Researchers Advance Printable Solar Cell Possibilities

By finding a new way to manufacture low-cost perovskite solar cells, a team at the University of Toronto believes that making solar cells could someday be as easy and inexpensive as printing a newspaper. The researchers' alternative solar technology supports the development of low-cost, printable solar panels capable of turning nearly any surface into a power generator.

Long-Lasting Flow Battery Advances Renewable Energy Efforts

A new flow battery from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) stores energy in organic molecules dissolved in neutral pH water. Losing only one percent of its capacity per 1000 cycles, the non-toxic, non-corrosive device offers the potential to significantly decrease the costs of production.

Iowa State University scientists have built a device that mimics the branches and leaves of a cottonwood tree and generates electricity when its artificial leaves sway in the wind. The device is derived from biomimetics, or the use of artificial means to mimic natural processes. Such biomimetic technology could become a market for those who want to generate limited amounts of wind energy without the need for tall and obstructive towers or turbines.

System Harvests Energy from Automotive Shock Absorbers

The energy harvesting device focuses on the car’s suspension – specifically, the 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.

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.

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.

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.
