Characteristics Of Sound

Sound in brief but remarkeable terms is a vibration, that our ears percieve by the sense of hearing. Most commonly vibrations travel to our ears via the air. The ear then converts these sound waves into nerve impulses that are sent to our brains, where the impulses become sound.

Alternative Energy And The Need For A Proper Storage Technology

A number of energy storage technologies have been developed or are under development for electric power applications, including: * Pumped hydropower * Compressed air energy storage (CAES) * Batteries * Flywheels * Superconducting magnetic energy storage (SMES) * Super-capacitors This is the future that we can safely anticipate, especially when there is a rapid depletion of other energy resources. Of course, the most important energy resource still remains the sun from where we can derive solar power and fulfill various energy and power requirements. Off late, many companies have started to build mono-crystalline and polycrystalline solar cells, which can be used in several sectors like aerospace, the aviation industry, residential… Read More
