The Rocky Mountain chapter of the American Institute of Astronautics & Aeronautics (AIAA) will be having their 2nd Annual Technical Symposium, October 25 2013. The call for papers ends May 31 2013. I would recommend submitting your papers. This conference gives you the opportunity to put your work together in a cohesive manner, get feedback and keep your copyrights, before you write your final papers for journals you will submitting to. A great way to polish your papers.
Fabrizio Brocca from Italy wanted to know more about the Ni field shape for a rotating-spinning-disc. Finally, a question from someone who has read my book. This is not easy to explain over email, so I’m presenting the answers to his questions at this conference, as ‘The Mechanics of Gravity Modification’. That way I can reach many more people. Hope you can attend, read the book, and have your questions ready. I’m looking forward to your questions. This is going to be a lively discussion, and we can adjourn off conference.
My intention for using this forum to explain some of my research is straight forward. There will be (if I am correct) more than 100 aerospace companies in attendance, and I am expecting many of them will return to set up engineering programs to reproduce, test and explore gravity modification as a working technology.
Fabrizio Brocca I hope you can make it to Colorado this October, too.
1. Thou shalt first guard the Earth and preserve humanity.
Impact deflection and survival colonies hold the moral high ground above all other calls on public funds.
2. Thou shalt go into space with heavy lift rockets with hydrogen upper stages and not go extinct.
The human race can only go in one of two directions; space or extinction- right now we are an endangered species.
3. Thou shalt use the power of the atom to live on other worlds.
Nuclear energy is to the space age as steam was to the industrial revolution; chemical propulsion is useless for interplanetary travel and there is no solar energy in the outer solar system.
4. Thou shalt use nuclear weapons to travel through space.
Physical matter can barely contain chemical reactions; the only way to effectively harness nuclear energy to propel spaceships is to avoid containment problems completely- with bombs.
5. Thou shalt gather ice on the Moon as a shield and travel outbound.
The Moon has water for the minimum 14 foot thick radiation shield and is a safe place to light off a bomb propulsion system; it is the starting gate.
6. Thou shalt spin thy spaceships and rings and hollow spheres to create gravity and thrive.
Humankind requires Earth gravity and radiation to travel for years through space; anything less is a guarantee of failure.
7. Thou shalt harvest the Sun on the Moon and use the energy to power the Earth and propel spaceships with mighty beams.
8. Thou shalt freeze without damage the old and sick and revive them when a cure is found; only an indefinite lifespan will allow humankind to combine and survive. Only with this reprieve can we sleep and reach the stars.
9. Thou shalt build solar power stations in space hundreds of miles in diameter and with this power manufacture small black holes for starship engines.
10. Thou shalt build artificial intellects and with these beings escape the death of the universe and resurrect all who have died, joining all minds on a new plane.
I continue to survey the available technology applicable to spaceflight and there is little change.
The remarkable near impact and NEO on the same day seems to fly in the face of the experts quoting a probability of such coincidence being low on the scale of millenium. A recent exchange on a blog has given me the idea that perhaps crude is better. A much faster approach to a nuclear propelled spaceship might be more appropriate.
Unknown to the public there is such a thing as unobtanium. It carries the country name of my birth; Americium.
A certain form of Americium is ideal for a type of nuclear solid fuel rocket. Called a Fission Fragment Rocket, it is straight out of a 1950’s movie with massive thrust at the limit of human G-tolerance. Such a rocket produces large amounts of irradiated material and cannot be fired inside, near, or at the Earth’s magnetic field. The Moon is the place to assemble, test, and launch any nuclear mission.
Such Fission Fragment propelled spacecraft would resemble the original Tsolkovsky space train with a several hundred foot long slender skeleton mounting these one shot Americium boosters. The turn of the century deaf school master continues to predict.
Each lamp-shade-spherical thruster has a programmed design balancing the length and thrust of the burn. After being expended the boosters use a small secondary system to send them into an appropriate direction and probably equipped with small sensor packages, using the hot irradiated shell for an RTG. The Frame that served as a car of the space train transforms into a pair of satellite panels. Being more an artist than an *engineer, I find the monoplane configuration pleasing to the eye as well as being functional. These dozens and eventually thousands of dual purpose boosters would help form a space warning net.
The front of the space train is a large plastic sphere partially filled filled with water sent up from the surface of a a Robotic Lunar Polar Base. The Spaceship would split apart on a tether to generate artificial gravity with the lessening booster mass balanced by varying lengths of tether with an intermediate reactor mass.
