“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.

“How can engineering simulations save companies a lot of money?”

 

Before the ascent of computers, most engineering modeling had to be done with physical experiments. These were arduous, costly, and prone to failure. But with the invention of simulation, companies can now simulate their designs’ performance without having to actually build it. This is How Engineering Simulation Can Save Companies a lot of Money.

On Convergence of Infinite Sums

“What is so special about infinite sums coming to a specific value?”

 

1

We have all seen the classic sum.

2

Which is often represented as…

3

We, in our high school careers, have been taught that this sum is 2. This is
most often done so with an algebraic manipulation of both sides of the sum. We
haven’t been taught how to verify this sum. But how would we go about doing
this?
The basic idea is that if I end my sum at nite point, my result will deviate
from the actual sum by some error (which we will call ε. This error is some
positive real number. To verify that this sum indeed approaches 2, it suffices
to show that for any error, there exists a nite point in the series in which the
difference between 2 and this point is less than the error AND all further points
will also be less than the error.

“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.

Why HVDC Can Hurt Fire Resilience

“Why are the most serious drawbacks to HVDC lines?”

 

HVDC lines are one of the hottest topics in the renewable energy world nowadays. Their ability to transmit a large volume of electricity across great distances with minuscule losses can make them a vital part of easing the duck curve. However, their high voltage also means that if they get sapped, they have a much higher potential to produce a fire. This will have great implications for the regionalization of California, where increased connectivity to other states could bring grid stability but exacerbate the potential for chaos.

“What happens to total cost if one more unit is produced?”

 

Everything in economics has a cost associated with it. And these costs and can be divided into different categories. Take a factory producing solar panels for example. There is already a base cost with operating the factory, and the total cost for each unit of production. This is known as the Marginal Cost and can be used in risk assessment of engineering projects. Sometimes when more units are produced in a given span, the cost goes down because of economies of scale, while other times it goes up.
