“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.

Ultracapacitors for EVs

“What is one possible way to speed up EV recharge times?”

 

In order to achieve deep-decarbonization of transportation, the global vehicle fleet needs to become much more electrified. However, the long recharge times associated with electric vehicles are a roadblock for this to happen. One way to solve this would be to implement Ultracapacitors for EVs. Ultracapacitors have quick recharge times, low weight, and low degradation, making them a formidable option. The downside is that manny ultracapacitors lack the storage capacity found in traditional solid-state batteries. But if this problem gets solved, then expect a paradigm shift in the EV industry!

“How can we use synchronous motors to stabilize the grid?”

 

Synchronous Motors are great for precision control applications. But their usage can be applied to grid stabilizations. Since voltage in a grid can fluctuate, by running synchronous motors at no-load speeds we can effectively have a load that adds inertia to the system, therefore mellowing out the voltage fluctuation. These devices are known as a Synchronous Compensators and are a vital part of the modern grid.

“Is there a control method that tries to sets a function at its extreme value?”

 

Control Theory is a deep subject. There seems to be a control method for every situation. And one of those situations might happen to be one where people are trying to keep a function at its extremum (the maximum or minimum absolute value). This Extremum Seeking Control allows for this to happen, and also gives it the privilege of heightened sensitivity reduction and disturbance rejection.

“What makes autonomous vehicles work?”

 

Autonomous vehicles, archeological scanning, soil imaging, and automated agriculture all rely on knowing real-time distance to work. However, how exactly can we accomplish this? Well, let’s use our engineering mindset to find out. We know that if we send a beam of light from a laser somewhere, then it can be reflected back. And since the speed of light is constant in a uniform medium, if we measure the time it took to return, we can obtain a measurement for distance. This system is known as LIDAR Scanning,  which stands for Light Detection and Ranging. LIDAR has caused a revolution in multiple fields of science and is moving every day closer and closer to mainstream adoption.
