Will Better Superconductors Transform the World?


Peter Greenwood for Quanta Magazine

Scientists are pursuing materials that can conduct electricity with perfect efficiency under ambient conditions. In this episode, the physicist Siddharth Shanker Saxena tells co-host Janna Levin about what makes this hunt so difficult and consequential.

If superconductors — materials that conduct electricity without any resistance — worked at temperatures and pressures close to what we would consider normal, they would be world-changing. They could dramatically amplify power grids, levitate high-speed trains and enable more affordable medical technologies.

For more than a century, physicists have tinkered with different compounds and environmental conditions in pursuit of this elusive property, but while success has sometimes been claimed, the reports were always debunked or withdrawn. What makes this challenge so tricky?…Story continues….
