How Does Compressed Air Energy Storage Work?

This energy storage system functions by utilizing electricity to compress air during off-peak hours, which is then stored in underground caverns. When energy demand is elevated during the peak hours, the stored compressed air is released, expanding and passing through a turbine to generate electricity.

The five basic principles of video compression

Principle #1: Predictable and redundant data can be compressed more. Guessing how information will be distributed is the backbone of many compression algorithms. If you can predict repeating patterns - for example letters or words if you''re compressing text - you can more efficiently store the data. This is also true for redundant
