Activelink Power Loader Gives HAL Some Competition, but Who’s Going to Fukushima?

Posted by in categories: biotech/medical, defense, military, nuclear energy, robotics/AI


LEFT: Activelink Power Loader Light — RIGHT: The Latest HAL Suit

New Japanese Exoskeleton Pushing into HAL’s (potential) Marketshare
We of the robot/technology nerd demo are well aware of the non-ironically, ironically named HAL (Hybrid Assistive Limb) exoskeletal suit developed by Professor Yoshiyuki Sankai’s also totally not meta-ironically named Cyberdyne, Inc. Since its 2004 founding in Tsukuba City, just north of the Tokyo metro area, Cyberdyne has developed and iteratively refined the force-amplifying exoskeletal suit, and through the HAL FIT venture, they’ve also created a legs-only force resistance rehabilitation & training platform.

Joining HAL and a few similar projects here in Japan (notably Toyota’s & Honda’s) is Kansai based & Panasonic-owned Activelink’s new Power Loader Light (PLL). Activelink has developed various human force amplification systems since 2003, and this latest version of the Loader looks a lot less like its big brother the walking forklift, and a lot more like the bottom half & power pack of a HAL suit. Activelink intends to connect an upper body unit, and if successful, will become HAL’s only real competition here in Japan.
And for what?

Well, along with general human force amplification and/or rehab, this:

A Revolution in Physics?

A Revolution in Physics and Cosmology

by Otto E. Rossler, Faculty of Natural Sciences, University of Tubingen, Germany

A deterministic 2-particle system interacting with a fixed third particle (the wall of a confining T-tube) shows two kinds of behavior never seen in a deterministic system before: Dissipative and antididissipative behavior in both directions of time (dependent on the sign of the force law). Dissipative behavior occurs in both directions of time when the system is started from non-selected far-from-equipartition initial conditions while the potential (giving rise to the force law) is Newtonian–repulsive. Antidissipative behavior occurs (in both directions of time) when the system is started from non-selected far-from-equipartition initial conditions while the potential is Newtonian–attractive.

“Entropic” behavior had not been demonstrated before in a deterministic system. Now, both “entropic” and “ectropic” behavior are described under deterministic-chaos conditions. The numerical simulations are due to Klaus Sonnleitner (2010) and, independently, Ramis Movassagh (2011) who also provided an analytical derivation.

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.

Einstein Mining

Einstein Mining

Otto E. Rossler, Faculty of Science, University of Tubingen, Germany

The young Einstein was the most fertile scientific mind of history. He first saw the observer-private nature of simultaneity, a consequence of the global constancy of the speed of light c valid in Maxwell’s equation. He then spotted the twin miracle (“paradox”): that a returned twin clock is younger than its stay-put sibling. The transversal Doppler effect described in the same 1905 paper was equally new. At the end of this miraculous year stood the improved Weber law (E exactly equal m times c-square) destined to become tragically consequential when Lise Meitner would recall its strength 34 years into the future. Two years after the miraculous year, there followed Einstein’s biggest discovery in the present author’s mind: the gravitational clock slowdown near the bottom of a constantly accelerating rocketship compared to a twin clock in its tip. It implies a second twin paradox (spending time downstairs lets you stay younger in Alan Lightman’s phrase).

This bundle of subsequently observationally confirmed predicted effects is an eternal heritage. Maxwell’s advice: go back to the origin of an already discovered gold vein since it is there that others inevitably originate is still valid. This is the excuse for the new notion of “Einstein mining.”

Explaining Space Travel

I recently posted this on the only two other sites that will allow me to express my opinions;

I see the problem as one of self similarity; trying to go cheap being the downfall of all these schemes to work around human physiology.

When I first became interested in space travel several years ago I would comment on a couple blogs and find myself constantly arguing with private space proponents- and saying over and over again, “there is no cheap.” I was finally excommunicated from that bunch and banned from posting. They would start calling me an idiot and other insults and when I tried to return the favor the moderator would block my replies. The person who runs those two sites works for a firm promoting space tourism- go figure.

The problem is that while the aerospace industry made some money off the space program as an outgrowth of the military industrial complex, it soon became clear that spaceships are hard money- they have to work. The example of this is the outrage over the Apollo 1 fire and subsequent oversight of contractors- a practice which disappeared after Apollo and resulted in the Space Shuttle being such a poor design. A portion of the shuttle development money reportedly went under the table into the B-1 bomber program; how much we will never know. Swing wings are not easy to build which is why you do not see it anymore; cuts into profits.

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.

Cosmic Ray Gorilla

Excerpt: “Galactic cosmic radiation poses a significant threat to future astronauts,” said M. Kerry O’Banion, M.D., Ph.D., a professor in the University of Rochester Medical Center (URMC) Department of Neurobiology and Anatomy and the senior author of the study. “The possibility that radiation exposure in space may give rise to health problems such as cancer has long been recognized. However, this study shows for the first time that exposure to radiation levels equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer’s disease.”

It appears when Eugene Parker wrote “Shielding Space Travelers” in 2006 he was right- and all the private space sycophants claiming radiation mitigation is trivial are wrong.

Only a massive water shield a minimum of 14 feet thick and massing 400 tons for a small capsule can shield human beings in deep space on long duration missions. And since a small capsule will not have sufficient space to keep a crew psychologically healthy on a multi-year journey it is likely such a shield will massive over a thousand tons.
