Where is he getting money for this scam?

Are there people insane enough to fund him or has he become millionaire by some other business?

Itís not a scam. Itís a wild idea that may not work, but heís been working on it for decades, slowly developing bits of technology. They have a small budget and lots of volunteers. Some donations and also paid work lifting objects up to 100+k feet. Such as the Toshiba commercial over a decade ago:

The flight of Away 131 was a success. The vehicle has been recovered and recovery team is back home. More after we kick the dust off.

"may" is an understatement.

It will not work because of physics.

And no amount of "technology" will change physics.

It's fundamentally the same concept as hypersonic spaceplane-to-orbit: utilise a high enough TWR and you can generate lift from as rarefied gas as you want by tuning drag and thrust to continue accelerating without falling. SCRAMjet waveriders aim for a high TWR by maximising the 'T'. JP Aerospace aim to minimise the 'W'. That they use an 'airship' is secondary to them creating a structure with a large lifting area with minimal mass (a pressure-stabilised hypersonic aircraft), it being LTA for the initial portion of flight mostly just helps with logistics of getting it to a starting altitude.

There's nothing physically preventing the concept from working. Whether it works economically, or whether the engineering challenges are tractable (for SCRAMjet SSTO they have repeatedly not been) is another matter.

Using "physics" as a reason without even listing what principles are being violated is disingenuous at best. As far as I know none of the laws of thermodynamics are being broken, nor is this a reactionless drive or is it breaking the speed of light.

It is, however, balloons in spaaaace, and that may well turn out to be impractical. But impracticality *is* something that technology sometimes changes.

Or not. But as of right now it should be noted that they have flown higher than, say, ARCAspace...

Edit: Steven Pietrobon has corrected me that ARCAspace has indeed lofted a suborbital rocket (from a balloon in fact!) higher than JP Aerospace has managed to fly. So, point for ARCA...

Yeah, itís a weird project and Iím not sure the engineering equations close to a real system, but itís certainly not nonsense!  I love seeing what theyíre up to and I hope they can perhaps learn useful things.

It's not a scam. It's a service.

He promised to bring us our names to near-space, and he delivered.

I'm quite happy with the outcome of the latest mission. Remember - I've supported other initiatives on Kickstarter that promised to bring names and message to near-space and space, and they never delivered.

Here's a photo of our names (myself included) photographed on August 14, during this mission. Thanks, John Powell!

This sort of garage level MHD work is interesting, potentially from a practicality perspective.

ARCA flew their balloon launched Helen 2 suborbital rocket to 40 km on 4 October 2010.

http://www.parabolicarc.com/2010/10/04/romania-enters-space-age-arca-launches-rocket/

Not sure what the record is for JP Aerospace, but they reached 29 km on one balloon flight.

Thanks for the correction! Boy, that was eons ago with a totally different rocket design, but you are correct, ARCAspace as a company has lofted something higher than JP. It does remain to be seen if their current steamkettle can get above balloon height, though.

Interesting to note that ARCA's balloon launch was also a sea launch.

Pneumatic valve open and close near peak altitude aboard Away 131. This is just a draft version of the valve. After a few more high altitude tests it will be ready to go on the airship.

We have made a breakthrough in our #Magnetohydrodynamic (MHD) plasma engine program. We are using ablative graphene electrodes in the #MHD unit to eliminate electrode fouling. This is part of our program to develop hybrid electric/chemical rocket engines for the Airship to Orbit program.
