent on the merger closing.
