Wind, as we all know, can be used to generate electricity. Turbines installed in wind-prone areas have been proven generators of clean, green power. But most of the time, you need open areas and large spaces to locate these. So how do you bring wind power to the city? Mark Oberholzer may have just the solution, designing a system that would generate power from a rather unique place: The New Jersey highway. And he doesn’t propose that we install wind turbines near the highway, but rather, that they be put in the highway, and that they power a light-rail transport system.
The design, a runner-up in the 2006 Metropolis Mag Next Generation Design Competition proposed the integration of wind-turbines into the highway barriers that divide the traffic. These turbines would generate power from the wind created by the vehicles that drive past them in opposite directions. Originally conceived as a single row of vertical-axis rotary turbines, it has now been redesigned to include two rows, one stacked on top of each other, with the end power being used to power a light rail system.
“The peaks of traffic flow more or less coincide with those of energy use,” Mark says. As the traffic peak hour matches requires the moving of a large amount of people, integrating it with a traffic rail system may have a second beneficial effect: that of decongesting the busy highways.
As more and more people across the world adopt cars as their primary mode of transportation, well-lit highways become increasingly important. But how can we sustainably power all those energy-sucking lights? TAK Studio addressed that question in their entry into this year’s Greener Gadgets competition to find the green technology solution of the future. Dubbed the Turbine Light, their design aims to illuminate roadways using the power of the wind.
TAK’s wind-powered light uses the moving air from cars zipping by on the highway to generate energy that can be used to power roadside lighting. It’s a controversial idea–could wind from passing cars actually provide enough power for lighting?–but one that has the potential to save lots of cash in already wind-heavy regions. Alternatively, cities might consider using solar-powered lights instead. The idea has been proven to work many times over, including at the recent COP15 climate change conference.
