Hello,
I filed a new patent for the storage of energy with liquid nitrogen, it is a motor capable of producing liquid nitrogen and using the liquid nitrogen previously produced to restore the mechanical energy.
The improvement I bring is that the engine is able to use the cold of liquid nitrogen just as it improves the production of liquid nitrogen.
Thermodynamic calculations give 240 Wh per kilogram of liquid nitrogen for 240 Wh of energy to produce 1 kg of liquid nitrogen.
the overall yield should be around 60%
The patent will be published in the official newspaper Friday 16 March 2018 ... after tomorrow.
in the meantime here is the site https://www.eric-dupont.in

Uh, can you develop?

The return of Eric DUPONT,
I do not make any judgment about your patent / engine, but your site ...
"digit counter": the numbers are bogus.
And spelling too! in my opinion this page does not bring anything.

Re: Liquid nitrogen generator engine
The positive side: beautiful photos (which have only an allusive report to the process) and translations in several languages (as incorrect as in French ...).

Re: Liquid nitrogen generator engine
do not worry, I will develop since I filed a patent application as you advised me.
the pressurized liquid nitrogen from the tank passes into an exchanger where it is vaporized. Then the nitrogen is expanded in the engine with a water injection. 160 Wh / kg of nitrogen is obtained.
The invention is as follows. the air that passes through the exchanger to heat the liquid nitrogen is thus cooled to very low temperature, about -150 ° C, this air goes into a compressor where it is compressed at 40 or 50 bar, the temperature of the air rises to 20 ° C. the air is then relaxed in the engine with a water spray. this small system increases the energy recovered by 80 Wh / kilogram of liquid nitrogen.
That's it, it's patented.
the engine is also reversible in liquid nitrogen generator, the compressor allows to relax the cooled nitrogen in the exchanger while the engine compresses the nitrogen.
it's patented.

So the "invention" consists in compressing air via a compressor in order to immediately expand it in an "expander". It’s amazing ...

Re: Liquid nitrogen generator engine
yes, adiabatic compression, followed by isothermal expansion.
