HUFFPOST | Buildings of the future will be grown on-site, says Wil Srubar. They’ll be made from hemp, or algae or specially engineered wood — or bacteria that can photosynthesize, like the cyanobacteria mortar he and his research team recently grew between a lattice of sand and water-based gel.
“In my future world, we don’t burn limestone to make cement, and we don’t melt sand to make glass,” he says. Instead, essential building materials might be grown from bacteria that glow (bioluminescence) or from engineered lichen, so that walls are infused with the organism’s remarkable properties. Imagine a house that could filter carbon dioxide from the air or change color if harmful gases are present.
