Did you know that every time you take a step, you generate six to eight watts of energy? But then — poof! — it dissipates into the air.

If only you could capture it.

An architectural firm in London is now looking at ways to capture that energy on a large scale and turn it into electricity. For example, 34,000 people walk or dash through Victoria Station in one hour, rushing toward their trains. That’s a lot of steps. “If you harness that energy,” says the firm’s director, “you can actually generate a very useful power source.”

According to Fast Company (September 2006), this architectural firm is working to develop vibration-harvesting sensors. These sensors would be implanted in the structure of train stations, bridges, factories or any other building frequently rattled by commuters,
