## Quote — verbatim

> At home, it's dual purpose, because I'm using solar to power my home, charge my car — and if I can use the same solar to power a data center, maybe a small home node or home data center, we have a dual purpose or multi-purpose solar, which is phenomenal. And your marginal cost of energy is zero at that point. That's what I meant by solving this energy crisis by going into the home.

## Context — site annotation, not spoken

Solar doesn't work at utility scale (batteries, transport) but is "great when it's dual or multi-purpose" — the economic core of his home-compute prediction.
