The Kline Directive: Economic Viability

Posted by in categories: business, complex systems, defense, economics, education, engineering, finance, military, nuclear weapons, philosophy, physics, policy, scientific freedom, space, sustainability

To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, to change what others dare not. To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts:

1. Legal Standing. 2. Safety Awareness. 3. Economic Viability. 4. Theoretical-Empirical Relationship. 5. Technological Feasibility.

In this post I will explore Economic Viability. I have proposed the Interstellar Challenge Matrix (ICM) to guide us through the issues so that we can arrive at interstellar travel sooner, rather than later. Let us review the costs estimates of the various star drives just to reach the velocity of 0.1c, as detailed in previous blog posts:

Interstellar Challenge Matrix (Partial Matrix)

Propulsion Mechanism Legal? Costs Estimates
Conventional Fuel Rockets: Yes Greater than US$1.19E+14
Antimatter Propulsion: Do Not Know. Between US$1.25E+20 and US$6.25E+21
Atomic Bomb Pulse Detonation: Illegal. This technology was illegal as of 1963 per Partial Test Ban Treaty Between $2.6E12 and $25.6E12 . These are Project Orion original costs converted back to 2012 dollar. Requires anywhere between 300,000 and 30,000,000 bombs!!
Time Travel: Do Not Know. Requires Exotic Matter, therefore greater than antimatter propulsion costs of US$1.25E+20
Quantum Foam Based Propulsion: Do Not Know. Requires Exotic Matter, therefore greater than antimatter propulsion costs of US$1.25E+20
Small Black Hole Propulsion: Most Probably Illegal in the Future Using CERN to estimate. At least US$9E+9 per annual budget. CERN was founded 58 years ago in 1954. Therefore a guestimate of the total expenditure required to reach its current technological standing is US$1.4E11.

Note Atomic Bomb numbers were updated on 10/18/2012 after Robert Steinhaus commented that costs estimates “are excessively high and unrealistic”. I researched the topic and found Project Orion details the costs, of $2.6E12 to $25.6E12, which are worse than my estimates.

Debunking Antimatter Rockets for Interstellar Travel

Posted by in categories: education, engineering, physics, policy, space

Previous Post in this Debunking Series.

Why is it necessary to debunk bad or unrealistic technologies? If don’t we live in a dream world idealized by theoretical engineering that has no hope of ever becoming financially feasible. What a waste of money, human resources and talent. I’d rather we know now upfront and channel our energies to finding feasible engineering and financial solutions. Wouldn’t you?

We did the math required to figure out the cost of antimatter fuel one would require just to reach 0.1c and then cost at that velocity, never mind about reaching Alpha Centauri.

Debunking Conventional Rocket Interstellar Travel Once And For All

We did the math required to figure out how much fuel one would require just to reach 0.1c and then cost at that velocity until you reach Alpha Centauri and reverse thrust to orbit the star.

Debunking Time Travel (Looper)

Posted by in categories: media & arts, physics, policy, space

Previous Post in this Debunking Series.

I just watched Looper the movie. It is such a good movie and a great story. But then I’m biased. Anything with Bruce Willis is a great movie. Bruce Willis is getting older, which reminds me so am I!

For those who have not watched Looper I won’t give the story away … Looper is a must watch for science fiction fans. And there were other great movies and episodes about time travel. The three Back to the Future, and the Star Trek episodes, for starters.

That was the good news, and now for the bad news. Time travel is impossible. The mathematics behind time travel is excellent, but the physics is not. In contemporary physics, the mechanism of time travel requires wormholes. You get into a wormhole on one side and you pop out the other side either in the future or in the past, depending on what the wormhole was designed to do.

Physics of the Zero Point Field and its Applications to Advanced Technology

Posted by in categories: physics, space

I am very pleased to have received an email from Dr. Takaaki Musha of the Technical Research and Development Institute, Advanced Science-Technology Research Organization, Yokohama, Japan.

Dr. Musha and Prof. Mario J. Pinheiro will be publishing a book on electrogravitics including the electromagnetic propulsion systems, titled, “Physics of the Zero Point Field and Its Applications to Advanced Technology”, Nova Science Pub Inc. Publication date is Sept.25, 2012 (tomorrow).

To quote Dr. Musha:

“Space-time in a vacuum has generally been viewed as a transparent and ubiquitous empty continuum within which physical events take place. However quantum field theory and quantum electrodynamics views the vacuum as the sum total of all zero-point fluctuations of the vacuum electromagnetic field, arising from the continuous creation and annihilation of virtual particle pairs. It is this latter more contemporary view that is, for the first time, more fully explored in text form with Physics of the Zero Point Field. The scope of applications in this book range from the Casimir effect, the variation in zero-point energy at the boundaries of a region observable in nano-scale devices, to ideas for a proposed inertial drive as first described by Puthoff.”

Interstellar Black Hole Jokes

Posted by in category: fun

Here is my attempt at interstellar black hole jokes. With the 2nd and 3rd I was attempting humor with a minimum number of words. I’ve managed a 2 word joke. I hope you finds these funny and please contribute your version of these interstellar black hole (family friendly) jokes.

Debunking Laithwaite’s Critics

Posted by in category: physics

Pervious blog post in this debunking series

Recently I had an interesting discussion about Laithwaite’s Big Wheel demonstration.

Note that the late Professor Eric Laithwaite was Professor of Heavy Electrical Engineering at Imperial College, and inventor of the linear motor, and the maglev train technology which Germany and China have taken the lead. The poor Brits they missed out on their own invention.

The Big Wheel experiment is basically this. Attach a wheel to the end of a 3-ft (1 m) rod. Spin this wheel to 3,000 rpm or more. Then rotate this rod with the spinning wheel at the other end. The technical description is, rotate the spin vector.

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”.

Only One Interstellar Travel Community Will Succeed

Posted by in categories: engineering, finance, philosophy, physics, space

There four camps that comprise the present day interstellar travel community and only one camp will succeed.

The first camp, the conventional rocket camp, believes it is possible using conventional rockets (chemical, ion, nuclear or antimatter) to realize interstellar travel to our nearest star Alpha Centauri. One of the problems is the costs, estimated at an unthinkably large $238,596 billion and upwards. It is several thousand times greater if we choose to use antimatter.

Further, John Eades, a former senior scientist with CERN, in his March/April 2012 Skeptical Inquirer article “Antimatter Pseudoscience”, lays down the reasons why antimatter based propulsion will never be technologically feasible.

Black Hole of wealth. One down three to go.
