Any large scale terraforming project will need large scale electrical power. Sparky is the nickname given to SevenBot by his coworkers. This robot controls all the necessary turbine hardware to capture energy from the very large dust storms and tornado's on Mars called Sand Demons, and convert that energy into electrical power. Once the Shell World structure is complete however, other methods will need to be created as the storms will cease to exist.
All custom art pieces are sculpted using items found at flea markets and antique shops and are not meant to be toys. As such, you will find patina, scratches, and/or dents in the various materials. All of these imperfections add to the beauty and character of the final sculpture. The series of bots that fall under "MinBots" also have multi colored finishes applied to them.
