Todoist is great for this. Hive for bigger projects.

My company makes the world's smallest "practical" refrigerator. I say practical because you can indeed make smaller refrigerators that use thermoelectrics or other methods, but they are not useful because they are too slow to cool or don't work if the room gets slightly warm or slightly humid. For those reasons we use a phase change refrigerant like just about every other refrigerator on the planet, but the smallest one in the world.

This is the application of all the other comments in the thread. For practical reasons, like size, energy density... us engineers usually end up choosing phase change refrigerants.

Well when licenses were invented they probably couldn't just send a quick pic of the person. So color id was necessary. If that was the reason behind it, then we could eliminate any need to list race or color because everybody has cell phones now.

Agreed. Hex color codes would be a modern solution.

That's an option, I'm just seeing if we can improve upon the original reason it was put there. If it's so the Silver Alert system works, then that's pretty important, we can just decouple it from Race.

Probably for visual identification right? But I agree, race is obviously a bad solution. What if we instead assigned everyone a hexadecimal color code like in MS Paint? That would be much more effective.

That makes me wonder why we have it on the license at all? Surely there's a reason.

If it's so a medic can identify the correct medicine to give you based on your sex while you are unconscious/dying, that would be pretty important to have that correct on your license.
