I See a Disturbing Lack of Net Power Calculation

In this story about an interesting idea of making wind energy portable or able to be stored in some fashion, the omission of net power with current turbine engineering belies its conceptual usefulness. The idea of using wind energy to liquify nitrogen, then let it expand again to fill in turbine downtime is novel, but the net power consumption does not even come close to rivaling battery technology right now. Either the turbines need to produce much more power, or the liquification process needs to become much more efficient. Still, lots more basic engineering research needs to be done even to determine if this is a viable solution. Thermodynamics is not a very forgiving branch of physics.
