One Large Plant vs Many Small
A single giant reactor can't scale or fall in cost; a fleet of compact, repeatable units can. Kronos designs MetroVolt as a manufacturable product, not a megaproject.
- One giant
- Bespoke, slow, no learning curve
- Many small
- Repeatable, faster, cost falls with volume
- Kronos
- Compact, manufacturable unit
- Effect
- Wright's-law cost decline
There are two philosophies for deploying fusion: build one enormous reactor, or manufacture many compact ones. The distinction decides whether fusion can ever scale and get cheap.
| Dimension | Many small / One large |
|---|---|
| Build model | Repeatable product / bespoke megaproject |
| Cost trajectory | Falls with volume (Wright's law) / no learning curve |
| Deployment speed | Faster, parallel / slow, serial |
A one-off giant produces no learning curve and can't be replicated at climate-relevant scale. A fleet of compact, similar units gets cheaper every time one is built — the dynamic that scaled solar and batteries. Kronos designs MetroVolt as exactly that manufacturable unit, deployed in three-unit stations, so cost falls via Wright's law. See compact vs conventional fusion.
