Graphyte, a new company incubated by Bill Gates’s investment group Breakthrough Energy Ventures, announced Monday that it has created a method for turning bits of wood chips and rice hulls into low-cost, dehydrated chunks of plant matter. Those blocks of carbon-laden plant matter — which look a bit like shoe-box sized Lego blocks — can then be buried deep underground for hundreds of years.
Sure. But turning it into building material would be even more amazing?
Be nice, but we’re talking about remote locations with a high cost of transport. It’s unlikely to be cost-effective
Even when it is bury for no value vs sell to replace carbon-producing materials? I don’t buy it. Very few places are so remote that there is zero local-ish demand for building materials and they have to build facilities and support workers in those remote places instead.
