Cyclists 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.

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.

In the conditions where it produces half a liter of water per hour, you're going to need more than that just standing still.

Thats genuinely impressive. I'd be concerned about the lack of electrolytes though? Presumably cyclists would need to top those up too.

If you're concerned about electrolytes, I just invented a much better solution - just wringe your t-shirt after a ride and pour the water into a bottle, you'll have all the ions back

Earlier quoted context omitted.

"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 t…

Why did you estimate the size of a drop as being so small?

Not thinking enough and not googlinh it, I guess.

Straight from the article: "Under the right climatic conditions, Fontus can easily produce half a liter of water in an hour's time." We already know that it can produce half a liter per hour, but those same climatic conditions are when a cyclist needs significantly more than half a liter per hour.

I read that differently. On the one hand, there is the experimentally confirmed drop a minute. On the other hand, they do not state that that half liter has been confirmed experimentally.

I still doubt that number. Looking at http://atmosphericwatersolutions.com/wp-content/uploads/2012..., I see a machine that weighs 38 kg, consumes 373W of power, and produces 'up to 17 liters of water a day'. This thing would be an order of magnitude smaller, and produce almost the same quantity of water. Possible? Maybe. Likely? No. Because of that, I would like to see experimental confirmation of that half a liter per hour before accepting it as a given.

Also, see http://en.m.wikipedia.org/wiki/Atmospheric_water_generator which claims the U.S. army and FEMA use a system that needs a gallon of fuel for 'up to' five gallons of water. If something like this were known to be more efficient, I think it is likely they would use it.

The aquaboy data sheet only goes up to 25°. At 30°, it would produce more than a liter per hour.
