And here’s why spiral-welded wind turbine towers are going to be impactful: Keystone says it can make the lightest, lowest-cost, and most structurally optimized towers in the wind turbine industry.

It uses spiral welding techniques to roll sheet steel into huge turbine towers on-site, ... This first product is an 89-m (292-ft) spiral-welded tower for GE's 2.8-127 turbine.

World's First Spiral-welded Wind Turbine Tower is Now Up and Running in the US The plant can produce around 1GW towers at full capacity. By Jace Dela Cruz Published: Feb 27 2023, 09:05 AM EST .

The turbine is expected to generate about 40,000 kilowatt-hours per year, roughly the amount of energy needed to power four homes, Indians officials said. The ballpark uses about 17 million ...

Keystone Tower Systems then worked with wind turbine OEMs to design a commercial-scale tower ready for installation. GE Renewable Energy will employ the first tower produced at the engineer’s new ...

Over at Wired, they calculated the conditions that led to this spiral smoke pattern by modeling one of the turbine blades with VPython. Wind turbines are not supposed to spin this fast.

Keystone Tower Systems, aided by more than $7 million in funding from the U.S. Department of Energy, solved these issues with a spiral welding technique previously used to make steel pipelines.
