Peer-to-Peer Science: The Century-Long Challenge to Respond to Fukushima

Peer-to-Peer Science

The Century-Long Challenge to Respond to Fukushima

Emanuel Pastreich (Director)

Layne Hartsell (Research Fellow)

The Asia Institute

More than two years after an earthquake and tsunami wreaked havoc on a Japanese power plant, the Fukushima nuclear disaster is one of the most serious threats to public health in the Asia-Pacific, and the worst case of nuclear contamination the world has ever seen. Radiation continues to leak from the crippled Fukushima Daiichi site into groundwater, threatening to contaminate the entire Pacific Ocean. The cleanup will require an unprecedented global effort.

Initially, the leaked radioactive materials consisted of cesium-137 and 134, and to a lesser degree iodine-131. Of these, the real long-term threat comes from cesium-137, which is easily absorbed into bodily tissue—and its half-life of 30 years means it will be a threat for decades to come. Recent measurements indicate that escaping water also has increasing levels of strontium-90, a far more dangerous radioactive material than cesium. Strontium-90 mimics calcium and is readily absorbed into the bones of humans and animals.

The Tokyo Electric Power Company (TEPCO) recently announced that it lacks the expertise to effectively control the flow of radiation into groundwater and seawater and is seeking help from the Japanese government. TEPCO has proposed setting up a subterranean barrier around the plant by freezing the ground, thereby preventing radioactive water from eventually leaking into the ocean—an approach that has never before been attempted in a case of massive radiation leakage. TEPCO has also proposed erecting additional walls now that the existing wall has been overwhelmed by the approximately 400 tons per day of water flowing into the power plant.

But even if these proposals were to succeed, they would not constitute a long-term solution.

A New Space Race

Solving the Fukushima Daiichi crisis needs to be considered a challenge akin to putting a person on the moon in the 1960s. This complex technological feat will require focused attention and the concentration of tremendous resources over decades. But this time the effort must be international, as the situation potentially puts the health of hundreds of millions at risk. The long-term solution to this crisis deserves at least as much attention from government and industry as do nuclear proliferation, terrorism, the economy, and crime.

To solve the Fukushima Daiichi problem will require enlisting the best and the brightest to come up with a long-term plan to be implemented over the next century. Experts from around the world need to contribute their insights and ideas. They should come from diverse fields—engineering, biology, demographics, agriculture, philosophy, history, art, urban design, and more. They will need to work together at multiple levels to develop a comprehensive assessment of how to rebuild communities, resettle people, control the leakage of radiation, dispose safely of the contaminated water and soil, and contain the radiation. They will also need to find ways to completely dismantle the damaged reactor, although that challenge may require technologies not available until decades from now.

Such a plan will require the development of unprecedented technologies, such as robots that can function in highly radioactive environments. This project might capture the imagination of innovators in the robotics world and give a civilian application to existing military technology. Improved robot technology would prevent the tragic scenes of old people and others volunteering to enter into the reactors at the risk of their own wellbeing.

The Fukushima disaster is a crisis for all of humanity, but it is a crisis that can serve as an opportunity to construct global networks for unprecedented collaboration. Groups or teams aided by sophisticated computer technology can start to break down into workable pieces the immense problems resulting from the ongoing spillage. Then experts can come back with the best recommendations and a concrete plan for action. The effort can draw on the precedents of the Intergovernmental Panel on Climate Change, but it must go far further.

In his book Reinventing Discovery: The New Era of Networked Science, Michael Nielsen describes principles of networked science that can be applied on an unprecedented scale. The breakthroughs that come from this effort can also be used for other long-term programs such as the cleanup of the BP Deepwater Horizon oil spill in the Gulf of Mexico or the global response to climate change. The collaborative research regarding Fukushima should take place on a very large scale, larger than the sequencing of the human genome or the maintenance of the Large Hadron Collider.

Finally, there is an opportunity to entirely reinvent the field of public diplomacy in response to this crisis. Public diplomacy can move from a somewhat ambiguous effort by national governments to repackage their messaging to a serious forum for debate and action on international issues. As public diplomacy matures through the experience of Fukushima, we can devise new strategies for bringing together hundreds of thousands of people around the world to respond to mutual threats. Taking a clue from networked science, public diplomacy could serve as a platform for serious, long-term international collaboration on critical topics such as poverty, renewable energy, and pollution control.

