Fill 'er up

Picked out from the net...note the date...

At the moment, you'll be able to fill up your 2017 Toyota Mirai about Toyota Mirai about Toyota Mirai for $16.63 per kilogram. That's a cost per mile of around $0.33based on the average consumption pattern. Toyota Mirai FAQs. Aug 28, 2017

Post #1 was showing .price of $1.57 / kg..
Where is the $16.63 coming from?
 
Who will be the first idiot to be smoking a cigarette when filling up........

We will try not to confuse you 2.2 lb same as 1 kg if the 454 grams to a pound did not compute
 
Lets not compare the paper maccha structure of the Hindenburg to todays fuel cells which are not about to explode any more than a lithium-ion battery at a few hundred volts.

I just saw my first and only toyota fuel cell vehicle a couple days ago. I thought it said "Mirage".


On a serious note, when they first came out, they were lease only, and i think toyota paid the fuel bill.

Co worker has one. we call it the h-bomb.
Hey Jose, let's take the h-bomb to lunch.

And what happens to the idiots smoking while filling with gasoline. Propane and hydrogen fill as sealed connections to make things as idiot proof as possible. The connections are designed so no gas escapes.

It is true, Hydrogen is much safer than gasoline while filling up at the stations for the reasons stated above. Not only that, Hydrogen if leaked out goes straight up into the atmosphere in a column at about 40 to 44 miles per hour. It does not wait around to be ignited like gasoline.

Hydrogen is 29 times lighter than air. With gasoline vapors being heavier than air, the fumes sink and linger and are much more likely to ignite and explode than Hydrogen.

The Hidenberg caught fire not because of the Hydrogen, but because it had touched the electrical tower which sparked and ignited the cloth/nylon skin which encased the Hydrogen.

If you watch the actual footage of the structure going up in flames, you'll notice that it did not explode like a Hydrogen bomb as everyone seems to say it did.
As PurpleBeeper stated in post #12, the Hydrogen would burn straight up and evaporate in less than a second. But in order for all of it to burn, it would have to burn BEFORE it mixed with the surrounding atmosphere. Once it is mixed or evaporated into the atmosphere it will no longer burn.

If you have never seen the whole news footage of this airship burning, you owe it to yourself to Google it and watch it. When you do, you will see that there really is no explosion. If there was an explosion as everyone says, the tower would have been blown away. Actually,there would have been nothing left there in a split second.
You see the airship slowly falling to the ground, as its skin burns. Then you would see that they wooden framework was on fire and not blown to smithereens as most would think.

Hydrogen is some nasty ****! If I was a Firefighter and came across
a fire with Hydrogen involved, I think I'd run the other way! Very explosive
and un-stable when it gets loose.

It is no more nastier than gasoline. Actually, gasoline fumes from a leak are more likely to ignite and explode before Hydrogen would.

The reason being the Hydrogen will escape and move through our atmosphere so fast because of it being 29 times lighter than air. It would be harder to ignite the Hydrogen, unlike the heavy fumes of gasoline collecting just a few inches above your whole garage floor waiting to be ignited like a bomb by a spark or a hot water heater pilot light. Unfortunately most people do not realize the real danger of the heavy fumes of gasoline, natural gas and or propane pose to the unknowing. I would rather be around a leaking Hydrogen vessel than any fossil fuel leak anytime.
 
It is safe until you heat the tank and it ruptures the expansion is the killer not the fire
 
While the thought of using hydrogen seems appealing at first glance (some people think it makes only water vapor when it burns) it really isn't a great fuel for engines. There were some hydrogen powered buses running around Vancouver during the 2010 Olympics for clean propaganda reasons. BMW had their 7 series hydrogen powered V12 car 12-13 years ago too. It was a flop. The gasoline version put out 440 hp. while the hydrogen version managed 256 hp. And to get there, it got 4.7 miles per gallon. Hydrogen is prone to detonation, not a great internal combustion fuel. And burning it in air instead of pure oxygen still results in NOx emissions - more than burning natural gas due to the higher flame speed.

However, most hydrogen cars don't burn it in the engine. Instead it is used in a fuel cell that produces electricity. Hyundai, Toyota, Mercedes, Honda are all working on fuel cell cars. Nice. It's still an electric car. And while hydrogen is abundant in the universe, it isn't on Earth. If you have enough electricity available, you can split water to get the hydrogen out. But that isn't the way most hydrogen is made for commercial use; it's extracted from natural gas with the left over CO2 being dumped, because that is the cheaper way of doing it. And even so, the energy it takes for the process is more than you get out of the hydrogen in the end. Perhaps 10 million tons of hydrogen is used in the US each year for industry and commercial purposes - to switch cars to that fuel would increase the demand to ten times that amount.

By the way, German engineers knew of the risks with hydrogen, the Hindenburg was originally designed for Helium. However, the majority of the world supply came from the US and due to the ban on export, (the helium act of 1925 https://en.wikipedia.org/wiki/Helium_Act_of_1925) hydrogen had to be used instead. After only 32-37 seconds of fire, about all that remained of the main ship was the aluminum frame. But even after that it should be remembered that 2/3 of the people on board survived.

You guys have enlightened my education on Hydrogen. All I knew was that the stuff can make a big BOOOOOM! if not used correctly.

You have got to have the ability to split atoms to create a big BOOOOM with hydrogen.
 
some pretty good info :thankyou:

we have some really knowledgeable members here :drinks:
