Turkish Students Create Hydrogen-Powered 1300-MPG Car

Popular Science wrote:
In preparation for the inaugural Global Green Challenge across the Australian outback, a team of Turkish students have assembled a hydrogen-powered vehicle that has an efficiency of 568 kilometers per liter (roughly 1,335 mpg). In order to get across the outback, they hope to only use three liters of fuel in the vehicle, dubbed the SAHİMO.

The SAHİMO weighs 110 kg--a carbon fiber frame keeps the weight down--and the scary thing is that these Sakarya University students want to up the efficiency to 1,000 km/L.

Why the hell don't we have these on our highways now!!! I know Obama killed the Hydrogen car, I don't know why.

Getting hit by a semi in that would be pretty painful.

Both are death traps. But the Smart Car only gets 33/41 mpg...less than a Toyota Prius that gets 51/48 mpg.

I think the smart car cost a little less than $170,000. .. there really isn't much in the way of details neither. At least not in the article you posted.

It is very difficult to build hydrogen tanks capable of the pressures needed to make hydrogen a viable alternative fuel, as hydrogen has such a low energy density.

I'd rather get the Hybrid Milan than a Prius tbh.

Our family has a normal milan ('06) now and it's nice...but it only gets like 18 MPG.

This.

seriously, people. Hydrogen is not viable, not least because it's so damned hard to liquefy.

Except there are developing technologies that can chemically seperate hydrogen from water, using some strange alloy (I will try to look it up later). This means that you can get hydrogen from water without electricity, and you can carry your hydrogen in a non-pressurized container in a crash-safe form.

Of course, there are still a lot of issues with it, but the technology does exist.

The pressurized container/flammable gas is not a safety issue. As it is you drive around with 10-20 gallons of some very explosive stuff under your seat.

If I remember correctly, the hydrolysis helped, but still did not really solve the energy density issue.

By weight, hydrogen has the highest energy density. The problem is, as FM says, is getting to be a liquid.

...but who gives a fuck about weight when we're talking about cars. The problem is getting around having a tank that is the size of the car.

wut if they made the semi trucks the size of those two little cars? eh lol or if they used some lighter material to build other trucks so during impact ones survivability is higher

a) America =/= world. Germany and Japan both dabble in this tech, but it's slow progress with good reason rooted outside of politics.

b) So? a Ford Focus will return better MPG with better safety than a pickup truck - you're comparing apples and oranges. The Smartcar's main purpose isn't to be some super-eco car

When we use the most common way of making hydrogen, from fossil fuels, it's impact on our dependence on oil and greenhouse gases is the same as using gasoline for cars. Now you can also get electricity from solar panels and use that to perform electrolysis on water to get the hydrogen, this method is much cleaner and eco friendly.

The seperation is probably the bit where technology will improve massively... but I still don't see any way to liquefy the damn stuff and make it useful as a fuel, cheaply.
