I like the concept. I'd be willing to contribute though if it deflated and folded up small instead. I don't mind inflating an air mattress.

I agree, but this is not new by a long shot and it's not even new in the domain where it is being applied. So I stand by my statement that the claim being made in the Kickstarter is untrue.
not new by a long shot Prove it. Paste a link to an inflatable with an integrated high-speed air filler that doesn't require anything but your mouth to operate. edit: I will add that this invention is clearly new compared to the pumpbag because it is a single device taking advantage of pressure gradient. The pumpbag only uses pressure gradient to fill the pump; force from your body after the fact provides the pumping…
Sure, but the reason that the Exped uses a bag which you pump is that you can increase the pressure in the mattress significantly.
So, OK, I'll agree with you that this is new because the pump is integrated. But I doubt it'll turn out to be superior.
And so I can't post a link to a similar product because the similar products don't do it that way for a reason.

Whereas your first comment came off as a bit pithy, this was a really informative one. Thank you for the lesson on r-value and its importance. Not an avid camper, but I sometimes do overnights in the cold and today I learned something important about air pad insulation. Thanks again. Per REI's page on the topic, here's what they have to say about R-value: "Insulation is measured according to its capacity to resist (t…
I looks like a wool blanket could help (R value around 4) http://en.wikipedia.org/wiki/Wool_insulation
The problem is that adds to your weight. Not important if you're car camping, but important for hiking.

#74The stuff about inflating with your mouth is a bit of a straw man. If you inflate say a Thermarest NeoAir or a Packraft you're more likely to use something like an Instaflator now: https://www.youtube.com/watch?v=yJLVYfg88TE (Thermarest have their own variant on the bag inflator for the neoair - but the principle's the same)
The backpacking mattresses are still inflated by mouth - I’m certainly not carrying another 2 oz on my back for a week just to save a minute on inflating. And neither are any of the folk I go into the backcountry with. But this mattress is not aimed at us either - it weighs in at 24 oz with an R value of 1! So perhaps the Thermarests owned by people who’d buy this are currently being inflated by Instaflators...
Do you have a good source for the state of the art in backpacking mattresses? I last bought one back in the 1990s, and I guess now I'm interested to see a comparison table of maybe weight, R-value, and price for reasonable choices.

Example of the the baader-meinhof phenomenon? I learnt about this it a few days ago, as its the same phenomena used by Brain Brushwood in this weeks scam school - http://www.youtube.com/watch?v=at0xRBacJF8 where he attributes it to the 'bernoulli effect'.
I don't think you mean Baader-meinhof ( http://en.wikipedia.org/wiki/Baader-Meinhof_(disambiguation) ) They do mention the bernoulli effect in the Kickstarter video
I think amvp saw it a few days ago and then again now, hence the reference to the Baader-Meinhof frequency illusion. I hadn't heard about that until 5 minutes ago but I grew up in Stuttgart so the real Baader Meinhof guys are some bad memories from my youth. No doubt I'll be seeing random references to Baader Meinhof in the next few days.

#76I'm afraid there's already a matress that does this. It's from exped, I own one and it's awesome, and better implemented than this because you're only inflating a small pump sack, and can use it to build pressure in the mattress. Here's a video: http://www.exped.com/exped/web/exped_homepage_na.nsf/b43popu...
I wish you had shared this sooner before I made my purchase :)
I noticed the R value of the kickstarter pad. But at 3+ inches it has to be above R:1. My guess is they haven't tested it so just to be safe they have put an R value of 1. Just look at other bags or pad at similar thickness and their R value should at least be in 3-4 range.

Speaking of which, I wonder if they'll need to deal with patents. From what I understand Dyson has that technology wrapped up tight. PS - Dyson's fans are also terrible. Great concept, poorly executed. They wanted them to be sleek, so they used tiny motors which are LOUD making Dyson's Air Multiplier far louder than other fans WITH blades. PPS - http://www.youtube.com/watch?v=fVbEE0Qe4BQ
I haven't (and will not) invest any time doing the numbers but, a quick think about the Dyson fans leads me to conclude the whole thing is a big marketing scam. Kudos for pulling it off, but the thing ain't magic. For starters, it has blades. It definitely has blades. They are simply concealed. It's like saying my computer has no fans when the fans are not visible from the outside. Nonsense. Second, it takes a certai…
I haven't seen any checks on this, but I suspect the Dyson can probably move more air than a regular fan. It probably isn't more raw energy-efficient, but it can be more comfort energy-efficient (more comfort for the same energy), because their principle makes sense -- if you use a regular fan, you air speed is going to be dictated by the blade speed, while the amount of air depends on the area. With the dyson, they can get a much greater area, which dictates confort, with the same air speed, because they've distributed the stream along this circle, and it picks up more air as it goes (and loses speed).
My point is, it may be poorly executed, but in principle it sounds nice, not even taking into account you don't actually have an exposed blade to worry about. It's not a scam.

He did mean Baader-Meinhof phenomenon (recency illusion). The Wikipedia editors deleted the old entry and made it a straight redirect to the "cognitive biases" page for some bizarre reason. I'd link to an explanation of what it is, but I'm sure you'll find a reference to it again in the next few days.
Re: New closure allows camping mattress to be inflated in seconds
#79It is interesting as what other application this would have? If I could replace my mouth (the source of the wind) with an electric fan, what else can I do with this?
Or with actual wind. Scale it up, use it for rapid construction of emergency housing? An inflatable former can be covered with concrete quickly and then deflated.
How large would it need to be scaled in order to generate useful amounts of power by sticking a wind turbine on it?

I've played with Dyson's Air Multipliers in a department store and they really are that loud when you turn them up to mid-high setting. "Too loud." I wish I could recommend you a high quality fan, I've looked, and frankly it is pretty slim pickings out there. Currently I have an unbranded Chinese-made one. I'd kill for an ultra-quiet nighttime one, and pay good $$$ for it too.
You don't have to kill for one. I've had a Lasko tower fan for about three years now. It's almost entirely silent, moves a lot of air, and comes with a remote. I did have to take it apart to regrease the bearings once, but other than that, it's been a great fan. Also comes with a remote. http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3D...
Do you have any advice on regreasing the bearings? I've got one of those fans but it's starting to cease up on me.
