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
How many here have seen the demo that used to be given by Oxy-Acetylene salesman:
Fill a toy ballon with just acetylene gas up to basketball size,
light it with an open flame,
get a modest “pop.”
Fill a toy ballon with the correct mix of both oxygen and acetylene but only up to grapefruit size,
light it with an open flame,
get a starlingly loud explosion of M80 fireworks intensity ?
