MRI: Magnetic Resonance Imaging (MRI) is useful for taking detailed images of the human body. This technique is useful for diagnosing diseases and disorders such as strokes, spinal cord injuries, tumors, multiple sclerosis, and internal eye or ear disorders. It helps doctors understand the structure and functioning of the brain. MRI has been useful in saving the lives of many individuals, thus promoting a healthy environment.
Hydrogen Fuel Cell: This technology is an alternative to fossil fuels. It is called a clean fuel. Electricity is generated by combining hydrogen and oxygen.
OTEC: Ocean Thermal Energy Conversion (OTEC) technology is used for generating electricity. This technology uses the ocean’s thermal energy to produce electricity. This technology is good for the environment as oceans thermal energy is a renewable source of energy.
