“How can we describe the power output density capability of a particular device?”

Power supply is one of the foundations of modern technology. But some devices can supply more power than others. The amount of power that can be supplied by one mass unit of a material is known as the Power Density. In batteries, power density is usually contingent on the current output as voltage is typically held constant.

“How can we have a safe form of carbon which can’t easily escape into the atmosphere?”

Carbon is one of the most fundamental elements in the world. Given its role in energy production and global warming, it is both the foundation and destroyer of our civilization. But can there be a cleaner form of carbon? Well, if we burn dead organic matter such as plants in a container with very little oxygen, then it will release very little fumes and turn into a stable form of carbon known as Biochar. The energy created in the burning process can be used to power mechanical processes.

Quantum Dots for Solar Panels

“Why are quantum dots for solar panels so useful?”

 

Quantum dots are bringing a revolution into the world of semiconductors. And since semiconductors are the backbones of solar panels, things will be greatly changed for them as well. The extra emissivity offered by quantum dots means that two and possibly three electrons can be generated for every photon received, vastly increasing its potential! Quantum dot solar panels can achieve as much as 65% efficiency, nearly double of the theoretical limit of normal panels. This is why Quantum Dots for Solar Panels are so exciting.

“What is the next big revolution in semiconductors?”

 

Semiconductors technology is going through a revolution. Nanosize semiconductor materials known as Quantum Dots which can give off light when illuminated are starting to be developed. Their small size allows them to be much more efficient than typical semiconductors and can give off a broader range of lights.

How Tree Trimmings Could Help Build Power Resilience

“How could trimming trees help prevent blackouts?”

 

Grid failure happens all the time. But one of the most common causes actually stems from something very simple, trees! Tree foliage produces an area that is sensitive to burning and is also liable to falling down, crushing distribution. By taking away some of this foliage, some of this resiliency liability. This is How Tree Trimmings Could Help Build Power Resilience.

“What is the byproduct of nuclear energy?”

 

Nuclear energy is one of the promising power sources for the decarbonized future. However, like everything in this world it comes with serious consequences. The spent Uranium fuel rods will still give off enough radiation to kill a person for a quarter of a million years, meaning that this High-level Radioactive Waste must be contained somewhere.

“What is a more optimal fuel than gasoline?”

 

While gasoline is the most widespread vehicle fuel in the world, recent advances in science and technology have created competitors. One in particular comes in the form of Methanol Fuel. Methanol fuel is synthesized from carbon dioxide and hydrogen burns cleaner and is cheaper to produce sustainably than ethanol. Since it does not produce a thick cloud of smoke upon use, it is often used in racing applications. Although methanol is less toxic than petroleum, there exist very few methanol refueling stations, it is commonly found in a mixture with other fuels.
