Non-polluting cryogenic (pneumatic) automobile

Description

Now there is great necessity in renewable energy sources and in energy-conservative technologies. It is important also, that these sources and technologies were ecologically friendly too. We developed an experimental sample of the mechanical engine that meet above mentioned requirements. In installation as a working medium it is used the liquid nitrogen, which are storied in liquid state in the heat insulated tank and can be supplied into an air heat exchanger, where it is gasified and heated by a heat of an environment. The heated gas in suppressed state is supplied into pneumatic engine performing mechanical operation in some special system (for movement of the car, for actuating an electric generator etc.). The experimental cryogenic car with similar installation is shown in picture. Power of this installation is of 0,7 kW now.

The liquid nitrogen is produced by special air-fractionating apparatus. For production of the liquid nitrogen in amount of 1 kg it is required about 1 kW-hour of electric energy. The electric power can be received from hydraulic stations, wind stations and from ecologically friendly nuclear power stations. Such processes can be organized without usage of a nonrenewable resources of hydrocarbon fuels. Applying of the proposed engines leads to saving of such power source. They are ecologically absolutely friendly and can use renewable energy sources (river and tidal stations, wind, the sun) for production of liquid nitrogen from air. With allowance of high calculated efficiency coefficient of pneumatic motor (up to 60 %) in particular and the exceptions of a harm for environment of cities by internal combustion engines (ICE) offered engines for a urban transport economically are more favorable, than ICE and do not consume gasoline.

Innovative Aspect and Main Advantages

Useful mechanical work obtained by warm of atmosphere air.

Engine work body is liquid nitrogen or liquid air.

The engine does not use conventional hydrocarbon fuel in comparison with ICE.

The engine does not burn oxygen of atmosphere in comparison with ICE and it is fireproof.

The engine on an offered principle is non-polluting in comparison with conventional internal-combustion engines (ICE) and eliminates diseases of the people in cities.

The engine eliminates hazard of fires from transport vehicle.

The engine is cheap at production, at operation and utilization.

The engine can have temperature below, than the environment, that makes its invisible in infra-red band of wave lengths (in comparison with ICE).

The engine requires more fuel (liquid nitrogen or air) onboard in comparison with quantity of petrol for ICE, but this lack is indemnified by the low cost of liquid gases and capability of more often refilling by liquefied gases.

Areas of Application

  • Ecology pure and fireproof cars for city, plants, warehouses and airports.
  • Invisible in infra-red radiation region vehicle for contra terrorism operation.

I was curious if youu ever cconsidered changing tthe strudture
off your website? Its very well written; I love what
youve got to say. Butt maybe you could a little more in thhe way of
content so people could connect with it better.
Youve gott an awful lot of text for only having 1 or 2 pictures.
Maybe you could space it out better?
