Re: SpaceX News

They didn’t even try to catch. No reason was given, but rough seas + night attempt may have been factors. Awesome time lapse: https://www.reddit.com/r/interestingasfuck/comments/9mcs4f/maybe_the_most_beautiful_shot_of_falcon_9_launch/ I have read they have already announced no fairing recovery atte...

Re: EMC2 news

The address of the whole ENN Group is accessible at http://www.enn.cn/wps/portal/enn.en , but I have not been able to locate the symposium site from there. Maybe the third option will work out and the missing site will again be accessible on the first of October? Apparently so; it's accessible now....

Fluidic? The article doesn't say it has liquid electrodes like a vanadium battery. Do you have a link?

Re: 2018 NIAC Symposium

It would be quite humorous if a man-made crystalline structure of paired lithium atoms turned out to be a key material for the Mach Effect device. :roll: What's worse is that over 60 years ago, Vernor von Braun wrote a book about the settlement of Mars. The title of the Chief Executive of the Marti...

Re: 2018 NIAC Symposium

I’m a software developer, not a scientist, but I think there’s a strong parallel with the “it works on my machine” phenomenon I’ve experience quite often. Frequently code written on my machine that works great for me ends up not working for a tester (or worse, a customer) because I didn’t account f...

Re: 2018 NIAC Symposium

Heidi Fearn will be taking a working device to Dresden and will stay with them until they get it working. Dresden had problems with a previous device and published bad results. Hmmm. Does this interfere with the concept of independent validation? I think not after Tajmar cooked the last piece of ha...

Re: 2018 NIAC Symposium

And Dr. James Woodward presented on the Mach Effect Thruster, which has recently been reported by Dr. Heidi Fearn to have an efficiency of 60mN/kW, placing it on a par with Hall Effect Trhusters.

Re: SpaceX News

Pathological skepticism is great! I think everyone could use more skepticism. I am comforted that you all are not concerned by this design change, though no one has really addressed how such a large surface area can be reliably/safely actuated at hypersonic speeds. As an aside, why would separate l...

Re: SpaceX News

Also the fins have the depth to house a truss carrying the load of the now vertically deployed legs to the fuselage, although carbon fiber has such a high stiffness it may be incorporated into the skin of the fins instead of being a frank truss structure. Can you imagine the complication of hanging ...

Re: SpaceX News

Who is inventing details? Do you have a good reason to know Musk is wrong when he states the new design is riskier? Aside from that, I'm trying to work out your ground rules here... quotes irrelevant to my point are preferable to ones that spell out my concern almost verbatim? Is there some further...

Re: SpaceX News

“Prior to this the idea was to decouple the legs from the wings. This wasn’t very aesthetic, so now we have 3 large legs/wings that actuate. It is slightly more risky because we are combining multiple functions together” Don't care what you choose to fixate on, or details you care to invent for you...

Re: SpaceX News

Disappointed by updated design. Turns out the only significant difference (added fins) were not a result of engineering, but simply that Musk liked the aesthetics more. He even admitted the design was now riskier as a result. This guy legit scares me now. It legit scares me you spread FUD so easily...

Re: EM Drive

Hopefully this will result in more energy going to Woodward's MET concept. Not according to your posted link: As for the mach effect thruster, it is also not doing well. Several high level physics heavy presentations, including one by Dr. Rodal, that make the claim that the mach effect thruster can...
