• Resumen

  • Ravilious narrates how urban centers conceal a lost fortune. An environmental engineer at Linkoping University in Sweden, Mats Eklund is one of a new breed of prospectors who prefer to head downtown rather than out into the wild. Their target is "urban ore"--forgotten supplies of metals that lie in and under the city streets. Eklund has spent several years tracing abandoned cabling and long-lost pipework beneath roads and pavements. His fieldwork suggests that many cities contain precious seams of valuable metals locked up in discarded subterranean infrastructure.
