Looking Out From the Garage: April 2011

53 Cool Concept Cars... Part L...

I have been busy over on my other blog, plugging away writing 6 posts a week... And I have been working on this series for about a year. There are only 3 more to go (L = Roman Numeral 50).  Come on over and see what I'm up to over there...

I previously wrote about a diesel-electric RV... and the natural extension from that would be a diesel-electric semi.  After all, it is the power supply of trains.

Yep... diesel powered trains are actually hybrids, and they always have been.  The diesel engine powers a generator producing electricity.  At the axles, there are electric motors that provide the actual motive power.  The advantage is that the diesel engine can be tuned to run under a more specific RPM range... basically tuned for maximum efficiency.  Instead of the engine speeding up and slowing down with the speed of the truck, it only needs to react to the needs of the generator.

In the case of a semi, they already weigh a lot.  So, the addition of some battery packs wouldn't have as much of an impact.  And since the size (and weight) of the engine could be reduced, the generator package shouldn't add that much weight either.

It sure would be an interesting hybrid.  And since tractor-trailers spend all of their time on the road, often running well over a million miles, they should be able to actually pay back the increased cost of the hybrid system.  (Just guessing about that...)

It would be pretty cool, though.
