Propeller Helmet (2009)
Two propellers mounted to a helmet harness the airflow for electricity production. Electricity is then stored in two built in batteries. Additional LED-lights provide direct light-feedback when propellers are rotating in order to visualise the relation between wind intensity and electricity and allow the unseen wind power to be perceived through light.
The helmet’s usage is not only limited to cycling but serves the purpose also while snow boarding, skiing, sailing or hiking. The electricity stored in the helmet can be used to charge batteries of your mobile devices (mobile phones, ipods etc) via two USB interfaces. It requires about 2hrs of cycling at middle (wind) speed to fully charge the integrated batteries power your gadgets completely off-grid.
It wasn’t my intention to build another “green gadget” but instead utilising the prototype to showcase that environmental topics can be integrated into the lifestye of young people. Since public discourse about the environment had a very negative and moral tendency that time in Switzerland I also aimed to design a positive experience, coupling fun with environmental awareness.
