For almost a decade, Radia, a company based in Boulder, Colo., has been working on developing what would be the world’s largest plane, one that it said would have a dozen times the cargo volume of a Boeing 747.

Radia’s WindRunner aircraft would solve a crucial problem for the wind power industry. Giant wind turbine blades are more efficient, but often can’t be easily shipped across aging roads and bridges.

But the industry is now facing an even bigger problem: President Trump’s antipathy toward wind power. Trump has called the wind sector “garbage,” and right after entering office he issued an executive order aimed at curbing wind power’s expansion. And Trump’s tariffs could also raise costs for the wind industry.

Mark Lundstrom, Radia’s chief executive officer, doesn’t see Trump as that big of a threat to his company. The biggest wind turbines, he said, allow wind projects to generate energy more consistently. This version of wind power, Lundstrom argues, fits with “where the administration wants to go in terms of getting closer to base load with all energy sources.”
