Why is Ammonia as a fuel never brought up?

120 octane
$0.85 per gallon
It can be made from air and water.
It's less flammable than gasoline or hydrogen.
It can be stored at higher temperatures or lower pressures than hydrogen.
Emissions would be nitrogen and water vapor.
It can be mixed with gasoline or diesel.
Most newer engines can run on 10% without modification and up to around 80% with few modifications.

Here's what windmills are good for. Shade.

Ammonia can kill you. I used to help a commercial refrigeration company years ago. Ammonia will go straight to moisture such as your eyes or lungs. A major vapor leak can clear a production facility quite quickly!

Gee, we could just use fusion power to generate the hydrogen, should be ready in sometime in the next 30 years, which they have been saying for the late 50+ years.

IOW, don't count your chickens till the egg hatches.

Right on cue,
Greenies say Hydrogen future would make Methane worse...

We should keep in mind that Hydrogen “embrittles” many metals and cause failures through cracking.

We should also keep in mind that today’s “Snowflake” college engineering students do not have to take a required “Failure Analysis” class their senior year.

We should also keep in mind that the lowest grade that an engineering student can get is a B rather than an F.

Give a university science student a B+ rather than an well deserved F and it is highly probable that the student’s parent will call both the class instructor and University Vice President and threaten a lawsuit.

Got it. Hydrogen could be bad if leakage occurs on a large scale. Yeah, I wonder what other fuels would be bad if they leaked on a large scale.

Which reminds me, I remember 15-20 years ago hearing no one would want a car with a tank full of hydrogen given how explosive it is. Because what, gasoline is not explosive? Hello Ford Pinto

Wasn't there something called a hydrogen bomb?

There are 3.785 L in one gallon. Assume that the molecular formula for gasoline is C6H14 and that the density of gasoline is approximately 0.85 grams/mL. There are 4.50 x 1026 atoms in 1 gallon of gasoline.[/quote]

What's the count now for states that are banning gasoline powered vehicles by 2035, think it's approaching about half the states. Bye, bye ICE.

That 4.5 x 1026 can’t be right, must be a whole lot of zeros missing

As luck would have it,
“13 lucky miles away as the crow flies”
from where the acetylene/oxygen gas in the toy ballon was ignited
there were Thermo-nuclear Hydrogen bombs in storage
plus three varieties of nerve gases in aerial bombs, artillery shells, and mortar bombs.

“There must have been quite high security guarding those”
you might think.

In another odd accident a few years later,
I was present when when the US Army Colonel in charge of that storage area
was told by a Railroad employee that the security gate where the railroad entered the storage area
had been crashed into and destroyed 6 days earlier
by sole fault of the railroad crew, and the railroad was willing to totally pay for its replacement.

The Colonel got a weird look on his face and turned around and picked up a notebook,
turned pages looking at entries,
asked the railroad employee again:
what date and time did this gate get destroyed?

The Army guards had been too lazy to walk down and carry out their duty to inspect that gate.

Years later a special plant was built to chemically neutralize the nerve gas filled weapons.
Pipe welds in that plant were to be 100% x-rayed.
The x-rays that showed defective welds were faked to show good welds.
All the welds had to be ground out and re-done at great time delay and expense.

Ignorance is bliss.
It probably is even worse than you suspect.
