You bet, including his ridiculous rant in the comments section.

yeah.

what he said

good luck on that Hydrogen thing...

Priming the comment pump: Hydrogen advocate calls out pro-plug-in ABG readers [w/POLL]

New poll from Greg B. It's supposed to be hydrogen (FCHV) vs BEV (iMIEV) vs PHEV (Prius).

Notice the vehicles he chooses to represent each segment.

I suppose autobloggreen is doing this because hydrogen vs plug-in arguments usually drive up the number of comments and probably also views.

Greentech Media: Will GM Abandon Hydrogen Cars?

California's Gov. Arnold Schwarzenegger announced the "Hydrogen Highway"...
That program hasn't been successful – there are 25 pump stations that have been built in the state, Barthmuss said. But only a handful could completely fill out GM's hydrogen demo car, the Equinox, because of the varying amount of pressure used to compress the hydrogen gas (10,000 psi for the Equinox versus 5,000 psi being dispensed at many pumping stations).

So they have standard issues as well. Beside the obvious different connector issues the have Pressure Differences to deal with as well.

At least an electric car can carry a handful of adapters and can handle 120V to 240V at various amperages.

I love my Roadster, but sometimes I need to carry more than one passenger, or carry cargo, or drive in the snow, or some other function for which the Roadster is not well suited. So, I also have a big 'ol SUV. I hope someday that I can swap that out for something that doesn't consume gasoline (or diesel).

The Toyota FCHV that Blencoe is promoting happens to be an SUV, so I couldn't resist posting my thoughts on what it would take for me to buy it when it is supposed to be available in 2015:

1) It is actually available in 2015
2) It's for sale, not lease
3) Price is under $125,000
4) There are at least 1000 public filling stations in the US (Note, currently there are approximately 120,000 gasoline stations)
5) Public filling stations are available within 20 miles of both my home and work.
6) The price of a kg of hydrogen is no more than $1 more than the price of a gallon of premium gasoline.
7) There is no battery electric SUV available that can go 300 miles on a charge and recharge in 30 minutes or less and costs less than the FCHV.

The hydrogen industry has a very long way to go on every one of these points. I give it at least a 50% chance that NONE of those requirements are met by 2015, and about 1 chance in a million that all 7 would be met.

Sinking Finances Throw Iceland's 'Hydrogen-Based Economy' Into the Freezer - NYTimes.com

If Iceland can't make it work with their abundant geothermal power then no one can. No surprise there, just further proof that hydrogen is not a practical option.

I think you've got it! Dump the fuel cell and go straight to Mr. Fusion!

Then, you'd be trading a hydrogen technology that's 10 years out and always will be for a (much better) one that's 30 years out and always will be.

(Yes, I'm way behind in this thread, but I just couldn't resist. And, I've always wanted a Mr. Fusion, to the point that I actually worked out the energy per kg of banana peel once.)

Producing hydrogen from urine

Quote:

Botte uses electrolysis to break the molecule apart, developing an inexpensive new nickel-based electrode to selectively and efficiently oxidise the urea. To break the molecule down, a voltage of 0.37V needs to be applied across the cell - much less than the 1.23V needed to split water.
