The problem of producing energetic macrons (macroscopic particles)

Macrons are defined as macroscopic particles (e.g. dust particles). If methods of acceleration can be discovered for producing energetic macrons then a new field of macron physics will emerge. A few possibilities are briefly mentioned, in particular the possibility of controlled thermonuclear power. Some speculative ideas on macron-beam interactions, such as rocket propulsion in a neutral beam and ramrod acceleration in a charged beam, are discussed as possible means for attaining energies higher than have been previously achieved.
