From my math undergrad, I feel like generally there are two feelings on this kind of thing:

- No practical application is needed, since studying math is an end in itself

- If there is a practical application, it should be fairly obvious and the author should not have to stoop to the level of trying to enumerate them

I'm not saying I agree, but I think there is part of the math community that doesn't care to enumerate practical applications. Expecting this kind of thing from this area of research may be an uphill battle.

Sure, but geometric algebra is specifically marketed as a unifying framework that makes geometric problems easier to reason about. It's not something you learn to solve previously unsolvable problems. So why is there a distinct lack of down-to-earth problem solving?

I think one would have to have a background in modern algebra and physics to see where the "unification" is useful. Then it becomes a lot more obvious, for example Maxwell's equations can be compressed down to one equation with this type of algebra.

In any case, check section 10 for another application for physics.
