#2Kickstarter plz.

#3Cyclists drink half a liter per hour in cool conditions. In the hot, humid conditions necessary for this to produce its maximum of half a liter per hour, they should drink at a much higher rate.

#4I wonder what the power requirements are,
The cooling system has to be cooling the air that passes through it down to the dew point, if the ambient temperature and the dew point are too far apart, it's going to consume too much power to be practical.

#5Fantastic! One step closer to making Fremen and Dune technologies reality!

I can see this being pretty useful for long touring rides, where you're riding for a long time but not necessarily pushing very hard.

"After more than 30 experiments, I finally achieved a constant drop-flow of one drop of condensed water per minute"
Guessing the diameter of a drop at 1mm, and assuming it to be cubic, that is 60 cubic mm per hour. Rounding up, we get 1 cc per hour. A U.S. teaspoon is just under 5 cc. Alternatively, get a small cup of water every 24 hours.
There can be about 30 cc of water in a cubic meter of air, so you would have to pump 16 cubic meter of air through this thing and extract all the water to get at 500cc per hour. With a 10 by 10 cm opening, that is a 1600m long column. A bicycle can easily do ten times that speed, so that sounds doable, but that is at maximum efficiency and the article doesn't say he has done that, so I fear that 500cc is wishful thinking.

#8For some reason I wouldn't want to drink the water after biking through a swampy area.

#9Half a liter in a few hours is way less than a cyclist needs. This is renewable and a bottle isn't but I can pack much more water in the volume of the device and get other water when I stop. If I can't find water maybe I'm in bigger troubles than half a liter can save me from (in a desert, really?). It's not worth it.
However, put a bigger device on a car or on a boat and that can be useful.

until you realize that the drag created by the larger device actually costs more in energy to create the water than other sources.
im curious if this device on your bike would cause you to burn more water than what it produces
