some fun math depending on their claim that they can condense 1L water in 150min if humidity is 99% at 46 deg C (picture).
Latent heat of evaporation of water: 2270 kJ/kg
=908 kJ/h = 252.2W + the fan in the Airo model + heat exchange pump
this needs about 2 sq meter solar panel
all at 100% efficiency
I think I'm temped to pick up the whiteboard marker...
Fine print on the project page:
It is explicitly pointed out that the products which serve as Perks are in the development phase. It cannot be excluded that during the development phase technical, economical or other circumstances arise which may result in (i) a delay of the delivery of the Perk or (ii) the production and delivery of the Perk in a different form as regards functionality and/or design or (iii) even non-production of the Perk. In the latter case there will be no Perk delivered to the Contributor. Contributions will not be refunded. By making a Contribution the Contributors explicitly acknowledge the risks associated with the occurrence of one of the aforementioned events.
Pure evil genius!

What I got out of that video is a new Kickstarter/IndieGogo idea... It would take less energy to purify 1 L of your URINE than to condense 1 L of water out of air.
How about it everyone? Let's put together a URINE PURIFICATION DEVICE powered by solar so we can have an endless supply of water.
I conducted a series of experiments trying to identify the ideal conditions, materials and cooling systems. I simulated different climatic conditions in my bathroom, modifying the air temperature and humidity. After more than 30 experiments, I finally achieved a constant drop-flow of one drop of condensed water per minute. After developing a functioning inner system, I designed a compact and practical hull which can be easily attached to a bicycle, integrates the water bottle and can be comfortably handled.
I doubt that this is just a scam. I rather think that the guys are very stupid and belive this can be done (at least the design guy).

Well, that's what you often get with these industrial design and marketing/business guys. They just want to be "creative" and visionary, the unsexy part of making it actually work is the job of the engies in the dungeon. So when something doesn't work, it is the always fault of the engies for not trying hard enough and being negative and unconstructive with all their remarks how it can't work! If they only worked harder and were bringing solutions and not problems!
uBeam is/was a stellar example of that approach.
As far as I know, understanding thermodynamics or physics in general is not a requirement for a degree in design. Neither is math ...
I think he is a dreamer, otherwise he would not send his private contact information

I think that the guy is an industrial designer freshly out of school who has just dreamed up something, made a Powerpoint deck with a sales pitch and got an award from a business association for it, collecting a few design awards in the process (aka awards that judge the looks and presentation of the thing, not actual feasibility). And he then uses those as some sort of validation of his idea.
He has obviously absolutely no idea how to make it work or whether or not it is even feasible. I think they are hoping on getting a patent and then will shop around for a fool of a VC to license it to.
I just noticed the last paragaph regarding his testing process on the James Dyson Award page

So he tested it, and after "more than 30" attempts, managed to get one drop per minute in a rather unrealistic setup.
150 drops (over 150 minutes) is about 8ml (@ 50ul per drop). That's rather a long way off 1 litre!
