“What exactly are single-use plastic and why are they so bad?”

Plastic is a very useful material. It’s flexible, fairly non-reactive, and strong, making it applicable for single-use grocery bags. However, the fact that Single-use Plastics are not recyclable and biodegradable means that they will end up in a land-fill and release toxic chemicals into the environment. To solve this crisis, a new generation of thinkers will have to come up with innovative policy and technical solutions. This could be anyone, from a regular Joe to someone whose name rhymes with Narina.

“How will the increasing frequency of droughts affect conventional power generation?”

Although usually thought of as being completely self-sufficient, conventional power generation relies a great deal on water for its operations. With the increasing frequency of droughts induced by climate change, water will become a more scarce resource in many parts of the globe, therefore reducing a vital feedstock for conventional power. This is How Climate Change Induced Droughts Will Impinge upon Conventional Power Generation.

“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.
