Al Fin and I disagree on a great many things, but his coverage of Brian Wang’s story about small scale nuclear fusion is worthy of note.
By far the single greatest problem we face as a civilization is energy. Nearly every other challenge derives from the bad solutions currently providing this vital commodity, from the geopolitics associated with acquiring its fuels, from the exhaust from burning those fuels, or from energy’s cost in economic terms.
When energy production is ecologically harmless, ubiquitous, cheap, and cannot be controlled by any single entity, our human civilization will finally begin to be free. We will require huge amounts of energy to achieve this freedom, but solving its production is the first step.
