Artificial photosynthesis is being researched as a way to convert solar energy into fuels by mimicking the process of photosynthesis in plants. The document describes artificial leaf, which is a device that uses sunlight and inexpensive, earth-abundant materials like silicon, cobalt and nickel to generate streams of oxygen and hydrogen gas bubbles when placed in water, similar to a natural leaf. The gases can be collected and stored for later use as fuel. The document outlines the construction, working, fabrication process and potential applications and advantages of artificial leaf as an alternative energy source.
Artificial photosynthesis aims to replicate the natural process of photosynthesis through chemical reactions. It uses sunlight, water and carbon dioxide to produce carbohydrates or solar fuels like methanol, methane or carbon monoxide. These solar fuels could serve as carbon-neutral, renewable alternatives to fossil fuels. However, current catalysts are not efficient enough to reduce CO2 into fuels at useful rates and selectivities. If developed further, artificial photosynthesis on an industrial scale could help solve global warming by reducing atmospheric CO2 levels.

Yaseen Sofi RENEWABLE AND NON RENEWABLE SOURCES OF ENERGYAyaan Sofi
The document summarizes renewable and non-renewable sources of energy. It discusses various renewable sources like solar, wind, hydroelectric, geothermal, biomass and biofuels that are naturally replenished. It also covers non-renewable sources like coal, oil, natural gas and nuclear energy which will run out over time. The document highlights advantages like abundance and disadvantages like pollution for both renewable and non-renewable sources of energy.
Renewable energy and nuclear power both have advantages and disadvantages as energy sources. Renewable sources like solar and wind are better for the environment as they produce little to no emissions. However, they are intermittent sources that only work when the sun is shining or wind is blowing. Nuclear power produces very low emissions compared to fossil fuels but poses challenges with long term waste storage and safety issues that make it costly. The debate around these energy sources is complex with reasonable arguments on both sides.
This lesson plan discusses 10 sources of energy: solar, wind, geothermal, hydrogen, tidal, wave, hydroelectric, biomass, nuclear, and fossil fuels. The objectives are for students to justify their choice of most reliable energy source and explain the importance of conserving energy. Students will group according to their preferred energy source, debate the efficiency and convenience of different options, and research pros and cons of the 10 sources in an assignment. While each source has benefits, all have flaws, so a balanced approach using multiple sources is needed.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
