Suggestion for Debunking: Green Kinoko - Wirld first Liquid-Nitrogen outdoor A/C

[polwath]

It was announced as the world first liquid-hydrogen air conditioning for outdoors. I start to worried about the product itself maybe a pure BS marketing and it may pose a safety concern to users too.



I found this news article introduced this product in my local IT news site in Thai Language. But it also reference the link to the source which it has article in English here.

If anyone has knowledge or expert in A/C and chemical engineer, please check this product and debunk this.
As it contain dangerous chemical inside which can casued serious danger to environment and users. Also I doubt their claims in cost and duration of this product as comment in news article also show the same concerns on this product.
