Water, Bombs, WE CAN GO NOW

Posted by in categories: asteroid/comet impacts, biotech/medical, business, defense, economics, education, engineering, ethics, existential risks, military, nuclear energy, nuclear weapons, policy, space, transparency

I was recently accused on another blog of repeating a defeatist mantra.

My “mantra” has always been WE CAN GO NOW. The solutions are crystal clear to anyone who takes a survey of the available technology. What blinds people is their unwillingness to accept the cost of making it happen.
There is no cheap.

Paul Gilster comments on his blog Centauri Dreams, concerning Radiation, Alzheimer’s Disease and Fermi;

“Neurological damage from human missions to deep space — and the study goes no further than the relatively close Mars — would obviously affect our planning and create serious payload constraints given the need for what might have to be massive shielding.”

Gravity Modification – What Is The Record?

Posted by in categories: business, defense, economics, education, lifeboat, particle physics, physics, policy, space, transparency

If, we as a community, are intending to accelerate the development of interstellar travel we have to glower at the record and ask ourselves some tough questions. First, what is the current record of the primary players? Second, why is everyone afraid to try something outside the status quo theories?

At the present time the primary players are associated with the DARPA funded 100-Year Starship Study, as Icarus Interstellar who is cross linked with The Tau Zero Foundation and Centauri Dreams is a team member of the 100YSS. I was surprised to find Jean-Luc Cambier on Tau Zero.

Gary Church recently put the final nail in the Icarus Interstellar‘s dreams to build a rocket ship for interstellar travel. In his post on Lifeboat, Cosmic Ray Gorilla Gary Church says “it is likely such a shield will massive over a thousand tons”. Was he suggesting that the new cost of an interstellar rocket ship is not 3.4x World GDP but 34x or 340x World GDP? Oops!

Let us look at the record. Richard Obousy of Icarus Interstellar and Eric Davis of Institute for Advanced Studies claimed that it was possible, using string theories to travel at not just c, the velocity of light but at 1E32c, or c multiplied by a 1 followed by 32 zeros. However, Lorentz-FitzGerald transformations show that anything with mass cannot travel faster than the velocity of light. Note that Lorentz-FitzGerald is an empirical observation which was incorporated into Einstein’s Special Theory of Relativity.

Gravity Modification – What Went Wrong?

Posted by in categories: business, chemistry, defense, education, engineering, physics, policy, scientific freedom, space, transparency

Recently, I met Josh Hopkins of Lockheed’s Advanced Programs, AIAA Rocky Mountain Region’s First Annual Technical Symposium (RMATS), October 26, 2012. Josh was the keynote speaker at this RMATS. Here is his presentation. After his presentation we talked outside the conference hall. I told him about my book, and was surprised when he said that two groups had failed to reproduce Podkletnov’s work. I knew one group had but a second? As we parted we said we’d keep in touch. But you know how life is, it has the habit of getting in the way of exciting research, and we lost touch.

About two weeks ago, I remembered, that Josh had said that he would provide some information on the second group that had failed to reproduce Podkletnov’s work. I sent him an email, and was very pleased to hear back from him and that the group’s finding had been published under the title “Gravity Modification by High-Temperature Semiconductors”. The authors were C. Woods, S. Cooke, J. Helme & C. Caldwell. Their paper was published in the 37th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 8–11 July 2001, Salt Lake City, Utah. I bought a copy for the AIAA archives, and read it, reread it, and reread it.

Then I found a third team they published their lack of findings “Gravity Modification Experiments Using a Rotating Superconducting Disk and Radio Frequency Fields”. The authors were G. Hathaway, B. Cleveland and Y. Bao. Published in Physica C, 2003.

Both papers focused on attempting to build a correct superconducting disc. At least Wood et al said “the tests have not fulfilled the specified conditions for a gravity effect”. The single most difficult thing to do was to build a bilayered superconducting disc. Woods et al tried very hard to do so. Reading through Hathaway et all paper suggest that they too had similar difficulties. Photo shows a sample disc from Woods’ team. Observe the crack in the middle.

2012 was Great and may 2013 be Extraordinary

Posted by in categories: business, education, engineering, ethics, fun, human trajectories, lifeboat, media & arts, open access, open source, policy, scientific freedom, space, transparency

May peace break into your home and may thieves come to steal your debts.
May the pockets of your jeans become a magnet for $100 bills.
May love stick to your face like Vaseline and may laughter assault your lips!
May happiness slap you across the face and may your tears be that of joy
May the problems you had, forget your home address!

In simple words .….….……May 2013 be EXTRAORDINARY … the best year of your life!!! Simply the best New Year greeting anyone has sent to me. This was from Robert White of Extraordinary People.

This morning I checked the Lifeboat stats for 2012. When I started blogging for Lifeboat at the end of July, we ended July 2012 with 42,771 unique visitors. We closed 2012 with 90,920 unique visitors for the month December. Wow! Our blogging has become more relevant, and more thought provoking. As a community of bloggers (with the exception of one) we have moved away from the 3 Cs of pseudoscience. Clouding the field. Confusing the public’s perception. Chasing away talent.

How did we do this? By backing up our discussions with hard facts, robust debate and real numbers. From years if not decades of investigation in our field of research. By speaking from our own unique experience. By sharing that unique experience with our readers.

