Why a Climate Startup Is Building the World’s Biggest Airplane

Radia is a $1 billion climate tech startup with an unusual pitch: It is trying to build the world’s largest airplane. Its proposed aircraft, the Radia Wind Runner, would be as long as a football field, nearly as wide as a New York city block, and capable of carrying 12 times the volume of a Boeing 747. Such a plane could ferry massive wind-turbine blades, unlocking what the company calls “gigawind” — the ability to build offshore-sized wind farms on land.

In this week’s episode, Rob and Jesse talk to Radia’s chief executive officer, Mark Lundstrom. (Jesse’s consulting firm did some research for Radia while it was in stealth mode, in 2020 and 2023.) We discuss why the world needs a bigger plane, how such a new aircraft gets licensed, and why massive wind turbines could be such a big deal for renewable electricity. Shift Key is hosted by Robinson Meyer, executive editor of Heatmap, and Jesse Jenkins, a Princeton professor of energy systems engineering.
