Even though most German speakers may understand what you mean when you say beamer instead of projector, native English speakers will typically be completely lost. * Evidence for the use of the word beamer for BMW cars and motorbikes can be found in the Oxford English Dictionary, see here. An alternative spelling is beemer. Moreover, as explained here, BMW enthusiasts use beamer/beemer for cars and beamer for motorbikes. (Thanks to Eric for the link.)
Mote refers to a small particle, as a bit of sawdust; beam refers to a glance, or eyebeam, formerly thought to be emitted from, rather than received by the eye. Shakespeare makes use of the allusion in Loveâs Laborâs Lost: You found his mote, the King your mote did see, But I a beam do find in each of three.
