ETCs made from coke glass, which has a green tint, are stronger and less likely to lose their vacuum, but efficiency is slightly reduced due to reduced transparency.

Although coke and scrap prices appear to have peaked in 2005, prospects for coal and iron ore are less certain.

Wootz steel which is also known as Damascus steel was a unique and highly prized steel developed on the Indian subcontinent as early as the 5th century BC.

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

In these circumstances, to develop new coal projects is unethical, and to invest in them is to be complicit in this unethical activity. While this applies, to some extent, to all fossil fuels, the best way to begin to change our behavior is by reducing coal consumption.
