It sure looks interesting, more information here:

If I did the math correctly it seems like it's in the 120-140 wh/kg range.
Certainly usable for EVs.
Hopefully it makes it out of the lab.

Indeed...I just checked the abstract and it cites 70 mAh/g. It's an unfair
comparison because of all the extra hardware from the box and what-not, but a
CALB 180 Ah battery weighs 5.6 kg, which works out to 32 mAh/g. That they're in
the same order of magnitude tells me this may well be

You can't compare Watts/kg with Watt-hours/kg. That's like comparing
horsepower to gallons.

David,
Typical aluminum-air cells have a power density of around 60-70 W/kg, so
40 W/kg didn't seem out of line. To the contrary, it's the 3000 W/kg number
that seems awfully high.
