Summary

Story summary

Startups Altaeros and Sawes Energy Technology are developing a new wind energy technology using dirigible designs for consistent power generation.
The airborne turbines operate at 1,000 feet, capturing stronger winds, with Sawes' S1500 prototype generating 1 megawatt of power during tests in Xinjiang, China.
The S1500 is expected to be 40% cheaper to build than conventional turbines, potentially reducing energy costs by 30%.
Challenges include storm management and competition with coal power before commercial deployment can occur.
