Pioneering teenagers win acclaim for invention that could change the future of clean water: 'We'll refine our prototype'
Two European teens have won a prestigious prize for their invention, which could change the future of clean water.
Earlier this month, Tomáš Čermák, an 18-year-old from the Czech Republic, and Anna Podmanická, a 19-year-old from Slovakia, were named the European winners of The Earth Prize. The two were recognized for their invention, PURA, which uses light and plasma to purify wastewater.
As Tech.EU writes, PURA is an "energy-efficient, cost-effective solution [that] could transform water purification and ensure a healthier future."
Podmanická's research specializes in water purification using photocatalysis, in which light sets off a chemical reaction that breaks down organic matter at a molecular level, leaving water and carbon dioxide behind. Čermák researches how cold plasma can destroy pollutants and bacteria, and they combined their specialties to create PURA.
Tech.EU reports that PURA is already working on a small scale, removing impurities from wastewater and making it suitable for drinking water and other household uses.
"Our next step is to scale PURA," Cermak said in a video accepting the award. "We'll refine our prototype, test it in real-world conditions, engage students, and work with policymakers to lay groundwork for this new technology."
Finding an affordable way to bring clean water to all people would truly change the world. The United Nations estimates that 2 billion people, or roughly 25% of the world's population, don't have access to clean drinking water. And recent studies show that PFAS, or "forever chemicals," are prevalent in drinking water globally.
The Earth Prize is an international competition, awarding teenagers who develop solutions that move the world toward environmental sustainability. Each of the seven regional winners, such as Čermák and Podmanická, receives $12,500 to help implement their idea.
A public vote determines the global grand champion, with the winner announced in late April. Previous projects from the competition include an AI-powered wildfire sensor, a tool that helps predict flood patterns, and technology that uses plasma to boost crop yields and create eco-friendly fertilizer.

Nvidia chief calls AI ‘the greatest equalizer' — but warns Europe risks falling behind
PARIS (AP) — Will artificial intelligence save humanity — or destroy it? Lift up the world's poorest — or tighten the grip of a tech elite? Jensen Huang — the global chip tycoon widely predicted to become one of the world's first trillionaires — offered his answer on Wednesday: neither dystopia nor domination. AI, he said, is a tool for liberation. Wearing his signature biker jacket and mobbed by fans for selfies, the Nvidia CEO cut the figure of a tech rockstar as he took the stage at VivaTech in Paris. 'AI is the greatest equalizer of people the world has ever created,' Huang said, kicking off one of Europe's biggest technology industry fairs. Huang's core argument: AI can level the playing field, not tilt it. Critics argue Nvidia's dominance risks concentrating power in the hands of a few. But Huang insists the opposite — that by slashing computing costs and expanding access, 'we're democratizing intelligence' for startups and nations alike. But beyond the sheeny optics, Nvidia used the Paris summit to unveil a wave of infrastructure announcements across Europe, signaling a dramatic expansion of the AI chipmaker's physical and strategic footprint on the continent. In France, the company is deploying 18,000 of its new Blackwell chips with startup Mistral AI. In Germany, it's building an industrial AI cloud to support manufacturers. Similar rollouts are underway in Italy, Spain, Finland and the U.K., including a new AI lab in Britain. Other announcements include a partnership with AI startup Perplexity to bring sovereign AI models to European publishers and telecoms, a new cloud platform with Mistral AI, and work with BMW and Mercedes-Benz to train AI-powered robots for use in auto plants. The announcements underscore how central AI infrastructure has become to global strategy — and how Nvidia, now the world's most valuable chipmaker, is positioning itself as the engine behind it. As the company rolls out ever more powerful systems, critics warn the model risks creating a new kind of 'technological priesthood' — one in which only the wealthiest companies or governments can afford the compute power, energy, and elite engineering talent required to participate. That, they argue, could choke the bottom-up innovation that built the tech industry in the first place. Huang pushed back. 'Through the velocity of our innovation, we democratize,' he said, responding to a question by The Associated Press. 'We lower the cost of access to technology.' As Huang put it, these factories 'reason,' 'plan,' and 'spend a lot of time talking to' themselves, powering everything from ChatGPT to autonomous vehicles and diagnostics. But some critics warn that without guardrails, such all-seeing, self-reinforcing systems could go the way of Skynet in ' The Terminator ' movie — vast intelligence engines that outpace human control. To that, Huang offers a counter-model: layered AI governance by design. 'In the future,' he said, 'the AI that is doing the task is going to be surrounded by 70 or 80 other AIs that are supervising it, observing it, guarding it, ensuring that it doesn't go off the rails.' He likened the moment to a new industrial revolution. Just as electricity transformed the last one, Huang said, AI will power the next — and that means every country needs a national intelligence infrastructure. That's why, he explained, he's been crisscrossing the globe meeting heads of state. 'They all want AI to be part of their infrastructure,' he said. 'They want AI to be a growth manufacturing industry for them.' Europe, long praised for its leadership on digital rights, now finds itself at a crossroads. As Brussels pushes forward with world-first AI regulations, some warn that over-caution could cost the bloc its place in the global race. With the U.S. and China surging ahead and most major AI firms based elsewhere, the risk isn't just falling behind — it's becoming irrelevant. Huang has a different vision: sovereign AI. Not isolation, but autonomy — building national AI systems aligned with local values, independent of foreign tech giants. 'The data belongs to you,' Huang said. 'It belongs to your people, your country... your culture, your history, your common sense.' But fears over AI misuse remain potent — from surveillance and deepfake propaganda to job losses and algorithmic discrimination. Huang doesn't deny the risks. But he insists the technology can be kept in check — by itself. The VivaTech event was part of Huang's broader European tour. He had already appeared at London Tech Week and is scheduled to visit Germany. In Paris, he joined French President Emmanuel Macron and Mistral AI CEO Arthur Mensch to reinforce his message that AI is now a national priority.

