The water that you unleash when you take a shower (with the "hot" knob closed) has two properties: pressure and temperature. You can change pressure, but to raise its temperature you usually need extra energy. Regularly, you don't shower with the water knob turned to the maximum, so a certain extra pressure exists in the tubing, creating friction.
The world we live is full of f vibrating surfaces like train stations, dance floors and highways that that could yield a rich trove of clean, eco-friendly energy. It is called piezoelectric energy, formed by the conversion of mechanical strain into electricity.
University of Michigan researchers, at their Engineering Research Center for Wireless Integrated Microsystems, have just created highly efficient some energy-harvesting devices that use the energy from surrounding arbitrary, non-periodic vibrations.
Researchers from the University of Notre Dame in the US have designed a PZT (lead zirconate titanate) piezoelectric device that resembles skin (they called it the EH skin) and that can harness energy from the mechanical work applied to it. The new device can be used in a variety of applications, ranging from wireless sensor units to patches that get energy from vibrations and pass it on to the grid. The sample they tested got as much as 3.7 mW.
Yesterday morning, the Hefer intersection along the old coastal road of Route 4 in Israel was the place where a piezoelectric generator was put to the test and generated some 2,000 watt-hours of electricity. The setup consists of a ten-meter strip of asphalt, with generators lying underneath, and batteries in the road's proximity.
When cars or trains move on the surface of the earth, they produce vibrations. These vibrations can be captured and directed through underground piezoelectric materials to a smart grid or roadside batteries.
City College of New York researchers, led by professor Yiannis Andreopoulos, are studying how to incorporate piezoelectric electricity generators into cars and planes, so they can convert the kinetic energy of motion into electricity.
Engineers at Stony Brook University in New York have won a national award for developing an energy harvestor that significantly reduces railroads’ carbon dioxide...