These piloted impact threat interceptors would be manned by the United Nations Space Defense Force. All the Nuclear Powers would be represented.…..well, most of them. They would be capable of “fast missions” lasting only a month or at the most two months. They would be launched from underground silos on the Moon to deliver a nuclear weapon package towards an impact threat at the highest possible velocity and so the fastest intercept time. These ships would come back on a ballistic course with all their boosters expended to be rescued by recovery craft from the Moon upon return to the vicinity of Earth.
The key to this scenario is Americium 242. It is extremely expensive stuff. The only alternative is Nuclear Pulse Propulsion (NPP). The problem with bomb propulsion is the need to have a humungous mass for the most efficient size of bomb to react with.
The Logic Tree then splits again with two designs of bomb propelled ship; the “Orion” and the “Medusa.” The Orion is the original design using a metal plate and shock absorbing system. The Medusa is essentially a giant woven alloy parachute and tether system that replaces the plate with a much lighter “mega-sail.” In one of the few cases where compromise might bear fruit- the huge spinning ufo type disc, thousands of feet across, would serve quite well to explore, colonize, and intercept impact threats. Such a ship would require a couple decades to begin manufacture on the Moon.
Americium boosters could be built on earth and inserted into lunar orbit with Human Rated Heavy Lift Vehicles (SLS) and a mission launched well within a ten-year apollo type plan. But the Americium Infrastructure has to be available as a first step.
Would any of my hundreds of faithful followers be willing to assist me in circulating a petition?
*Actually I am neither an artist or an engineer- just a wannabe pulp writer in the mold of Edgar Rice Burroughs.
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 newPower 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:
福島第一原子力発電所事故 — Fukushima Daiichi Nuclear Disaster Site
Fukushima Cleanup & Recovery: Heavy with High-Rads As with Cyberdyne’s latest radiation shielded self-cooling HAL suit (the metallic gray model), Activelink’s PLL was ramped up after the 2011 Tohoku earthquake, tsunami, and resulting disaster at the Fukushima Daiichi Power Plant. Cleanup at the disaster area and responding to future incidents will of course require humans in heavy radiation suits with heavy tools possibly among heavy debris.While specific details on both exoskeletons’ recent upgrades and deployment timeline and/or capability are sparse, clearly the HAL suit and the PLL are conceptually ideal for the job. One assumes both will incorporate something like 20-30KG/45-65lbs. per limb of force amplification along with fully supporting the weight of the suit itself, and like HAL, PLL will have to work in a measure of radiological shielding and design consideration. So for now, HAL is clearly in the lead here.
Exoskeleton Competition Motivation Situation Now, the HAL suit is widely known, widely deployed, and far and away the most successful of its kind ever made. No one else in Japan — in the world — is actually manufacturing and distributing powered exoskeletons at comparable scale. And that’s awesome and all due props to Professor Sankai and his team, but in taking stock of the HAL project’s 8 years of ongoing development, objectively one doesn’t see a whole lot of fundamental advancement. Sure, lifting capacity has increased incrementally and the size of the power source & overall bulk have decreased a bit. And yeah, no one else is doing what Cyberdyne’s doing, but that just might be the very reason why HAL seems to be treading water — and until recently, e.g., Activelink’s PLL, no one’s come along to offer up any kind of alternative.
Digressively Analogizing HAL with Japan & Vice-Versa Maybe What follows is probably anecdotal, but probably right: See, Japanese economic and industrial institutions, while immensely powerful and historically cutting-edge, are also insular, proud — and weirdly — often glacially slow to innovate or embrace new technologies. With a lot of relatively happy workers doing excellent engineering with unmatched quality control and occasional leaps of innovation, Japan’s had a healthy electronics & general tech advantage for a good long time. Okay but now, thorough and integrated globalization has monkeywrenched the J-system, and while the Japanese might be just as good as ever, the world has caught up. For example, Korea’s big two — Samsung & LG — are now selling more TVs globally than all Japanese makers combined. Okay yeah, TVs ain’t robots, but across the board competition has arrived in a big way, and Japan’s tech & electronics industries are faltering and freaking out, and it’s illustrative of a wider socioeconomic issue. Cyberdyne, can you dig the parallel here?
Back to the Robot Stuff: Get on it, HAL/Japan — or Someone Else Will A laundry list of robot/technology outlets, including Anthrobotic & IEEE, puzzled at how the first robots able to investigate at Fukushima were the American iRobot PackBots & Warriors. It really had to sting that in robot loving, automation saturated, theretofore 30% nuclear-powered Japan, there was no domestically produced device nimble enough and durable enough to investigate the facility without getting a radiation BBQ (the battle-tested PackBots & Warriors — no problem). So… ouch?
