Does it really need to be cheaper if it's more promising?

promising what?

It needs to promise to eventually be cheaper, or otherwise better in some niche.

I can imagine it being useful for spaceships, for example.

But I can't see it ever being cheaper than eg solar, without some kind of breakthrough, like cold-fusion.
