- Depending on the reaction chamber and throat material and conditions, it
- might be possible to use ultrasonics to break the aluminum into fine
- droplets.

- Hmmm, I vaguely that there are ways to make ultrasonic "whistles". I don't
- know if this could be applied to the injection system, but if it could, it
- would at least not require an electrical power source. It does sound complex
- though; hopefully existing injection technology will produce droplets of
- sufficiently small size.
-
- I wonder if acoustical energy can somehow be used to protect the surfaces
- from accumulation of aluminum oxide?