For now, HAL & Japan lead the exoskeletal pack, but with a quick look at Andra Keay’s survey piece over at Robohub it’s clear that HAL and the PLL are in a crowded and rapidly advancing field. So, if the U.S. or France or Germany or Korea or the Kiwis or whomever are first to produce a nimble, sufficiently powered, appropriately equipped, and ready-for-market & deployment human amplification platform, Japanese energy companies and government agencies and disaster response teams just might add those to cart instead. Without rapid and inspired development and improvement, HAL & Activelink, while perhaps remaining viable for Japan’s aging society industry, will be watching emergency response and cleanup teams at home with their handsome friend Asimo and his pet Aibo, wondering whatever happened to all the awesome, innovative, and world-leading Japanese robots.
It’ll all look so real on a 80-inch Samsung flat-panel HDTV.

This piece originally appeared at Anthrobotic.com on January 17, 2013.
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.”
Massive shielding. This is the game changer. The showstopper. The sea change. The paradigm shift. The cosmic ray gorilla. Whatever you want to call it, it is the reality that most of what we are familiar with concerning human space flight is not going to work in deep space. Massive Shielding=Nuclear Propulsion=Bombs M=N=B We have to transport nuclear materials to the Moon where we can light off a nuclear propulsion system. The Moon is where the ice-derived Water to fill up a Massive radiation shield is to be found. Massive Shield=Water=Lunar Base M=W=L Sequentially: L=W=M=N=B So, first and last, we need an HLV to get to this Lunar Base (where the Water for the shield is) and we need to safely transport Nuclear material there (and safely assemble and light off the Bombs to push the shield around).
Radiation shielding is the first determining factor in spaceship design and this largely determines the entire development of 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.
The easy money of cold war toys has since defeated any move by industry to take up the cause of space exploration. No easy money in spaceships. People who want something for nothing rarely end up with anything worth anything. Trying to find cheap ways around furnishing explorers with the physcial conditions human beings evolved in is going to fail. On the other hand if we start with a baseline of one gravity and Earth level radiation we are bound to succeed.
The engineering solutions to this baseline requirement are as I have already detailed; a tether for gravity and a massive moonwater shield with bomb propulsion. That is EXACTLY how to do it and I do not see any one else offering anything else that will work- just waffling and spewing about R&D. We have been doing R&D for over half a century. It is a reason to go that is supposedly lacking.
When that crater in Mexico was discovered in 1980 the cold war was reaching it’s crescendo and the massive extinction it caused was overshadowed by the threat of nuclear weapons. Impact defense is still the only path to all that DOD money for a Moon base.
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.
This mass may seem to make Human Space Flight Beyond Earth and Lunar Orbit (HSF-BELO) impractical but in fact it is not an obstacle but an enabler. Nuclear Pulse Propulsion using bombs to push a spaceship to the outer solar sytem becomes more efficient the larger the ship and this amount of water is useful in a closed loop life support system.
Lighting off bombs in the Earth’s magnetosphere is not acceptable and this points to the Moon as the obvious place to launch nuclear missions and also to acquire the water for radiation shielding. The Space Launch System (SLS) is the human-rated Heavy Lift Vehicle (HLV) with a powerful escape system that can safely transport the required fissionables to the Moon.
2013 may be the year of the comet and the year of the spaceship if the two goals of protecting the planet from impacts and establishing off world colonies are finally recognized as vital to the survival of humankind.
A happy new year to the human race from it’s most important member; me. Since self-worship seems to be the theme of the new American ideal I had better get right with me.
With my government going over the fiscal cliff it would appear that the damned soul of Ayn Rand is exerting demonic influence on the political system through worship of the individual. The tea party has the Republicans terrified of losing their jobs. Being just like me, those individuals consider themselves the most important person on the planet- so I cannot fault them.
As Ayn Rand believed, “I will not die, it’s the world that will end”, so who cares about the collective future of the human race? Towards the end of 2013 the heavens may remind us the universe does not really care about creatures who believe themselves all important. The choice may soon be seen clearly in the light of the comet’s tail; the glorification of the individual and the certain extinction of our race, or the acceptance of a collective goal and our continued existence.
Ayn Rand made her choice but most of us have time to choose more wisely. I pray for billions, tens and hundreds of billions of dollars- for a Moonbase.
