A Process for Capturing CO2 from the Atmosphere

A Process for Capturing CO2 from the Atmosphere

An industrial process for large scale capture of atmospheric CO 2 (DAC) serves two roles. First, as a source of CO 2 for making carbon neutral hydrocarbon fuels, enabling carbon free energy to be converted into high energy density fuels. Solar fuels, for example, may be produced at high insolation low cost locations from DAC CO 2 and electrolytic hydrogen using gas to liquids technology

Thermionic emission

Thermionic emission

Thermionic emission is the thermally induced flow of charge carriers from a surface or over a potential energy barrier. This occurs because the thermal energy given to the carrier overcomes the work function of the material. The charge carriers can be electrons or ions, and in older literature are sometimes referred to as thermions.After emission, a charge that is equal in magnitude and

Pebble Mine (Copper/Gold Prospect) Ground Truth Trekking

Layout. The mineral prospect includes two distinct areas, Pebble West and Pebble East. Pebble West is relatively shallow, and would be a massive open pit mine, almost two miles wide and a few thousand feet deep.The ore in Pebble East is much deeper beneath the surface and would be mined using block caving.This process involves mining the deposit from the bottom upwards, collapsing the ground
