The energy required to refill the compressed air tanks reportedly costs about $2, and there are optional propulsion units to extend the roughly 90-mile (at speeds of 40mph or below) range of the ...

The global dependence on fossil fuels, especially in transportation, has dire consequences. These fuels are the largest ...

Analysis showed the air propulsion system to be superior to both battery- and fossil-powered boats. Compressed air provided a ...

the very air we breathe could provide propulsion for our vehicles. Who would have thought that a concept as simple as compressed air could be a viable automotive technology? Sure, we all fill our ...

The compressed air system at the German Aerospace Center (Deutsches Zentrum ... used to supply the high-pressure combustion chamber test rigs at the DLR Institute of Propulsion Technology and the wind ...

In the usual jet-propulsion machine, air is taken in at the front, compressed by a turbine-driven mechanical compressor (e.g., a fan), then mixed with fuel in a combustion chamber and expelled at ...

The innovation comes in the drivetrain, instead. The boat uses compressed air for propulsion, stored in a battery of four soda bottles, pressurized to 6 bar. The compressed air is used to drive a ...

Heating Facility in Cologne consists of three large fossil-fuel-fired compressed air heaters. These, in combination with other supply systems, feed the high-pressure combustion chamber test rigs ...
