How much does 1 gallon of gasoline displace as a vapor? The saturated vapor volume of an average gallon of liquid gasoline when fully evaporated is 160 gallons of vapor at 60° F and sea level.How an ultrasonic
nebulizer works to convert a liquid to gas.
Using an ultrasonic nebulizer, liquids in a vessel (such as a fuel tank) sit on top of a vibrating element. and a high intensity ultrasound is omitted. As waves move through the liquid, the liquid will begin to be pushed upward, making a small fountain. Off the surface of this fountain small particles will begin to float above the liquid and appear like smoke. This smoke like appearance is actually very fine vapor. If gasoline was used in this process the small particles that would appear like smoke would be very fine gas vapor. To move the very fine particles a small air flow/gas or vacuum is needed – like a small fuel pump or the vacuum that exists in all combustion engines.Is the ultrasonic nebulizer technology to convert liquid gasoline into a more abundant (160 times more) vapor gas safe to use? A fog machine reveals that it is safe as a fog machine is a device which emits a dense vapour that appears similar to fog. This artificial fog is most commonly used in professional entertainment applications. Typically, fog is created by vapourizing proprietary water and glycol-based or glycerine-based fluids or through the atomization of mineral oil. Mineral oil is liquid petroleum which is a liquid by-product of the distillation of petroleum to produce gasoline and other petroleum based products from crude oil. If a fog machine can safely and effectively atomize mineral oil – a by-product of oil – then a similar device like an ultrasonic nebulizer can also safely and effectively atomize 1 gallon of gasoline to produce 160 gallons of gasoline vapor.
When you burn gasoline under ideal conditions, with plenty of oxygen, you get carbon dioxide (from the carbon atoms in gasoline), water (from the hydrogen atoms) and lots of heat. A gallon of gasoline contains about 132x106 joules of energy, which is equivalent to 125,000 BTU or 36,650 watt-hours:
* If you took a 1,500-watt space heater and left it on full blast for a full 24-hour day, that's about how much heat is in a gallon of gas.
* If it were possible for human beings to digest gasoline, a gallon would contain about 31,000 food calories -- the energy in a gallon of gasoline is equivalent to the energy in about 110 McDonalds hamburgers!
We will assume our car weighs 1000 kilograms (2200 pounds).
What Can You Do With a Gallon of Gas?
To raise an object, the energy needed is mgh, where h is the mass of the object, g is the acceleration of gravity (9.8 meters per second squared) and h is the height.
To raise a car weighing 1000 kilograms a distance of 100 meters would require about a million joules. You could raise a car 12.5 kilometers with the energy in a gallon of gas, or drive up 125 100-meter hills. Driving up Pike's Peak (about a 3000-meter climb) should consume about a quart of gas.
But these figures assume you can get all the energy out of a gallon of gas and apply it with perfect efficiency to raising the car. Driving miles of winding road up Pike's Peak is a far cry from simply lifting the car vertically.
It takes energy to accelerate. The energy of a moving object, called kinetic energy, is given by K=1/2mv2, where m is the mass of the object and v is the speed. If a car weighs 1000 kg and accelerates to 60 mph (27 m/sec), the energy required is 365,000 joules. About 350 such accelerations would consume a gallon of gas, assuming you could apply all that energy solely to accelerating the car, which you can't.
Just for fun, in outer space, if you could apply all the energy in a gallon of gas to moving a car with perfect efficiency, you could get 125 million joules = 1/2mv2, and for a 1000-kilogram car you'd have v2 = 250,000 and v = 500 meters per second or 1120 miles per hour.
If we could get all the energy out of a gallon of gasoline and apply it to overcoming the rolling resistance of a car, we could get about 400 miles per gallon. But the internal engine resistance multiplies the force required by roughly five, meaning the best we could hope for is about 80 miles a gallon. The engineering constraints of getting useful work out of expanding hot gases cuts that figure by 50 per cent to about 40 miles per gallon. So better fuels and fuel injection could improve mileage, but not stupendously.

Our current car technology is stiffled. The Government NEEDS mass amounts of crude oil being bought by you to keep shipping/air travel/food affordable.
If we built a car today that got 100mpg.......gas prices would skyrocket. Our military would get less fuel to sail ships due to costs...that's the real bottom line.
