It goes without saying that global warming has already wreaked havoc across the globe, and recently, we have seen how badly climate change has affected the regions across Europe in terms of extreme heat waves. With this in mind, an Israeli company, Green Kinoko, is on the verge of launching an incredibly seamless outdoor cooling system that is based on liquid nitrogen. The idea is surprisingly simple as it provides cooling to several tables without the cost of any electricity. Not only this, but the process is also environmentally friendly, unlike air conditioners, as it uses nitrogen that is abundantly found in our atmosphere, i.e., 78%. Now you can dine out easily, even in hot temperatures. This is amazing, isn’t it?
Liquid nitrogen is conserved in the standard tanks at a temperature of about -196 degrees centigrade (-321 degrees Fahrenheit). The liquid is then cooled by placing it into coolers, which then expand after transforming into a gas state. The rate of expanded gas is 700 times that of liquid. However, it should be noted that a mechanical engine is used to further propel the nitrogen into the atmosphere so that it may reach the tables evenly. The mechanism is perfectly suited for cooling the outdoor environment; this is no small feat.
Coupled with this, Green Kinoko’s Moran Goldberg stated, “Usually, the cost of the nitrogen is about €50–60 (US$50-60) per tank. Today, it’s mostly produced as a byproduct when hospitals and medical services make pure oxygen. Of course, there’s a logistics part of the equation we have to take into account in each country as well, but it’s not going to cost more than the existing solutions. As far as a restaurant or venue is concerned, the cost of owning and running an outdoor heater is what we’re benchmarking. “
It should be noted that the standard tanks have to be replaced every 7–10 days, and it depends on the amount of nitrogen that you are utilizing. Not only this, but the temperature present outside also determines the changing and refilling of the tanks. Goldberg further stated, “We’re going to run a pilot in the first or second week of September in one of the biggest cafés in Tel Aviv, and we’ll be sharing some of the results and information about the trial.” The company has been making efforts to build this system for two and a half years, and for trials, they have developed 12 prototypes to be used.
The company said that we can determine the popularity of this idea from the fact that around 40 different countries have shown a great deal of interest in our system through their inquiries. Goldberg said, “I can’t say which quarter, but I assume by mid-to-late 2023, we’ll have it ready for the mass market. At this stage, we’re looking for an investment to start production. “
