However, Part II introduced a new gadget that replaced the flux capacitor’s need for plutonium as a power source.

The Mr. Fusion Home Energy Reactor combusted organic waste and garbage to generate cold fusion. This powered the time-traveling flux capacitor and hover capabilities, but not the classic gas-powered vehicle. Mr. Fusion would solve serious energy and waste problems if scientists developed it in the real world.

13 The What-If Machine Could Explore Hypothetical Scenarios
