Thermal Metamaterial for Waste-Heat Harvesting in Power Plants and Factories

The thermal metamaterial was developed in research aimed at efficiently harvesting waste heat from power plants and factories. (Purdue University/Sean Molesky) An international research team has used a thermal metamaterial to control the emission of radiation at high temperatures, an advance that could bring devices able to efficiently harvest waste heat from power plants and factories. Thermophotovoltaic devices that generate electricity from thermal radiation might be adapted to industrial pipes in factories and power plants, as well as on car engines and automotive exhaust systems, to recapture much of the wasted energy.

Technology Powers Implants Wirelessly Via Ultrasound

The basic structure of the ultrasound power supply and communication. (© Photo Fraunhofer IBMT) Scientists have developed a demonstrator that powers active implants wirelessly via ultrasound. Ultrasound waves have a broader range in the body, and they penetrate the implant’s metal casing more easily than electromagnetic waves. The ultrasound waves are also capable of bidirectional transfer of information, such as the temperature of the implant, or details regarding the type and intensity of electrical stimulation.

Renewable Energy Could Be Under Our Feet

Associate Professor Xudong Wang holds a prototype of the researchers’ energy harvesting technology, which uses wood pulp and harnesses nanofibers. (Photo: Stephanie Precourt) Flooring can be made from any number of sustainable materials, making it, generally, an eco-friendly feature in homes and businesses. Now, flooring could be even more “green,” thanks to an inexpensive, simple method developed by University of Wisconsin–Madison materials engineers that allows them to convert footsteps into usable electricity.

2016 Create the Future Design Contest: Grand Prize Winner

HYLIION - HYBRID TECHNOLOGY FOR SEMI-TRAILERS AND THE TRUCKING INDUSTRYThomas Healy, RF Culbertson, AJ Emanuele, Morgan Culbertson, Wilson Sa, Pam Culbertson, Chad Saylor, Len Kulbacki, Eric Weber, Adam Faris, Kim Kasee, Roger Richter, Jared King, Phil Aufdencamp, and Tim GehringHyliion, Pittsburgh, PA "The Hyliion team is honored to be the Grand Prize winner of the prestigious Create the Future Contest. It is a tremendous validation of the impact the Hyliion Intelligent Electric Drive Axle System will have on the trucking industry, and the environment." Hyliion is bringing hybrid efficiency to the trucking industry by replacing a semi-trailer’s passive axle with the Intelligent Electric Drive Axle System. The system can decrease fuel consumption and reduce emissions by capturing wasted energy and storing it in a battery pack to help propel the trailer when needed. Currently, tractor-trailers get 6.5 miles per gallon, and on average use $48,000 of fuel annually (per tractor). The trucking industry in the U.S. spends $150B per year on fuel; 6.2% of all emissions in the U.S. comes from trucks.

2016 Create the Future Design Contest: Sustainable Technologies Category Winner

DESOLENATOR — WATER FROM SUNSHINE “Desolenator is extremely proud and thankful to all those who voted for us. We believe that the global water crisis is a serious issue, and winning recognition from a leading publication offers great support to our efforts. We will surely return to share our progress with readers over the coming years.” William Janssen, Desolenator, London, UKThe Desolenator is a water-purification technology that decontaminates water from any source using only solar energy. The technology is a very affordable ($0.005/L) “at-source” method of water purification. It offers a combination of features and capabilities that makes it extremely well suited for household use. It is GSM-mobile enabled and is data-driven through sensors, enabling service through micro mobile payment. It is eco-friendly, has a lifespan of up to 20 years, doesn’t require filters/ membranes, doesn’t drain the main’s electricity, and doesn’t expel toxic waste into the ocean. The long-term goal is to prevent the worsening of the water crisis.
