Energy Management System Cuts Hybrid Fuel Consumption by One-Third

Xuewei Qi and a team of UCR researchers are using vehicle connectivity and evolutionary algorithms to improve the efficiency of plug-in hybrid electric vehicles.

Engineers at the University of California, Riverside have taken inspiration from biological evolution and the energy savings garnered by birds flying in formation to improve the efficiency of plug-in hybrid electric vehicles (PHEVs) by more than 30 percent.

Riding the Energy Sector Rollercoaster

Managing any business directly or indirectly affiliated with the oil and gas sector today is a challenge. You can compare the last five years in the energy industry to riding a speeding rollercoaster. One second the industry is climbing, and the next, it is plummeting. So perhaps you should ask yourself, “Is my company ready for the ride?”. This paper will help you answer that question and more.

Editor's Choice: January 2017

The Convective Heating Improvement for Emergency Fire Shelters (CHIEFS) material can improve the performance of emergency fire shelters for wildland firefighters. The material is based on technology developed for planetary exploration mission heat shields. Fire shelters are the last resort for firefighters trapped by wildfires that block their escape routes. The CHIEFS system can withstand temperatures to 3000 °F. Click here to find out more.

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.

Thermal Optimization for Energy Efficiency

Nearly everything has an optimal operating temperature and thermal condition. Millions of dollars each year are spent generating and transporting thermal energy to achieve thermal goals. Thermal optimization not only improves the economy of transporting energy, maintaining building temperatures, manufacturing processes and products, it improves their efficiency as well. Engineers use simulation to reveal detailed pictures of thermal processes, providing a deep understanding of all aspects of thermal management.

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.
