The path to creative climate solutions is paved with the skeletons of a million startup. Blue Frontier received a big check from Bill Gates, who was impressed by the company's use of a concentrated salt solution.
The issue with our modern AC technology is twofold, as most of us try to beat the heat in the dog days of summer. Air conditioners emit greenhouse gases and are dirty. As climate change makes heat more frequent, we are going to have to rely on dirty air conditioning to stay comfortable. Blue frontier entered.
Blue Frontier is a startup based in Florida. Blue Frontier received $20 million from Bill Gates' clean investment fund, because the company claimed that their new technology could reduce energy consumption by up to 90%. Blue Frontier is looking to cater to non-residential buildings and new buildings that can support a rooftop unit with no indication of when or if this technology could be scaled down into something like a window unit for an apartment.
Blue Frontier didn't immediately reply to our request for comment on how their technology works, but a report on the company's website shows how it works. Blue Frontier claims that the cooling comes from a proprietary salt solution that behaves as a desiccant and is sealed from the atmosphere until air conditioning is needed. When the concentrated solution comes into contact with the air, it will dehumidify the air by absorbing water vapor and then reduce the air's temperature through indirect cooling. They said so.
When I see this technology, I will believe it. There are a million variables standing in the way of seeing a widespread roll out of Blue Frontier's product, even though Bill Gates' stamp of approval is promising.
