Comments Off on 13-year-old Ohio girl taps traffic to generate renewable energy

We may be one step closer to tackling our energy crisis if this 8th grader has anything to say about it. 13-year-old Laalitya Acharya from Ohio came up with TraffEnerate, an invention that uses vehicular traffic to generate clean power . She’s a finalist in the 2017 Young Scientist Challenge , and stands to win $25,000. Acharya started researching cheap, easily renewable resources of energy, and came across a device she calls a piezo. She explains when stress is applied to a piezo, it generates electricity . She wanted to make it easy to utilize piezos, so she designed TraffEnerate to obtain power when cars drive over the devices. Her prototype incorporates 11 piezo sensors and a 3D-printed block so stress will be applied to all 11 piezos even if a car just barely passes over the corner of the prototype. Related: 13-year-old Maanasa Mendu invents groundbreaking clean energy device that costs just $5 Acharya also designed a reciprocating motion machine to test the prototype. Her robot consistently applied stress to the invention, seen in an oscilloscope reading. She hopes to implement TraffEnerate in the busiest intersections of her hometown of Mason, Ohio . Acharya said on the challenge website, “I wanted to change the world, that simple. On my family’s yearly trip to India, I saw children who have no power in their homes, huddling near dangerous fires. I wanted to change their position in life, to make it better by creating clean energy and electricity.” The 2017 Young Scientist Challenge is put on by Discovery Education and 3M . There are 10 finalists for this year’s challenge, with innovative projects such as a way to detect lead in water, treating Alzheimer’s with plant components, and cleaning up oil spills with pomegranate husks and orange peels. A winner will be chosen in October. + Young Scientist Lab Via Young Scientist Challenge and Rajesh Acharya Images via screenshot

Comments Off on MIT Develops Polymer Film That Harvests Energy From Water Vapor

Researchers at MIT just developed a new bio-polymer film that is able to generate electricity from a readily available source: water vapor. The material changes its shape as it absorbs evaporated water. As the bio-polymer film repeatedly curls and unfurls it drives robotic limbs, which in turn generate enough electricity to power micro- and nanoelectronic devices.

Comments Off on Solar-Powered Lightning Motorcycle Sets New Speed Record for Production Motorcycles at 189 MPH

Last year, Lightning Motorcycles shattered the land speed record for electric bikes, when rider Paul Thede achieved an amazing average of 206.079 miles per hour at the Bonneville Salt Flats. The team later set a higher speed of  215.960 mph. Now, Lightning Motorcycles has broken the speed record for a production motorcycle (a street-legal bike that was produced in a series for purchase by the public) with a solar-powered bike at the El Mirage dry lake bed  in Southern California.

Georgia Tech’s Self-Charging Piezoelectric Power Cell Can Harvest 5X More Energy From Footsteps

Comments Off on Georgia Tech’s Self-Charging Piezoelectric Power Cell Can Harvest 5X More Energy From Footsteps

A team of researchers from the Georgia Institute of Technology have developed a self-charging power cell that is able to directly convert mechanical energy into chemical energy. The cell then stores the power until it is released as electrical current. The all-in-one piezoelectric power cell essentially eliminates the need to convert mechanical energy to electrical energy for charging a battery, as its new hybrid generator/storage capability utilizes mechanical energy more efficiently than systems which use separate generators and batteries.

Comments Off on Humdinger Wind Energy develops portable wind energy harvester

Eco Factor: Portable wind energy generator to power wireless sensors. According to statistics, about 2 percent of global electricity comes from wind-powered generators, and their capacity has doubled in the past three years. However, scaling down wind turbines for use as an electronic device charger hasn’t proved fruitful, as conventional wind turbines require rotating fins and gears, which add bulk, making the device inefficient when scaled down.
