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.

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.

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.

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.

Personally, I'm not terribly concerned about mattress air pressure once it reaches a certain point. I'm more concerned about the mattresses ability to maintain a certain level of air pressure. My use case would probably be camping/hiking and if the windcatcher can provide enough pressure for my body to stay suspended off of the ground, then I'm fine, personally. I do realize that's not necessarily everyone's criteria, though.

I'll also say that I really dig the way the schnozzle works and I'd probably prefer that, mostly because of the dual use as a stuff sack, and that it gives me more options when it comes to mattress selection.

I just like that there are people trying different ideas out, and I get to recline in my chair and see what sticks.

Besides being able to achieve higher pressure (which I agree isn't terribly important), the Expeds need extra force to inflate because they're filled with down or synthetic insulation, which dramatically increases their insulating value. A R value of 1.0 isn't useful as a sleeping pad for hiking except in really warm climates. 2.5 is a realistic minimum for a three-season pad.
