The Kline Directive: Introduction

Posted by in categories: business, complex systems, defense, economics, engineering, ethics, finance, philosophy, physics, policy, space

Science and engineering are hard to do. If it wasn’t we would have a space bridge from here to the Moon by now. If you don’t have the real world practical experience doing either science or engineering you won’t understand this, or the effort and resources companies like Boeing, Lockheed, SpaceX, Orbital Sciences Corp, Scaled Composites, Virgin Galactic, and the Ad Astra Rocket Company have put into their innovations and products to get to where they are, today.

If we are to achieve interstellar travel, we have to be bold.
We have to explore what others have not.
We have to seek what others will not.
We have to change what others dare not.

The dictionary definition of a directive is, an instruction or order, tending to direct or directing, and indicating direction.

Dictionary of Military and Associated Terms, US Department of Defense 2005, provides three similar meanings,

Debunking Pulse Detonation Engines — Yes, No, Maybe

Posted by in categories: business, defense, engineering, military, nuclear weapons, physics, space, treaties

Previous posting in this Debunking Series.

In this post we will look at the last three types of engines. Can these engine technologies be debunked?

Start with the boring stuff. Nuclear/plasma engines. For more information look up Franklin Chang-Diaz’s Variable Specific Impulse Magnetoplasma Rocket (VASIMR). Real. Cannot be debunked.

Now for the more interesting stuff. The second is Pulse Detonation Engines (PDE). This type of engine uses detonation waves to combust fuel and oxidizer mixture. “The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave initiated by an ignition source.” Theoretically this type of engine is capable of speeds from subsonic to Mach 5.

Debunking the Black Hole Interstellar Drive

Posted by in categories: business, engineering, fun, physics, policy, space

Louis Crane and Shawn Westmoreland co-authored the paper Are Black Hole Starships Possible? (http://arxiv.org/abs/0908.1803) that suggested that one could use Small Black Holes to propel starships close to the velocity of light for interstellar travel. To give them credit, they stated that this is at the “edge of possibility” and would only be possible in the very distant future:

“The purpose of this paper is to investigate whether it is possible to build artificial BHs of the appropriate size, and to employ them in powerplants and starships. The conclusion we reach is that it is just on the edge of possibility to do so, but that quantum gravity effects, as yet unknown, could change the picture either way… Many questions which arise in this program lead to calculations in general relativity which have not been done. Whatever the other merits of our proposal, we are confident it will pose many interesting problems for classical and quantum relativity.”

Note, BH = Black Holes

That is it. Crane & Westmoreland were presenting an academic exercise to pose “many interesting problems for classical and quantum relativity”.

iPhone 5 Hyper-Anticipation: It Didn’t Mean What You Think it Meant (AGAIN)
https://lifeboat.com/blog/2012/09/iphone-5-hyper-anticipatio…eant-again

Okay, now — bear with me on this — and check it out:
For now and for better or worse, The United States is home to a plurality of the world’s techiest technology, investment capital, productive creativity, and cutting edge research. As such, hiccups in those technology-driven economies of real currency and ideas can ripple around the entire planet.

Amid considerable anti-intellectualism and various public & private R&D funding issues, American tech leadership and innovation is stuttering and sputtering and might be in danger of faltering. While we’re not at that point just yet, there is an interesting harbinger with a peculiar manifestation: New iPhone Anticipation Loopiness. As I said, bear with me.


_______________

This is a repost & redux from an October 5, 2011 Anthrobotic.com piece — published a day before the suspected-to-be-iPhone 5 was released as the iPhone 4S. While the fanboy drool and mainstream gee-whiz was considerably dialed down this time around (in part due to lots of leaking), the sentiment of this piece remains relevant and largely unchanged. Now, we did have the Nuclear-Powered Science Robot Dune Buggy with Lasers (AKA the rover Curiosity) this year, and that was very big, but on a societal level we still have a sad hole in our technology heart.

International Nuclear Services Putting Business Before Safety

Posted by in categories: business, economics, ethics, nuclear energy

Whilst I was checking up on C.O.R.E. (Cumbrians Opposed to a Radioactive Environment) this weekend, I read of latest plans to ship plutonium MOX fuel assemblies from Sellafield to the small German port of Nordenham near Bremerhaven on the NDA’s (Nuclear Decommissioning Authority) ageing ship Atlantic Osprey.

The Atlantic Osprey, built in 1986, is a roll-on roll-off ferry purchased third hand by British Nuclear Fuels plc (BNFL) in 2001 and converted to carry radioactive materials. It is the only ship not to be custom-built of the UK’s designated nuclear cargo ships, and so is not double-hulled, and has only a single engine, among other short-comings.

According to CORE it has a chequered history as a nuclear carrier that includes an engine-room fire and breakdowns at sea, and equivalent sister ships have historically been retired at or before a standard 25 years of service. Whilst the ship is soon to finally brought to the scrapyard, it is due to be replaced by a 25-year old ship Oceanic Pintail recently saved from the scrap yard itself — and one would get the impression that the Nuclear Decommissioning Authority are cutting corners on safety to save on expenditure.

