“How can we prevent the overflow of rivers using built infrastructure?”

Rivers can be the lifeblood of a community, whether it be for transportation or a source of drinking water. However, when the river floods, it can cause great disaster to a community. So how can we artificially prevent such flooding? Well, what if we were to build barriers right next to the river flow running parallel? These Levees are a staple of river control around the world and have saved countless of lives.

“How can we lower the freezing point of water?”

Water is known for its important freezing point. In fact, the entire metric temperature system is based off it! However, sometimes we may need to lower its freezing point. This can be accomplished through Antifreeze substances. Antifreeze is usually based off mixtures of water and either ethylene glycol (EGW) or propylene glycol (PGW). Antifreeze has plenty of applications, ranging from automotive engines to electronics cooling.

“How can we bring electricity to rural households?”

Much of the developing world still has no access to electricity. More than 15% of people in India and 87.5% of rural sub-Saharan Africans are unable to enjoy the right to modern infrastructure. This can be solved with Rural Electrification, which entails expanding the grid or distributed energy resources to marginalized communities.

“How can we make fume hoods better performing?”

Fume hoods are a vital component for any scientific lab. Without them dangerous fumes would not be able to be ventilated away and people working in the lab could have their lives at stake. When common solution is to implement a CAV fume hood. However, the fact that the air volume exchange rate does not vary leaves it with performance and energy inefficiencies. This can be solved by implementing VAV Fume Hoods (Variable Air Volume) which can change its air intake when needed. Labs that implement this often see great strides in performance and energy effectiveness.

“What are the simplest types of fume hoods?”

Fume hoods are used to take in fumes from chemical lab stations and ventilate them into the atmosphere. The simplest type is where the fume hood releases the same amount of air at a constant rate all the time, no matter what. These CAV Fume hoods (Constant Air Volume) are the simplest type of fume hoods available. The fact that they cannot change their air velocity in response to external stimuli means that they give sub-optimal performance.

“What is the most common type of fume hood?”

Fume hoods are a vital part of scientific labs. The most common type is usually a Ducted Fume Hood design where conditioned air is drawn from the lab space and siphoned into the outside atmosphere. The simplicity of the design has made it a staple of labs across the world.

“How do scientists ensure that they are safe from chemical fumes in the lab?”

Biology and Chemistry often involve a lot of messy lab work involving chemicals, which may give off dangerous vapors. To prevent these from damaging the air quality in the lab and the health of the denizens, the fumes must be cycled away. This is commonly done through fume hoods, which sucks in air from a workbench and ventilates it to the atmosphere. Fume hoods are a vital part of the safety of every lab and have become a staple of the wet-bench research environment.

How the Speed of the Energy Transition Is a Self-Fulfilling Prophecy

How the Speed of the Energy Transition Is a Self-Fulfilling Prophecy

09/13/19

“How might the speed of the energy transition be a self-fulfilling prophecy?”

One of the most hotly-debated topics in the world right now is how fast the transition from a coal and fossil-fuel based energy paradigm to a cleaner renewable ones will be. Many say that it will be fast and exponential thanks to the precipitous price-drops in solar PV technology and others say that infrastructure lock-in will slow it to a crawl. However, the public’s belief in how fast the transition will go will modify support and pressure for new technologies and systems to be available. Therefore, if people believe that it will go fast, it will! This is How the Speed of the Energy Transition Is a Self-Fulfilling Prophecy.
