Sounds like a dream come true, right? It's not, it's pure bull shit, it requires a Hell of a lot more energy to convert a liter of water than they attempt to claim.Checkout the site, watch the video. I can only imagine they're scamming govts or the UN.http://fontus.at/
i don't see anything about a guarantee under any and all conditions.
Probably a Peltier chip, with 2 heat sinks, one on each side. They use them in portable electric coolers.... something like <20% efficiency.I was making the SAME THING for keeping a safe dry. One side is cold, the other is hot. Pull the air over the cold side, the humidity condenses, then push the same cooled (and dryer) air over the hot side, and it reheats, drain the water away, just like a miniature dehumidifier.Whatever is in the air, pollen, pollution, essence of skunk, will be condensed ... to some degree, into that bottle.http://3.bp.blogspot.com/-Jmk4XgQF8XY/T8eC5S6LkpI/AAAAAAAAACI/kqjYxLNjLS4/s1600/peltier.jpgHere's how to set it up...http://www.skycraftsurplus.com/images/products/detail/sk4503.jpgIf you use those really nice copper heat-sinks off a CPU cooler, there's very little else one can do to increase efficiency.If there's $30 in parts, I'd be surprised.... the rest is marketing.BTW... the little junctions are FRAGILE, one breaks and the whole thing is done. Vibration is a "chip killer". Overvoltage/current kills them in seconds, and if you're dumb enough to be holding one between your fingers (yep, did that), one side will freeze to your skin in a split second, while the other burns your fingerprints into the ceramic. ... really sucks having a burnt thumb and a Peltier chip stuck to your index finger, 'cause you thought you were smarter than the "Warning!!!" on the packing label.Peltier chips are really neat things.... that nobody has figured out a really good use for. They are really energy wasters and have a miserable habit of failing at the most inconvenient times... or in the case of the chest coolers, draining your car battery completely flat, because you forget to unplug it before you crawled into the test... (did that too, several times)
Which is why I called BS on their claim of capturing water with a tiny solar panel, you could really call it that.Look at that thing, maye 6"x6" at best, and the sun creates 1000 watts of energy per sq meter that hits the earth during perfect conditions, the best solar panel captures roughly 10 to 20% of that, if memory serves me, which means their panel possibly captures less than a watt, nowhere enough to create heat to offset air temp and capture moisture.
It really misses out on the BEST part of the day to capture water, early mornings, before sunrise.10-14% solar panels were pretty much the norm, so the energy input is minuscule, so is the overall unit.As long as the cooling side can get below the dewpoint, and suck alot of air across the heat sink, it'll so something.
the guy who reviewed the thing, also well known for reviewing Oscilloscopes and electronic test gear.... er, ah... looking for a good descriptor, besides, he's a bit of a biased nerd, IMO.250watts per hr., doesn't take into account the days you encounter a downpour, or peddling so hard, your dripping sweat gets sucked into the bike mounted unit (that's pulling water in the form or rainfall or sweat - right out of the air!!!)At any rate, those little Peltier chips are a fun thing to play around with, they break and burn out easily, and if my source of water depended on anything using a Peltier chip, I'd have a back-up plan or a healthy reserve system.On the other hand, if my micro-hydro, wind generator, or solar panels needed a dump load.... sure, dehumidify a gun case, ehhhhh.... it's just a toy. More fun at a bar, "I bet you can't hold this between your fingers for 5 seconds!" No joke, I have a handful of 120watt, and a couple rated at 400watts... they are just toys. Oh, and when you take the power away, if there's a cold source on one side, and heat on the other (serious Delta-T), they will generate a minuscule amount of power, not like a battery's 80% efficiency, more like light a single LED... couple of watts.
