miclonization chamber
A fictional device from the MACROSS science fiction series. It appeared in the first TV series from the 80s and has been featured in most productions to this day.
The miclonization chamber is a sophisticated device that uses "super-dimension" (hyperspace) energy that allows the alien Zentradi "maclone" giants to reduce their sizes to human levels. The technology on which these devices are based was created by the advanced Protoculture and has been long lost since milenia ago.
