Maybe I'm jumping to conclusions here, but it is good to see that auto companies are engaging alternative designs (even if it is just an exercise) WITHOUT government subsidies.

I agree that it is mostly an engineering exercise.  But, I guess we need to start somewhere.

Your slide shows are always fun.  Thanks for the article.

Bronorb, you've used the exact right word to describe this technology: engineering exercise.

I'm with you, Thebox808. I can't imagine we'll see a hydrogen infrastructure. As for explosions, I didn't realize that was an issue with these vehicles.

Excellent post Charles.  The company I have a partnership in is now producing our REV 7 on-board hydrogen generator.  Our concept will be to "bleed-in" H2 and combine that will fuel promoting improvement in gas mileage.  This is not a fuel cell but an installed device producing hydrogen.   We have five trial installations so far that generate a 17% minimum improvement in mileage.   The package also includes data retrieval so carbon fuel credits can be "booked".  It also gives the transportation company indications as to actual savings and information relative to long-haul and short trip numbers.  We are working towards installation on 300 and 400 HP diesel engines.  These typically get 5 MPG so; any improvement would be a significant cost savings to that industry.  Many thanks for the information and it's good to know what others are doing along these lines.

Good point, theboz808. It's not the first time someone jettisoned the steering wheel.

There are still some hurdles for Hydrogen powered cars to be commonplace on the roads, however don't be too quick to discount them.  All that is needed is an efficient system for extracting Hydrogen from water that can be used on board a vehicle and all the storage problems dissappear.  In fact filling stations would also dissappear as all the vehicle owner needs to do is top up with water from the tap at home.

The nay sayers will talk about this being impossible, but look at the technological achievements over the last 50 years and consider what has been possible that people thought could not be done.

Good point, Ttemple. Or, let's see how it would do in a fender bender with a massive SUV. I like the idea of smalling down cars, but that's only positive until you come in contact with an SUV.

This is a cute engineering exercise but my advice to auto makers is to put these cars in their respective museums right now as an example of an evolutionary dead-end.

As mentioned above, this technology will never scale to the point of providing hydrogen "gas" stations that our mass motoring public could take advantage of. Elements in a gaseous state (also mentioned above) are difficult to maintain and transport. Can you imagine how expensive it would be to transport compressed hydrogen gas from point A to point B?

The real problem with this technology is cost. It's extremely expensive to make, store, transport, and dispense hydrogen gas SAFELY. It will never progress beyond the few science experiments you see in this slideshow.

IMHO, of course.
