Researchers at the University of Manchester (UK) have developed a graphene-based nano-rectifier (“ballistic rectifier”) that can convert waste heat to electricity. Graphene was the world’s first two-dimensional material, isolated in 2004 at The University of Manchester; since then a whole family of other 2D materials have been discovered.

The new cycle combines both Diesel and Ericsson Cycles into an integrated process to recover waste heat within a single thermodynamic cycle. Key changes to implement the integrated cycle are isothermal compression and heat addition from the exhaust gas to the charge air after the end of compression. Based on a modified MTU Series 396.

Among the projects discussed were reducing cold starts; using waste heat for different heating applications in the car; and a new implementation of a thermoelectric generator (TEG) for waste heat recovery.

An Atmospheric River originating over the central Pacific on 16 February 2004. These impacts, the authors noted, are not exhaustive. Much has been done to protect the state from future flooding, but the state flood-protection system is not perfect. Source: USGS. Click to enlarge. An ARkStorm would be a statewide disaster.

Audi presented a range of its ongoing work on electromobility and efficiency—from fuels and systems to full vehicles—under the “Future Performance Days 2015” banner. This makes it possible for the waste heat from the electrical drive components to be made available to the interior of the Q7 e-tron quattro.
