Nuclear technology – the technology and application of the spontaneous and induced reactions of atomic nuclei. Wind energy – wind energy is the use of wind to provide the mechanical power through wind turbines to turn electric generators and traditionally to do other work, like milling or pumping.
These events impact Earth's upper atmosphere and can occasionally cause communications blackouts. Superflares, by contrast, are rare, higher-energy outbursts – potentially much more powerful ...
Since technology uses resources, technical history is tightly connected to economic history.
