Be aware that an underpowered or stuck stepper motor can “skip”, causing the position data to be incorrect.
A servo motor has active feedback, so doesn’t have this issue. Servos do have their own drawbacks too, so they are not always a suitable replacement.
Prey gives you the choices up front, tells you they don’t matter, then gives you a really good game to play.
The way you play is entirely up to you, but that’s the point. Are you who you say you are? It’s easy to say whether you’ll flip a switch or push a person when you’re answering questions at a desk, but it’s suddenly much harder when you’re actually faced with the problem. What will you choose?

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.

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.
That would be a great idea, and could even help combat climate change.
What’s blue and bad for your teeth?
A really fast brick.
The current cost to drive a car with green hydrogen from electrolysis (not blue or grey hydrogen from methane reforming) is roughly equivalent to $50/L (AUD) for petrol, or $120/Gal (USD) for gas. This is one of the reasons most hydrogen today is made from fossil fuels.
A hydrogen engine is so much worse for efficiency than a hydrogen fuel cell, and even that is not good compared to batteries. I’d estimate the round trip efficiency of a hydrogen engine to be about 10-15%. So for the same energy that could be used to drive a battery EV 100km, this car from Toyota could drive 12km.
Additionally, hydrogen is not very energy dense per volume. A compressed hydrogen tank that replaces the boot/trunk of the car would have enough hydrogen for about 100km of range.
Please let me know if I’m wrong about any of these numbers. For Toyota’s sake, I really hope I’m wrong.

I use Vivaldi exclusive for the tab stacks. As soon as another browser has tab stacks (preferably more than 2 levels) I’ll switch.
I have used Kagi for several weeks and can’t go back. I can finally find things on the internet again and I don’t want to lose that again.
