“What are bottlenecks to electricity transmission?”

Electrons moves along transmission lines analogous to cars through a freeway. And like cars, if there is too much trying to get through at the same time, it leads to complete obstruction. These transmission bottlenecks are the bane of every utility, and will become a hindrance for renewable energy as peak electricity production hours often leads to a sudden surge of new electrons.

“What is the type of air pollution that makes skies blurry?”

One of the most famous visuals of the effects of air pollution are the blurry and disrupted skies. Whether it be from the urban centers of India, the smokestacks of Chinese factories, or the wildfires in California. One of the main causes of this is from particulate matter the size of 2.5 microns, commonly referred to as P.M 2.5. P.M 2.5 arises from burning materials and can travel deeply into the lungs of humans, causing intense medical damage.

“How can levees perpetuate climate inequality?”

Levees are used by civil engineers to prevent rivers from overflowing. However, this can cause the flood to become worse at the other end of the levee, and harm an area further down which does not have the capabilities to defend themselves. This is How Levees Can Perpetuate Climate Inequality.

“How is the majority of electrical energy made?”

Energy is the backbone of modern infrastructure. Whether it be for making our coffee or powering our stock-markets. And the majority of this runs on the earliest version of this technology, in which water or another fluid is heated and evaporated to run a turbine to make Thermoelectric Power.

“How is water quality affected by wildfires?”

Wildfires are infamous for spewing toxic fumes into the atmosphere and destroying air quality. But what’s lesser known are its effects water quality. Because watersheds are more susceptible to flooding and erosion as well as causes sash to settle in water, disturbing the water. This is How Wildfires Can Affect Water Quality.

“How do exhaust systems for biology labs work?”

Chemical fume hoods are vital for exhausting noxious fumes from scientific labs. However, biology labs have needs that are more sensitive. Since they are dealing with live organisms, fumes from their lab spaces cannot mix with others and exhaust air will need to be more filtered. For this reason, Specially designed Biosafety Cabinets will have to be used.

“How can we measure how porous an object is?”

If an object is porous it means that it has empty space in it. The measure of this empty space is known as the Porosity, and can be found on a sliding scale from zero percent to one hundred percent.
