Local jurisdictions in Red state America, increasingly unable to agree to taxes to jointly afford repaving at peak oil prices are simply letting roads decline – in the same way as after the fall of the Roman Empire, in the dark ages there, many roads in Europe returned to mud tracks.
But an innovative new oil-free way of surfacing roads could be on the way to save us from peak oil. This “sandstone” road surface is built by bacteria just using sand, so it’s cheaper. The idea from Thomas Kosbau + Andrew Wetzler is the winning entry in the Korean green design iida awards, announced by designboom.
