Lithium batteries scale power and capacity at the same time. Flow batteries can scale power and capacity independently.

The advantage of flow batteries is that they can have enormous capacities without the added cost of upgrading the power, making it ideal for grid scale storage.

Even if this new flow battery reaches the energy density of a lithium battery, and can output sufficient power, it would still need to reach price parity to be competitive.

Adequate for cargo flights, not happening any time soon for passenger flights. Aviation safety is very strict and slow to change.

Flow batteries are great for long duration storage, but not good for high power delivery.

This means they will work far better as grid storage than as EV batteries.

Have you ever seen what happens to a balloon that gets caught under a treadmill?

Do you want that happening to a pet?

Don't let your pets near a running treadmill.

May explode in an emergency

Could explode during normal operation

Which one is it? Should I have an emergency or not?

Do you have a source for this? I'd love to look into it further.

I have a prototype self driving system in my car. It drives logically and consistently, but it doesn't behave like a human.

This would be a really helpful feature as self driving becomes more common.

Linux Mint Debian Edition (LMDE) and Lightweight X11 Desktop Environment (LXDE) are entirely separate products.

He doesn't burn very well.

Don't tell anyone, but I actually only used 1 significant figure, so anything above 50% will do.

I'm also using the version of significant figures where I work backwards from the answer, otherwise I'd need 95% or higher and that's too difficult.

I have a spherical frictionless house in a vacuum.
