I was blown away by the invention of the play pump – a childrens round about which uses their energy to pump water – a couple of years ago and the core idea is gathering pace. The most recent application is harnessing human power using revolving doors.. at last they have a purpose. Fluxxlab studio is developing this [via inhabitat]:
I’m not having much progress coming up with a decent name for this. The best I’ve got is jinriki which is japanesse for ‘human powered’ (that’s where the name rikshaw came from) I’ve you’ve got anything better let me know!
