Ask 'Rocket Guy' Brian Walker
We've mentioned amateur rocket enthusiast Brian Walker (better known as Rocket Guy) a few times before; he's one of those people who aren't content with building Estes model rockets that carry eggs or tiny cameras. Instead, Rocket Guy is building a backyard rocket -- and he hopes to launch himself about 35 miles into the air. His launch, originally planned to take place sometime this year, has been delayed for the best of reasons, but now's your chance to ask about the theory and practice of home-brewed rocket travel. We'll pass the best questions along to Rocket Guy, and post his answers soon.
Have you ran into any legal issues with your rocketry? Have the government had any significant impact (pro or con)?
I, like a lot of people, are quite skeptical about the success of your project. However, let us assume that you have launched yourself, everything went perfectly, and you are resting safely back on earth.
What do you think this will do to the future of space travel? Do you think this will set a precedent for the private industry to get involved in space travel?
This isn't a question, but a plea to the slashdot editors.
;-)
Please perform this interview before his planned flight.
Thank You,
-Pete

Which parts or subsystems did you make, or have made, yourself, that you wish could have been purchased off the shelf for a reasonable price?
Which parts or subsystems do you think are candidates for standardization in the coming personal rocket industry?
Seems like you've done lots of mockups and landscaping, but I havn't seen any work on the actual engine (other than a single picture of it).
Having seen all the trouble with catalyst packs and such that other projects have had, how come you havn't done any test firings yet?
Have you even tested your pneumatic launcher?
Say you are successful, and I hope you are. What's next? Do you try it again only higher? Also any plans of donating your rocket to the Smithsonian? This would definitely be considered Air & Space history and be worthy for all to view. Or on the other hand after are you looking for monetary gain? Something like pay 12 bucks to see Rocket guy's Rocket?

How much of your project requires technological innovation on your part, and how much is just a question of raising funding to duplicate exisiting technology that governments have already researched?

Have you discussed rocketry with John Carmack and his friends at Armadillo Aerospace? They plan to eventually fly a manned rocket as well.
"And like that
In case something goes wrong, are you planning to take with you a large ten-gallon cowboy hat to wave around on reentry?
What kind of testing have you done for your design(s)? Wind tunnel tests, computational fluid dynamics, flying scale models, etc? I've also noticed that your design has changed considerably since the first time you were featured on slashdot, and as an aerospace engineer myself it would be interesting to know what your design criteria were and how you arrived at them.

Amateur rockets don't get to space or orbit because they're generally limited to low specific impule solid fuels. Is there much of a gain in specific impulse to be obtained by further research into hybrid (ie, plastic/nitrous oxide) propellants? How about exotic chemicals (buckyballs, multi-atomic nitrogen, fluorine for example) - any route for amateur utilization of these?
