High-Performance Silicon Carbide-based Plug-In Hybrid Electric Vehicle Battery Charger (http://www.youtube.com/watch?v=W-rRm9Sb0NY#ws)

That's the 3 kW production charger in his right hand from the Toyota Prius PHEV.
His left hand is holding a prototype 6 kW silicon carbide charger. Produces significantly less heat (95% efficient), weighs much less (3.8 kW/kg), is much smaller (5 kW/L).
InsideEVs has an (atypically) shitty article (http://insideevs.com/heres-slash-cost-tesla-model-s-6000/) talking about how the efficiency will drive down costs in a Model S. I cast a lot of doubt on that, but smaller power electronics = winning for electric bikes..... I want this in a bike now!
The heart of the charger is APEI's 1 MHz+ high-frequency capable multi-chip power module allowing for 200 °C+ high junction temperature operation which, when coupled with high switching frequency, allows for an order of magnitude increase in power density -- with a simultaneous increase in system efficiency over currently used technologies.

Where do I place my order...! :)
