It may not sound like much, but take the 30,000 or more people who pass through a major-city subway hub at rush hour, and suddenly you’ve got serious power. That’s usually a problem for architects and engineers, who have to design structures to withstand such small but persistent pressure. But the Facility, a London architecture firm, sees it as an opportunity. The company proposes putting small hydraulic generators in floors to capture vibration and convert it into electricity.
