The prospect of making trash useful is always fascinating to me. Whether it’s used batteries, solar panels, or spent nuclear fuel, getting use out of something destined for disposal sounds like a win all around. In nuclear energy, figuring out what to do with waste has always been a challenge, since the material needs to […]

The race to prevent the worst wildfires has been an increasingly high-tech one. Companies are proposing AI fire detection systems and drones that can stamp out early blazes. And now, one Canadian startup says it’s going after lightning. Lightning-sparked fires can be a big deal: The Canadian wildfires of 2023 generated nearly 500 million metric
How much wildfire prevention is too much? Read More »
On June 1, 2023, as a sweltering heat wave baked Quebec, thousands of lightning strikes flashed across the province, setting off more than 120 wildfires. The blazes ripped through parched forests and withered grasslands, burned for weeks, and compounded what was rapidly turning into Canada’s worst fire year on record. In the end, nearly 7,000

When a company claims to have created what’s essentially the holy grail of batteries, there are bound to be some questions. Interest has been swirling since Donut Lab, a Finnish company, announced last month that it had a new solid-state battery technology, one that was ready for large-scale production. The company said its batteries can
This company claims a battery breakthrough. Now they need to prove it. Read More »
Every year, poachers shoot hundreds of rhinos, fishing crews haul millions of sharks out of protected seas, and smugglers carry countless animals and plants across borders. This illegal activity is incredibly hard to disrupt, since it’s backed by sophisticated criminal networks and the perpetrators know that their chances of being caught are slim. With an

The United States and the European Union grew into economic superpowers by committing climate atrocities. They have burned a wildly disproportionate share of the world’s oil and gas, planting carbon time bombs that will detonate first in the poorest, hottest parts of the globe. Meanwhile, places like the Solomon Islands and Chad—low-lying or just plain
