> The system uses a net of lasers surrounding the beam to detect obstructions, like a bird or person, and it automatically shuts off transmission until the obstruction has moved on.

The sensor + electronics part is what is different today from what Nikola Tesla could do.

But the ISM band usage might suck for anyone who needs high SNR for other use, because the scattering on moisture + a 1kw/sqm power delivery means it will look like shining a laser through a dusty room.
