"...Hysun 3000 (http://www.strangecosmos.com/content/item/102941.html), presented at the recent Fuel Cell Congress in Stuttgart, drove from Berlin to Barcelona..."We wanted to subject the car to the demands of normal driving, with unpredictable weather, temperature and traffic conditions"..."

Apples and oranges.

They say it's equivalent to 12 litres of petrol, so it's actual gas-mileage is around 150mpg. But then again, look at the car. It's a single-occupant vehicle apparently designed solely for fuel efficiency, not practicality. Scaled up to a proper passenger vehicle, you would probably see a lot less efficiency. And then, what amount of petroleum hydrocarbons were burnt creating the fuel?

It looks a lot like the GM Lean Machine concept car. Totally cool, but utterly impractical for most of us. That sucker's like a tiny little slot car. Can you imagine trying to drive that on the interstate surrounded by semi's and SUVs? :o

Yes, it would be about the size of a motorcycle.

For putting this together in their spare time, it's a pretty impressive start, it seems to me.

How do you figure?

1800 miles per 12 liters of petrol is 150 miles/liter.

I don't understand what they mean when they say it's "equivalent to 12 liters of petrol." Are they really saying that's how much this car would burn in 1800 miles if it had a regular internal combustion engine? From the context, it sounds like they're trying to express how much more efficient their car is than other fuel cell cars, so I wonder if they mean that for a fuel cell car to drive as far as they did on the amount of fuel they used is the equivalent of a gasoline car driving the same distance on only 12 liters. These two interpretations may add up to the same thing, but only if the efficiency of their car is entirely due to its smallness, rather than the design of its engine.

Am I making sense here? It's hard to articulate this.

maybe they're are just talking about calorie content

Oops. I wasn't paying much attention.

I say, sit back and watch. Although the car itself is fairly impractical, it looks like promising start (assuming that this isn't Bovine Digestive Biomass to begin with). Give them a chance to develop their system into something more practical, and see what kind of performance figures come from it. They just might be on to something.

Certainly any article that describes a quantity of hydrogen as X number of gallons is not terribly scientific.

By the way, where is the reference to 12 L of petrol. That isn't in the story when I open the link. Has the story been changed??

It's still there.


"We have achieved a world record distance using hydrogen," said Hysun spokesman Joerg Schweigard.
"A fuel cell driven car has never traveled this far on public streets with such low fuel consumption - the equivalent of twelve liters of petrol."

Well, there goes my "reading comprehension" test score.... :oops: :oops:

Hmmm. If that thing can tow my boat I might be interested.

Pretty impressive, even if it does look so strange that I'd never want to drive it.

He might like a bit of the cryogenic stuff on a hot summer's day.
