Re: Mach Effect progress

That seems to me a long winded reply. The thrust efficiency of any thruster is a figure of merit that exists for all thrusters. For a chemical thruster, it is the thrust over the energy from the reaction products burned over time. It is for stationary thrust only. Taking this figure of merit and pr...

No, he's not. Look at his latest post, for example, where he ignores the obvious interpretation of slightly clunky grammar in favour of a rather pointless attempt to accuse GIThruster of a logical fallacy. He is not innocent in this. What interpretation can be put on GIT last post, then? Either it ...

But watch the the Tyson interview to get the entire story. http://www.youtube.com/watch?v=HooeZrC76s0 I agree 100% with basically everything Tyson said in that video. Unfortunately your quote cuts out the very important first half of his sentence: " If that's how you want to invoke your evidence fo...

it is possible to say god is shrinking because scientific knowledge is growing. Not without implicitly endorsing a fundamental misunderstanding of the philosophical role of God. It seems ( cf. Kurt Gödel) to be a mathematical fact that science can never be 'complete' in the sense of a fully self-ex...

Chris, those aren't ad hominem. They're insults accompanying the argument, rather than being used as part of the argument.

Neither Woodward nor March would agree that others can only make unsuccessful attempts at repeating their work unless they were contacted. Did you even read GIThruster's response? What basically happened is that the guy doing the replication attempt threw together an experiment that couldn't have w...

You know perfectly well that there were numerous attempts at building a flying machine before the Wright brothers came up with the key to actually making one work. All of them failed for reasons that had not been obvious to the experimenters. Mach effect is not known to be real. But if it is, it has...

This is a completely hypothetical example, which you seem to be unable to resist trying to twist to fit your own slant. The point is that (assuming Woodward is correct) it is not straightforward to generate a measurable Mach effect in the lab, and someone who fails to educate himself on the pitfalls...

Is anyone doing a DIY replication? there was a replication attempt about 10 years ago, but that person did not contact Jim for guidance If one has not been blessed by being invested with the gifts of knowledge of the high priests of ME, then it would seem that one stands little chance to be able to...

1.7*60% =1.02g. Not how that works. Volume scales inversely with mean density. 5/0.6 = 8.333 Then redo the calculation: 5/cbrt(8.333)^2 = 1.216 You've still got 20% extra surface gravity. ... Another issue is that things happen faster at higher gee. Human reflexes are generally fast enough to deal ...

...the ability to generate large thrusts..you need to be ..running on resonance ... If you put a tuned circuit (the piezo and the ceramics) in the feedback loop of an amplifier you get an oscillation at the resonant frequency. (GIT = EE fail ) You need electrical and mechanical resonance simultaneo...

Is the 'scalar gravity potential' not 'g' here on earth? No, that's the gradient of the gravitational potential, and it's a vector. Not quite the same thing... So, next, one needs to look at whether 'mass fluctuations' can occur. The very essential notion of this, irrespective of any mathematical a...

@happyjack27: When I said "entropy", I meant what the poster I was responding to seemed to mean by it - the principle of nondecrease of entropy, which I also referred to as the "entropy condition". Known in continuum mechanics as the Clausius-Duhem inequality, as I recall. It's not so much a fundame...

State which line the error of premise occurs: 1) A 1 kg test thruster is subjected to a 130 uN of thrust generated by a 'Mach thruster' driven by a nuclear thermal battery that has an output electronically governed to 1 W. 2) It accelerates for 10 years (call it 300 Ms) from a given rest frame at w...
