Looks nice, but there's a lot of weasel words and vagueness in that article. Is that a photograph at the top or an artist's conception? Have they actually built one? (What's an "internal field test", anyway? Is it like self-peer-review?)
If a thing like this worked reliably, you'd want dozens of them per village, each in the middle of a planting bed of food plants.
