A major achievement for design engineers is building precise control mechanisms for active processes. Lives depend on the precision in which certain processes are maintained, such as the manufacture of drugs.

Plants use biological systems that harvest light energy from the sun to convert environmental water and carbon dioxide into tiny carbon/hydrogen energy units stored within them.
