Enclosures convert internal drives to portable USB devices. Prices range from $12 to $150 depending on type and speed. Most enclosures protect drives and dissipate heat
Chilled water systems provide cooling for medium and large buildings. Ancient Romans used water through walls for cooling. Willis Carrier invented first centrifugal chiller in 1926
Supercooling requires purified water, salt, clean glass/plastic cup, bowl, and ice. Glass must be clean to prevent crystallization. Bowl should be large enough to contain glass and ice. Add enough water for temperature measurement but not too much
