[@mycosys]

Something you didnt mention is that Aluminium is by far the most common metal in the earth's crust, lowering the cost and impact of extraction. Also adding batteries in parallel ALWAYS adds their current capability as well as capacity, what you showed was a series setup.

[@selvammatthys]

Aluminum is kind of dangerous without oxide. Don't forget they use this on solid rocket boosters.

[@jonored]

The ambri battery is calcium, though, not aluminum; it's just inspired by aluminum tech. The materials are still cheap.

[@snapicvs]

@@selvammatthys My understanding is that aluminum has to be powdered super-fine in order to be that flammable, no?

[@Isambardify]

@@snapicvs that's right. I think these would be fine as long as you didn't spray the molten aluminium into a spontaneously combusting mist. Then again being sprayed with almost any liquid metal isn't great, whether it's on fire or not.

[@Niskirin]

@@Isambardify Given that these things look like they're intended to be used in enclosed or at least fenced environments only accessible by trained personnel, I'm not least bit worried about accidents. So long as a leak doesn't cause an environmental disaster, the presumably small risk to trained personnel from their use is perfectly acceptable.

Unless I missed something, it seems like you could run the LMBs output in parallel instead of series and scale the capability that way.

[@rb9998]

Hey Joe, thanks for doing what you do. I hope you’re having a great summer

[@danielbudney7825]

Joe, the "Capability" argument needs a little closer attention. Electricity doesn't work that way. If it's just a matter of wiring two Ambri-packs in parallel ... the available Amps would double. Looked at another way: if you had one Ambri on the west end of town, and one on the east end, the two could add twice the power to the grid that a single pack could provide. So, there must be an Ambri configuration which could increase Capability.

[@akunog3665]

yeah, I love Joe, but this is bothering me. I wonder what he was actually trying to point out with this bit. Obviously there must me a configuration that would net more than 250 KW. I think he is just pointing out the available options for a single ambri pack vs a single tesla mega-pack? Like specifically Ambri doesn't manfacture/offer a single module that does more than 250 KW, if you need more than 250 KW, you need multiple Ambri packs. But this is more down to what the company is offering, and less about what's possible with a liquid metal battery. For a moment I thought there may be some quantum tunneling entanglement acting on all the Ambri packs in the universe only allowing a total of 250 KW at any one time from all of them together :D (i didn't really think this seriously, this is just what his analogy made me envision heh)

[@Qwarzz]

That must have sounded quite dubious to anyone who know anything about electricity. Adding another battery in parallel should be like adding another bottle with it's own straw. So now you can suck from two straws at once.

[@xy39]

@@akunog3665 he's cooking the argument to make Tesla look better.

[@petevenuti7355]

Yeah, but now you need x2 as many batteries

[@akunog3665]

@@xy39 yeah, he is *kinda into tesla.. wonder what his portfolio looks like.. It does look like if you have an application that needs to draw a large peak load, but doesn't need much capacity it's best to go with a tesla mega-pack, as the currently offered Ambri system would be much larger with 5 Ambri packs in series to get 1250kW, vs one tesla mega pack configured for 1200kW. But if you need the capacity anyway, it's probably smart to go with Ambri due to the durability/safety.

[@sion023]

8:23 im not sure that can be correct, connecting whatever type of batteries in parallel should always give you a extra drinking straw per coke bottle added to the chain.

[@MattOGormanSmith]

...and the KWH (as labelled) will always double with 2 batteries, no matter how they are connected.

[@starktynt4103]

Yes , i think he is speaking wrong , i don't want to believe he doesn't know what the f is he saying .

[@acorgiwithacrown467]

No he's right, replace batteries with coke because thats a stupid analogy. If they're in series the voltage should increase but amperage stays the same, if they're in parallel the amperage increases but voltage stays the same. He said the bottles were in parallel so the capacity (Amperage) would increase but the capability (Voltage) stays the same.

[@Ikbeneengeit]

7:16 this doesn't make sense. kW/hr is not a unit of energy or power. You should use kWh. Also, the cost metric favours Ambri by a factor of 3x, this isn't "tomato/tomato".

[@jamesrempel8522]

Also, at 6:59, 1000 kWh is not "1000 kW of power per hour of operation." Instead, if you could draw 1000 kW of power (probably not possible, but just suppose), then the battery would be depleted in one hour. If instead you would draw 100 kW, the battery would last 10 hours.

