Abstract
Methods of geoengineering are provided to create shade by reflecting solar radiation into space to mitigate global warming, as well as reduce storm severity, and other applications. These methods rely on dispersing hollow silicate microspheres into the atmosphere, or into orbit, by aircraft or rocket, where the silicate microspheres can optionally comprise additions of one of boron or sodium, or both. Silicate microspheres manufactured on the Moon can be delivered to Earth or L1 orbit as an alternative to lofting from Earth’s surface. Hollow silicate microspheres are more than 6 times the size of comparable solid SRM particles. This method substantially improves reflectivity, solar-powered lofting, and, in the presence of liquid water aerosols, the greater surface area enables improved carbon dioxide capture.
