This is a lowpoly version; have a look at the other one if you have a fast computer and if you want to see all the details.
A communication satellite built with 19th century technology. Because electron tubes or integrated circurits (to amplify an electric signal) are quite difficult to built with the available material, I decided to build a optical system. A large dish and some mirrors reflect the incoming light pulses from a ground station to a ruby crystal. So the incoming light both triggers and pumps the ruby, the light is therefore amplified by stimulated emission of radiation. Because the amplification is too weak, I added an undulator. This one is powered by a simple steam engine. The fluid in the tubes outside the housing expands (-->steam) in the 4 solar panels, then runs through the steam turbine (wich powers the generator) and cools down in the condenser...
