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.

Windows kept doing things I didn't want it to.
The last straw was when I had a 24 hours render running, and Windows decided to update and reboot 1 hour before it was done. I was using the computer at the time, RAM, CPU, and GPU were all at max, the mouse was being moved, I clicked "later" every time the update pop-up appeared, and it still rebooted.
Linux does what I tell it to, and doesn't do what I tell it not to do. I didn't think that was a big ask until Windows.
I've found syncthing to be easier once the initial setup has been done.
I have a 12 year old electric car with an old battery chemistry known for it's fast degradation compared to current chemistries. It still has more than 50% of its original capacity, which is still more than we need.
I wouldn't be surprised if I can keep driving it for another 5-10 years before selling the battery for grid storage.
I've worked in IT. You are most likely correct, and anyone with any sense would do it that way, but I would absolutely believe that someone could be incompetent enough to use the computer's time stamp. I also wouldn't be surprised if users had access to change the clock.
I've had an electric car since 2011. The battery looks like it will last another 10 years.
Early Nissan Leaf batteries degraded relatively quickly (8-10 years) due to poor battery chemistry and no thermal management. Both of these issues have been fixed in all new electric cars (except the new Nissan Leaf which still doesn't have battery cooling).
Even the old degraded batteries are valuable as static energy storage, and several people are using them as house batteries.
Most of the cost of a battery replacement is the manufacturer markup. There is at least one company making replacement Nissan Leaf batteries for significantly less than Nissan, and they include the latest chemistry and liquid cooling (unlike Nissan who just give you a second hand battery).
Most electric cars today have a 10 year warranty on the battery. Manufacturers wouldn't be offering that if there was a reasonable chance you would need to replace the battery in that time.
Autonomous vehicles work better on rails. Also without having to deal with pedestrians.
