Re: 2) it's already working, it's just the energy in isn't less than the energy out yet (but it's constantly getting better).
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.
I 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.
