Insect swarms might generate as much electric charge as storm clouds
Honeybees flying over a sensor measuring atmospheric voltage sparked a look into how insect-induced static electricity might affect the atmosphere.
- Climate
Wind turbines could help capture carbon dioxide while providing power
Turbulent wakes from wind turbines can concentrate CO2 from cities and factories, making it easier to remove the greenhouse gas from the atmosphere.
