Wartime Bunkers: The Perfect Place for Research and Innovation

摘要

One of Europe's newest solar- and biofuel-power stations is a former Hamburg air-raid shelter called the Energiebunker. The 138-foot-tall structure was inaugurated last year and is scheduled for completion in 2015. It holds equipment that will generate electricity for 1,000 households and heat for 3,000, creating 95 percent less carbon-dioxide emissions from heating than oil and gas boilers.
