Harry's force rings

[RobReece]

How does this work with his staff? He carved the spell on the end of his staff multiple times and used it against Asher in Skin Game. Harry is moving the staff, but the actual spell is not touching him directly (ie ring on skin). I could buy the argument that Harry is necessary for the rings to power up. We only saw the rings "being charged" while he was wearing them within his aura. The staff is a different story. The carved spell on the end of his staff is not within his aura. Is it charged by passive movement (just being used as a walking stick)? Does Harry have to run energy through his staff with movement to charge the spell? When it comes to the staff, it seems inefficient to have to actively run energy to it in order to charge it.

I think it would be the same as the rings, so long as he's manipulating the staff, it draws energy from him and stores it in the end of the staff. 
My question would be, the 76 layers (iirc), do you nave to fill them one at a time, layer 1, then layer 2, etc. Or do you think they're filling simultaneously? I think that make it pretty strenuous just moving it around,  at least until they were filled and no longer sapping the extra energy.

How about this, strap it to the top of a SpaceX rocket. It doesn't seem like it interferes with technology. So everyone should be safe.

If all it needed was for the rings to be moving then he could have been doing that for years ...

By his own admission, sometimes Harry misses some obvious-in-retrospect things.

Remember:  he was trained by centuries-old old-school wizards who were trained by even older ones.  Ancient traditions (that are really silly) are frequently perpetuated in such thought-bubble environments.

Add to that the reluctance to work with mortal technology and to use helpers (the Guard or Mister as examples) and it becomes easy for Harry to miss obvious solutions that are clear to us outsiders.

I still think that Harry made them, Harry enchanted them, Harry uses them, Harry has to supply the energy that fills them.

Harry says it's just storing up force... and
"F=ma"
At the end of the day, I really think this is magic "doing business with physics."

Elaine (with largely the same training) literally just plugs her similar-use elecric-attack gadget into the nearest wall-socket to recharge it.

And I think it's like his other magics where the energy come from Harry, albeit more efficient than most as he's made these rings a few times, improving them each time.

I guess we'll have to agree to disagree
