The same of the oil car and more.
The air is 79 % nitrogen, 20 % oxygen and 1 % others gases.
When we get the oxygen from the air for medical and industrial applications, we need to separate the oxygen from the nitrogen , to do that we need to cool the air at -170 celcius, and the air become liquid.
Then we let the air warm up and the oxygen become gas before nitrogen.
After that, we have liquid nitrogen that is an industrial waste.
One liter of liquid nitrogen becomes 696 liters of nitrogen at atmosphere pressure and temperature.
The Boyle Law of the gases said that, in a gas, the gas pressure x volume is constant if the mass and the temperature of the gas is the same.
For this law if we put in a tank a liter of liquid nitrogen and we wait that the nitrogen warm up to the atmosphere temperature the pressure in the tank is 696 Kg/cm or 696 X 14.2 = 9883 PSI and the energy is 38605 kilogrameters. We need to use the gas at this pressure that only with my engine is possible, if we want to get all the energy, in the first car of the UNT they expand at 10 kilos and only get the 8% of the energy.
The price of the liquid nitrogen is cheaper than the compressed air but if we use a lot of vehicles with liquid nitrogen it becomes more expensive because is no more a waste.
The liquid nitrogen vehicle has less power than the compressed air because you need to wait that the nitrogen reach atmosphere temperature.
In a liquid nitrogen vehicle you need to put heat exchanger.
Yes. In this moment are running in the world 1 million of vehicle with Compressed Natural Gas and never have problems because the tank are made with carbon fiber and in case of an accident they only leake. We are going to use the air at the same pressure 3000 PSI and the air don' get on fire like the Natural Gas. If you have an accident on an oil car and in the accident the door broke and you cannot go outside and if the car get on fire you are in a very bad situation.
Just in USA, 3000 people die every year in these kind of accidents, this never is going to happen if you drive an air car.
If the tanks work at 3000 PSI maximum pressure they will be test at 7000 PSI .
In 1959 I got the idea of the compressed air vehicles and I started to work alone in 1984, but in 1997 I got the information that between 1900 and 1910, in Paris, New York and London there were train engines running with compressed air.
This locomotive run at low pressure 500 PSI with bad efficiency, with a big tank it run 20 miles range.
In 1997 after I be back of USA, I was in Uruguay and I read in a magazine about the car of Guy Negre, was a car that run with compressed air and gasoline, afterward use only compressed air but in the draws of the engine they keep the combustion chamber I don’t know why.
The engine of Guy Negre have two pistons, with the first piston he compress the air of the atmosphere and use energy for do that, the air become hot, but you need energy to heat the air when you compress the air. This energy come from the second piston.
The idea is that the air that expand don't become cold but the best way is to get that with a heat exchanger after the air is hot you can’t do that, and you can’t get the energy from the atmosphere.
After the air is compress go to the combustion little chamber, and there put the air from the tanks, afterward the air go to a bigger piston where it work.
The problem is that only use the difference of volume of the two pistons.
When the air go to the chamber the air is decompress and you lose energy, that is one of the reason why this engine have less than half of the energy of my engine.
In technical description I explain all the problems that have the engine with crankshaft for example that the piston is moving when the air go inside the cylinder in the Guy Negre engine move slowly when the air go inside the cylinder but is moving.
In 7/25/04 looking the web page of Guy Negre I saw a engine that is motor and compressor for a car, I have the same patent in Uruguay and Argentina. Urugayan patent number 22976 date 9/11/1989 and Argentina patent number 317786 date 9/6/1990 the name of the patent is Motor Compresor de gas de eficiencia total.
Is very cheap, I did the car that run 100 kilometers in Maldonado in 1992 with only one charge of air in its tanks with a pipe of PVC with fiber glass out side,4 bike freewheels and 4 bike chains. You can do this engine with only a lathe and a welding machine.
The tank keeps the energy forever. In a batteries car, in one year if you don't use it you lose the energy and the batteries too, in a nitrogen car you lose all the energy.
We are going to have several trucks with big tanks of compressed air, and you can call and have the recharge service of compressed air in one minute after they reach you, or you can stop another car with compressed air and get the air.
In our stations you can get the energy in one minute.
Units: International system M.K.S. Distance meter=M Mass kilo=k Time second=S
One Km is 1000 meters.
Force: kilo force is the force that the earth does to a kilo mass.
Energy distance time force E= D x F
E=kilogrameter=kgm is the force of one kilo in one meter distance.
Example; For move a VW at less than 10 kilometers in an hour we need 10 kilos force and for move it 100 kilometers we need 1000000 kgm because the force is 10 and the distance is 100000 meters 10 x 100000=1000000
One KWH is 366972 Kgm of energy.
The Boyle law is pressure time volume is constant
P X V = K
The atmosphere pressure is near one kilo in each cm square.
If we put 10 liters of air in a liter tank we have 10 k/cm pressure.
When we decompress a gas we lose energy.
Example: We have a tank with 40 liters at 3000 PSI 3000/14.2=211.26 k/cm the energy of one liters at 211 K/cm is 9245 Kgm the energy of the tank is 40x9245=369838 Kgm if we decompress to 21.1 K/cm we 10 times less pressure and ten time more volume the energy at 21.1K/cm is 473.1 Kgm and the energy that we have now is 400x473.1=189249 Kgm we have only 189249/369838x100=51% of the energy.
