Nuclear fusion is far, far too expensive to provide energy “too cheap to meter” during upcoming decades. Not only is tritium (costing $30,000 per gram) necessary to start the initial reaction, reactors must be lined with expensive lithium. Equipment to make the tiny event happen is enormous, requiring space equal to three football fields. The complexity of the system requires twice as many employees – 1000 for fusion vs. 500 for a fission reactor. This helps explain why original cost projections of $6.3 billion mushroomed to DOE’s current estimate of $65 billion. More
