A Space Colony is when a colony is not on the surface of a planet, but instead is a huge space station. They are discussed in detail here.. And when a mature colony starts making noices about "No Taxation Without Representation", the time is ripe for a War of Independence.
PhotoChemically Etched Screens are used in rotary screen applications such as fruit separators, sugar processing, micro electronics, and medical Celerons. Additional uses include hydraulic valve screens, fuel filters, and extruding screens, as well as particle separation and sizing.
