Does anyone know the true fuel efficiency that the air car has?

Did you know that you can save fuel and run your car on water
RJ questioned:
I’ve heard it has splendid fuel efficiency when it’s used with another fuel. But, I’ve heard the contrary as well. Would here be a algebraic formula to figure this out? If so how may maybe it be figured?

Roughly, in Thermodynamic, it would be the same as another similar logic:
Pressured Air as energy Storage space space for electricity. It consists austerely in a hole in a salt layer which you fill and unfilled using a compressor/turbine. The efficiency can be vaguely over 60%. That just makes the fuel cell look ridiculous.
The additional business is that is allows to start a reasonably set alight vehicle… and you don´t need the 5% energy for the AC (the gas additional room makes a cooling).
We have air cars? I want one. I don’t know of here fuel efficiany…sorry.
The potential used by a vehicle can be calculated reasonably accurately if you know 1 it’s rolling resistance 2 it’s curb mass. 3 it’s coefficient of wind resistance 4 its forward area
The formula for wind resistance is sweet hard to right out here but is plotted on this site below potential
For rolling resistance it is
Potential =gravity x mass x speed x coefficient of rolling resistance.
Just add the two collectively.
If you also calculate the potential contained in (and consumed producing) the fuel source you will be able to calculate efficiency. potential out/ potential in.
The hassle with the air car is that compressed air uses a lot of potential to yield. Compressed air potential is one of the most inefficient methods.Which tends to make it look terrible on efficiency.
It’s benefit is that it can re-compress air all owing to the braking administer which makes it far more efficient as a vehicle.(like regenerative brakes).
As with any transport overcoming wind resistance is the key to greatest improvements in efficiency.
So depending on which way you bestow it it may maybe look excellent or terrible.
