Cryogenic Nitrogen engine fuel -Can it be condensed 3

[jacklngpower]

Can a piston engine run on cyrogenic Nitrogen and the exhaust recyled to the storage tank ?

I don't proclaim to know much about gases...but isn't nitrogen inert?

Has anybody out there heard of the use of Cryogenic Liquid Nitrogen as a 'cool' fuel to expand from cool liq.to hot gas as it either pushes a Turbine or a piston to turn a
output shaft? I read a paper by univ. of washington at seattle,WA. That Cryogenic Liquid Nitrogen can be used to power a Zero emission automotive vehicle 140km from 200 liters of LN2? Could this be practical for light weight 2 -4 passenger vehicle? Is their any work going on in this region of automotive propulsion research ??

Google compressed air engine

to get the basics.

Running an engine on LN2 cryogenically maintained at -320 f . Is any work being considered that would fly as a stationary power unit like they use now with Natural gas for power peeking units ?? Would like to find any work being done that could bypass the need for oil , gas , natural gas , kerosene, diesel you name it !!!!!!!!

Nitrogen is not inert in the real sense. Recall that nitrous Oxides are an issue even with hydrogen combustion. Look on the column with Helium for the actual inert gasses like argon, etc.

The liquid nitrogen thing sounds like a fun project. However, as an environmental deal, somewhere they must have air-separation plants with electrical driven compressors and refrigeration stuff to bottle the liquid nitrogen. The energy would be used on the production end instead of sourced from combustion of the fuel. I don't see zero sum either.

A piston engine does not need to have combustion.

In order to run an expansion engine with liquified gas there must be a heat source to vaporize the liquid which then expands over the piston to produce work.

What will the heat source be?

And, of course as jsummerfield pointed out, how much energy will be wasted to produce the liquified N2 in the first place?
