A minimalistic setup for autonomous radar stations with 100% terrain coverage and zero downtime.
- 1 radar
- 1 solar panel
- 1 accumulator
- 1 power switch
- 2 arithmetic combinators
- 2 power poles
Normally, to maintain a radar fully powered throughout the night, you would need approximately 7-8 solar panels and 6-7 accumulators (downscaling from the 25:21 ratio for stable 1MW power supply). However radar doesn't need to stay powered permanently - revealed map chunks will stay revealed for some time even if nothing is scanning them anymore. This setup will only activate the radar for short periods of time and then disconnect it for awhile, exploiting this feature.
Resulting radar power consumption is thus equivalent to ~33kW, allowing a single solar panel and a single accumulator to power a radar and keep the map revealed 100% of the time.
Same trick can be applied to grid-powered radars to reduce their power consumption if that is a problem for your base. Accumulator and solar panel can be removed, everything else should stay the same. Only the rightmost power pole must be connected to the grid, otherwise radar will stay on 100% of the time.
1. Drive a car around the map, placing these wherever you wish. They are fully autonomous, so no need to connect them to anything, and will keep your map under constant observation.
2. Save on radar energy costs for your main base or outpost.
3. Small power poles that remain from the early stages of your base are finally useful! Sure, the setup can be made with mediums, but either it will be larger as a result, or it will need manual cable disconnecting. So this is a place where small poles are actually better than the others.
1. Note that the map chunks highlighted by this setup will do a lot of flickering. If that annoys you, add a second solar panel and modify the "R = R % 480" combinator to "R = R % 300". This will disable the flickering and increase power consumption to ~45 kW, making a single solar panel insufficient. A single accumulator should still be enough.
2. Due to extremely short time that the radar stays on, terrain exploration beyond radar's scanning range will be glacially slow.
