Batteries, with lithium-based formulations, have reached peak energy density while still being able to remain safe and functional. Rechargeable batteries contain only tiny fractions of the energy density of chemical energy stored in hydrogen, fossil fuels, and even wood.
Thus, it becomes clear that to increase mobile energy density, we must utilize chemical reactions in our energy sources. Is hydrogen the answer? Can we create reliably "rechargeable" hydrogen cells with reactors at least small enough for a laptop? Discuss.
>pic related is not a great example, but perhaps the only example at this time
>the batteries ... will have an energy density of 1,000 Wh/kg (for comparison, lithium batteries generally have a energy density of 180 Wh/kg) >hydrogen energy density is 33,300 Wh/kg
Right. so the absolute best in the field is still an insignificant fraction of the energy stored in hydrogen. Even fossil fuels hold 12 times as much, but obviously fossil fuels aren't remotely suitable for mobile applications.

Lithium-air batteries. God knows how far away we are from them though, I don't think they've even been made in labs.

it's not

What if we go full dieselpunk and put ICE in our phones?

Mass seems to be misleading here. I can only imagine how fucking big one litre of Carbon would be.
Julian Ross
hydrogen isn't eco-friendly
Isaiah Hill
Utilizing hydrogen is much harder in small form factor and it produces lots of heat.
Logan Clark
It can be; you can use multiple types of renewing energy for electrolysis.
The charger in pic related is too weak to charge anything from this decade
Wyatt Harris
You're dumb as fuck and really have no idea how any of these systems work. Take your scientific illiteracy elsewhere.
Logan Walker
The cells in picture are actually in much less volatile powder form. They burn much less violently however produce less power as a result.
Christian Anderson
So instead of giving the thread something useful, like correcting the statement and enlightening us all you decided to come here telling how much better you are.
Aaron King
Hydrogen fucks the ozone layer.
Jordan Sullivan
did they just glue a bolt to the top of an 18650, paint hydrogen on the side, and make bank off of numales?
Connor Clark
> muh hydrogen
hydrogen is fucking awful for portable batteries even before you worry about the structure of the fuel cell itself.
pic extremely related.

If poorly contained and released in massive amounts sure, but these kinds of solutions often come in powdery form and are burned very clean.

booze powered fuel cells when?

Fuck you you smug fucking cunt. You came in and made a dog shit thread that you knew was wrong and are acting like you're not the one to blame. Fucking kill yourself.

litre is a measure of volume so it would be exactly the same size as a litre of water. it would weigh a fraction of a gram though.
Luis Garcia
>Smug cunt Ironic considering how you've been basking in your own glory since coming here.
I'm actually enother guy, however i find confusing that you bash others for not knowing things but refuse to actually point out whats wrong and how it should be instead. Not that you'd care, you're only here to argue with people.

Yes, outside the fab where I work we have massive tanks of the shit which get moved to a compressor. The silly Mexican gardeners always smoke around them and get fucking screamed at by the engineers. We gonna blow up one of these days.

>I can only imagine how fucking big one litre of Carbon would be. This is a joke right? It would be a liter. How dense are you?
Jace Russell
Guarantee you can't point out a single example that anyone other than your hyper-autistic self would consider "basking in your own glory"... because only a fedora-wearing dipshit would even think something like that.

Unless you have the secret to making stable metallic hydrogen at 25*C and 1bar of pressure somewhere up your ass user; comparing this is a fools game.
Just increase energy efficiency. Same effect and far more viable.

Wood Gasifier creates flammable wood gas. Wood gas burned to power flame licker engine. Flame licker engine drives dynamo. Dynamo charges phone.

Thermodynamic oil collapse is inevitable, you have until the year 2033 before complete collapse, periphery areas(third world) will begin collapsing first, Venezuela is already in collapse, Saudi Arabia is on verge of collapse
