Crystal Solar Tower
The crystal solar tower evolved gradually from the honeycomb crystal. It became taller and taller. Within time, they would grow to titanic proportions take to their hollow core, strong crystalline structure, and the other benefits of being huge. Its hollow core worked as a ventilation system. During the day, the hot air would rise in the crystal-like plant, helping circulation, in a manner similar to Earth's termite mounts. During the night, the process would reverse. This semi-passive breathing is a great benefit for the crystal solar tower. It can regulate this to a small extent by slowly changing its own color to prevent overheating, so on really hot days it would turn a silver-like color. The wind would also carry it spores, which would be released at the top, very far. The root system of the crystal solar tower would be equally impressing to the central tower. Stretching far and wide, this low covering would trap hot air during the day and channel it towards the tower, while at night the process would reverse. The roots also prevent other solar towers from growing too close, but does not prevent other life from surviving in the area.
