My bullshit detector went off a few times. Maybe it's just bad reporting, but it sounds really fishy. And leaves too much unanswered.
Let's absorb less energy to get higher efficency?
Drawing heart from the surrounding environment? Not unless you have somewhere cold to sink it. The black thing catching sun is not it.
How are they condensing this water vapor?

My bullshit detector went off a few times too. Most anything that claims "higher than theoretical efficiency" is by definition bogus; either the theory or the measurements are wrong. I really doubt the evaporative media makes much of a difference; I think the whole think is BS.
Also, as you say, they say nothing about where the water is condensed, or anything else about it.
