Picking Up Good Vibrations – Tiny Energy Harvester is Most Powerful Yet

Recently, electrical engineers at the University of Michigan, have perfected a device that can harness ambient, mechanical vibrations and convert these into electricity at 5 to 10 times the efficiency and power output than previous devices of this type. At 27 cubic millimeters, a single such system fits — with room to spare — on a penny. According to the engineers, the wireless/battery-less devices can be installed and left alone for 10 to 20 years, essentially a “limitless shelf time”.

Eco-Artist Creates 'Puff' Device to Monitor Car Emissions

Puff (a car exhaust monitoring device) is attached near the exhaust pipe of your vehicle. Its color changes dynamically, visualizing the amount of pollution your car is producing. Green indicates the lowest rate of pollution, red the highest. Karolina Sobecka, the artist/designer of Puff, explains: In this project, design is used as a strategy to explore the overlap between the material and immaterial worlds and spur discussion on the hidden social and psychological mechanisms behind the cultural use of accessories as ‘objects to think with’…Amateur Human (the design project’s official name) focuses on the environmental issues since we all are inadvertently becoming more eco-conscious whether we want to or not, and these issues seem both overwhelming and ambiguous.
