Pavegen, an initiative that makes tiles which are fitted with technology that converts the kinetic energy of footsteps to electricity, was seen as a “particularly intelligent” effort by the NT100 steering committee.The energy harvested by the tiles can power nearby pedestrian lighting or advertising signage, or also be stored in a battery.The tiles also made an appearance in Singapore during Earth Hour 2013, where they were used to tile a dance floor. As event-goers danced, the kinetic energy of their footsteps was used to power an on-site screening of a film about the campaign.
