Why is fusion ignored?

Because it is always 50 years out.

Why is the LENR ignored then?

Because at least regular fusion has significant and universally accepted empirical evidence of it even being fundamentally possible.

LENR has had to have a name change because the primary connotation with cold fusion is a bunch of psuedoscience and bullshit.

Yes, some real scientists have published some results that make continued study worthwhile, but if regular fusion is 50 years off, our indication is that LENR, if it's even possible, is 100.

Why 100? I see no barrier to adopt the LENR worldwide in a short period of time, when the effect will be well understood and easy to reproduce.

If all you want is fusion instead of energy production then just put a fusor[0] in your garage.

Lab results that show some evidence for trace amounts of fusion reactions do not imply net energy production. E.g. one of the recently announced results needed a powerful xray beamline to get some tiny results, which consumed more energy than the fusion reactions ever released.

This is comparable to the ancient greeks inventing a "steam engine"[1] that does no meaningful work.

Unlike fission and like thermal pump, this energy can be used to heat buildings, so even if nuclear reaction can produce just 100-200% of additional energy, which is enough for about 30-60% of electricity spent, the device still can perform at 200-300% efficiency when used as a home heater.

In that case it would compete with a heat pump. And unlike that one it can't double as AC.

And that's not exactly baseline power production. Shifting goalposts?
