VW may have developed a major hydrogen breakthrough...cars could travel 2000 km on a single tank of fuel.
VW often rails against hydrogen cars, but the German automaker is reported to have filed a patent that could mean a major breakthrough for hydrogen powered vehicles, reports Patrick Freiwa of the German Kreiszeitung here.
Though the latest trend has been electric cars, these have also a number of technical drawbacks like range, cost, mining and weight. Moreover there is also the problem of how to dispose of millions of tons of batteries at the end of their lives.
Files patent
Despite VW having railed against hydrogen technology for cars, the automaker has "filed a patent for a special fuel cell with the Saxon company Kraftwerk Tubes GmbH," thus making it clear that the auto giant is indeed pushing hydrogen technology. With the new technology from VW, the company looks to set itself apart from the rest of the field, which has focused on fuel cell technology.
According to the Kreiszeitung: "The main difference to the fuel cells of Hyundai and Toyota is that VW has set on a ceramic diaphragm instead of the usual plastic diaphragm and is the only manufacturer of this technology that produces the ceramic membrane in such a way that the fuel cell can be started quickly."
The advantages are lower production costs and the elimination of platinum.
Up to 2000 km range
"The target for the breakthrough of this form of mobility is considered to be the so-called solid-state cell battery," reports the Kreiszeitung. VW predicts shorter refueling times with the innovative technology.
"We can travel up to 2,000 kilometers on a single tank of fuel," says the VW engineer Sascha Kuhn.
If true, electric cars will be left in the dust.

As for science, yup I'm clued up.
CO2 is not poisonous; as a gas, CO2 itself will not hurt you.
The human breathing mechanism actual revolves around CO2, not oxygen. Without carbon dioxide, humans wouldn't be able to breathe.
It's a (the?) main product of metabolism. You could claim it's a hormone, as it's generated at one site and has an action at another; it's ubiquitously present, as with oxygen release gradient to tissue level, pyruvate's fate in the TCA cycle, and fatty acid oxidation to acetyl-Coa heading there, too.
Now required to be off-set or sequestered somehow... Perhaps buried. Also, plants crave it. They need to get their fix.
hot air!
..
they're rigged up to drop horse puckeys.
I'm jumping for joy at this one.
We really are gonna make it as a species, we are almost there - what good news!!!
I don't think they're even talking about a combustion engine, so their "tank of fuel" is apparently however they're charging the battery.
Just from an energy balance stand point, when viewed from the point of H2 extraction out of a hydrocarbon (oil, gas) through its treatment, compression, transport and then local re-compression, consumer H2 as a fuel is exceptionally inefficient.
Inefficient and dirty. If you are talking about hydrogen extraction on a scale this large, there will be a lot of hydrocarbons being refined and you don't use electricity to do that; you burn more hydrocarbons.
This is without considering that hydrogen gas contains 1/4 of the energy found in methane gas and almost 1/10 of what is found in propane gas. Given the low energy density, hydrogen must be stored in a vehicle at or above 2000 psig which is not something you want released in a hurry during impact. Hydrogen will ignite faster and burn in far less air that will methane or propane and when hydrogen does burn, it is invisible in daylight hours. Really great for first responders.
All that being said, to construct infrastructure in support of wide-spread hydrogen fuel consumption would have an astronomical price tag. Only governments could afford to support that.
I have yet to see what is being proposed by VW for their latest offering. I have yet to see any of the absorption/adsorption technologies become a) energy efficient, b) small enough.
What have your travels dug up in this respect?
There had always been a substantial diffusion, even through solid metal container walls. I wonder how they solved that. Or did they ?
The problem, at least then, was with car parks and garages. It collects in closed rooms, creating highly explosive mixtures.
Please let me know what you have about the success of this project!!
Oh yes.....we don't do any research & development !
Hmmm.....
A real High Point...
(begging pardon, I just had to...)

Canada does hemp best. I say more electrons for MJ, so further south the better. Get your CBD in proportion Joey & Bob, and good luck.
Buuurp...
... I'm TOTALLY allergic to CBD, it affects the SSRI uptake channels, and mine are far too sensitive. As for THC, I really am quite clucked up enough on my own as it is. Sorta like psilocyibin and me. Nothing happens (at least, nothing I don't have happen meditating on me own haunches, if you please...); I'm just *nicer* for a bit, eat some junk food, and go to bed. Well, that's what happened the last time. Why bother when it's built in...
Not sure I understood a word, and will reread.
Sitting on my haunches is apple pie, I can do that amidst the yard work all around here. However, getting back to lotus after squatting under a load seems impossible at this point... More work to do.
Psilocybin may be useful to dose if they're legit gold tops and you have a spotter. As for MonoAmineOxidase (the over-arch on serotonin, dopamine, norepinephrine metabolism) gene polymorphisms creating slow-metabolizers they're called 'berserkers'; or, "dog" soldiers, or whoever was that guy who'd put a stake in the ground and demand some-bodies come at him for a knife fight.
CBD>THC in the proportion, is likely in order for such... Maybe for everyone, regardless. Interesting bit is Anandamide as the analog, but I don't know if there is one for psilocybin that we make en"dog"enously.
Full lotus is easy, but after a load, not nice. I don't look it, but me arse does - longer in the tooth, now...
CBD's poison, THC is done - psilocybin puts me to sleep - I'm already up on that rung. Third Eye Not Blind.
I'd give a try on the dog dung - under a tight gun here. Not much breathing room.
They're in it for the free ride.
I'm in it for the gig.
Came with the first squat, the one that produced me...
