But your efficiency calculations do not include the use of solar power for hydrogen production.
Sure solar is ineficient, but the solutions that are almost available now remove #'s 1 and 2 on your list, and beyond the price of the cells it is virtually free.
So by your formula - solar production of hydrogen burned directly in a combustion engine, is almost equal to burning fossil fuels.
United Nuclear is developing a system that uses solar panels to produce the hydrogen via electrolysis - 8 - 2' x 4' panels is all you need for 1 car. http://www.switch2hydrogen.com/
There is also a company based in England that has a direct solar to hydrogen panel that flows water through the cell and produces hydrogen. http://www.hydrogensolar.com/basics.html
So please revise your calculations and factor in that the fossil fuel to hydrogen option is not the only viable option.
As a person who suffers from learning disabilities, but who has been in the IT world a long time, I can say that I frown on the idea that is behind the certification tests.
I can't take tests well, it's just the way I am, but that doesn't mean I don't know what I'm doing. The real world results of my work has proven that I can do the jobs I am asked to do.
I also have decilned to participate in the tests, because it is quite obvious that a large portion of the process (and profit) was learning how to take the tests not whether or not you knew the materials.
I was at a small consulting firm that started down the M$ certification pathway, and I still ended up knowing way more than almost all of the consultants who took the tests, even though I was the only one who refused to take them.
So in the end, I'm sure I could have made more money if I had played the "certification" game, but it was not worth the stress the testing would have caused me.
That said, I whole heartedly endorse training, hands on classes, and learning in general, just leave the "certification" testing out of it.
They aren't special - every/.er knows that - but if you too owned an ISP (think hotmail and MSN) you could sue him to.
Besides they are just putting on a show for the government and the users to try and look like they are good guys. After all, they helped create the problem in the first place with bug ladden OS's.

All I can say is thank goodness for spellchecking ;)
