Harnessing Solar Energy: Methods, Applications, and Components
Introduction to Solar Energy
Traditional energy production systems and electricity generation pose challenges, making it necessary for society to develop alternative energy sources.
The Need for Alternatives
- Hydraulic power: The greenhouse effect and climate change are leading to more prolonged droughts.
- Fossil fuel power stations: These rely on a limited resource that will eventually be depleted.
- Nuclear power plants: These present the problem of waste disposal and the risk of nuclear accidents.

Disc Brake Inspection and Maintenance
1. Operation Check: Verify disc brake operation by observing the pedal displacement and caliper movement. If the caliper does not move correctly, remove it and repair it. Ensure there are no fluid leaks in the actuator or the hose connection. Check the condition of the disc and pads. Replace them if they are defective.
2. Brake Pad Thickness: The brake pad thickness should be superior to 2mm. When some pads are defective, all pads on the same axle must be replaced.

Electric Power Networks
Production Subsystem
This subsystem includes all electric power generating plants. Electric power generally requires a country.
Transport Subsystem
This subsystem starts at the substations lifting power plants and reaches down transformer stations through transmission lines (MAT Transport and AT).
Distribution Subsystem
This subsystem consists of primary distribution networks.
- BT = 230/400 V
- MT = 20000 V
- AT = 30000/66000 V
- MAT = 132000/420000 V
Mains
All elements and drivers are designed

Thermal machines convert thermal energy into mechanical energy, or vice versa.
Heat Engines
A heat engine transforms thermal energy (heat) into mechanical energy.
Types of Thermal Machines
External Fuel Sources
- Steam Engine
- Steam Turbines (rotary)
Internal Fuel Sources
- Spark Ignition (Otto cycle)
- Compression Ignition (Diesel cycle)
- Open Cycle Gas Turbines (rotary)
- Wankel Engine

- Apse: A semi-circular, domed chapel that stands at the head of a temple.
- Arch: A curved structure that serves to bridge a gap between two walls or pillars.
- Transverse Arch/Ribs: These serve to support a barrel vault, reinforcing it and dividing it into segments or sectors.

Secondary Memory
Secondary memory is a storage location other than the main memory. It can store and retrieve all types of information when needed without having to keep it in the main memory.
Kilobyte
A kilobyte is 1024 bytes.
Operating System
The operating system is the set of programs or software installed on your computer to control the operation of all physical devices connected to it, as well as all application programs.