CORE spokesman Martin Forwood has pointed out that INS (International Nuclear Services — a subsidiary of the NDA) appears hell-bent on shipping this MOX fuel to Germany on a third-hand ship with second class safety and kept afloat on first class INS PR alone” and on learning about the current state of affairs, one would be inclined to agree.

Flexible Path Flim Flam revised

I do not regret voting for this President and I would and will do it again. However.……I am not happy about our space program. Not at all. One would think there would be more resistance concerning the privatization of space and the inferior launch vehicles being tested or proposed. Indeed there would be objections except for a great deception being perpetrated on a nation ignorant of the basic facts about space flight. The private space gang has dominated public discourse with very little answering criticism of their promises and plans.
This writer is very critical of the flexible path.

It is a path to nowhere.

Compared to the accomplishments of NASA’s glory days, there is little to recommend the players in the commercial crew game. The most fabulous is Space X, fielding a cheap rocket promising cheap lift. There is so little transparency concerning the true cost of their launches that one space-faring nation has called the bluff and stated SpaceX launch prices are impossible. The Falcon 9, contrary to stellar advertising, is a poor design in so many ways it is difficult to know where to begin the list. The engines are too small and too many, the kerosene propellant is inferior to hydrogen in the upper stage, and promising to reuse spent hardware verges on the ridiculous. Whenever the truth about the flexible path is revealed, the sycophants begin to wail and gnash their teeth.

The latest craze is the Falcon “heavy.” The space shuttle hardware lifted far more, though most of the lift was wasted on the orbiter. With 27 engines the faux heavy is a throwback to half a century ago when clusters of small engines were required due to nothing larger being available. The true heavy rocket of the last century had five engines and the number of Falcon engines it would take to match the Saturn V proves just how far the mighty have fallen.

GENCODE Apocalypse

It is a race against time- will this knowledge save us or destroy us? Genetic modification may eventually reverse aging and bring about a new age but it is more likely the end of the world is coming.

The Fermi Paradox informs us that intelligent life may not be intelligent enough to keep from destroying itself. Nothing will destroy us faster or more certainly than an engineered pathogen (except possibly an asteroid or comet impact). The only answer to this threat is an off world survival colony. Ceres would be perfect.

Questioning the Foundations of Physics to Achieve Interstellar Travel: Part 3

Posted by in categories: business, defense, engineering, physics, space

Part 2 Here

Need For New Experiments To Test Quantum Mechanics & Relativity
We now have a new physics, without adding additional dimensions, that challenge the foundations of contemporary theories. Note very carefully, this is not about the ability of quantum mechanics or relativity to provide exact answers. That they do extremely well. With Ni fields, can we test for which is better or best?

A better nomenclature is a ‘single-structure test’, a test to validate the structure proposed by a hypothesis or theory. For example, Mercury’s precession is an excellent single-structure test for relativity, but it does not say how this compares to say, quantum gravity. On the other hand, a ‘dual-structure’ test would compare any two different competing theories. The recent three photon observation would be an example of a dual-structure test. Relativity requires that spacetime is smooth and continuous but quantum gravity requires spacetime to be “comprised of discrete, invisibly small building blocks”. This three photon observation showed that spacetime was smooth and continuous down to distances smaller than predicted by quantum gravity. Therefore, suggesting that both quantum foam and quantum gravity maybe in part or whole invalidated, while upholding relativity.

Therefore, the new tests would authenticate or invalidate Ni fields as opposed to quantum mechanics or relativity. That is, it is about testing for structure or principles not for exactness. Of course both competing theories must first pass the single-structure test for exactness, before they can be considered for a dual-structure test.

Questioning the Foundations of Physics to Achieve Interstellar Travel: Part 2

Posted by in categories: business, defense, engineering, physics, space

Part 1 of this Essay is here

The Missing Link, The Ω Function
General Relativity is based on separation vectors. Splitting this separation vector into two equations, gives one part a function of mass and the other a vector-tensor function. This gives rise to the question, can the mass part be replaced by something else say an Ω function, where Ω is as yet undefined but not a function of mass? Maybe the Ω function should be a description of quark interaction, and not mass?

Now it becomes obvious that the theoretical physics community has focused on the vector-tensor part to the complete omission of the Ω function. That is, there is definitely the opportunity to question the foundations of physics.

Looking at the massless equation for gravitational acceleration g = τc2, change in time dilation divided by the change in distance is what describes a gravitational field. A small body orbiting the Earth has a certain velocity which can be converted to time dilation. Change the orbital radius of the small body by a small amount, less or more, gives a new orbital velocity and a new time dilation. Therefore, divide this change in time dilation by the change in height and multiply by the velocity of light squared, gives the gravitational acceleration present. The same is with a centripetal motion. Use the velocity along the radius at any two points. Determine the change in time dilation then divide this change in time dilation by the change in radius, the distance between the two points. Then multiply by the velocity of light squared, gives the acceleration present.

Lunar Space Station vs. Asteroid Mission

The glacial pace of NASA’s human spaceflight program –even with the glaciers melting- may possibly see human beings leave Earth’s gravitational field in 2025. Possibly.

The missing piece of the puzzle is a radiation sanctuary massive enough to protect a crew from a major solar event on such a journey.
