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...

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 e...

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 matters Speed: printed in about 3 weeks for the shell phase Less waste: additive construction = minimal material offcuts Energy positive potential: solar panels + smart thermostats to shrink bills and emissions Repeat...

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...

👋 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,...

💧☀️ 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...
