If the planet has any appreciable amount of tilt, you will want to align the swarm's 'Longitude of (AN)' with the planet's summer solstice on the northern hemisphere, so that the pole switchover happens properly. Then set up two Ejector stations on each pole each will be active for half the year. With a polar swarm orbit, make sure the radius is large enough so that you can always have a 5° pitch angle from the poles. Putting them on the equator gives a gap during noon when the angle is too high, while going farther towards the poles reduces the percentage uptime. If you are shooting into a near-equatorial orbit, Ejectors are optimally positioned around 30° latitude - this gives them the maximum uptime across the day, starting at a 5° angle near dawn, reaching a maximum 60° angle at noon and then decreasing again. If the swarm has a polar orbit (90° inclination), then the target will always be one of the poles above or below the system, switching every half-year.īecause of these limitations, it is basically impossible for a single EM-Rail Ejector to have 100% uptime, or even more than 50% when averaged over a year. That would completely undo the discreetly careful placement of the unfortunately necessary trilogy of Silos. orbit-forward) from the line intersecting the planet, the sun and the swarm's orbit. I like to tuck them out of sight by the hardwood stumps under the tree overhang. This means that for swarm orbits on the ecliptic plane (0° inclination), the target will be 90° counter-clockwise (i.e. You can definitely place the silos anywhere on the forest map. The target point selected is the cross-product of the up-vector of the swarm's orbit with the vector from the sun to the Ejector. The Ejector will then track a point on that orbit and be eligible to fire Sails if the pitch angle is between 5° and 60°. In order to fire, you must select a specific Swarm orbit to target in the UI. The Ejector also can't be built nearby other tall buildings. The EM-Rail Ejector is a railgun-type launcher that shoots Solar Sails in a straight line at high speed, but the planet the building is on will prevent firing. Because of this, low-value high-yield crops like Corn or Tomatoes are more valuable in the preserves jar. The Silo is a type of farm building purchasable from Robin at the Carpenters Shop. The Preserves Jar increases the profit of a crop using the following equation: (2 × Base Crop Value + 50), while the Keg multiplies the base value of Fruits by 3, and most Vegetables by 2.25.

This building is comparable with the Vertical Launching Silo that launches Small Carrier Rockets. Build materials: Stone (100) Clay (10) Copper Bar (5) Size: 3x3. Because the ejector shoots with direct line-of-sight to a point on the swarm's orbit, and it can be blocked by the planet, some thought should go into placing them. The EM-Rail Ejector is used to launch Solar Sails into orbit, either as part of a Dyson Swarm or to form the Dyson Sphere.
