Sayan Biswas is a Saint Paul, Minnesota, entrepreneur with leadership in sustainable energy development and commercialization. Sayan Biswas launched TerraCare Energy, LLC, in Saint Paul in 2025, after working since 2022 on building and validating a scaled SkyWindFarm prototype. This innovative modular airborne wind energy system operates at up to 5,000 feet in altitude and meets the needs of data centers and other energy-intensive rural, off-grid systems.
Mr. Biswas earned his doctorate in aerospace engineering at Purdue University and took first place in Combustion Art in 2015 at the 9th US National Combustion Meeting. He was a fellow and scholar at the Institute on Environment and at the Center for Transportation Studies in Minneapolis from 2022 to 2025. His focus was on creating a hydrogen hub that enabled the production of aviation fuel through sustainable green hydrogen. He also developed strategies for minimizing methane emissions associated with natural gas flaring across the Bakken and Permian basins.
As a postdoctoral researcher in energy and combustion at Sandia National Laboratories in Livermore, California, Sayan Biswas developed a next-generation plasma igniter that took the place of conventional spark plugs and boosted fuel economy by 20 percent. He has earned American Society of Mechanical Engineers recognition as a “Rising Star of Mechanical Engineering.”
