You have got to be kidding about the air car. This is the best thing that could have happened to us and mother earth. We may even get fresher air.

I just love it when someone says something about this air car that knows nothing about what they are talking about. Did you know that this air car is the future and improvements and adjustments are in full swing. I love the air car and would buy one as soon as it is available. Get out of my way here I come with my air car.

You do realize that there aren't many hand pumps capable of pumping up to 4,500 PSI, don't you?

For the same reason, you aren't going to be "filling up" at the tire refill pump, as those max out about 150 psi.

What are you talking about, a pump???? There is no pump. Look into what you are talking about and educate yourself a whole lot more about the air car before you say what you are talking about.

I am with you in believing in a new and better idea then the what we have now. The air car is going to replace the gas car. Ola, !!!!!!!!!!!!!!!!!!!!!!!!! It's about time. I am all for it.

You got that right. Several years ago, when the first reports were coming out about this company, I did some calculations based on the information given, and figured out that the maximun range was achieved by tootling along at 18 miles per hour. It has to do with the engine having to take time to absorb heat from the environment to improve its efficiency. Drive fast and the efficiency plummets (until the engine freezes up!)

You've been reading nonsense. Lithium is the 33rd most common elements on earth, there is more Lithium than copper or iron, and we certainly have enough of those elements for our cars.

There are 3 problems with compressed air energy storage:
1. the volumetric energy density is very low, less than any storage battery, which means very large tanks and limited range. Increasing the pressure improves the energy density somewhat, but increases the weight and cost of the tanks.
2. There are thermodynamic energy losses involved, the higher the pressure the greater the losses. At the high pressures required, the overall efficiency is much less than for batteries.
3. When the air expands in the engine, the temperature drops considerably. While this provides "free" air conditioning, it also reduces efficiency and risks the engine freezing up in cold weather. To compensate, the engine takes in additional air while running, and the hybrid version burns a liquid fuel for additional heat and power.

@ChrisM

I believe actually, you are the one who is wrong about the lithium.

There are 92 elements that are naturally found, only eight of them are common in the rocks that make up the Earth’s outer layer, the crust. Together, these 8 elements make up more than 98% of the crust. Lithium is not one of them.

The 8 most common elements in Earth’s crust (by mass):
46.6% Oxygen (O)
27.7% Silicon (Si)
8.1% Aluminum (Al)
5.0% Iron (Fe)
3.6% Calcium (Ca)
2.8% Sodium (Na)
2.6% Potassium (K)
2.1% Magnesium (Mg)

Dave: I was wrong about the relative abundance of Iron, but Wikipedia also indicated that Lithium is the 33rd most abundant element, and "The total amount of lithium recoverable from global reserves has been estimated at 35 million tonnes". That should be more than sufficient for the entire automotive fleet, as each battery would only require a few hundred pounds at most.
