Extraterrestrial Nanolaser Transceivers
Fire self-aligning nano-lasers at near the speed of light to create a 'fiber optic' channel reaching to nearby another star.
Today, nanolasers are small, like 35nm each (see link). As a receiver, put a photo-sensor of the same size. Attach a battery and counterweight with a tiny computer to adjust directions. Envelope in omnidirectional photosensor matrix. Test. Mass produce. Create a linear magnetic accelerator in space. Release. Use as a communication channel for any miro-sized probe travelling in parallel. Enjoy hi-res pictures of planets nearby another star.

This idea should be under a goal of reaching other star systems, under space travel category.
Интересный. Могут ли эти трансиверы быть применены для очень дешевых коммуникаций на земле? Маленькие лазеры дешевы. {0,5}
Я думаю, что нанотрансиверы также могут иметь особую конструкцию, чтобы информация могла передаваться, например, посредством поляризации света, чтобы вычисления могли выполняться внутри SENT, как если бы они были одной машиной Тьюринга.
Interesting. Could these transceivers be also applied for very cheap communications on earth? Small lasers are cheap. {0.5}
I think, the nano-transceivers could also have a specific design, so that the information could be transferred, e.g., via light polarization, so that the computing could be performed within SENTs as if they were a single Turing-machine.
