Every once and awhile, there are "major breakthroughs" in nuclear fusion (the last being in December 2022), and misleading news articles are quick to make it look as though scientists have finally achieved a "net energy gain". However, it's only a net gain relative to ''some'' of the energy inputs, not the whole system in total. In other worse, fusion is not a viable power source yet. We don't know how long it will take to be. Since [[climate change]] is already near a [[tipping point]], we need to explore other solutions besides fusion. | |||
