Slideshow: Automakers Look to a Hydrogen Car Future
5/8/2013

Introduced in 2009, the Mercedes-Benz F-Cell Roadster concept car mimics the Benz Patent Motor Car from 1886. Fitted with spoked wheels, carbon fiber bucket seats, and a hydrogen fuel cell drive, the car was the product of 150 students and Daimler AG trainees tasked with designing an alternative fuel vehicle. The F-Cell Roadster is controlled by drive-by-wire technology and employs a joystick instead of a conventional steering wheel.(Source: Mercedes-Benz)

I believe the joy stick would be the 2013 equivalent of a tiller.

The speed and range specifications and refueling times for Hydrogen Fuel Cells certainly seem more practical than the all electric vehicles.  The explosion risk is always there with hydrogen.  I think development of a large scale hydrogen infrastructure would be the hardest thing to overcome.  It is very hard to store.

equivalence between mpg and mpkg

The caption of slide 6 states one mile per kg of gasoline is considered equivalent to 1 mpg.  Since a gallon of gasoline is approximately 13.3 kg, this does not seem to make sense.  Is this a misprint or am I missing something?

What about the "BOOM" factor of carrying around a substance that is know to blow up space shuttles? Drivers do not seem to be getting any better at driving, even with the advancments in safety technology!

Bloom Energy corporation has been producing fuel cells using methane a.k.a. natural gas or CH4 for fixed installation as commercial building power sources for a few years now. Lesley Stahl did a piece on 60 Minutes about them. A link to their website appears below:

It shouldn't be a problem to scale the technology down for either home or mobile use.

While it doesn't completely eliminate carbon from the fuel cycle, the higher efficiency of fuel cells versus internal combustion engines drastically reduces the carbon footprint and my understanding is that the cell chemisty used can be adapted to hydrogen fuel without too much trouble.

Yes stylish for a student that is probably used to driving their bike around campus and then has the brilliance to put his bike tires on a "car"(?). Innovation, sure. Practical, NOT.

I think this was mentioned, but what is the energy input to make hydrogen fuel compared to the energy output to motor a vehicle?

There was a lot research being done on Fuel cells using natural has there been any progress made? With all the sources of NG this could be used right away! PS what happens to the small amount of carbon when NG or propane is run through a fuel cell?

A joystick! interesting. I can't even imagine how that would work. Of course it would take some getting used to, but it could be more comfortable, easier and more responsive than a wheel. I guess that's the point?

generally hydrogen fuel cells haven't worked out.

The storage density is too low and and the catalysts are touchy.

If they can make a fuel cell work on LNG or Propane or Ammonia, but,

hydrogen gas seems wildly impractical

Liz, I was particularly intrigued by the Roadster buggy's use of drive-by-wire technology. It has a joystick instead of a steering wheel. For years, engineers have told us that drive-by-wire allows us to do away with the steering wheel and replace it with a joystick or some othr device. Well, here it is.

I agree, Debera. The Mercedes F-Cell Roadster is eye-catching. That's why we led off with that photo. Leave it students and trainees to develop a vehicle so unique.
