Available he http://www.amazon.com/Airship-Aerody..._bxgy_b_text_b The website of the Experimental Lighter than Air organization: http://www.xlta.org/ There are a couple of PDF docs worth downloading in the LIBRARY page and further links to other sites in the LINKS page (naturally). Hope some of this helps. |

It seems folks expect little old me to accomplish 100+% of everything. I didn't realize that I was being thought of as far better than Einstein that had teams of assistants (aka minions and peers) working as an intellectual cartel on his behalf. By way of expressing rigid composite should suggest this is not an inflated balloon application, as proposed by Yavrouian, not that efficiently ballooning science instruments below them thick clouds isn't technically doable as relatively cheap, especially on behalf of the micro electronic packages that involve so little mass and require such little energy as they outperform their task in most every aspect. Starting from scratch, this custom rigid composite airship is capable of good size and substantial payload, and its going to be like nothing ever before utilized on Earth or any other planet. Perhaps the closest analogy of anything terrestrial is going to be a nuclear submarine, whereas instead having its Venus buoyancy created by either a vacuum that’s easily managed by way of getting CO2 pumped out, or merely displaced from the top down with the failsafe gas of hydrogen. I was thinking along the lines of using rigid/hard composite spheres, arranged into an airship format (5 in tandem) that’s kind of aerodynamically suited to the task at hand. This application requires more than a simple balloon, especially if active flight and navigation is incorporated. . – Brad Guth |

Interesting, as to how the entire DARPA Usenet/newsgroup thing grinds
itself to a bloody halt whenever something really interesting comes along. It's as though the Planet Venus is just as DARPA taboo/nondisclosure rated as is our physically dark moon, so much so that not even the regular laws of physics nor the best available science can be discussed without my having to receive more than my fair share of mainstream status quo flak. If you'd care to learn more (1-253-8576061), or just to share and share alike would be kinda nice.
