When pitting an FCEV against a BEV both charged from an electric source, the power plant and motor are the same, so they cancel out. The BEV has a battery (obviously) and transmission line losses, since an electrolysis plant will be located beside the power plant. Each of those are about 95% for about 90% efficiency. The electrolysis of water is about 25 to 40% efficient. Then the hydrogen has to be compressed (85%) or liquefied (60%). Then it has to be piped to a fuel station (90%). Then is has to be converted back into electricity (40 - 50%). That makes 5 - 15% efficiency.
No one has tried to produce hydrogen on a large scale from solar energy because it's economically infeasible, and will be until fossil fuels cost about 10 times what they do now.
As soon as you switch to renewables, hydrogen craps its pants. Anything inherently electrical like solar or wind will be 4 times more efficient charging batteries and there will never be enough waste biomass to drive all our cars. Unless you're growing biomass specifically for fuel, in which case you're using a lot more land, water and fertilizers (made from hydrogen) than a few more solar or wind farms.
you mean centralize fossil fuel burning at a single plant instead of distributing is across thousands of cars.
Great, now in addition to cracking/steam reforming, liquefying/compressing to 10,000psi, piping/trucking and squeezing it through connectors foolproof enough for the average fool to operate, we have to make millions of tonnes of dry ice, bury it and keep it frozen for the rest of eternity.
It's absolutely trivial to generate lots of random numbers:
Tune a radio between stations.
Plug it into your sound card.
Hit record.
Wait a few hours.
????
Gigabytes of randomness.
You have to be a religious zealot to believe that a 60 year old man should be incarcerated for trying to bang an adult police officer pretending to be a 13 year old girl.
Oooooh, we can use imaginary victims now? lets say you're an alcoholic. Next week you might get drunk, drive home, get in an accident and kill 6 people. It'd be faster to just jail you for life right now.

Converting fossil fuels to hydrogen doesn't.
CH4 + H2O + heat -> CO + 3H2
CO + H2O -> CO2 + H2
Nearly 50% of power generation in the US comes from coal too.
Except that batteries are already cheaper, more available and at least 4 times more efficient than hydrogen.

Just charge a battery and be done with it.
yeah, all that nasty carbon stuff is behind the curtain where we can't see it.
Fortunately all gases are exactly the same.
If a tank ruptures the hydrogen quickly escapes in to the air forming a fuel/air explosive instead of sitting around for hours waiting to be ignited.
FTFY
Translation: I like buying 100 times more computer than I need and only being able to use 1/100th of it at a time!

In no particular order: What's with the assholery? How am I supposed to know you're agnostic? What does that have to do with anything?
Do you have intimate knowledge of this case? Are you a mind reader? Or do you just want to see someone hang?

This is a pretty funny picture. Someone should put it on a T-shirt.
Fun fact: the amount of money drug companies spend on research is about half of what they spend on advertising.
Madden doesn't have anything to do with running while holding a ball and getting your face smashed into the ground.
-1 the exact same joke gp made
i do not cower. you're an ignorant hypocrite.
i am michael kristopeit.
ur mum's face're completely pathetic.
He's in the media spotlight. It would be pretty difficult to just "disappear" him, unlike some other people.
why do you cower? what are you afraid of?
you're completely pathetic.
who's laws?
Being a fuckwit is a crime where I come from. Hop on a plane and come stand trial.
The U.S. can deal with him when he gets out of jail.
Sorry if I'm not up to speed, but what does the U.S. have to do with anything?
