1st Transcontinental & 1st Trans-Atlantic Balloon Overflight- California Near Space

I’m not up on my balloon news! posted here for the purpose of completeness.  California Near Space  was already slashdotted four days ago.

Amazing, they beat the White Star team and Robert Rochte, who threwdown on transatlantic ballooning earlier in the year with his SDG-10, which appears to still be grounded.

White Star’s not working with off the shelf balloons though– they’ve got a bigger goal: DIY  tropospheric superpressure balloons.  these will be capable of multi-week flights, if successfully built.  Dan Bowen’s talk– Jump to 3:30 into this talk, and see the superpressure tetroon discussion.  5:40, discussion of Rochte’s designs.

These are the best basic balloon kit instructions, beautiful.  Check out the awesome maps he got with Bonny and other grassroots mapping folks.

Grassroots Mapping PDX: Taping up balloons

I’ve finally collected and edited the workshop’s videos and instructions:

Taping Instructions

Follow the first two pages of my Balloon Building Guide to make a tetrahedron balloon.  Tape carefully.

My balloon guide’s rigging is for short flights in confined urban areas.  We’re going to use a different rigging for aerial photography.

One corner of the balloon is used for filling, and is tied off, like a trash bag.  A second corner is re-enforced, and a loop of tape attached.  To the tape is tied a short length of line.  The knot used is a Bowline.

attach a swivel to the balloon so that any spinning won’t twist the line or the camera.

Boy Floated Away- NOT EVEN POSSIBLE

Helium can lift approximately 65lb. per 1000 cubic ft. from the images in the video, the balloon was no more than 12ft in diameter, or approximately 900 cubic feet. The boy, the balloon, and all the equipment can’t weigh less than 65lbs. Next time you want to wast millions of public money, do the math first.
