In a Flash

Multi-stage flash water desalination is a process that turns saltwater into drinkable water. Abbreviated as MSF, this process works by using heat exchangers and condensers to turn water into steam, and then back into water. While this method is unfamiliar in the United States, it is the most common drinking water treatment in Saudia Arabia and other desert biomes such as Kuwait and United Arab Emirates.

Activated Sludge

Imagine you are on a conveyor belt. The conveyor belt is circling around a box of pizza. Every time you get close enough, you take a slice of pizza. If the conveyor belt moves too fast, you can’t grab the pizza. But if it’s too slow, you’ll starve and the pizza won’t be nice and hot anymore and it might even start to grow mold. This is how the activated sludge process was explained to me in my first Environmental Engineering lecture many moons ago.

Exotic Pet Ownership

The majestic yet venomous (and very invasive) lionfish fromĀ Hakai Magazine.

Lately I’ve been pondering what type of pet I’d like to own when I finally move out of my college dorm and into the real word. During my time searching the interwebs, I discovered several exotic and even wild animals that I could easily purchase online, such as sugar gliders and even fennec foxes. After a couple minutes, I found myself stumbling on article after article that advocates against owning novelty pets. And so the moral debate begins.

Atmospheric Water Generators

Typical Atmospheric Water Generators (AWGs) don’t work well in environments with low humidity or temperature. Scientists at Massachusetts Institute of Technology (MIT) found a way to extract water from soil in the driest biome in the world- the desert. Using an air-cooled sorbent-based atmospheric water harvesting device, the research group predicted that over a quarter-liter of water could be extracted per kilogram of metal-organic framework (MOF) each day.
