    A cubic meter is just a whole lot of volume for incredibly little power. A regular 80Ah car battery has almost 4 times the power capapcity as a cubic meter of this.

      Power density doesn’t always matter. There are applications where space is abundant, but regular maintenance is prohibitively expensive.

      In my quick example of a remote monitoring station, it may cost $10,000+ to send a helicopter out to change the 12v car battery when it dies from exposure to extreme temperatures in 5 years or less. If something like this supercapacitor can last 20+ years without every be visited, it would be more cost effective.

      You wouldn’t build a foundation with lithium batteries though. This is additional power from something that would take up this space anyway
