Needs power
Cooks on a gas flame. Responds instantly and keeps working when the power is out, which is the one resilience argument in its favour; against it, burning gas indoors puts combustion products into the room, so it wants real ventilation above it.
One of 9 ways to meet Cooking energy supply. Build 2/9, Upkeep 5/9, Efficiency not rated. Cost, carbon and footprint below are rated against those 9, not in absolute terms.
A gas supply or room for a bottle, and extraction above the hob: this is the one appliance in the house that burns fuel in the room people are standing in
Every option in this sub-function, with the value on each axis and a note on what drives it (this solution highlighted):
| Solution | Build skill | Upkeep burden | Efficiency |
|---|---|---|---|
| Wood cookstove | Basic | 5 | #3 |
| Solar cooker | Basic | 3 | #4 |
| Rocket stove cooker | Basic | 5 | #2 |
| Household anaerobic biodigester (biogas cooking fuel) | Basic | 3 | #3 |
| Induction cooktop | Basic | 5 | #1 |
| Haybox / retained-heat cooker (fireless cooker) | Basic | 1 | N/A |
| Micro-gasifier (TLUD) cookstove | Basic | 3 | #2 |
| Solar-powered insulated electric oven | Basic | 2 | #3 |
| Gas hob / cooker | Specialist | 6 | N/A |
Build skill and upkeep burden are proxies (lower burden = simpler to maintain); the efficiency column is this sub-function’s ranking, 1 = best. “N/A” where an axis isn’t rated here.

No sizing or quantities: how much a technique yields, and how much a household needs, both depend on the build and the people, so the catalogue compares options rather than dimensioning them. It carries no bill of materials and no build sequence, and it is written for an oceanic, clay-soil climate (Normandy, France). Regulatory notes are indicative and need confirming locally.
