What are the relationship between sugarcane factory, car battery, and liquid fuel?

Depending on the context, there are several possible connections among sugarcane factories, car batteries, and liquid fuel:

Sugarcane factories and liquid fuel: Sugarcane is a popular source of biofuel, particularly ethanol, which can be made from the plant's sugars. Ethanol can be produced as a byproduct or as the primary product at sugarcane factories and utilized as a liquid fuel for various purposes, including transportation.

Car batteries and liquid fuel: Car batteries are utilized to power up the engine and electronic systems in a vehicle, while liquid fuel like gasoline or diesel is used to drive the car's internal combustion engine.

Sugarcane factories and car batteries: Although there is no direct relationship between sugarcane factories and car batteries, producing sugarcane requires a significant amount of electricity that can be supplied by batteries or other energy storage systems. Additionally, car battery production may necessitate raw materials like lithium, cobalt, or nickel that are obtained from areas where sugarcane is grown.

Overall, even though there may not be an apparent connection among all three items, they are critical elements of the modern industrial economy and may be intertwined in various ways.

Personal Project: How Hybrid-cars can reduce carbon emission?

Mr. DAI and Prof. Adi gave us a personal assignment so that we could learn more about the Energy Conversion System 2 topic. Three choices for topics were presented: pyrolysis, electric vehicles, and IC engines. Later on, Open Modelica software will be used for this undertaking.

I chose my topic of choice to be, Internal Combustion Engine (ICE). Or more specifically, Hybrid technology implemented in ICE vehicles

The majority of people are conscious that hybrid electric vehicles use less fuel than regular gas-powered cars. But not everyone is conscious of the technical justifications for it. Regenerative braking, in which the electric motor applies resistance to the drivetrain and the energy from the wheels functions as a generator to help turn the motor, is the only explanation that is frequently given. The benefits of a hybrid configuration helping to address internal combustion engines' intrinsic drawbacks are less frequently mentioned, though (ICEs).

Hybrid cars combine the use of an internal combustion engine with an electric motor and battery to improve fuel efficiency and reduce emissions. Here's how they work:

Engine: A hybrid car has a gasoline-powered internal combustion engine like a traditional car. It works in tandem with an electric motor.

Electric motor: The electric motor is powered by a battery pack that stores energy generated during braking or when the engine is running. The motor can also work as a generator to recharge the battery during braking or while the car is coasting.

Transmission: The transmission in a hybrid car is more complex than in a traditional car. It allows the electric motor and gasoline engine to work together or separately, depending on the driving conditions.

Regenerative braking: When you apply the brakes in a hybrid car, the electric motor goes into reverse to help slow the car down. This process generates electricity, which is sent to the battery for storage.

Battery: The battery pack is typically located in the rear of the vehicle and is charged by the engine, regenerative braking, and sometimes by plugging the car into an electric outlet.

Control system: A computer controls the hybrid system, managing the flow of power between the engine, electric motor, and battery.

The combination of the gasoline engine and electric motor allows hybrid cars to operate more efficiently than traditional cars. The electric motor can assist the gasoline engine, reducing the amount of fuel it needs to operate. When the car is stopped, the gasoline engine can turn off completely, saving fuel. The result is a vehicle that produces lower emissions and gets better gas mileage than a traditional car.

With that, I found interest in learning more regarding Hybrid-vehicle technologies, and how it can help in fuel economy, and in turn too help reduce carbon emissions. Also, whether or not its technology is feasible to be applied in mass. I too, will study just how big of a difference in carbon emission Hybrid cars have to a standard ICE car, and explain the reason why if it happens to be a large margin.

How are pyrolysis and I.C.E. different from one another? Pyrolysis produces energy from solid materials while internal combustion engines require liquid fuel. Fuel is produced when a specific substance reacts with the environment, specifically carbon. Vibrational concerns in the environment and energy conversion systems

According to Mr. DAI, Tesla had the idea that electricity could be distributed wirelessly. He also said that in order to understand physics, we primarily need to understand energy and frequency.

Prof. ADI adds. Some people transform garbage into something considerably more useful. For instance, his doctoral student converted plastic waste into gasoline. This functions by dissolving an object's carbon chain molecule (in this case plastic). Later on, he goes on to say that education's main goal is to help people recognize the value of everything around them. The big question is "why is there so much rubbish all around us?" as the subject of waste separation continues. The topic of how we may manage waste more easily is then brought up in the conversation.

Desalination -> the process of cleaning water from sea water to become drinking water. By filtration and using graphene (carbon compound). Pyrolysis produces charchoal / biocharcoal. Charcoal is produced from heated wood / coconut shells, while biochar is produced from biomass such as crop residue, wood chips, etc. Heated at a lower temperature than charcoal but with a longer duration. Charcoal is commonly used for fuel / energy sources, biochar for soil amendment.
