Hugh Herr is a living exemplar of the maxim that the best way to predict the future is to invent it. At the age of 17, Herr was already an accomplished mountaineer, but during an ice-climbing expedition he lost his way in a blizzard and was stranded on a mountainside for three days. By the time rescuers found him, both of his legs were doomed by frostbite and had to be amputated below the knee. Once his scars healed, Herr spent months in rehab rooms trying out prosthetic legs, but he found them unacceptable: How could he climb with such clunky things? Surely, he thought, medical technologists could build replacement parts that wouldn’t slow him down.

New Filter Doubles Nuclear Fuel Extractable from Seawater

It pulls uranium out at record rates—but real-world tests are still to come

The International Atomic Energy Agency expects nuclear power to grow significantly in the coming decades, by up to 82 percent by the year 2050. That would create an increase in demand for uranium that reserves on land may not be able to meet.

But the world’s oceans, according to the U.S. Department of Energy, contain at least 500 times more uranium than in all known terrestrial reserves. That equates to more than 4.5 billion metric tons of the element in seawater, albeit present at an extremely dilute concentration of 3.3 parts per billion, and scientists have been trying to find efficient ways to extract it.
