dear friends,

imagine to have a hydrogen fueled car and a conventional gasoline-fueled car.

suppose that the fuel tank of both cars has a leakage, and that the fuel begins to burn.

would you prefer to be inside the hydrogen-propelled car or in the nowadays gasoline-propelled one??

give and answer and then read this document (pictures at the end):

Also , if you'd have to test run the cars, would you rather do the oil or H car ?

Also would you mind buying a new engine for your H-car every 200 miles? Cause that's the life span of such an engine.

Hydrogen is not the awnser!

Also, it is more "fuel"-expensive to produce hydrogen, than just use the fuel in conventional engines.
This also goes for Bio-Diesel.

for more myths about hydrogen explained and confutated, read this
http://www.rmi.org/images/other/Energy/ ... nMyths.pdf

a lot of what people think about H2 used as fuel in cars is wrong (efficiency, cost, lifetime, etc...)
almost all technological problems have been solved... fuel cells and electric engines have very high efficiency.
of course... it remains the 8BIG!) problem on how to conveniently produce hydrogen... and the "chicken-egg" problem... would you buy an H2 car without H2 filling stations in your country? and which company would build H2 filling stations without noone having H2 cars?

i don't know which is the answer... but certainly we have to think "beyond" oil...

a very interesting (and huge!) lecture is this one:

"winning the oil endgame"

regarding biodiesel...
i recently made some calculations, and it emerges that, if we consider nowadays oil consumption used for transporation only, USA alone would have to harvest about a half of their surface to get the biodiesel required for all its cars/trucks/etc...
the france itself, as well as italy, would require a surface greater than their total land area!

fortunately, it is possible to get biodiesel also from algae, with a much higher efficiencies

i didnt know this latter, it seems really interesting!

"But five, soon seven, billion people in poor countries, whose
economies average more than twice as oil-intensive,29 want the same oil to
fuel their own development."

Do you see the danger the world is heading to ?

Some pointing to a solution me be:

Maybe that's the new way of life...

absolutely...
that is only one of the hundreds of problems that we must face in the following decades...
as i said before, i don't have answers, only questions!
however, i am lucky to have the time to read and study about these problems, since they are related to my work...

Is it a song your writing ?

!?!? what do you mean?

I mean , what does "hydrogen fueled cars" have to do with your work ? what work ?

That would have been a more clear question

I wonder if carbon based fuel would ever pass the security tests if it were to be subject to approval nowadays, for either safety or environmental issues.

i have a grant in a research institute, and we are working mainly on solar cells. but we gather and read informations also on renewable energy in general

Interesting.

Solar Cells,
aren't they made out of oil too?

That goes for spirits and cigies too.....

hydrogen is safer than gasoline for sure...
