Cooling Your Home For Free
I am of the opinion that climate change, and the resultant increase in yearly temperture events aka heat waves, is going to be a major source of deaths in the coming decades. I'm sorry, forget 2 degrees as a target, we are probably looking at 4 degrees for sure if not 6.
If you aren't one of the 9point9 percent of economic elites, and can afford to just turn up the AC, then prepare for a lot of sweat.
(For an article on why its not the "1 percent" any more, click here: https://www.theatlantic.com/magazine/archive/2018/06/the-birth-of-a-new-american-aristocracy/559130/ )
So anything that helps me stay cool and is free and I can build myself is great. Enter this invention from Bangladesh.
"Bangladeshi inventor Ashis Paul has figured out how to re-purpose plastic bottles into a low-cost, easy-to-make, electricity-free air conditioner that can help the country's poorest better tolerate the sweltering summer heat.
The science behind the Eco-Cooler is based on the idea that the bottleneck becomes a funnel that compresses and cools the air that runs through it by about five degrees, according to the Eco-Cooler website. It's the same principle that governs blowing air through pursed lips — the air comes out cooler despite the body's 98-degree-Fahrenheit temperature."
