Coalbed methane (CBM or coal bed methane), coalbed gas, coal seam gas (CSG), or coal mine methane (CMM) is a form of natural gas extracted from coal beds.

Electric incinerating toilets turn excrement into a small amount of ash.

A coal stove can burn either wood or coal, but a wood stove cannot burn coal unless a grate is supplied.

Clean coal technologies were at least 25 percent more efficient than traditional coal fired power plants.

Unmineable coal seams can be used to store because the molecules attach to the surface of coal.

Hydraulic mortar was not available in ancient China, possibly due to a lack of volcanic ash.

Hansen condemns coal fired power plants as death factories, and his belief that coal is evil is widely shared.

Greater sharing of existing cleaner coal technologies is needed, as is continued development of next generation clean coal plants.

By contrast, burning coal yields only C02.

In the process of absorption the coal releases previously absorbed methane, and the methane can be recovered (enhanced coal bed methane recovery).

Airborne volcanic ash can reflect the Sun's rays back into space and thereby contribute to cooling the planet.

Each volcanic event distributed ash with a unique set of properties (shape and color of particles, chemical signature).

PRINCETON When airports across Europe reopened after the closure caused by the eruption of Iceland s Eyjafjallajökull volcano, it was not because the amount of ash in the atmosphere had dropped, but because the risk that the ash posed to airplane safety had been reassessed.
