Prospects for Geological Sequestration

Sequestration research up to the present time indicates that between subterranean and sea-bottom options, there is adequate capacity for sequestration of all foreseeable CO2 emissions from fossil fuel production, provided that we invest sufficiently in facilities to separate and sequester it. The risk associated with sequestration, both from leakage under ordinary conditions and from seismic […]

Definition of Solar Geometric Terms and Calculation of Sun’s Position by Time of Day

In the preceding section, we considered sunlight traveling through the atmosphere, without necessarily considering the effect of the sun’s position in the sky on the amount of energy available. In this section, we introduce several other terms used to discuss solar geometry, and then chart the sun’s position in the sky as a function of […]
