I am going To add this to The Stars Beckon! but I thought it would be a good idea for Aurora. It is written up how it is going to be used in TSB! so you will need to come up with how it would work in Aurora.
SolettaA soletta is a gigantic mirror that can be built in orbit once Physics/Engineering tech level 8 has been reached. It can be built at a Lagrange Point or Geo-Stationary Orbit if the nation has built a (Star)port in a region. A space platform or station in orbit is required to support construction.
It can focus light either onto a planetary body (such as the Earth or Moon) or onto a Solar Power energy relay in the region it is stationed above. It can also be used as a ?sun shade? to reduce the colony cost, especially if placed in the Planetary-Stellar E1 Lagrange Point. Solettas are useful in terraforming Planetary bodies ? by either shading it from solar output or focusing additional light onto the Planet.
If a soletta is built from Planet-based industry and raw materials then it has its base cost doubled. If it is built from lunar or asteroid raw materials its cost is 1.5 times. If it is built from orbital industry and Lunar or asteroid raw materials the cost is normal ? because much of its materials utilize by-products of orbital manufacturing. When built and placed in orbit the function of the soletta must be determined. The function can be changed by an order and costing 5 WU.
? It can be used to increase the level of light affecting a planet. For each Soletta assigned and in the E1 Lagrange Point decrease the colony cost by .10.
? It can be used to enhance the industrial production of a single region by 15%. No more than one Soletta may be assigned to any region.
? It can be used to decrease the level of light affecting the planet if it is located in the Planetary E1 LaGrange Point. For each Soletta assigned reduce the colony cost by .10.
Multiple Solettas can be linked together to increase the size of the colony cost affect.
When built a Soletta can be given the Prefab Cap and that will allow it to be built on another planet or in another star system.
