The Helios Horizon has completed what its developers call the first crewed, fixed-wing flight powered by solid-state batteries. New Atlas reports: On June 5, test pilot Miguel Iturmendi lifted off from Zephyrhills Municipal Airport in Florida at the controls of the Helios Horizon -- the first crewed, fixed-wing aircraft ever to fly on solid-state batteries. The flight was neither spectacular in distance nor in duration -- it was a series of short tests to validate the aircraft's weight and balance after the new batteries had been installed -- but it didn't need to be to make history. [...] The Helios Horizon's previous lithium-ion pack delivered 260 Wh/kg (watt-hours per kilogram, a measure of how much energy a battery holds relative to its weight). The new solid-state cells hit 410 Wh/kg, a 60% jump. Chief test pilot and company founder Miguel Iturmendi expects that figure to grow another 40% within two years.

Though the battery pack can be topped up over any AC outlet, no special infrastructure needed, fast-charging is also supported for up to 80% capacity in under 15 minutes. The aircraft also recovers energy in flight through wing-mounted solar panels and a regenerative system that spins the propeller as a wind turbine during glides and descents. "Regenerative flight can significantly extend the aircraft's range," Iturmendi said after the test flights.

The Helios Horizon itself started life as a Pipistrel Taurus motorized glider. Iturmendi's team added proprietary battery management, a custom propulsion stack, thermodynamic controls, and solar panel wing extensions. The aircraft already holds the world altitude record for electric planes in its weight class, having reached 24,000 ft (7,315 m). The next goal is 40,000 ft (12,192 m), commercial cruising altitude, in stratospheric flights planned for later this year.

The team behind the AI Octopus Euro 2024 predictor has updated its simulator for the 2026 FIFA World Cup, this time allowing users to throw natural-language scenarios at the model and see how the tournament might shake out. "Sensible questions work – a red card, a key injury, a heat wave, a squad switching base camp – but so do the daft ones, e.g. 'What if the tournament were played with rugby rules?'" said Luzmo CTO and co-founder Haroen Vermylen. The system is simple: enter a scenario in a prompt box, and the predictor spits out how the results might go. The raw data includes squad quality based on player information, heat and altitude factors, injury data, and so on. A Monte Carlo simulation of the tournament is used to generate win/lose/draw probabilities, and the score line is derived from 5,000 match runs. The engine behind the Euro 2024 AI Octopus was written in TypeScript. This time around, the team used Rust. "We moved to Rust to also be able to run things more quickly, as now there is a real-time component to this," Vermylen told The Register. "Before it could run for five minutes or so. Now we want the predictions to actually come out within two to three seconds of actual simulation time." OpenAI models parse the request and generate summaries, and an agent is used to create or transform scenarios, call the calculation engine, answer questions, and so on. A user doesn't need to be a data scientist to ask questions and understand the answers. It's certainly rapid, recalculating the results based on suggested scenarios (even one in which we pondered the effect of politically dubious emissions from a certain world leader). Not that all scenarios will work. Vermylen told us that filtering was in place to ignore profanities and "to avoid scenarios that would just be harmful to certain groups." And then there is the age-old issue of an AI parser simply not understanding the prompt. Clarity is key. Using natural language is a great alternative to a UI with settings and sliders, but that ease of use can result in misunderstandings. As the tournament progresses, the data will be refined. At the time of writing, the baseline reckons that Spain will beat England in the final. Spain currently has an 18 percent chance of lifting the trophy and a 26.8 percent chance of reaching the finals. Those figures can, of course, be altered by feeding in scenarios. For example, we asked: "What if the Spanish team eats a bad paella?" Spain's chance of winning the tournament then dropped to 1.5 percent, with France as the projected champion. We also asked it what would happen if we replaced the England team with Register writers. Suffice to say that scenario did not end well. We asked Vermylen what was next. "The Olympics would be nice… or the Eurovision. We'd like to give the United Kingdom a win." ®

• Group 2: Scotland, 161-5, beat Ireland, 121, by 40 runs

• Kathryn Bryce struck 60 from 39 balls

Scotland notched up a historic maiden World Cup win on Saturday, coming out on top against Ireland by 40 runs. The Scotland captain, Kathryn Bryce, struck a powerful 60 from 39 balls and followed it up with a brilliant one-handed caught-and-bowled to see off Alana Dalzell in the first over of Ireland’s chase.

It was an emotional occasion for the 28-year-old Kirstie Gordon, who switched allegiance back to her native Scotland this year after playing a handful of internationals for England in 2018-19. Gordon had been in tears before play as Flower of Scotland rang out around the ground, but she was all smiles three hours later after returning figures of three for 16.
