The Kickstarter itself says: "You're supporting an entirely new type of technology that has the potential to inspire new ideas and future innovative products." No, you are not. Exploiting the pressure difference like this for inflation is not new by a long shot. Just pop down to REI: http://www.rei.com/product/829645/exped-schnozzel-pumpbag Edit: read rest of replies below for clarification.

When a new technology is introduced, more than one person may implement said technology, and in different ways. Just because someone else has used physics before doesn't mean this is not new.

There's a problem I had solved. Ver' nice.

Downvoted for agreeing that this solves a problem? Not belly-aching, but that was honest input. I was happy to see someone build this; I've hated thermarest valves since I've known them.

Someone might have read your comment as "There's a problem I had already solved" rather than "There's a problem I had, solved."

These guys have taken the same physical phenomena used in the newish Dyson fans and hand dryers and found a radically different way to use it.

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 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.

It is more expensive but only because it has an R value of 8.0 (the Kickstarter one has an R value of 1.0, which means it's not going to give you any protection from the cold ground whatsoever - even a self-inflating pad gives you more protection than that). You'd be amazed how much difference higher R values make on the quality of rest you get while camping. Is it slower? Maybe, but I inflate mine in two or three in…

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…

Thanks. As much as I hate to be "that guy", I think it's also important that people don't invest in a product on kickstarter that isn't going to match expectations, or isn't the "brand new innovation" that they say it is.

Just for further info: I camp a fair bit in Ontario. In September when the days are still hitting the high 20's (80's in Fahrenheit), the ground can still be cold enough that I had to trade up from an R-value 3 sleeping pad to this product. It's much comfier, very light and compact, and inflates really quickly. If you want to get into camping, being comfy at night is so important, I urge you not to skimp on your sleeping pad.

I looks like a wool blanket could help (R value around 4) http://en.wikipedia.org/wiki/Wool_insulation

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 action. The OP's invention avoids this necessity, making it both new and improved.

I'm planning to buy a Dyson Air Multiplier heater/fan very soon so this comment intrigued me. I'll be sure to go to a store to check them out in advance. I didn't really like the video you linked as I find it to be a bit of a red flag when someone calls something "overpriced", especially when they go on to be very negative about it - it almost feels like jealousy. Still, I'll look into it before I buy. I don't suppos…

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.

Get a ceiling fan, they're usually a lot quieter.

I'm willing to bet they began the process of patenting the design prior to putting videos of it on the internet.

Even if they did, applying for a patent doesn't indicate that you have a valid patent, nor does it provide any protection whatsoever for patents that came before.

The implication was that as part of the patent application process, one would normally seek out prior art.

What's the name of the phenomena? ot: I find Dyson's bladeless fans way too weak (and loud) Edit: https://en.wikipedia.org/wiki/Venturi_effect

Not Venturi. Venturi is when an airflow in a constricted space is further constricted.