I am not one of the Earth is overpopulated crowd. We could have a high quality of life for every man, woman and child on this planet if we did not, as a species, spend most of our resources pandering to moral weakness and cravings for profit. The myth of scarcity is a smokescreen to obscure the reality of greed and ignorance. Which is why people like Gerard K. O’Neill sought to improve the human condition with space colonies.
We need to go into space to first safeguard the Earth from impacts and the human race from extinction, and along with these missions to spread life into the universe through colonization. None of those three things has anything to do with getting filthy rich or intimidating other nations with our firepower so we can steal their resources. Which is why it has not happened.
Happy New Year with hopes for a more enlightened public.
Happy new year to my Wife, my Daughter, my Father, and to those who give a damn about next year even if they will not be there.
A half century after being developed, nuclear pulse propulsion remains the only practical system of interplanetary travel. What is required to launch a bomb propelled mission to the outer solar system? Well, first you need.…..bombs.
There is no shortage of bomb material on planet Earth. The problem is lack of a vehicle that can get this material to the nearest place a nuclear mission can be launched; the Moon. For over a quarter of a century a launch vehicle capable of sending significant payloads (and people) to the Moon has been lacking. The Space Transportation System, aka the space shuttle, was a dead end as far as exploration due to the lack of funding for a Sidemount cargo version.
Only this human rated Heavy Lift Vehicle (HLV) with a powerful escape tower will be suitable for transporting survivable packaged fissionables to the Moon. It is not only the fissionables that are required; hundreds of tons of water from lunar ice deposits are necessary to fill the radiation shield for any such Human Space Flight Beyond Earth Lunar Orbit (HSF-BELO).
Eventually lunar resources can be used to actually construct atomic spaceships and also the thorium reactors necessary to power colonies in the outer system. It is the establishment of a beam propulsion infrastructure that will finally open up the solar system to large scale development. This will require a massive infrastructure on the Moon. Such a base will serve as insurance against an extinction level event wiping out our species. As such it deserves a full measure of DOD funding. Like that trillion dollars that is going to be spent on the F-35 stealth fighter over the next half century.
Only monthly Heavy Lift Vehicle launches of payloads to the Moon can be considered as a beginning to a true space program- where Apollo left off. There is no cheap and there is no flexible path.
It was on a long-haul flight many months ago that I recalled a visit to the National Air and Space Museum [1] to a fellow passenger whom I struck up conversation with. Asking if I could recommend somewhere to visit in Washington DC, I recounted how I had spent an entire day amazing at the collection of historic aircraft and spacecraft on my only visit to that city fifteen years or so previous as a young adult — and as always a kid at heart.
Seeing the sheer scale of the F-1 engine for the Saturn 5 rocket first hand, stepping inside an Apollo command module identical to those used during the Apollo program, not to mention seeing full life-size replicas of the Lunar Roving Vehicle, an Apollo Lunar Module and for some reason what seemed most surreal to me… the Viking 1 Lander. This was enchantment.
However, for all the amazement that such a museum can provide, it is also a saddening reminder that what once was the forefront of human ambition and endeavor has now been largely resigned to history. NASA budgets are cut annually [2] whilst military expenditure takes ever more precedence. A planned six percent budget decrease in 2013 is the equivalent savings to three hours of the Iraq and Afghanistan Wars. Instead of reaching to explore outer-space we are encouraged to get excited about the equivalent billions [3] invested on science exploring the subatomic inner-space world. Meanwhile, we tend to forget that the ambitions of space exploration are not just to satisfy some wide-eyed childhood yearning to explore, but the serious and sobering prospect of needing to ensure that we as a species can eventually colonize to other worlds and ensure we are not counting down the days to our extinction on an ever-more-precarious planetary solitude.
In the face of such indifference, such concepts of lifeboats have become marginalized to what is perceived to be a realm solely for loons and dreamers, or ‘space cadets’ as we used to call them back in the days of school. The trillion dollar question really is what it takes to redirect all that military investment into science & exploration instead. It is down to credibility. Governments shy away from investing public funds when there is a lack of credibility.
It was an easy sell to the public to invest in the military after the tragic events of 9/11 and terrorist threats which were presented largely by propaganda/disinformation to the public as an existential risk to the free world. The purse strings opened and an unforgivable amount of expenditure was invested on the military in the subsequent years. Let us hope that it does not take unprecedented natural disasters [4] to awaken the world to the fact that it is nature which poses much greater existential risks to the survival of our society in the long-term.
