Re: New John Goodenough battery with high (too high?) energy density

Why? A simple probability calculation: How many battery breakthroughs a week do we have? How many find their way into a working commercially available unit? Your maths are a bit off there. The numerator should be “How many battery breakthroughs a week by the original inventor of the Li-ion battery ”.

How to catch a fairing... try, try, again...
If it is ejected at about the same time as the first stage, and has a parachute, why not a ramchute and fly it back to the launch site?

Re: The list of duds

If you want a high capacity “flywheel”, look up info on the “launch loop” Properly suspended you can get ~8km/sec of velocity for your kinetics equation.

Re: EMC2 news

What about handing the hardware over to other scientists to allow them to confirm the findings and/or explore the concept further with additional experiments that might not have been contemplated during their original testing of the concept? I'm sure there are other people who would love a chance t...

Re: Comets can’t explain weird ‘alien megastructure’ star after all

How is this for speculation. There is a smallblack hole or neutron star orbiting the visible star and it keeps the orbital debris from coalescing. Then, on occasion, it gravity lenses the star light toward earth.

Hmmm. “Classified mission” that “failed”? Perhaps they just want folks to THINK it failed. ;)

Re: NTR fuel

Meta-stable hydrogen would ake a good fuel precisely because the energy needed to break the H2 bond is stored in the fuel. That is quite a bit of additional energy.

Re: Goodbye Tension, Hello Pension

When I was retiring, I was setting up to become a contractor. I said, "I'll take month off then start briging in the BIG bucks". Well, that month stretched just a bit. It has been ~5.5 years and I find I LIKE being retired. :D
