BBC short video which claims that the pollution from the refrigeration system in lorries is greated that the pollution from the lorry engine itself.

This system replaces that refrigeration system with aone based on compression liquid nitrogen that has zero pollution, though overall its pollution must also depend on the pollution from the energy source to the liqufication plant.

 

Sorry I don't know how to embed this.

If anyone can do that or tell me how I would be grateful.

You can't do it like a YT video, I think. Great idea from that chap.

Looks workable. Sounds more in line with N2's strengths.

Not great at storing energy but it can cool things easily and do some work in the process.

Here you go:

ps. Just search YouTube for the right keywords, and pick up alternative video about the same subject..

So the liquid nitrogen is used as an energy source to power the refrigerator (i.e. a heat pump), thus making the reservoir of cold more efficient.
