Negative Carbon Emission Technologies

“How can we use technology to remove carbon dioxide from the atmosphere?”

Humanity is reaching a crisis point. We are adding so much carbon dioxide to the atmosphere each second that we will soon reach irreversible climate damage. To solve this, we’re going to need to use every technology we have at our arsenal, whether it be wide arrays of solar panels or intense energy efficiency measures. But the true kingmaker of solutions comes from a group of technology that is still quite ominous and undeveloped. These Negative Carbon Emission Technologies work by using a series of processes to store more carbon dioxide than they produce. This can be done in a multitude of ways, whether it be through planting more trees or capturing carbon from the atmosphere and shoving it down into the ground. With these solutions, we can tip the odds in our favor in our fight for decarbonization.

“How are water and electricity directly interrelated?”

Water and electricity, two of humanity’s most vital resources, are often thought as being from completely different worlds. However, the reality is that the generation of one resource uses some of the other! To illustrate, water needs to be pumped through mechanical pumps reliant on electricity while power plants use water for their operation. In this way there is Water and Electricity Interdependence. So every time you let the faucet run, you’re not only wasting water but also electricity!

Digitization and Its Implications for Manufacturing

“What is digitization and how will it affect manufacturing?”

With the rise of the industrial internet of things, engineering processes are moving more and more towards the digital realm. This means that components once limited to the physical realm, such as mail and design models, are moving into the virtual one as e-mail and CAD. This digitization will have a lot of ramifications for the manufacturing sector, where processes will now be less prone to human error and move a lot faster while being more prone to cyber-security issues. This are the Implications for Manufacturing from Digitization.

“Why will the lengthy longevity of cars impede climate progress?”

The transportation sector will need to become electrified in order to achieve decarbonization. One way to do this is to shift fleet compositions from petroleum to electric-powered vehicles. However, because vehicles tend to have lengthy longevity, they will be retired at slow rates, impeding turnover to electric vehicles. This is Why The Durability of Vehicles Will Make it Difficult to Electrify the Electricity Sector.

“How can we reduce energy demand for washing machines?”

Washing machines have become fundamental to human life. However, they are also extremely energy intensive and intense on the environment. So how can we use our engineering and policy mindset to solve this? Well, this can be accomplished with three methods.

1. Demand-side response By shift use of washing machines away from peak hours, we can ensure that not only does it tax the grid less but potentially use more clean energy.

2. Model upgrades: By replacing older machines with newer, more energy efficient models, their energy intensity will drop.

3. Reducing usage: By using washing machines less and replacing them with passive drying mechanisms such as hanging clothes, energy consumption will drop.

All of these are How to Reduce Energy Demand for Washing Machines.

“How can flameless cooking be done through magnetism?”

Preparing food is one of the most important elements of human life. Every culture has placed some form of emphasis on it, and cherishes it to the utmost. However, in the past in has relied on burning gas, coal, or wood to operate. Not only is this dangerous to the environment and human health but is also inefficient. But with the advance of new technology, cooking can be done in an entirely new way. Instead of having separate burners, the cookstove can be a flat magnetic plate. When activated, the magnets will induce eddy currents into the cookware, generating heat and cooking food. Not only is this much more energy efficient but also uses no flames! This Induction Cooking is a great way to decarbonize the world of cooking.
