No, the technology for busses is a great idea. It will save a lot of fuel and reduce emissions. And whatever is learned will transfer. Hybrid busses are an even better idea than hybrid cars.

What a great concept-- a hybrid diesel-electric that'll haul passengers.

We should call it... a locomotive.

Nords, you kill me..........

Too bad our roads don't have the low coefficient of drag/rolling resistance than railroad rails do........no wonder those guys can pull a locomotive with their teeth, try that with my minivan!!!

I'm not an engineer, but I wonder how MUCH diesel we would save by getting the MPG UP on semis........I guess they got around 4mpg in the 70's, and now get around 7-8mpg. There has to be a way for a regenerative system so they can capture some energy to use at the lower rpm's.........I thought electric motors had HUGE torque right away? So why can't we figure it out??

BTW, my comment above was sarcasm, not intended to be an actual statement of interest.

FD...I'm fully prepared to attempt to pull a train with your minivan.

Shoot...looks like I owe Justin another 50c. I better see if I can line up any more work with Mike.

There are other regen systems than electric. Some vehicles that make frequent stops store stopping energy with a hydraulic pressure storage system which is released to launch the vehicle back up to speed. Perfect for buses, garbage trucks, UPS, etc. Less expensive than batteries and low tech.

Dude...this has a deja'vu ring to it. Travelover is right, re-read your thread on this from a while back:


Real Way to Save Oil..............



Hybrids good for stop/go. Electro-motive good for locomotive (they would need 200 gear changes to get that dead start load moving). Hybrid on a long-haul semi? If it was so good they would be doing it already. The transportation companies are well aware that fuel costs money and that more mpg means less fuel.

And while low sulfur diesel fuel can be a great thing for the environment, it isn't helping any in diesel mpg:

Ultra-low sulfur diesel - Wikipedia, the free encyclopedia

The refining process that removes the sulfur also reduces the aromatic content and density of the fuel, resulting in a minor decrease in the energy content, by about 1%. This decrease in energy content may result in reduced peak power and fuel economy.

Seems like a good trade-off though.

What I MEANT was that the rolling resistance on a locomotive is SO MUCH LESS than a minivan that the same "strongman" that can pull a loco with his teeth would be wearing dentrures soon after trying to do the same with my minivan..........

Yeah I know. But it'd be more fun to do it with your minivan.

I used to have a 67 Chevelle 396 H.O.I probably WOULD have tried to do that with.......

I heard Honda Pilots can tow 100,000 tons these days...........

Honda Fit: We looked at this last time we were car shopping, 5 years ago. Impressive mileage, but scary as heck from a safety standpoint.

Good word play!

What's good for the country is good for General Motors. And it was in this case too - EMD (Electro Motive Division), a division of General Motors. The biggest maker of diesel-electrics the world over.

Isn't the car called the Honda FIT here in the US, a new design? The older Honda citycars in Japan would never meet US safety standards. I was under the impression that the Honda FIT was designed for the North American market.

Externally, it looks like the same car they've been selling here for six years. Wikipedia sez:

Quote:
In keeping with Honda's safety initiative, the Fit is offered in North America with standard side airbags, side-curtain airbags, and ABS, in addition to the mandatory front airbags. Due to differing safety regulations, North American Fits have larger bumpers than the rest of the world, resulting in a slight increase in overall length.
The Fit is offered in two variants in the United States (Base and Sport), and three in Canada (DX, LX and Sport). Differences are primarily limited to cosmetics and standard equipment. All models share the same 1.5 L 109 hp (81 kW) engine and standard 5-speed manual transmission. A conventional 5-speed automatic transmission is optional, instead of the CVT found throughout the rest of the world. The Fit Sport receives paddle shifters mounted behind the steering wheel when ordered with the automatic. In the United States, the base model is priced at US$13,850, with the automatic transmission adding $800 and the Sport package adding $1,320. In Canada, it starts at CAD$14,980 for a DX with manual transmission, and goes to $20,880 for a Sport with automatic transmission.
Doesn't sound like the differences are very significant.

I can certify that they'll tow about 30,000lbs, about 1000lbs at a time...

On our local NPR station - the railroads are adverting about how efficient they are - can pull a ton of cargo 400 miles on a gallon...those rails must be real slick

The fuel ships and locomotives burn is some nasty stuff. Ever see the black cloud coming out the smokestack? - sort of like burning tires.......

I worked on a barge on the Mississippi River for a summer. I burned my clothes after the job was over, and they burned warm and toasty.........I guess the diesel soot overran the flame retardant coating.........

Sure, Company used to work for ran steamships - burned No. 6 fuel oil (residual- left over after refining gasoline, etc)..gradually dropped steam - replaced with diesel. Think EPA is proposing new standards this year that will greatly reduce emissions for locomotives. Ocean Shipping also being pressured to reduce use in port - retrofitting for electric power while in LA Harbor for example.

Same here!