Similarly, this crisis could serve as the impetus to make social networking do what it was supposed to do: help people combine their expertise to solve common problems. Social media could be used not as a means of exchanging photographs of lattes and overfed cats, but rather as an effective means of assessing the accuracy of information, exchanging opinions between experts, forming a general consensus, and enabling civil society to participate directly in governance. With the introduction into the social media platform of adequate peer review—such as that advocated by the Peer-to-Peer Foundation (P2P)—social media can play a central role in addressing the Fukushima crisis and responding to it. As a leader in the P2P movement, Michel Bauwens, suggests in an email, “peers are already converging in their use of knowledge around the world, even in manufacturing at the level of computers, cars, and heavy equipment.”

Here we may find the answer to the Fukushima conundrum: open the problem up to the whole world.

Peer-to-Peer Science

Making Fukushima a global project that seriously engages both experts and common citizens in the millions, or tens of millions, could give some hope to the world after two and a half years of lies, half-truths, and concerted efforts to avoid responsibility on the part of the Japanese government and international institutions. If concerned citizens in all countries were to pore through the data and offer their suggestions online, there could be a new level of transparency in the decision-making process and a flourishing of invaluable insights.

There is no reason why detailed information on radiation emissions and the state of the reactors should not be publicly available in enough detail to satisfy the curiosity of a trained nuclear engineer. If the question of what to do next comes down to the consensus of millions of concerned citizens engaged in trying to solve the problem, we will have a strong alternative to the secrecy that has dominated so far. Could our cooperation on the solution to Fukushima be an imperative to move beyond the existing barriers to our collective intelligence posed by national borders, corporate ownership, and intellectual property concerns?

A project to classify stars throughout the university has demonstrated that if tasks are carefully broken up, it is possible for laypeople to play a critical role in solving technical problems. In the case of Galaxy Zoo, anyone who is interested can qualify to go online and classify different kinds of stars situated in distant galaxies and enter the information into a database. It’s all part of a massive effort to expand our knowledge of the universe, which has been immensely successful and demonstrated that there are aspects of scientific analysis that does not require a Ph.D. In the case of Fukushima, if an ordinary person examines satellite photographs online every day, he or she can become more adept than a professor in identifying unusual flows carrying radioactive materials. There is a massive amount of information that requires analysis related to Fukushima, and at present most of it goes virtually unanalyzed.

An effective response to Fukushima needs to accommodate both general and specific perspectives. It will initially require a careful and sophisticated setting of priorities. We can then set up convergence groups that, aided by advanced computation and careful efforts at multidisciplinary integration, could respond to crises and challenges with great effectiveness. Convergence groups can also serve as a bridge between the expert and the layperson, encouraging a critical continuing education about science and society.

Responding to Fukushima is as much about educating ordinary people about science as it is about gathering together highly paid experts. It is useless for experts to come up with novel solutions if they cannot implement them. But implementation can only come about if the population as a whole has a deeper understanding of the issues. Large-scale networked science efforts that are inclusive will make sure that no segments of society are left out.

If the familiar players (NGOs, central governments, corporations, and financial institutions) are unable to address the unprecedented crises facing humanity, we must find ways to build social networks, not only as a means to come up with innovative concepts, but also to promote and implement the resulting solutions. That process includes pressuring institutions to act. We need to use true innovation to pave the way to an effective application of science and technology to the needs of civil society. There is no better place to start than the Internet and no better topic than the long-term response to the Fukushima disaster.

An Upside to Fukushima: Japan’s Robot Renaissance


Fukushima’s Second Anniversary…

Two years ago the international robot dorkosphere was stunned when, in the aftermath of the Tohoku Earthquake and Tsunami Disaster, there were no domestically produced robots in Japan ready to jump into the death-to-all-mammals radiation contamination situation at the down-melting Fukushima Daiichi nuclear power plant.

…and Japan is Hard at Work.
Suffice it to say, when Japan finds out its robots aren’t good enough — JAPAN RESPONDS! For more on how Japan has and is addressing the situation, have a jump on over to AkihabaraNews.com.

Oh, and here’s some awesome stuff sourced from the TheRobotReport.com:

Ten Commandments of Space

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.

Petition for Americium Emergency Stockpile

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.

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


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:


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.

Water, Bombs, WE CAN GO NOW

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.

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.

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.

Cosmic Ray Gorilla

http://www.sciencedaily.com/releases/2012/12/121231180632.htm

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.
