PowerForge — an energy world of solar, wind and power grids

PowerForge

Meet the cast who each embody one piece of energy — then engineer a grid with them. Balance solar, wind, and nuclear against real demand, trace energy through every conversion, and keep a whole city powered.

Balance the grid Wire a circuit
Level 1

Start here

Grid Balancer Allocate solar, wind, hydro, nuclear & gas to meet demand — hit clean-energy goals without a brownout. Day-Cycle Grid Keep a city powered dawn to night as the sun, wind, and demand shift — then see your whole-day cost & carbon. Circuit Lab Wire bulbs in series or parallel and predict current, power & brightness — Ohm’s law hands-on. PowerForge Journey A path through every kit — clear each stop of real practice, then move on.
Brain Break Take a quiet moment between builds — a fun riddle or a short breather. Brain breaks help you remember what you learn.

All activities

Engineer & investigate

Grid Balancer Match supply to real demand exactly — watch the supply, cost, and CO₂ meters as you hit clean-energy goals. Day-Cycle Grid Re-balance the same grid across a full day — dawn, midday sun, evening peak. Energy-Conversion Chain Trace energy from source to use and see where it slips away as waste heat — never lost, only converted. Energy Ramp Release a cart and watch potential energy become motion — predict the speed and where the energy goes. Where Does the Energy Go? Old bulb 10%, LED 40%, motor 90% — predict which wastes the most, then see the useful/waste split. Circuit Lab Series or parallel — predict current, power, and brightness before the meters reveal it. Teach the Cast Teach an energy idea to a cast member still learning it — teaching makes it stick.

Practice & play

Concept Kits 16 kits · 400 questions from forms of energy to the grid, renewables & nuclear — a hint after a first miss. Mixed Practice A short round across the kits you have played — brought back to make it stick. PowerForge Sprint Race your OWN best on what you already know. Timer optional, no penalty for a miss. Trick Questions Brain-teasers with a twist — spot why the obvious answer is a trap. PowerForge Duel 2–4 players take turns on one device — same questions, highest first-try score wins. Or open an online room. Progress Your levels, days active, and how each skill area is coming along — saved on this device. Progress report For grown-ups — a private on-device snapshot mapped to the skill areas. Export a CSV or print.

Same idea, another world

Something you practice here shows up somewhere else too — that's real learning that travels.

Height turning into speed on a ramp is energy being conserved — the same trade a machine makes when it swaps force for distance. The shared idea: conservation of energy — energy is never lost, only traded (height becomes speed as potential energy turns into kinetic), the same bookkeeping as a machine that trades force for distance Try MachineForge →
