The fuel is air compressed to 4, 350 pounds per square inch, or 300 times the pressure of the air you breathe.
Instead of sparking the ignition when the piston is close to top dead center (when the air is compressed), that spark occurs as the piston is pulling away, when the air pressure is at its most turbulent, creating much faster ignition and more power.
Now we have Frenchman Guy Negre and his Aircar, whose fuel is compressed air.
And the range of a car on compressed air is 10 to 15 miles at best.
Aria Doherty's sister found her in bed with a can of compressed air cleaning product attached to her mouth.
That is expensive, as is the compressed air required to feed the guns.
In a moment of inspiration, Garvey realized that air could be compressed using a wind turbine or a wave-powered device.
In addition to nukes, OR-SAGE also examines advanced coal with carbon capture and storage, solar and compressed air energy power plants.
Instead of moving a physical surface, fluidic controls divert the airflow over a wing by blowing compressed air out of narrow slots.
National University of Singapore industrial design students Gabriel Tan and Wendy Chua's prototype uses negative ions, compressed air and anti-bacterial deodorants to clean clothes.
The first carries compressed air, water, communications and a constant supply of electricity to power lights that are intended to simulate daytime and nighttime.
In 1990 an equivalent gun would have used 15 times as much compressed air as water, and thus been far more expensive to run.
This somewhat dangerous device had a six foot barrel, was made out of PVC irrigation pipe of varying diameters, and was powered by compressed air.
There are no fixed walls, and each deck is hollow, allowing technicians to run compressed air, electricity and data feeds to wherever they are needed.
And rather than relying on salt caverns, SustainX uses standard steel pipes to store the compressed air, allowing its systems to be installed wherever they are needed.
Ours use compressed air, which can be stored -- that makes a big difference if your fountain goes bang into the sky only once every 15 minutes.
Philip John, the technical director of the project, says the version used on Demon has the compressed air entering a single chamber within a wing's trailing edge.
Based at Nottingham University, Professor Garvey -- whose interest in wind turbines stretches back to his school days -- began his research into compressed air storage two years ago.
The GE team began its energy treasure hunt at Weidmann by shutting down everything at the factory and searching for things like lights unnecessarily left on, compressed air leaks and running water.
RAPHaEL -- which is part of a larger RoMeLa robot project named CHARLI -- has already won several awards, including grabbing first prize at the 2008-2009 Compressed Air and Gas Institute Innovation Award Contest.
ENGADGET: Robotic hand controlled by compressed air grasps the concept of delicacy
The Robotics and Mechanisms Laboratory (AKA the RoMeLa Project) at the College of Engineering at Virginia Tech has designed and built a prototype robotic hand that is controlled and operated by compressed air.
ENGADGET: Robotic hand controlled by compressed air grasps the concept of delicacy
Compressed air blows away any factory gnorts, the body is inspected for tiny defects and degreased using an environmentally safe water-based solution and surfaces are wiped with tack cloth in between each process to remove dust.
Congratulations to energy entrepreneur and PITCH 2012 speaker Danielle Fong for closing the Series D round of venture financing for her Berkeley-based startup (working out of the former Scharffen Berger chocolate factory) to pursue a solution to the energy storage problem with compressed air.
The car's limited range would require plenty of fill-ups at compressed-air service stations, except those don't exist.
The second-biggest form of bulk-energy storage, though it is dwarfed by PSH, is compressed-air energy storage (CAES).
Compressed-air plants are inefficient, and so they are commercially viable only in places where the price of power varies dramatically.
ECONOMIST: Compressed air might help to make wind power more reliable
At any rate, a group of municipal power companies in the American Midwest reckon that building a wind-powered compressed-air plant to take advantage of the blustery Great Plains will be worthwhile.
ECONOMIST: Compressed air might help to make wind power more reliable
At the moment, however, there are only two compressed-air energy-storage plants in the world (one in America and one in Germany), and neither was built to make use of wind power.

But they have not been widely adopted because they have to be accelerated to Mach 1 (the speed of sound) before the air inside them becomes compressed enough for them to work.
While the International Air Transport Administration also considers compressed gas cylinders hazardous in general, the body approves of the avalanche-specific canisters for either checked or carry-on luggage, thereby making the US the only country in the world to prohibit them. (Passengers outside the US are, however, required to inform the airline before their flight that they will be transporting the system).
