Should current battery cells be improved or should we move to

If you dig the stuff for batteries out of the ground to start with why can't you just chuck it back into the ground once you're done with it?
If you dig a ton of stuff out of the ground and eat it you'll die whether it's toxic waste or regular ore. There's functionally no difference.

>hydrogen fuel cells
yes
and electrolysis to get hydrogen from sea water with electricity from deep geothermal

boom worlds energy and pollution problem fixed

Whoa, you must be like a genius, or something! :^)

wow great thread

The total entropy of the universe will go up if we use hydrogen fuel cells.

>>9068349
It'll go up no matter what. The universe is destined to die by design.

>>9068417
>by design.
Oh shit!
Hello God!
Fuck off faggot, stop playing Nostradamus.

tens of trillions of infrastructure spending needed.

>>you can drive a typical mercedes E-class for eight years before you do as much damage to the environment as a Tesla
Sounds like you pulled that right out of your ass

Car batteries can be downcycled for grid level energy storage. They may not have enough charge to drive a car 100 miles, but they might still have enough to drive it 80, which would work just fine for grid level storage.

Yes
>Should we move to hydrogen fuel cells
Not yet

Battery technology is still not at it's full potential, mostly because of chemical problems, like the formation of Dendrites in the electeolyte, and the problems with narrow temperature ranges. Or out of "room twmperature" spectrum.

Srill, there are a LOT of different teams working on this issues as we speak, about 6 months ago, there have been lots of imñrovements, but we are still missing the holy grail. Oh and also Metal-air batteries have amazing potential.

Look for UTexas and Dr. goodenough for the improvements on Lithium batteries


And for the Hydrogen cells, I Mean rhwy are cool and all, but the ways we have to make hydrogen are pretty inefficient. Untill we. Have a more reliably method, we're stuck.

Plus Hydrogen is just a middle man, If batteries were more efficient they would make Hydrogen a niusance.

>Tens of trillions
Distributed for each region's energy needs, one person isn't paying for all of it. So if the only downside is start up cost what's the problem?

>>9068485
the economic stimulus would pay for the costs
just imagine how much extra spending money households will have when electricity/water/fuel becomes effectively free

>>9067978
Technically it is IMPOSSIBLE to go to battery solution. There are not enough of the raw materials being mined. Cobalt for example.

>one of the most combustible and hard to store materials
>making it the base of the energy
We stopped using dirigibles partially because of it. Fuel cells are all right, but using other fuels.

cool, thanks

>hydrogen fuel cells

Research in those areas died a decade ago. They proved to be inferior.

The new thing is solid state batteries.

>>9071203
great, that was really cool

>>9069212
Hey same thing could be said about Tungsten, and yet here we are and the chinese have it all and are rising the market prices. There is enough for a good amount of batteries, just that is so delocalized that it's hard to grasp

>>9067978
Hydrogen needs 2-3 times the amount of elctricity that an electric car needs.
Either way, as it looks, solid state batteries are around the corner anyway. Samsung said they're gonna make smartphones with them in a year or two.

>>9069115
are you drunk?

>>9068419
Its the second law of thermodynamics you brainlet. Entropy always increases. Even if the universe doesnt have an "end" eventually there will be no useful energy left.

>>9073415
Not yet, I'm just a dumb phoneposter that loathes autocorrect

>>9073650
my condolences

>>9068333
I think we'd be better off with biodiesel no electricity required just the sun.

>>9073619
maybe energy is being created somewhere and pumped into the universe
