Come with me if you want to squeeze dem titties

"So, this other guy, he's a Terminator like you, right?"

"NAHT LIKE MEH. A TEE-WUN-TOWSAND. IDVAHNCED PROHTOHTYPE."

"You mean more advanced than you are?"

"YEZ. AH MIHMETIK POLEEALLOY."

"What the hell does that mean?"

This is a step.

It looks like this is for high voltage utility applications.
They are taking 2 cheap metals + salt as a dialectric.
It is being kept at 700 deg. C, tho. That seems like the unsafe part.

That's not so outlandish a temperature for industrial vessels, refineries and chemical plants keep large amounts of molten sodium or sulfur around for reagents. Also, as the article said, some of the materials handling technology could be taken directly from aluminum smelters.

Go faster! Go faster!
Put your foot down on the petal!
He's gaining on us quickly
and he's made of liquid metal!

Prof. Sadoway is one of the most baller scientists you will ever meet.

Okay, for this thread I'm going to be That Guy. The "finding Sarah Conner" theme is ready for its gold watch and retirement party.

Come on, Farkers. You're the team that came up with "It's A Trap", the "Ha Ha!" guy, and "it's always c)". We've got something better waiting in the wings than another reference to a 17-year old action movie.

Get Out!

It can't be retired yet, they have yet to perfect the spelling of "Connor"

1) Nasty on the consumer level but not a big deal where it's only going to be dealt with by professionals and where it can be sufficiently isolated.

2) Personally, I find ultra capacitors scary. If something damages one so as to short it the energy is going to rapidly dump through the short. Some years ago I worked out that the energy in your gas tank (typical car, full tank) is about that of 500 pounds of TNT. That's more than a 2000# bomb has. (Bomb weight refers to the whole thing, not just the explosives.) What happens when you have a traffic jam and an accident manages to breach one capacitor?

I'm sorry John, add-ons is closed. You'll have to call back tomorrow.

I'll see your theoretical thesis-machine and raise you an actual technology that doesn't need to run at 700C... (new window)

The whole device is kept at a high temperature, around 700 degrees Celsius, so that the layers remain molten. In the small devices being tested in the lab, maintaining this temperature requires an outside heater, but Sadoway says that in the full-scale version, the electrical current being pumped into, or out of, the battery will be sufficient to maintain that temperature without any outside heat source.

Thank you. Logic restored, civilization saved.

Well that's where your ultra capacitor needs an addition in order to handle flux. Luckily that was already invented back in 1955.

Redox batteries still have that low power to weight ratio. Here's a very old battery technology used in many satellites that may offer a low cost, high energy density alternative to lithium ion. Ceramatec's layered ceramic battery technology also looks quite promising, as it runs somewhere around 98 degrees and has energy density above and beyond any lithium derivative. However it sounds suspiciously similar to ultracaps.

Finally, I'd like to point out that even the tried and true (but low energy density) supercapacitor is sufficient for some EV applications. For instance, a network of buses powered by supercaps is currently in operation in Shanghai. They get 20 miles to the charge, but every stop has a short stretch of overhead wiring (like a six foot segment of the overhead wiring you see along streetcar lines) that the supercaps can fully recharge off of in 3-5 minutes. As the stops are rarely anywhere near 20 miles apart the actual recharge time would be less than a minute in practice.

I was curious when we start docking people for that.

The picture in the article looks like they're making ice cream.

\for the celebration?

Cheap and scalable enough to hold utility level amounts of power has fark all to do with any existing battery technologies that are aimed at powering mobile devices.
Comparing this to existing, or worse yet, in development batteries that would go in laptops or electric cars is missing the point.

If this is as cheap to build and maintain as implied (vastly cheaper than anything we have now) it will change the economics of power production, especially the amount of variable output renewable sources that can be used but also things like peak capacity.

Without specific information regarding cost, efficiency of storage and scalability both up and down it is difficult to speculate what the range of applications will be but it sounds like it should be incredible.

Article mentions the battery being able to heat itself through insane operating currents (tens of thousands of amps). It was the first drawback I saw with the idea: okay, so you have to superheat the thing to keep it active, where's THAT energy coming from? That's greater than fault level current, which suggests that these devices would operate at lower voltages that would need to be stepped up significantly to feed the grid.

This could solve a lot of problems associated with renewable energy nonlinearity on the grid. Store what is captured and convert it into a constant source.

My logic bullshiat detectors are going off. What if the wind isn't blowing or the sun isn't shining to keep it hot? Do we keep them hot with coal fired electricity?

/Back to square one.

That energy is being generated at steel/aluminum making facilities regardless of renewable sources. So, initially this seems like a more feasible form of cogeneration for these types of manufacturers.
