Re: re: Space Lift Tests Progressing
Why in the ocean? Wouldn't the top of a mountain in Africa or South America be better? 6200 MPH!! OK doesn't ribbon usually twist? This may make problems with providing power to the robots (if they use photo cells for power) and could limit their speed. It has to be on the equator since the top of ...

re: Level 1 cert. attempt
there are no such things as low power certs- you can operate anything up to a "G" size engine without any cert at all.

re: SO SMALL
I am mostly suprised that it will run over 500 hz on propane. To the best of my knowledge this has never been done before. My best attempt was 687 hz on acetlyene.
