A guillotine, if one designed to crush rather than cut. The weight of the crusher will need to be pretty significant, so the motive force to elevate it is a geared ratchet (cool sound) powered by pedaling a bicycle. One at the drop point, a can (or collection) is placed underneath to be flattened. Once so squished, a trapdoor can be activated to drop them into the receptacle below.

The “Conscious Shower” is an alternative to reduce the amount of water spent in the shower in a fun way. To do that, a water meter has to be installed in the shower. It’s necessary to set up an amount of water enough for a shower (eg. 40 liters). So it will be possible to check in a screen how much water is being spent during the shower.
This is my idea to use positive reinforcement to encourage people to buy tickets when they travel on public transport. The idea is that through buying a tram ticket and having it stamped onboard, you get the chance to enter an instant win lottery. A pretty fun way to reward people for buying a ticket.

This project aims to create energy and entertain people while waiting at the bus stop.The goal is to use all energy created by man power, through jumping on a board on top of a spring.This will in turn create enough energy to power a lightbulb on the spot they are jumping on, at another nearby spot, or by creating them as part of a game (chess, dancing, etc).
It can also be extrapolated to other waiting areas according to their environment.
The use of the bicycle as a daily transport system is not a new idea. Everybody knows the health and environmental benefits of riding a bicycle. But several constrains, such as weather uncertainty, urban street morphology, traffic hazards, and even laziness, all have a significant impact in the – limited – use of the bicycle in urban areas.
