Sahimo Hydrogen Vehicle Gets Over 1,300 mpg 453
Mike writes "Students from Turkey's Sakarya University have unveiled a remarkable attempt at creating Europe's most fuel-efficient vehicle. Dubbed the Sahimo, their pint-sized hydrogen car is cable of eking out an incredible 568 km on 1 liter of fuel (about 1,336 miles per gallon). An aerodynamic carbon-fiber construction keeps the vehicle's weight down to less than 110 kg (243 lbs), and the designers hope to push the Sahimo's performance even further to a full 1,000 km per 1 liter of fuel before participating in the Global Green Challenge in October."

The math simply isn't there. 2.3L of H2, even using our best portable fuel cells to equal 1L of gasoline. Complicate that with storage costs, refrigeration, transdportation issues (how do you pipeline something that needs to be kept as under -240 celcius or at over 930 ATMOSPHERES of pressure?) and then there's the whole "driving around in a bomb" thing... not to mention dealing with trapped H2 gas in the ceilings of parking garrages, your home garrage, and other places it collects and explodes in. H2 is simply NEVER going to be an acceptible fuel for humans except possibly for running giant scale fuel calls at sites where H2 can be produced and stored on-site.
If the math was better, if we could make and store H2 for say 10% of the costs of using gasoline, then it might be worth the costs and risks to build the rest of the infrastructure, but here's another tidbit: Filling a fuel cell vehicle tank with enough liquid H2 to travel 200 miles TAKES 4-6 HOURS! (unless you're talking running a full refrigeration system in your car, and keeping the feul liquid by temperature instead of by pressure).
Well, we can't keep using gas, can we? Actually, yes... See the research from dotyenergy.com. The problem is we're using gas from OIL. This is CO2 that ISN'T in our atmosphere yet. If we could use CO2 from EXISTING sources (sequesterd CO2), and run that through an RWGS/RFTS process (in use since WWII), we can use wind energy to MAKE fule, clean, cheap, safe, fule that adds no ADDITIONAL Co2 to the atmosphere. This CAN be done for about $60-80/bbl depending on the local market. It can be made right here in your own town, the process is so safe it barely even ping on the EPAs radar (about as polluting as your local corner gas station, except a plant makes anough fuel to support about 10,000 drivers), and we could have it TODAY! (this is all proven science, not pipe dreams).
Doty has figured out how to simply put all the pieces together. Actually, he did that 20 years ago, and then spent the next years figuring out how to make each piece of that puzzle more symbiotic to other pieces, how to make those pieces more effieint, and in the end got 60 World patents issued for the technology.
All they need not is a measly $5m to build a true scale plant (instead of a lab experiment), to actually prove to the world on a large scale that the number do in fact refelct the science we've been using for 50 years... simple.
After that, anyone can buy a fuel plant (150-250m), hook it up to a small wind farm, (175MW or so), and make tens of thousands of gallons of fuel a day. Big Oil can't have a monopoly. We don't have to import fuel. It;s cleaner fuel (no sulfers or other contaminants, since we're starting with only H2, CO2, and H20.
This is a dream process. But, since it;s not a BIO-fuel; since it uses H2, but NOT as a fuel source itself; since it USES wind, but doesn't develop wind energy; since it makes gasoline, not an alternative fuel (actually, it makes ethanol, propanol, methanol, and a bunch of other hydrocarbons, which are seperated and used for multiple industries); since it's not a hybrid car technology; they don't qualify for a single current government program to help fun their first small scale plant. they need investors... (or pressure on the government to give them a grant).

I am NOT an investor, nor am I copmpensated in any way by Doty or any affiliates... I simply want this technology to see the light of day.

It takes more energy to make hydrogen than what you get back out of it. You can't make this at home. But you can make electric power at home, for free.
Hydrogen fuel necessitates a distribution network exactly the same as for petrol. This is why the oil crazies in the Bush regime pumped money into hydrogen and nothing into electric, even as electric cars worked and people loved them to death.
Plus, it's unbelievably explosive - in concentrations between 2% to 98% it's explosive. So you either must have none or very close to 100% hydrogen for it not to explode. Now, when gasoline turns into a vapour and creeps along the ground then explode if lit you can get a 30 foot or more radius is vapour with corresponding explosion as the vapour ignites. And gasoline is a fairly heavy dense molecule compared to hydrogen which is the lightest molecule known, and since it's really a gas, unlike gasoline which will sit there as a liquid for days, hydrogen turns from a liquid to a gas in much less than one second.
If you have a tank with 5 gallons of hydrogen and the tank is ruptured - and eventually this absolutely is going to happen one day - then the resultant break and explosion would very much on the order of what is definitely not conducive to human life. That is, you'll be ok unless that tank goes, then you're pretty much a goner, much more so than with gasoline.
Between the fact you have to buy it from the oil barons and can never make it your self for free and is the most explosive substance known, yeah, hydrogen is great. Not.
I think if we knew what we were doing we'd immediately stop anything to do with hydrogen cars and stick to electric. Keep in mind before the oil companies paid the car companies to stop making electrics, there were more electric cars than gas powered cars on the road in the early 1900s.

In fact, despite the hydrogen in the Hindenburg completely burning in less than a minute most of the passengers and crew survived (the diesel continued to burn for a long time afterwards)
Secondly, it's much lighter than air. This means that leaks and flames go upwards, unlike a gasoline spill that spreads out over the ground while it burns.

This stuff doesn't work.
Why ahsn't this gone to mass production?

What about the problem where in HHO takes more energy to create than it expunges? It's pretty simple physics. The electrolysis process to generate HHO requires something like ~280 Joules per mole and HHO only produces something like ~240 joules per mole. It's been a while, but when you also factor in friction in the cylinder, inefficiencies in heat, etc, it gets worse.
Have these problems been solved?
