System Harvests Energy from Automotive Shock Absorbers

Boosting the fuel efficiency of motor vehicles by “harvesting” the energy generated by their shock absorbers and feeding it back into batteries or electrical systems such as air conditioning has become a major goal in automotive engineering. A University of Huddersfield (UK) researcher has designed a new system and built a prototype that is ready for real-world testing.

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

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

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

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.

New Material Increases Lifetime of Solar-Powered Electrons

Nobody wants a laptop computer that stops working when a cloud passes by. Storing sunlight as fuel that can be later used to drive fuel cells requires new materials. Scientists demonstrated just such a material by combining two oxides on the atomic scale.

A New Generation of Cooling

Energy efficiency is key to the total cost of ownership of enclosure climate control solutions, and electricity consumption is a major element of operating costs. Hybrid technology, developed and patented by Rittal, combines conventional compression cooling, similar to what has been used in traditional air conditioners, with a heat pipe. The heat pipe uses evaporation of a working fluid in an evacuated tube.
