Vettel in the twilight zone

Sebastian Vettel gave Red Bull Racing a hat-trick of wins to finish off the 2009 season with a dominant victory in the inaugural Abu Dhabi Grand Prix. Although Lewis Hamilton qualified well and led from the start, it was clear early on that the McLaren driver was not able to pull away from Vettel and at the pit stops was overtaken by Vettel just before he went out with a rear brake problem. After that Vettel was untouchable. It was not a great race, overtaking clearly being very hard, but there was some excitement in the last laps as Webber struggled to hold off a charging Jenson Button.

Vettel's brilliant win cemented second place for him in the Drivers' World Championship behind Button and ahead of Rubens Barrichello, who was never able to challenge and had to make do with fourth place.

would pouring water in a BMW coolant rather than antifreeze cause to over heat?

My BMW is over heating, but I have to pour water instead of antifreeze. I live in Florida im, so pouring antifreeze instead of water make a...


In an emerging water is fine but has antifreeze corrosion inhibitors in it to prevent corrosion. With a lot of aluminum parts, makes the water efflorescence and not good for the engine for a long...

GM awarded DOE money to research Shape Memory Alloy heat engines ...

General Motors has been awarded $2.7 million by the Department of Energy to create a working prototype engine using Shape Memory Alloys (SMA). The idea is for the prototype to use SMA tech to capture heat energy from engine exhaust gasses via an electric generator and transfer that energy to recharge batteries for hybrids or electric vehicles. SMA tech can also theoretically power electronic devices like power seats and windows in a standard gas- or diesel-powered car, perhaps even replacing the power-sapping alternator. The GM press release, which is pasted after the jump, doesn't go into much depth explaining how memory alloys work, but the basic principle is easy to understand. While $2.7 million isn't a lot of coin in the realm of GM finances (the General seemed to shed about $2.7 million every ten minutes pre-bankruptcy) the grant was significant in that it was the only monies awarded by the DoE given to an automaker. GM is working with partners from outside the auto industry to make the concept a reality, a practice that the General says is imperative to get breakthroughs like this to market. No timetable was given as to when GM's SMA concept would see the light of day. The award from the Department of Energy's Advanced Research Program Agency – Energy, or ARPA-E, was the only grant to an automaker among $151 million in distributed by the DOE. GM will work with HRL Laboratories; Dynalloy, Inc., a Tustin, CA manufacturer of shape memory alloys specially made to be used as actuators, and the Smart Materials Collaborative Research Lab at the University of Michigan.

I think BMW was working on something similar, but it used waste exhaust heat to create steam that add power directly to the drive shaft. I imagine it could be used to generate for electricity for a hybrid too. Here's the original Autoblog article with more detail.
