Study: Atmospheric Engineering with Aerosols Could Reduce Effectiveness of Certain Kinds of Solar Power

Green Car Congress

The atmospheric engineering scheme of using sunlight-scattering stratospheric aerosols to combat global warming could reduce the effectiveness of certain kinds of solar power generation systems using parabolic or other concentrating optics.

The Marimba Virtuoso’s Desktop Planetarium

Cars That Think

Traditional orreries were mechanical models of the solar system. These often beautiful and intricate instruments were devised by skilled clockmakers to illustrate how the planets and their moons moved through the solar system. Two years later, the Philippines’ Atomic Energy Commission contributed a siderite, a nickel-iron meteorite.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. The proposal calls for what’s known as “solar geoengineering”: cooling the planet by deflecting sunlight that would otherwise strike the planet.
