Global Environmental Impacts and Sustainable Solutions
Nuclear Fusion Technology
Nuclear fusion is a process where the fusion (union of atomic cores) releases heat, which is used to vaporize water, moving turbines and generating electric current.
- Advantages: Necessary raw materials are practically inexhaustible, and the process does not generate radioactive waste.
- Disadvantages: So far, scientists have not been successful in controlling the nuclear fusion process for sustained energy production.

Solar Cooker Technology and Uses
A solar cooker is a device that uses sunlight as its sole energy source for cooking, baking, or pasteurizing food and water. It is a type of solar thermal collector that works by concentrating sunlight onto a receiver, usually a cooking pot. The cooker’s interior and pot are typically dark-colored to maximize heat absorption.
A transparent cover (like glass or plastic) and insulation trap the heat inside, creating a “greenhouse effect”

- Major Reservoirs: Biosphere, Hydrosphere, Atmosphere, Geosphere.
Lecture 3: Radioactive Decay and Half-Life
- Half-Life: A constant amount of time it takes for half of the radioactive atoms in a sample to decay.
Lecture 4: Mantle Plumes and Volcanism
- Mantle Plumes: Places where there has been continuous volcanism for a long period of time. They do not move, but tectonic plates move over them.

Urban Evolution: Pre-Industrial City, Renewal, and Ensanche
The Pre-Industrial City: The Old Town
The pre-industrial city, or old town, is the urbanized core dating from the city’s origin until the beginning of industrialization (mid-19th century). It occupies a small surface area relative to the current city and holds great cultural value.
Transformations During the Industrial Era (19th Century to Mid-1960s)
The pre-industrial city underwent notable modifications resulting from industrialization between the 19th century and the mid-1960s. These transformations
