Bit of an old one, that image, but I thought it demonstrated the complete non-connectedness of the average greenie brain quite well. In fact, it's so completely batty that i suspect it's an infiltrator with a spoof placard.
A question - what would you rather be travelling on if it was involved in a crash?
1) A conventional diesel engined bus, or 2) One containing several tanks of hydrogen under considerable pressure?
And the "Greenies" need reminding that hydrogen takes lots of energy to liberate it from water, so the big "Zero Emission" banner is bullshit. It's only zero emission AT THE POINT OF USE...
I'm happier in a diesel vehicle than a petrol one, for just that reason. However, LPG vehicle tanks are designed to withstand huge impacts and their safety record is excellent. I can't imagine H tanks being any different.
Your last point is a good one. As with electric cars and bioethanol, the total energy use and total pollution is probably the same, but it looks better, and that's what counts.
AS soon as all the protesters give up all items made with petroleum there will a great drop in the demand and the prizes of fuel will go down - yea! That will mean I can ride even more! They have no idea that they are protesting there on consumerism. Crazy logic.
The best hypocrisy is the "Atomkraft Nein Danke" slogan that is printed on a picture of a smiling sun - this campaign is big in der Vaterland (Germany).
I was taught in Physics that the sun is a huge atomic fusion reactor that chucks out nasties that cause skin cancer etc.
No doubt someone will tell me I'm wrong, but LPG (usually propane) is stored in liquid form at no more than 100psi. Hydrogen won't remain in liquid form without refrigeration, and so in vehicles is stored as a gas at (I believe) anything up to 3000psi...
If a Hydrogen tank ruptures the contents will mix immediately with the surrounding air and become highly explosive (think Hindenburg). Propane has to vaporise first, and being heavier than air will initially remain at ground level (like petrol). Also, like petrol, in high concentrations it will not ignite.
Diesel, on the other hand, will put out a naked flame...
There is the other matter of a small leak igniting, but not being visible, as hydrogen burns with a clear blue flame. I imagine they will have to "dope" it with an artificial smell if large scale use ever happens.
Atomkraft Nein Danke - hey, I had one of those on my 2CV in the early 80s. Really.
MD - your understanding of the subject is clearly better than mine, and of course you are right. Propane is pretty safe if it's in the right container, but 3000psi - blimey. I suppose it's better then those huge floppy bags that they used to have on the roofs of cars in WW2.
Buses don't run on oil, in the placard-holding moonbat's world? What does she think they run on, then?

ReplyDeleteWho needs oil, I ride the bus?
ReplyDeleteJust when you think you've heard it all...

ReplyDeleteMoonbat (presumably) thinks they will all soon be Hydrogen powered...
