Commercial Fusion "Zero Marginal Cost" Ruin.

Diagnoses the grid chaos caused by achieving limitless Commercial Fusion: When baseload electricity approaches an absolute marginal cost of $0.00, energy markets collapse, destroying the business models of solar, wind, and the grid itself.

## The Myth of Free Energy

Sci-Fi authors promise that Commercial Nuclear Fusion will usher in a Post-Scarcity Utopia where electricity is "too cheap to meter." You will be able to run giant AI clusters and desalinate the oceans for pennies. This demonstrates a deep misunderstanding of Utilities.

### FAQ

**Q: If fusion power fuel is just seawater, why won't my electric bill be zero?**
A: The Delivery Monopoly. Building a magnetic confinement Tokamak that sustains a star on Earth costs $15 Billion. The "marginal" cost of the hydrogen isotope fuel is indeed effectively $0.00. However, the energy company has to borrow $15 Billion from Wall Street to build the reactor. 90% of the "cost" of fusion electricity is just the interest payments to Chase Bank and Goldman Sachs. Furthermore, even if the plant generated electricity completely for free, you cannot teleport electricity. You must push it through thousands of miles of high-voltage transmission lines, transformers, and local copper wiring. Maintaining that grid—paying guys in bucket trucks to trim trees off wires during thunderstorms—makes up more than 50% of your power bill. Fusion solves the Carbon problem; it does not solve the Grid Maintenance problem.
