which of the assertions you made are your original thoughts, theories, or ideas?

How in the hell did you graduate high school without an even rudimentary understanding of physics?

Or did you even graduate HS?

Ok, kids...the trolling festivities and lawn beer can empties is over.

You'll just have to rely on the usual 2x day method -- your imagination and nightstand paraphernalia.

It's not trolling when you don't engage and simply deride something so dumb.

Live look at Liberator strolling through his neighborhood:

Have one in the bookcase that my grandmother bought decades ago.

Once upon a time Baton Rouge ( like many places) had streetcars. Most generally, streetcar companies where owned or operated by the an electric company.

They were under contract to provide their service for about 5¢ a passenger ( i think) and had to do ALL of the upkeep of the roads they used, even though other cars and trucks used the same roads, with increasing numbers every year.

They were not allowed to charge more. In New Orleans, this eventually led to the streetcar drivers protesting and striking. Legend has it that the PoBoy was created as a cheap meal for these "poor boys" who had little income during this time.

Meanwhile in Baton Rouge in the 1930s, the streetcar line was switching to buses because of this. It was cheaper to switch to buses and so they did. The streetcars were all disposed and destroyed. By 1934, the last streetcar ran in Baton Rouge, never to be seen again.

Not to argue but the OT has a point. We know there is a 100 year light bulb, I remember Goodyear buying the patent for no wear rubber in the 80s promising longer lasting years, the germans allegedly developed a synthetic gas formula at the end of WW2, etc etc. if someone has a cure for cancer I am sure they would be murdered or be bought out by big pharma. Hell they discovered cure for mot all ulcers 20 years ago and I bet barely anyone on her has ever had it, abs they tried to bury that guy

I decided to do some calculation on our compressed air power car.

I used a pressure vessel with 1 cubic meter of volume.
Ambient temp at 80 degrees
The initial pressure in the vessel at 1,000 psi

In isothermic expansion, this gives 30,000kJ of energy.

30,000 kJ of energy is 8.3 kWh is enough energy for a Telas Model 3 to go ~38 miles in ideal conditions

30,000 kj is roughly the energy in 1/4 of a gallon of gasoline. The highest milage gas (non-hybrid) is a 39 mpg combined.

Basically, you need a LARGE pressure vessel and/or very high PSI to begin to have a "normal" range for a car.

One important thing to note is air compressors are VERY inefficient roughly 10% for the better ones but far less for super high pressures like 1,000 PSI and above. So in the hypothetical car if you use a baseline of the model 3 and the air engine being 100% efficient it would go 38 miles BUT you would have to use 300,000 kJ of energy to accomplish this assuming an incredibly efficient compressor capable of 1,000psi (10% efficiency). That would be 83 kWH of energy used to get a car to go 38 miles.


TLDR compressed air cars would be incredibly inefficient and if you can build an air compressor that approaches 20% efficiency you have a multi-billion dollar idea.
