So, what's new in over 1,5 years? A demonstrator or a piece of a demonstrator that runs?

[Eric DUPONT]

I have an adiabatic piston expander which expanded air at 15 bar and which would be capable of expanding air at 300 bars in order to liquefy the air. and on the other hand I am creating an isothermal compressor at 300 bar which will supply the regulator. The compressor pump is running, I still have the valves and the high pressure tanks. The valves are almost finished. There may be a year of work to finish the compressor, adjust everything properly to be able to compress air at 300 bar isothermally with a good flow rate.

Lots of figures but the most important thing is missing: the yield between photovoltaic energy consumed/electrical energy returned after storage

Since you have the pumps, you will be able to calculate it and provide it to your future sponsors.

So everything's OK!

I will answer this question, in theory it is possible to obtain a very high yield but more raw materials are needed, in my opinion what matters is the overall cost of the energy which comes out taking into account that a part is stored and another is consumed directly, or even lost, compared to other energy production systems, if photovoltaic energy costs nothing we do not need to have a very high storage yield , there is the cost of the investment which comes into play. with batteries it is impossible to store large quantities

It has to be more interesting than the “hydrogen” vector for investors to be interested in it, so let’s get to work

I have a 40MPA (megapascal) 4500 PSI 300 BAR hand pump.
If that helps. I use it to inflate bikes but difficult to put in the backpack

Your pump is not isothermal, you can check, the air you inject is hot.
No, you need a 300 bar isothermal compressor that Eric Dupont is building in his garage. In a year, the matter is closed. The thread is almost 6 years old.....

Full garage in the basement does not have electricity.
It's already a start if the garage is super cold in the shade