Gravity Modification – New Tools

Posted by in categories: business, cosmology, defense, education, engineering, general relativity, particle physics, philosophy, physics, policy, space

To understand why gravity modification is not yet a reality, let’s analyze other fundamental discoveries/inventions that changed our civilization or at least the substantially changed the process of discovery. There are several that come to mind, the atomic bomb, heavier than air manned flight, the light bulb, personal computers, and protein folding. There are many other examples but these are sufficient to illustrate what it takes. Before we start, we have to understand four important and related concepts.

(1) Clusters or business clusters, first proposed by Harvard prof. Michael Porter, “a business cluster is a geographic concentration of interconnected businesses, suppliers, and associated institutions in a particular field. Clusters are considered to increase the productivity with which companies can compete, nationally and globally”. Toyota City which predates Porter’s proposal, comes to mind. China’s 12 new cities come to mind, and yes there are pro and cons.

The Fabulous Spaceport Colorado (Part 3)

Posted by in categories: business, defense, economics, education, engineering, geopolitics, policy, space

Last month a colleague of mine and I visited with Dennis Heap, Executive Director of the National Front Range Airport, at Watkins, CO, the location of the future Spaceport Colorado, and Colorado’s contribution to getting into space. Here is Part 3.

In my last post I had mentioned that there were 2 business models for spaceports. I’ll name the first Sweden-America model after spaceports Sweden & America. The second, I’ll name Colorado-Singapore model after (yet to be) spaceports Colorado & Singapore.

The Sweden-America model basic premise is that spaceport ought to be built in remote locations, and then a hinterland economy is eventually built around the spaceport. This approach was originally driven by safety concerns and the need for a rocket range or vacant land for launching rockets to crash back to.

The basic premise of the Colorado-Singapore model is that launch vehicles are safe and that spaceports ought to be built close to centers of commerce and intermodal transportation networks. That is, spaceports are to be built in an existing hinterland economy.

The Kline Directive: Technological Feasibility (3b)

Posted by in categories: cosmology, defense, economics, education, engineering, general relativity, particle physics, physics, scientific freedom, space

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, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationships, and Technological Feasibility.

In a previous post on Technological Feasibility I had stated that a quick and dirty model shows that we could achieve velocity of light c by 2151 or the late 2150s. See table below.

Year Velocity (m/s) % of c
2200 8,419,759,324 2808.5%
2152 314,296,410 104.8%
2150 274,057,112 91.4%
2125 49,443,793 16.5%
2118 30,610,299 10.2%
2111 18,950,618 6.3%
2100 8,920,362 3.0%
2075 1,609,360 0.5%
2050 290,351 0.1%
2025 52,384 0.0%

That is, at the current rate of technological innovation we could as a civilization reach light speed in about 140 years. More importantly we could not even reach anywhere near that within the next 100 years. Our capability would be 6.3% of c.

The Lorentz-Fitzgerald transformation informs us light speed would require an infinite amount of energy (i.e. more than there is in the Universe!), thereby highlighting the weaknesses in these types of technological forecasting methods. But these models still serve a purpose. They provide some guidance as to what is possible and when. The operative word is guidance.

Solving Complex Problems

Posted by in categories: complex systems, education, homo sapiens

Solving complex problems is one of the defining features of our age. The ability to harness a wide range of skills and synthesise diverse areas of knowledge is essentially integral to a researcher’s DNA. It is interesting to read how MIT first offered a class in ‘Solving Complex Problems’ back in 2000. Over the course of a semester students attempt to ‘imagineer’ a solution to a highly complex problem. There is a great need for this type of learning in our educational systems. If we are to develop people who can tackle the Grand Challenges of this epoch then we need to create an environment in which our brains are allowed to be wired differently through exposure to diverse areas of knowledge and methods of understanding reality across disciplines.

When I look at my niece who is only 4 years old I wonder how I can give her the best education, and prepare her to meet the challenges of this world, as she grows up in a world which fills my heart with great anxiety. It is fascinating to read about different educational approaches from Steiner education to Montessori education to developing curriculums and school design upon cognitive neuroscience and educational theory. However when I look at the thinkers of insight, and contrast it with educational policy in the developed world, there is quite clearly a huge disconnect between politics and science.

We need to develop a culture of complexity if we are to develop the ability and insight to solve complex problems. When we look at the world from the perspective of complexity it builds a very different mindset in how we think about the world, and how we go about trying to understand the world, and ultimately how we go about solving problems.

The Kline Directive: Technological Feasibility (3a)

Posted by in categories: cosmology, defense, education, engineering, general relativity, particle physics, physics, policy, scientific freedom, space

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, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationships, and Technological Feasibility.

My apologies to my readers for this long break since my last post of Nov 19, 2012. I write the quarterly economic report for a Colorado bank’s Board of Directors. Based on my quarterly reports to the Board, I gave a talk Are We Good Stewards? on the US Economy to about 35 business executives at a TiE Rockies’ Business for Breakfast event. This talk was originally scheduled for Dec 14, but had moved forward to Nov 30 because the original speaker could not make the time commitment for that day. There was a lot to prepare, and I am very glad to say that it was very well received. For my readers who are interested here is the link to a pdf copy of my slides to Are We Good Stewards?

Now back to interstellar physics and the Kline Directive. Let’s recap.

In my last four posts (2c), (2d), (2e) & (2f) I had identified four major errors taught in contemporary physics. First, to be consistent (2c) with Lorentz-Fitzgerald and Special Theory of Relativity, elementary particles contract as their energy increases. This is antithetical to string theories and explains why string theories are becoming more and more complex without discovering new empirically verifiable fundamental laws of Nature.
