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.

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.

Most engines are less than 30% efficient at producing movement. The majority of the energy is lost as heat.

Thermodynamics tells us that pretty much all energy ends up as heat. In a closed system, any device that uses energy is 100% efficient at making heat. A 1000W computer will make exactly as much heat as a 1000W heater.

A 100% efficient engine can only exist if the desired output is heat, thus making it a pretty useless engine. Also, in a closed system, the exhaust cannot leave.

Mint is based on Ubuntu, which is based on Debian. LMDE is being built alongside Linux Mint and is based only on Debian.

Linux Mint and LMDE are functionally the same, but LMDE is protection/insurance against Ubuntu doing something stupid.

A timeline of Rock Paper Scissors

I highly recommend Linux Mint (cinnamon) as an entry level Linux distro. It looks and feels similar to Windows, and it's based on Ubuntu, so it has a lot of support and compatibility.

That would be a great idea, and could even help combat climate change.

Why limit these fees to foreigners? Why not penalize anyone who is leaving properties empty?

Space Oddity

An Arabic digit is a number.

You might be numb, but you could always be an Arabic digit.

It depends on your country, your budget, your definition of good, and your driving needs.

A second hand Nissan Leaf or Chevy Bolt are more affordable, but don't suit everyone's needs.
An MG4 is a great budget new car, but can be out of some people's price range.
A Polestar 2 is a comfortable option from a manufacturer who cares about the environment.
A Porsche Taycan is a performance car for a fraction of the price of a petrol supercar.
