We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
but for a human, walking up to an already-drawn circle, you can either a) measure the diameter (100% effective and accurate)
Sorry, if you "walk up on a circle" you can't guess at a diameter either. You have to make a geometric construct to find the center so your diameter measurement is correct. You might as well measure the radius at that point.

It looks more like the rail truck accelerates the launch vehicle to mach 1 which leaves the end of the track and the scramjet lights and carries it and its payload to mach 10 at about 20 miles altitude. The payload then separates from the launcher, the rocket ignites and sends the payload into orbit. The launch vehicle returns and lands for reuse.
This sounds a lot more feasible than a mach 10 rail gun!

Usually, the best thing for fire fighters to do with compressed gas fires is to let them burn. The fuel most likely can not be removed because the container is broken or valves blown off, etc. Controlling the area and letting the fuel consume itself is often the best or only choice.
All very true. Thank you.
It got me thinking though. I've never seen a solar collector as efficient as a field of sugar beets.
