Our project aims to design an automated room temperature controlling system using a heater, fan and a curtain where the power is provided by a renewable energy source, solar energy. This system will keep the temperature of a living space at a desired value without human intervention. An Arduino kit along with additional materials and components such as 3D printed fan and a solar panel are used in the project. When the temperature is higher than the desired temperature, the fan will turn on and the curtains will close, whereas, if the temperature is lower than the required temperature, the heater will turn on and the curtain will open. In the future, this concept can be expanded to build bigger projects such as a house, where the temperature setting in the entire house is constant and automated using a solar power, thus benefiting the environment.

Clothes dryers are one of the most common products amongst household appliances. Around 18.4% of the total of residential energy use is used by dryers. Considering their high energy consumption, the current project proposes to design a prototype of a dryer with reduced electrical energy consumption. This project, called “The Breeze Clothes Dryer”, has a design consisting of two main systems: heating liquid system and air flow system. This design makes use of a solar energy collector to complement the heating system of the traditional drying machine. This energy collector heats the water inside a copper tube, after which the hot water is moved to a radiator with the aid of a pump. Simultaneously, the air flow system starts with the room air entering into the system, after which a fan blows the air passing through the radiator, where the air is heated up. Once the air is hot, it is transported through tubes to reach a chamber with wet clothes to be dried. Finally, a second radiator receives all the moist air, which cools it down to become water droplets, which are then released into the environment. The medium to provide cooling is the room air which gets pre-heated in the process.
Using an electrically powered air conditioner to adjust the temperature during sleeping uses too much electricity. To improve the energy efficiency of this need for comfort, we design an auto thermoregulation bed which is powered by solar energy. Solar energy is a better choice to generate the electricity that the air conditioner use in the night. Also, solar energy won’t emit carbon dioxide during this process. The system will also have ability to both heat and cool.
Refrigerators are one of the household appliances that consumes the most electricity. In some places of the world, the cold climate predominates. These climates may even go below a refrigerator average temperature (near 0 degrees Celsius). However, even when the outside environment weather drops below the refrigerator temperature, this household appliance will keep running without making any efficient use of the outside temperature. This project aims to design a refrigeration system that reduces the energy consumption of this household appliance. The system relies on the thermal conduction principle. The system takes advantage of cold weather conditions when it is possible. This system makes use of a coolant liquid, a water pump, two temperature sensors, an Arduino, a coolant metal storage, PVC tubes, and copper tubing. The coolant is chilled by the external environment when it is colder than the desired temperature in the refrigerator and circulated through a heat exchanger inside the refrigerator to keep it cool.
This project aims to design a solar and kinetic charged power backpack for providing power to the Apple Laptops and phones. The purpose of the renewable-charged backpack is to provide a portable and easy alternative for charging phones and laptops. The backpack should be a benefit to present and future device owners to assist in their daily activities.
Many people are used to leaving the lights on when they are away for a long time or temporarily, which means waste of electricity. For engineers, one of the main responsibilities is to improve product efficiency to save energy. With regard to “improving efficiency”, an important way to archive this goal is to prevent the waste of electricity. Therefore, this project is to make a smart light (table lamp) which can save power by detecting human body heat: it can automatically illuminate when users sit close to the lamp, and turn off when they’re away. The main objective of our project is to design an energy-saving table lamp, which can detect human body heat, so that it will not waste electricity when owners are not using it.
Nowadays, the impending scarcity of energy has become a serious problem. However, there is still an enormous amount of energy waste in daily life. For example, most of the teaching areas must be lit at night for the sake of safety. The aim of this project is to design a ceiling light that can adjust its brightness automatically depending on whether buildings are empty. Additionally, it is also expected to change the direction of the lighting automatically to improve the energy efficiency and maximize the light usage as well as the user’s convenience.
Due to their ability to cool the human body, fans are an important item in daily life. This project aims to design an innovative temperature and location sensitive fan with a high level of energy efficiency. The design is a typical fan powered by a USB cable modified by aiding it with temperature sensors to detect the location of the hottest spot in a space and additional motors to rotate and point the fan towards the selected space. This system is controlled by Arduino and comprises other components.
This project is a light tracking system. In modern society, electricity is widely used in our daily life for illumination. However, substantial amounts of electricity are wasted daily, especially in residential homes. This light tracking system is designed for cases when there is a large room but only few people require light. Based on our observation, the efficiency of light, especially in public areas is relatively low. If all the lights in a room are on for only one or two people, it is a waste of electrical energy. Therefore, instead of lighting the whole room, only the person’s location should be lit by a spotlight. This can save energy.
Nowadays, ships and boats are popular transportation for people to travel around. However, the huge consumption of fuel and pollution through fuel leakage are considered as two significant concerns of normal ships and boats. In addition, because of the limitations related to the hull shape, there is still much room for the energy efficiency of normal boats and ships to improve. The objective of this project is to build a remote-control model boat that uses new materials and has a well-designed shape to minimize the resistance of water so that the energy efficiency will be maximized.