Europe, we're not leaving. Period.
There are some headlines making the rounds claiming that TechCrunch is 'pulling out of Europe' and shuttering its coverage of European startups. This is flat-out wrong. It misrepresents who we are, what we do, and — most of all — what we believe. The recent changes at TechCrunch are not about retreat. They are about realignment and reinforcement. This new chapter is fueled by our partnership with our sister company, Foundry, which was brought under the same ownership to create a tech media entity with unparalleled global scope. To be clear, Foundry is a powerhouse of international technology journalism. Its portfolio includes established and respected brands like PCWorld, Macworld, CIO, and TechAdvisor, with a vast network of journalists and deep-rooted expertise in local and regional tech ecosystems across Europe and the world. The suggestion that our new ownership believes international coverage is unessential is patently false. The entire purpose of bringing TechCrunch and Foundry together is to create a stronger, more globally focused media platform. Europe is where fintech regulation is rewritten, where quantum startups spin out of Max Planck labs, where climate-tech pilots become the standard for the rest of the planet. In 2024 alone, European founders raised over €40 billion; many of the unicorns we covered last year were born on this continent. If you care about the future of technology, you have to be here. And we are. As we integrate the strengths of both TechCrunch and Foundry, here is our promise to the founders, investors, and readers in Europe and beyond: To the startup community: Keep your tips, term sheets, and tantrums coming. Send them to tips@ or ping our encrypted channels. We'll be listening — louder and more broadly than ever. TechCrunch isn't retreating from Europe. We're doubling down. — Michael Reinstein, Chairman and Publisher Sign in to access your portfolio

Nvidia (NVDA) to Build First Industrial AI Cloud in Germany
Nvidia (NVDA, Financials) will develop its first industrial AI cloud in Germany to support applications ranging from automotive design to logistics optimization, CEO Jensen Huang said Wednesday at the VivaTech conference in Paris. Warning! GuruFocus has detected 4 Warning Signs with NVDA. The platform will help industrial firms such as BMW and Mercedes-Benz simulate production processes and integrate robotics with artificial intelligence. Biotech companies like Novo Nordisk (NVO, Financials) are also expected to benefit, using Nvidia's tools for drug discovery. Huang said Nvidia will multiply its AI computing capacity in Europe tenfold over the next two years and will open 20 AI factorieslarge-scale infrastructure facilities for building and deploying AI models. He described Europe as newly "awakened" to the importance of sovereign AI development. Nvidia will also expand its technology centers across seven countries, launch a European compute marketplace, and partner with AI startups such as France-based Mistral to run models on 18,000 Nvidia chips. The project aligns with the European Commission's own investment initiative, which earmarked $20 billion in March for building AI factories. Huang emphasized that no country or company can afford to "outsource its intelligence." Separately, Huang reiterated his recent comments that quantum computing is reaching an inflection point and could solve real-world problems within a few years, reversing his prior view that useful quantum systems remain decades away.
