Not really, because the power is not super concentrated. The power is flowing through an area of a few m2, so it's less power per unit area than a sunny day, though on a similar order of magnitude, and that's assuming the microwaves are perfectly absorbed (the frequency of microwaves used is one where water is much more transparent than the one in microwave ovens). In the video they claim the beam is safe for people and animals to pass through (based on current standards for RF exposure). This is comparison to e.g. lasers where even if the power density is the same the fact that it's concentrated in a few mm2 makes it a lot more dangerous.
