People think that hydrogen is a potential new energy source. It's not. It's only a potential new way of storing and retrieving energy for use. And if it becomes an efficient method of storing energy, then it may become a good alternative for powering cars.
I can imagine, for example, if the technology were created to efficiently and continuously produce sufficient hydrogen in the home from the domestic water supply, gas stations might become obsolete. You could just store the hydrogen in tanks in your home, hook up your car to refuel, and go on your merry way.
If that technology existed, I would almost certainly get a fuel cell car.
It might also provide an economically effective way to get electricity to remote places, especially those that have abundant sunlight, which could be used to split water into hydrogen and oxygen.
Just remember that the second law of thermodynamics has not been repealed, although Obama may just try to do just that, too, without Congress.
Every human has a desire to be righteous, ie, right with God. It’s a desire He “wired” into us, “written on their hearts”.
Some strive for it through their works.
Sheeperals strive for it through their advocacy.
Christians know that the only way to achieve it is not through striving, but imputed through Christ.
It fully explains why, when you point out the failings of policies that liberals support, they act as if you’ve personally attacked them, because you’ve kicked the stool out from under their sense of righteousness.
So if I read your post correctly, this new tech may make hydrogen fuel cell vehicles comparable in lifecycle costs to gasoline powered ones?
Which means that the big benefit will be in promoting national energy independence. We can use internally available natural resources (coal, natural gas and oil from fracking) and/or nuclear power to produce the hydrogen for the fuel cells. And tell the Arabs, Venezuelans, etc that they can go drown in their oil.
They don’t teach the First Law of Thermodynamics at Stanford?
Obama repealed it with an Executive Order.....................
Solar cells to provide the DC voltage for producing the hydrogen (and oxygen as well, to be vented off) stored for night time use to light your garage while working on your Time Machine.....................
AND........Thats when you know this person is deriving their advocacy from their self-righteousness....................
That sounds great, until you realize that the efficiency number is just for generating the electricity.
You still have to drive a motor and a vehicle drive train with it to make the vehicle move, and there is a lot of efficiency loss there.
Folks This is a Joke.
Please its not April Fools
1. You can’t win. You can only break even.
2. You can only break even at absolute zero.
3. You can’t reach absolute zero.
I think IC engines are at present a good deal more efficient than 10%, at least some of them. Hard numbers are difficult to come by because of different ways of figuring efficiency.
I’ve just never understood the mania for hydrogen. If someone discovered a new law of nature whereby the molecular bonds of water could be broken using greatly reduced energy, then we’re in business. Possibly some type of catalytic reaction?
But it seems VERY likely this would run up against the laws of thermodynamics, which nobody has figured out how to break yet. Without such a legal breakthrough, it’s a dead end, and should obviously be such to anybody.
Just figured out what we need. AAA battery powering a catalytic converter using an unobtainium reaction to split the water molecule.
Fill up the tank with a garden hose!
Cui Bono as you noted, can benefit different groups and at different levels. Real levels and perceived levels, again as you noted.
Something I haven’t seen addressed here. For hydrogen to be a practical fuel, at least for transport purposes, it has to be highly compressed, or possibly liquefied. (I’m a little vague on the details.)
Unless I’m even more vague than I think, compressing gases this much requires a LOT of energy. Which might pretty dramatically impact the “efficiency” of the system as a whole.
In fact, I’ve seen plans for cars designed to simply run on the energy stored in highly compressed air.
Natural Gas Power Density> 0.044 - 0.0562 /b/ft3
Is this satire??? We did this stuff in middle school chemistry. I see they got in the obligatory “a fossil fuel that contributes to global warming.”
But we can’t burn hydrogen in our cars. It produces dangerous Dihydrogen Monoxide as an exhaust gas which is WAY worse for global warming than natural gas.
Actually, there is a real “flux capacitor”. And it looks nothing like that picture.
New hydrogen storage technologies that do not require compression of the gas are being developed. There are materials that ‘soak up’ hydrogen like a sponge does water and hold it inside a molecular matrix until it is released by heat or some other trigger mechanism.
Storing pure hydrogen, gas or liquid, presents problems in the storage and transportation arena. Metals exposed to pure hydrogen for prolonged periods develop ‘hydrogen embrittlement’ as the hydrogen atoms are small enough to migrate right through the solid metal and escape, like termites in a 2x4.....................
