HOLY SHIT ELON MUSK BTFO

What would that mean for the automotive industry? Super efficient batteries?

nigga ion een know wat that means.

finna post about corvettes vs r35s doe

So instead of 3000lbs of lithium I need to carry around 3000lbs of liquid nitrogen?

wow such future!

>>16121219
theoretically 3 times energy density/kg with approx same volume

As long as this results in elon hanging from a ceiling fan im all for it.

arent hydrogen cars still basically an electric car?

they can fuc right off m8, i need controlled explosions under my hood

>495 GPa
495 GIGAPASCALS
495,000,000,000 Pa
standard atmospheric pressure is 101,325Pa, so this is 4.8 million times atmospheric pressure

christ almighty that's some serious shit

also, don't expect it to remain metallic at warmer temps or lower pressures

hydrogen is still a meme except in fusion.

even then Helium 3 is better for fusion.

this desu

now if we were using hydrogen COMBUSTION that could be pretty cool

/sci/ has discussed this a bit. /o/tists are a bunch of mouthbreathing retards, and you aren't going to get much of a discussion here.

The thing I hate about people like Elon is how they have 0 objectivity

What I work on (lithium batteries) = best and everything is is fail (Toyota hydrogen fuel cell)

I can understand having passion for the field that you work in... But the second half is just not right...

>>16121353

Combustion engines are inefficient as fuck regardless of what you fuel them with. They're a bunch of metal scraping together, literally grinding it's self to death slowly.

Hydrogen fuel cells would almost make sense if they didn't weight so much and have shit power and range.

Shipping hydrogen is a PITA, it's pointless unless you use clean electricity to produce it which few places have.

>>16121338
they suggest otherwise in their paper

>This valuable
sample may survive warming to room temperature and the DAC could be extracted from the
cryostat for greatly enhanced observation and further study

it would be a useless phenomenon if it went back to plasma

>>16121379
what about a turbine as opposed to pistons?

>>16121389
been tried and failed a 1000 times over

>>16121260

It would be like having a big V8 in the same space as an I4

>>16121397
If gas turbines are good enough for tanks, they're good enough for me!

>room temperature superconductor

now THAT shit would be cool.

>>16121557
I dont understand the importance of a room temp super conductor.
Care to elaborate?

I know its reddit, but this thread sums it up nicely:

https://www.reddit.com/r/askscience/comments/1hp8wo/what_would_be_the_effects_of_creating_a_room/

>>16121675
Reddit aside, that shit is fascinating.
Thanks for the info, a nigga learned something today.

>>16121653
The flow of electricity creates a ton of friction. This means heat and less efficiency. We can create a near frictionless environment but it requires liquid nitrogen and similar environments so really limited on uses at the moment.

>>16121208
all i remember about the drude model is that it was right for the wrong reasons, something about multiplying one number that was an order of magnitude too small by another number that was an order of magnitude too big.

also do you people realize how fuckhuge 495 GPa is. that's a million times more pressure than the normal atmosphere.

>>16121370
hydrogen fuel cells are full of fail though.

Toyota is going to make a battery EV version of the Mirai. Just to recoup the expense of developing a $60k corolla with special fuel.

>>16121379
>Combustion engines are inefficient

doesn't matter since currently nothing comes close to the energy density of gasoline

>>16122729
uhhh what is DIESEL?

>>16122729
uranium would like a fission with you

>>16122813
thats real punny

>>16122880
Glad I enriched your day

>>16121208
ehhe xd

>>16121457
It's like the rotary of batteries

>>16124809
so it'll be an unreliable battery that's powered by doritos and eats oil?

>this will ever be practically achievable for consumer use.
Next thread

>>16124821
Thanks for keeping prices down with your lack of knowledge! FUCK I'm so thankful people like you exist or the FD would be 40k

>>16121389
Turbine works but has poor emissions

>>16125462
This lol
Prices on FD in my area are gutter cheap because all the underage buy rice and all the boomers buy pigfat

>>16125473
>>16121389
turbines get less efficient the smaller they get, in a non linear fashion.

>>16122790
horrible emissions.

modern diesels aren't the long lasting low maintenance machines they used to be.

>>16121326
hydrogen fuel cell cars are hybrids, technically.

since they have to have a battery pack for regen and to store energy made by the fuel cells.
