Shoppers - the new eco-energy supply?

I have been reading in The Sunday Times (UK) this morning that "the footfall of trudging shoppers is to become the latest source of emission-free energy".

Using under-floor generators, the technology could use the footsteps of pedestrians to power thousands of light bulbs at shopping centres. It uses the pressure of feet on the floor to compress pads underneath, driving fluid through mini-turbines that then generate electricity, which is stored in a battery.

The Sunday Times reports that engineers have carried out a trial of this technology at Victoria Underground station in central London, and have calculated that 34,000 travellers passing through every hour could power 6,500 light bulbs.

The article goes on to explain that the same principle can be applied to harnessing energy from trains moving over railway lines. But the most relevant application of this technology for this blog is the possible application in new office buildings.

Here is a link to the
original article.
