GE installs world’s first spiral-welded wind turbine tower
Spiral-welded wind turbine towers could quietly dissolve one of the biggest barriers holding back wind energy: the highway. Because conventional towers must be trucked in, U.S. road regulations cap their diameter — and therefore their height — well below what the physics of wind actually allows. Keystone’s mobile factories build towers on-site from coiled steel, removing that constraint entirely and making towers tall enough to reach stronger, more consistent winds. One tower doesn’t rewrite the industry, but it proves the concept works. If the approach scales, it could bring competitive wind energy to regions that have never had it.
