Liquid nitrogen engine

Why does the barrel jump

Fascinating experiment, but I'm trying to grapple with why the barrel jumps in the air. The propulsion of water out the top should press the barrel down, not up.

You can't pick yourself up with the bucket handle when standing in the bucket.

A rocket goes in the opposite direction to the ejected mass.

Curiously.

When the liquid nitrogen in the bottle reaches its critical phase change temperature, it suddenly expands to 698 times its volume when it was a liquid!

This drives the water in the barrel and the air above the barrel away with such a sudden force that a "low pressure area" around the barrel is created just like what happens in a cyclone or tornado and this creates a lifting force on whatever is within the low pressure area i.e the barrel.

Well the barrel rose probably about 2.5 feet into the air but instead of putting LN2 in a bottle and dipping it in the barrel of water, if the same experiment was done by seating the barrel on another smaller barrel in which the LN2 was introduced, then the original heavy water filled barrel would have risen like a projectile or rocket.

The thing to understand here is the massive expanding power of liquid nitrogen upon phase change from liquid to gaseous state can wonderfully be used to drive a piston of any ICE or piston based engine.


Compare the piston driving capability of superhot steam, gasoline, diesel and liquid air. All are performing the same thing except that there's no combustion in liquid air/nitrogen and steam but liquid air has 100 times the driving capability than superhot steam. That's what Charles E Tripler says in "Liquid Air: Perpetual Motion at Last."

Certainly there are millions of diesel engines operating all around our Planet. As simple ambient heat is all that is required to trigger the phase change of LN2 to gaseous state, the compression ignition engine such as the diesel engine should surely work on it. Once we practically verify this uniform working on diesel engines of various bore/stroke/air volume/horsepower capacities, we have already crossed a big hurdle.

The new kind of fuel is already having engines designed for it which are widely being used since a very long time but unfortunately on fossil fuels.

Liquid air can also be used in gasoline/petrol spark ignition engines but needs elimination of the standard air/fuel mixing carburetor.

With correct application of mind i am sure the existing topologies of fuel injection of the diesel engine can be made hybrid i.e to run on liquid air or diesel fuel once again. The day the production of liquid air can be done in an extremely economical way and right in your own garage which Charles E Tripler said is definitely possible, we then may not need to worry about running out of liquid air anymore.

The making of "10 gallons for every 3 gallons used" definitely encourages us to believe the conception of an onboard re-liquefier so that we always have a significant supply on-the-move in the case of automotive application and dont need to depend on a refilling station.

The making of Liquid Air at low cost

Now the final hurdle is to make liquid air in a very economical way. This link Publication - The Unz Review

Of interest

To extend the liquid nitrogen theme. Liquid air is the same process without purifying to nitrogen, here's a link to making it at home -

To enhance the output volumes, warm gas option -

Tridyne gas is inert and can be made on site. There is a range of mixes in the US patent but in rough terms it is : 5% Oxygen 15% Hydrogen 80% Nitrogen.

It is catalysed over noble metal (gold / silver / palladium / etc) and burns to 1400 F (ish). Again there is a patent indicating how this temperature can be modified by passing only a small amount over the catalyst and combining with the bypass gas. One of the benefits with warm gas emission is it helps save the liquid by moving towards volume ejection vs mass ejection.

All very interesting stuff.
