This document discusses dual axis solar tracking systems and spherical solar generators. It describes how dual axis trackers can rotate in both horizontal and vertical directions to always point at the sun, providing about 40% more power output than single axis trackers. A spherical sun generator prototype called the beta.ray is then presented as an innovative design that combines spherical geometry with dual axis tracking in a compact surface area to yield twice the output of a standard solar panel. The project aims to improve energy efficiency by 35% using a ball lens and specialized geometry within a fully rotational self-tracking device suitable for inclined installations.

Energy harvesting using nano leaves
Nano leaves could provide a solution to future energy crises by harnessing solar, thermal, and wind energy through biomimicry of plant leaves. They would consist of nano-photovoltaic, thermoelectric and piezoelectric cells embedded between conductive nano sheets to generate electricity from light, heat and motion like wind. A nano tree producing around 7,000 kWh per year could cost $12,000-$20,000 but last over 20 years, making it cost effective compared to other renewable energy sources. Nano leaves have applications in deserts, parks, and industrial areas to provide green energy and shade.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
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.

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

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

- 5. Why Solar Energy? Easily accessible. Energy harnessed is free of cost. Pollution FREE. Available in infinite quantity.
- 6. Single Axis Trackers: • A single axis tracker can pivot in only one plane – horizontal or vertical. The horizontal type is used in tropical regions where the sun gets very high at noon, but the days are short. The vertical type is used in high latitudes (such as in UK) where the sun does not get very high, but summer days can be very long. • Although the construction is less complicated it is also less effective in harnessing the total solar energy. Dual Axis Trackers: • Dual axis solar tracker has two degrees of freedom that act as axes of rotation. These axes are typically normal to one another. • It can rotate simultaneously in horizontal and vertical directions and are able to point at the sun at all times. Dual axis trackers track the sun both East to West and North to South for added power output (approx. 40% gain) and convenience.
- 7. Classification based on on the Driver type Active trackers use motors and gear trains to direct the tracker as commanded by a controller responding to the solar direction. Passive trackers use a low boiling point compressed gas fluid that is driven to one side or the other to cause the tracker to move in response to an imbalance. Open- loop trackers use no sensing but instead determine the position of the sun through pre- recorded data for a particular site. They rotate at regular time intervals. Solar Tracker
