He cleaned a lagoon… with bubbles Meet Marino Morikawa, a Peruvian nanoscientist. When his father called to say the lagoon of his childhood—El Cascajo—had become a dump, Marino left his lab in Japan and flew home. Using ultra-fine nanobubbles (≈50–100 nm) made with hardware-store parts, he built a natural, chemical-free system that traps pollutants and bacteria: Inject nanobubbles into the water As they rise slowly, their ionic charge attracts contaminants Biofilters with nati...

This city ski slope heats and powers 150,000 people—by burning their trash. It sits on top of Copenhagen’s waste-to-energy plant, CopenHill. In the late 2000s, the city wanted to shut down coal but still had 440,000 tons of non-recyclable waste to deal with every year. Instead of burying or exporting it, they turned it into energy. The challenge: build an incinerator that’s clean, efficient, and embraced by locals. Danish architects BIG—Bjarke Ingels Group proposed something radical: make i...

In Georgetown (USA), a full 3D-printed neighborhood is coming online—fast. Not a concept render: real homes, printed on-site, then finished with solar + smart energy controls. Why it mattersSpeed: printed in about 3 weeks for the shell phaseLess waste: additive construction = minimal material offcutsEnergy positive potential: solar panels + smart thermostats to shrink bills and emissionsRepeatable: scalable playbook for resilient, affordable housingClimate & circularity3D printing cuts co...

These giant meshes turn fog into drinking water—no pumps, no power. It’s CloudFisher, a system developed by the German NGO WasserStiftung that captures airborne moisture with technical plastic nets stretched into the wind. How it works Zero energy: wind + fog, no electricity required Durable & recyclable: engineered to resist winds up to 120 km/h Potable by design: collected water is filtered to WHO standards, then routed to public fountains or cisterns Why it matters In Moroc...

👋 Imagine a giant vacuum cleaner — but instead of dust, it’s pulling carbon dioxide straight out of the sky. It’s called Direct Air Capture (DAC), and it’s no longer science fiction. Real plants are running today in Iceland, Texas, and California. In this episode of Reactor, we break down: 🌬️ How Direct Air Capture actually works — step by step 🧪 The four main DAC technologies (solids, liquids, minerals, electrochemicals) ⚡ Why DAC is only possible now (cheap renewables, better materials...

💧☀️ In Australia, 1 trillion litres of water vanish every year — lost to evaporation. But what if the solution was simple… and powerful? Floating solar panels are changing the game. They shade reservoirs, cutting water evaporation by up to 50%, *while also generating clean electricity*. Even better, the cool water underneath helps the panels work more efficiently than land-based solar farms. That means: ✅ Saving billions of litres of water every year ✅ Powering homes, farms, and even hy...

From the ice rink to the fight against climate change. Brent Story once wore the jersey for Team Canada in hockey. Now he’s leading EmitiQ — a company making sustainability simpler for businesses around the world. Instead of endless reports and confusing rules, EmitiQ helps companies: ✔️ Measure emissions automatically ✔️ Follow climate rules correctly ✔️ Work with suppliers to cut carbon at the source Because climate action shouldn’t be complicated — it should be possible. 👉 Watch how one at...

What if tomorrow’s clean energy came from yesterday’s nuclear waste? In this episode, we explore Hexana, a French deep tech startup developing a next-generation small modular reactor (SMR) designed to decarbonize heavy industries like steel, chemicals, and even green hydrogen production. Hexana’s sodium-cooled fast reactor doesn’t just generate high-temperature heat and clean electricity—it also burns nuclear waste, including depleted uranium and recycled plutonium, dramatically reducing high...

5G from Space: How Constellation Is Connecting the Disconnected What if you could stream Netflix from the middle of the Sahara—thanks to 5G from space? In this episode, we explore the bold vision of Constellation Technologies, a Paris-based startup building a low-orbit satellite network to deliver fiber-like 5G speeds anywhere on Earth. Founded by former World Black engineer Charles Delfieux, Constellation is launching tiny satellites in very low Earth orbit (VLEO) to bring fast, reliable, ...

Drones That Defy Physics: Inside Aerix’s Omnidirectional Revolution What if a drone could flip upside down, spin in place, and hold steady in a 100 km/h storm? In this episode, we explore the mind-blowing innovation of Aerix Systems, a French deep tech startup founded in 2020 by two engineering students in Gironde. Aerix has developed the world’s first omnidirectional propulsion system—think drone engines mounted on gimbals that let it thrust in any direction. Their modular platform, the M1...

In this episode, we dive into the story of e-Taranis, a French cleantech startup based in the Basque Country that's aiming to democratize wind power for everyday households. Their innovation, Alaé, is a compact, ultra-quiet, and eco-friendly wind turbine designed specifically for urban and suburban homes. Unlike traditional turbines, Alaé starts producing clean energy at wind speeds as low as 10 km/h, making it practical even in less windy regions. It’s built with 97% recyclable materials, bl...

Purifying the Planet with Chemistry: The Exposome Story In this episode, we explore the story of Exposome, a rising cleantech startup based in Mumbai. Founded in 2020 by Prerna Santaliagoradiya, Exposome is pioneering the use of smart materials and molecular chemistry to clean industrial air and water. Their breakthrough products—like PureSafe and PureAnion—are tackling pollutants at the source, serving industries from oil & gas to pharmaceuticals and renewables. We also delve into Exposo...
