Educational tools

Small, local sketches you can drive with a slider. They teach Earth ideas. They do not run Concordia.

Classroom, not operations

Client-side educational models only. No backend, no tracking beyond ordinary page analytics, no invented live city control. Concordia does not run these simulators in play.

What these are

The Museum keeps three widgets that run in the browser, on this site’s JavaScript, with no city to command. They belong beside Mathematics and Power the way a terminal might offer a moving diagram next to a plate. They are not twins of a building, not Caregiver interfaces, and not a preview of HUD systems.

Prefer reduced motion? The crowd sketch starts paused when the browser asks for less animation; press Play if you want the particles to walk. All three tools keep labels on the controls and a text status where numbers change.

Power balance

Full caption and fusion warning: Power balance.

Educational sketch · 21st-century planning numbers · not Concordia operations

Power balance

A toy load-versus-generation mix. Compact fusion is a planning sketch, not a working Earth plant. Building-integrated photovoltaics and piezoelectric floors exist as 2020s products and demos; city-scale yields here are invented for the slider. This is not a live city controller, and Concordia does not run this panel.

Crowd flow

Crowd flow

Dots are particles with a desired velocity toward the door, plus repulsion from walls, neighbors, and an optional pillar. Raising density or removing the pillar often builds a pressure arch at the gap — a published result in pedestrian dynamics, not a recipe for Concordia bulkheads. Prefer reduced motion? The sketch stays paused until you press Play.

Resource tokens

When a closed loop produces less water, power, or food, this toy raises a “credit price” and lets demand fall. It is reverse game theory as a classroom slider — not Ledger, not coinage, not a play economy, and not how Concordia rations anything in 2490.

Hard nots

  • Not Concordia operations, not Section 0, not Opening logistics.
  • Not ASI, not a twin of the city, not a communications protocol wearing a civic name.
  • Not a campaign override, bulkhead, or triage trainer.
  • Numbers are invented for the slider unless a caption points at a dated Earth source.
