I was under the impression that fusion is held back by two major things.
1.) cost. It's incredibly expensive
2.) speculation. We don't _really_ know if it'll work yet.

Harnessing fossil fuels for cheap energy was so revolutionary that it's necessary for almost all aspects of our life. It would be great to do that with hydrogen too.
- gph 10y agoI get what your saying, but I wouldn't consider something to be working if it requires more energy in than it produces. It's not like people are questioning whether we could ever produce a fusion reaction. We're questioning whether it's actually viable as an energy source.
- bduerst 10y ago"Not efficient" is a far cry from being "speculative", though.
