This is incredibly idiotic. They purposefully filled the airwaves with garbage packets, to collect bare milliwatts. And the "camera" took a B&W photo at tiny resolution and sent it nowhere.
They even used already existing (and not even the best) energy harvesting chip. The only innovative thing here is somehow getting this to get posted on HN
Completely. And the claim that "this doesn't impact wifi bandwidth" completely violates the laws of physics. As if the 2.4GHz band isn't junk enough already with noise.
And nor is this novel. Tesla did a large public demonstration of this in 1899. The only difference was the frequency and the target device (light bulb).
