Inexpensive Device Harvests Energy From A Light Breeze
October 12, 2022 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Nanyang Technological University scientists have developed a low-cost device that can harness energy from wind as gentle as a light breeze and store it as electricity. When exposed to winds with a velocity as low as two meters per second (m/s), the device can produce a voltage of three volts and generate electricity power […]

New Operating Method Improves Wind Turbine Farm Output
August 16, 2022 | Leave a Comment
Both MIT and CalTech have press releases out explaining research that could increase wind turbine output by more than 1% up to 3%. The new technology is based on an algorithm that forces individual turbines to coordinate with the others thus boosting the total output. The new approach models the wind flow of the entire […]

How To Restart A Grid Full Of Wind Turbines
July 6, 2022 | Leave a Comment
An Iowa State University team is now working to develop strategies and controllers that would reenergize power grids dominated by wind power. When electric grids go down, there’s no way to restore them – ‘blackstart’ them – with power from wind turbines. In Iowa, wind turbines now produce 55% of the state’s electricity. It used […]
