The US government knows. They just pretend not to as long as you're unimportant.
Unless the engine is super- or turbocharged, then the air is pushed into the cylinders while the sucking is left to the charger.
The magic step that eludes you is that hydrogen isn't easy to transport or store, while ammonia is.
The whole system of hardware plus running software could be viewed as a concrete implementation. "Running software" without the associated is just a series of zeros and ones that would only make sense to a particular hardware. "Software" as in source code is even less concrete; it's just a set of instructions for a compiler.
Software is complex with lots of moving parts.
Complexity is not a condition for patentability. You can have horrendously complex, but unpatentable systems.
No, software is still just a set of process steps. However, if you implement the algorithm in some kind of hardware (ASIC, whatever) in an especially clever way, then you might have something that's patentable.
Because, at the root, patents protect concrete implementations, not a sequence of process steps.
Part of the art of making a patent is figuring out how to word the claims so that copying the process becomes impossible or pointless.
And you already have the self-control of an adult. It's worse for kids, who would like to play with others, but can't because of their tendency to throw incredible tantrums (a very common autistic stress response) over seemingly little things.
Our son (diagnosed as autistic) started asking why he doesn't get invited to playdates or birthday parties, unlike his sister. I almost cried. He's starting to realize there's something "wrong" with him, that he'd like to interact with others, but can't.
Another one of these drugs is NAC (n-acetylcystein) which is sold as an OTC expectorant in some countries (not in the US for some reason):
Unfortunately, that requires a building with a high thermal inertia (e.g. lots of concrete, bricks, rocks, or some kind of thermal buffer), since heat input to the building varies with the time of the day. In a building with high thermal inertia, the AC can be sized to deal with the average heat input. In a building with low thermal inertia, the AC must be sized to deal with the maximum heat input, otherwise the building will get too hot during that time.
If it doesn't involve lasers, flamethrowers or nuclear reactors, it's not a good was to toast a cheese sandwich.
But not running continuosly.
Number two consumer of electric power: Refrigerator. HUNDREDS OF WATTS
But not running continuously, either.
Cable boxes don't come in number two and they don't consume 35 watts.
Actually, lousy designs will happily guzzle 35W of power while "off", and year-round, that's slightly over 300 kWh. That's a bit more than my refrigerator uses.
How do I know?
Your sample size is one. That doesn't give you any kind of statistical significance.
BLISS is ignorance.
