A London entertainment writer tries out a human-powered dance floor at the city’s new eco-friendly disco, Surya.

From the article:

…The star of the show – the dance floor – is downstairs. It’s the most innovative part of the club and harnesses the motion of dancers to generate power. It uses the concept of piezoelectricity, where materials rub together to generate a charge – in this case, crystals in blocks under the floor which create an electrical charge when squashed – which is then fed into batteries. It’s normally used in cigarette lighters, but Surya is the first venue of its kind to use the electricity generated to power light as well as the air purifier and ioniser.
