Reality check on electric cars

[Into the Night]

Poor Into the Night. He thinks that OSHA required paperwork is chemistry.

LIF. Grow up.

The funny thing is I don't recall when the Japan, South Korea, Mexico or Canada became part of the US. The chips are imported and a tariff would increase the cost for the chips made outside the US.

Tariffs are not place on all countries on all products, Poorboy. Compositional error fallacy.

 

[Into the Night]

You are wrong yet once again.

See the 1st law of thermodynamics.

Mimicry. Grow up.

 

[Into the Night]

It's not a great solution. This is related to what I worked on about 25 years ago in my second postdoc. Solid storage for H2 via metal hydrides is limited and small for the weight of the metal hydride. We were looking at other solid storage solutions and they didn't work out.

Hydrogen is not a metal. Hydride is not a chemical nor a metal. Stop pretending to be a chemist.

No I'm not. Nothing of the sort. I understand that nuclear is probably our best solution to decarbonizing our energy infrastructure.

Carbon isn't an infrastructure. It is a fuel.

 

[Into the Night]

Yeah. The US still has a lot of active fabs

Very little.

so we already have some infrastructure and DURING THE HORRIBLE BIDEN ADMINISTRATION we got the CHIPS act which will encourage MORE domestic chip production.

It doesn't.

But right now so much is made outside the US that this weird "tariffs on everything" approach will do NOTHING but increase prices for everything.

There is no 'tariffs on everything'. You are hallucinating again.

I can't wait to see the MAGA voters tell me how paying EVEN MORE THAN THEY ARE NOW is a "good" thing.

MAGA isn't a person.
Tariffs are not inflation.

Any gas at 10,000 PSI will do that. Add in the potential explosion and it's too much.

I don't think any 10,000 PSI pressures should be in everyday equipment, at least not until we have some of those super materials like carbon nanotube tensile reinforcement.

Yeah. Hydrogen and carbon under 10,000psi. THAT's gonna work!

It's obviously a lot safer with a metal tank where the alloy doesn't do brittle failure, then failures manifest as holes instead of explosions. BUT metal is too heavy and does a poor job containing protons so last I checked they were using composite tanks for hyperpressure hydrogen storage on vehicles.

Hydrogen is stored in metal tanks as a matter of routine, Pretender.

I never said it wouldn't work, I'm saying that in the long term on the global scale solving the problem of mass producing propane is the cheaper and safer solution.

No, gasoline is.

Obviously if liquid hydrogen were to work it would require a self-contained refrigeration system combined with some very effective insulation techniques (double mirror vacuum layer and such).

Do you have any idea of how much energy it takes to liquify hydrogen??

Again, didn't say it was easy; but making 10,000 PSI safe isn't easy either. It's a question of what difficult effort ends in a safe scalable solution.

Do you have any idea how much energy it takes to compress a gas to 10,000 psi??

i.e. when I said "propane" I meant burning propane in some kind of combustion engine be it pistons or a turbine.

Energy density is too low. Better to use gasoline or kerosene or diesel oil.

However when we're talking about storing hydrogen it would be more efficient to use that in a fuel cell rather than burning it?

Energy density if too low. Better to use gasoline or kerosene or diesel oil.

I did mention space

Do you have any idea how much energy it takes to get to space?? What are you going to mine when you get there??

Once the ball starts rolling it wouldn't be that much different from mining anywhere else. In forty years the most menial human labor outside of service industries will be piloting a drone. The actual staff on site could be very small; like a hundred people for an operation that supplies the whole planet.

Space is not a planet.

Space is not a planet.

Yea... time for the ignore.

 

[Into the Night]

Yea... time for the ignore.

Argument of the Stick fallacy.

 

[Kafka]

Well that is unfortunate. I thought fuel cells are more efficient than practical combustion engine can be right?

Don't get me wrong. They are a great thing. I have no problem with a FC car but it is hampered by storage or generation of the H2 fuel.

If so that would be a pro in the "store hydrogen" column, something to balance out the challanges.

I haven't been active in the field for a very long time. I haven't heard any major breakthroughs. I'm sure carbon is still being investigated and maybe more exotic metal hydrides. I wish I knew.

I mean when the concentration is low it sometimes makes sense not to try to find the maximum concentration of that mineral but to look for the intersection of several useful minerals in a formation.

Ahhh, sorry. Yeah. I know what you are saying. You are 100% correct. These minerals while having some degree of concentration over the usual sort of "background levels" are still a lot lower "grade" that a big ol' 6' thick seam of coal.

The lower concentration output is "a byproduct". Or you could consider the higher concentration a byproduct but that sounds wrong. Point is you get both at the same time and that saves a lot effort and environmental damage.

We don't have a great history of mining anything cleanly.

It isn't and it worrisome that you think it's absurd without thinking about it.

You're not one of those Gaia worshiper types are you?

No. Just have a doctorate in geology.

Going through less rock has got to be cleaner on average. I have a feeling a lot of useful stuff gets dumped in a big pile because the energy costs of further refining are prohibitive. For uranium that's chicken out of the egg, if we were allowed to build some serious fission reactors the uranium would pay for its own refinement from tailings that are being discarded now.

That's the sea around the continent. That's like saying an open pit mine in one of the isolated rocky mountain watersheds is going to be a problem for San Francisco Bay.

Quoting from the abstract:

in the entire continental Antarctic the vegetation is desert-like, composed of scattered mosses, lichens, and terrestrial algae. Exposed surfaces of crystalline rocks harbor “endolithic microbial life,” and a few species of invertebrates dwell on favorably exposed soil and under rocks. The ice Plateau is as nearly abiotic or sterile as any area on the earth's surface.

It's dead, I knew it was dead; it's still weird that you were sure it wasn't dead.

No. Just have a doctorate in geology.

Geology below five meter depth doesn't have an ecosystem.