[@PaulLemars01]

You might want to do a video on Ferrous Iron battery. Probably less than half the performance of Lithium Iron but operates at room temp, appears to be super cheap, as heavy as blocks of iron but a major upside is it doesn't need SURFACE OF VENUS temperatures to operate. For stationary grid scale it appears to be perfect since it exploits nothing more complicated than the phase change of rust.

This is why I hope hydrogen will go big. It can incinerate human waste (no need for centralized sewer systems), pee can be used as a electrolyte.

Joe: you used to interact with the peasants here. Where you at these days? Anyway, worth reading up on series/parallel battery configuration. The Ambri batteries would be configurable for any arbitrary current output, unless I'm missing something.

[@fuba44]

8:37 they generate their own heat? Surly that heat comes from the charging current? Else where does it come from? It "generates heat" untill the battery gets cold, or the heat energy comes from the charging current aka loss.

[@hansshell6792]

It is a cycle .. once there is current flow, the heat increases, and it keeps going up, once the heating process has started, there is no need to add external power

[@lauravee9040]

I was watching some of your old videos. Iwould like to see the evolution of your bookcase

[@steeledv]

I managed a NTSC analog broadcast small Local TV Station. July 13th was the end of an era for sure. On to youtube!

[@wlittle8908]

The only battery I concern myself with is the one in my phone as I keep it charged up for Joe's Monday morning videos.

[@softyzz69]

They need to just make a gianormous Energizer Rechargeable battery and just be done with it. But then of course all you will be paying for is the name.

[@Rattus-Norvegicus]

Duracell, for the WIN!

[@Q--_--90909]

Yup

[@chriskaprys]

What a great video essay.

[@eve_avery]

Batteries with Joe again, nice

[@indie_keegan]

What about a good gaming chair as energy?: *I N F I N I T E*

Spelling of Aluminium, so it’s not aluminum.

[@klondike444]

Aluminium - British spelling.

[@keenheat3335]

is the energy cost to heat the liquid battery molten is include in the $/kwh ?

[@stuartjohnston7888]

Another beauty of LMB is that several lower temperature alloys and molten salt compounds exist that melt below the boiling point of water. So they don't necessarily have to be preheated to Venusian conditions.

[@littlehouseinthebigapple5716]

You know what was nice about this video…? Just thinking about a concept that looks towards a hopeful future…. Climate news is pretty grim this week so it’s nice to take a deep breath and hope we can science the sh!t out of this 👍🏼✊🏼

[@RCrosbyLyles]

Minor correction. Joe. Parallel is like having one mouth slurping from two straws in two separate bottles. What you described is a series connection. Batteries can run parallel to ramp up current and series to ramp up voltage. Thanks, Joe! Love your stuff.

[@ToofKilla]

The callback was gold.

[@guygillmore2970]

What is the round trip efficiency compared to other types of batteries?

[@peterpicroc6065]

Great vid again. Context, comparison with other batteries, pitching the level just right for us that consume some popular science already. Also nice pace, not as slow as manty yt'ers. Looking forward to next.

[@OttawaOldFart]

Wow you outdid yourself using an obscure reference and then having it make sense at the end :)

[@wlhgmk]

Any chance of an item on the ZnBr plating batteries (Redflow, Australia, for instance)

[@dh2032]

queston: about liquid metal batteries, so they store power like any battery do, but do they have to be heated, first before they will do anything, so do they keep the charge if they cool down, is the power charge, still usable, if thay are reheated up or is it lost for good, so could you use say coal, gas, geothermal as the heat to keep the batteries warm, would you still need to electrical add the power charge also?

[@markumbers5362]

It will be interesting how this liquid metal tech works out. It has been hyped for quite a while now. I think the flow battery from ESS in Oregon uses non toxic materials and then there is liquid air. Highview are building two liquid air, energy storage plants that will work out cheaper than Lithium, use old readily available technology and can store power for months, a bit like hydro. The race is on.

[@rynz_2893]

do they lose their charge though when they solidify?

[@deadlikedisco4726]

The beard is looking sharp, Joe. Thanks for the upload

[@Intel-6969K]

Joe, any chance you could do a video on flywheel energy storage systems? The mechanical battery!

[@andrewbreding593]

I wonder if there's any way to boost the embry batt output temporarily or permanently with better alloys or doping

[@ethanharding4470]

Joe you’re the best on KZbin

[@toddgilbert8719]

What's your take on fly wheel energy storage...

[@yunassaxer7119]

you are great!
