Electrified cement could turn houses and roads into nearly …
Tesla''s Powerwall, a boxy, wall-mounted, lithium-ion battery, can power your home for half a day or so. ... Although these perform well, the ingredients are expensive and hard to produce in the massive volumes used in the cement industry, notes Franz-Josef Ulm, a civil engineer at the Massachusetts Institute of Technology (MIT).
internal consistency
Normally making iron from just charcoal and a high quality iron ore requires about 50-60 parts charcoal and 2 parts iron ore (by weight) to get 1 part refined steel. So, technically you can make steel using just charcoal, but you would run out of trees very fast trying to mass produce steel this way.
