“What happens when a community lacks sufficient access to energy resources?”

 

In the developed world, it is hard to imagine not having access to electricity. But in many parts of this the developing world, this is a pure reality. When a community lacks sufficient access to energy, they are said to be in Energy Poverty. Energy poverty can affect all factors of human development, such as emergency medical situations not having enough power or children not being able to do homework at night because of lack of access to lighting.

“How can a Supergrid help Grid Resiliency?”

 

Distributed Energy Resources have a problem. They tend to generate a large surplus of energy at midday when it is not needed, and a dearth at night when usage goes up. But some outside of the box thinking can fix this problem. We know that because the Earth revolves around its axis every day, different parts of the surface will be exposed to the sun at different times. So what if we were to take the surplus energy at the sunny parts and send it over to parts where the sun is absent using a Supergrid? In this way, A Supergrid can help Grid Stability.

“How can we regulate vehicle emissions?”

 

Much of the debate around decarbonization centers around the energy sector. But in some areas such as California, the transportation sector have become the highest emitter of CO2 emissions. To combat this, governments can adopt Vehicle Emissions Standards which regulate how polluted vehicle emissions can be.

“How can we measure an object’s surface temperature?”

 

Engineers and Scientists love to measure things. And one of the most important things to measure is often the surface temperature of objects. So how can we accomplish this? Well, we can use a thermistor with a specialized shape for surface monitoring called a Surface Temperature Probe to accomplish this.

“How can we isolate vital components from isolation?”

 

Vibrations happen all the time in mechanical systems. But sometimes we may want to protect vital components from them. We can do this using a technique called Vibration Isolation which shields the desired piece of equipment from vibration.

“How can we measure the albedo of a surface?”

 

Knowing the Albedo of a surface is very useful, whether it be for deploying solar energy or making scientific measurements on the moon. But how can we accomplish this? Well, by placing one pyranometer towards the sky and another one facing the surface, we can find how heavy the albedo is. These instruments are known as albedometers and are great for many purposes.

“How can we classify wastewater without fecal matter?”

 

Water is used in homes for all sorts of purposes. Whether it be for taking showers, flushing the toilet, or even washing clothes, water is apart of the equation. But can we reuse any of this water once we’re done with it? Well, as long as there are no biohazards such as feces in it, we can recycle it as Greywater for other purposes. Reusing Greywater is one of the most powerful actions a community can take to increase their sustainability.

“How can we make a building that uses no energy?”

 

Net zero energy usage in buildings can mean two things. Either all of the energy consumed by the building is met through self-generation or the building itself uses no energy! The latter is the foundational idea behind Passive Buildings. Passive buildings are edifices that obtain all of their heating and lighting through natural means. This means that such buildings have lots of large windows to let natural sunlight in, are superinsulated, and employ passive solar design. Therefore, these buildings can skip the need for complex lighting and HVAC. Passive buildings are amazing to experience and should be enjoyed by everyone in my opinion.
