Revolving Doors Harvest Human Energy

Energy harvesting revolving doors capture otherwise wasted human energy and convert it to electricity to power the installation site, for example lighting and signage.

Designers Jennifer Broutin and Carmen Trudell at design studio Fluxxlab have created Revolution Door, which is a modified revolving door made up of three parts - a redesigned central core replacing that of any existing or new revolving door, a mechanical/electrical system that harnesses human energy and redistributes electricity to an output, and an output device that maps the harnessed energy. The energy harvesting revolving door was exhibited in Manhattan's Eyebeam art and technology centre. When visitors walked through the door, the energy harnessed was used to power a sign that lights up as people pass through.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
