The Nuclear Power Plant supplied virtually unlimited power to the megacity and its surrounding industries. At its heart was an inertial confinement nuclear fusion reactor, capable of initiating tens of millions of microbursts per second.
Each microburst released an immense amount of energy by fusing hydrogen isotope nuclei at temperatures in excess of 100 million degrees Celsius. This energy was captured and transformed into electricity by vast fields of magnetohydrodynamic generators.
Hydrogen fuel reserves were virtually inexhaustible, drawn from the vast ocean surrounding the city. Its technology made it possible to separate heavy isotopes such as deuterium and tritium from seawater.
The plant was continuously monitored by a super-intelligent artificial intelligence to ensure safe and optimal operation. Any catastrophic failure was virtually impossible thanks to state-of-the-art containment systems.
With nuclear power plants of this type scattered across the globe, the energy crisis that once plagued humanity had become a distant and forgotten memory. A new era of energy abundance had begun.
