Free piston/ORC system for automotive waste heat recovery being tested at University of Brighton

Green Car Congress

A prototype automotive waste heat recovery system has been fired up on a recently commissioned test rig at the University of Brighton. Initially configured to simulate heavy duty truck applications, the 20 kW e system can be scaled down to 3 kW e for light duty trucks and passenger cars. 2014.05.041. Champagne, L. 2013.08.045.

BMW Study on Rankine Cycle for Waste Heat Recovery Shows Potential Additional 10% Power Output at Highway Speeds

Green Car Congress

In this study, BMW focused on Rankine A (exhaust gas only) and Rankine B (exhaust gas and coolant). BMW is exploring two pathways for waste heat recovery in vehicles: one thermoelectric, the other thermodynamic. System A used exhaust gas only as the heat source; System B used exhaust gas and coolant.

Cheap Sensors for Smarter Farmers

Cars That Think

One of the benefits of using print electronics is being able to mass-produce at a low cost, says Gregory Whiting at the University of Colorado, Boulder, one of the principal investigators of the team working on the sensors. One problem with mass-producing sensors, however, is that it creates a lot of waste.
