A Zeppelin comeback
With rising fuel prices dominating the news and affecting every level of the global economy, some solutions to fuel-efficient transport aren’t necessarily hi-tech ones. Many draw on older technology that until now was nearly obsolete. Germany has recently been producing airships again, which could soon be ferrying people around Europe and even to farther-off destinations. The slow-moving zeppelins are still as fast as high-speed trains, and in addition to low fuel consumption and low flight altitudes, very little new infrastructure has to be built to accommodate them. Let’s just hope they don’t still fill them with hydrogen.
