Energy storage technologies: how to store energy?
Let''s see how we store energy in the 21st century. Renewable energy storage solutions. It is much harder to store renewable energy than fossil fuels. Non-renewable energy only needs some ''space'' to be stored, but green energy is stored in batteries, electric capacitors, magnetic storages – that have a lower efficiency.

Pneumatics 101: Basics of Pneumatic Systems
Pneumatic energy is the power generated from placing a large volume of air within a relatively small area. As the molecules are pressed together, the resulting pressure travels through the system and cause the main motor or actuator to rotate, which in turn powers the machine. This continues until the operator switches the machine off.
