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.

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.

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:

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.”

Explaining Space Travel

Posted by in categories: asteroid/comet impacts, biological, defense, engineering, ethics, existential risks, finance, geopolitics, habitats, military, nuclear energy, nuclear weapons, space, transparency

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.

Cosmic Ray Gorilla

Posted by in categories: asteroid/comet impacts, biotech/medical, defense, ethics, events, existential risks, futurism, habitats, military, nuclear energy, nuclear weapons, policy, space, sustainability, transparency

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.

Forty Tons of Plutonium for Bomb Propulsion?

Posted by in categories: defense, engineering, existential risks, military, nuclear energy, nuclear weapons, space

http://news.yahoo.com/nowhere-japans-growing-plutonium-stockpile-064038796.html

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.

Now we wait on the SLS.

The Kline Directive: Technological Feasibility (2c) … continued

Posted by in categories: education, engineering, general relativity, nanotechnology, nuclear energy, particle physics, philosophy, physics, policy, scientific freedom, space

I was about to discuss the third of three concepts, but thought a look back would be appropriate at this time. In my earlier post I had shown that the photon/particle wave function could not be part of the photon/particle as this would violate the empirical Lorentz-Fitzgerald transformations and therefore, Einstein’s Special Theory of Relativity. The wave function is only the photon/particle’s disturbance of the spacetime it is in, and therefore explains why photons/particles have wave properties. They don’t. They disturb spacetime like a pebble dropped into a pond. The pond’s ripples are not the pebble.

In the recent findings, Dr. Alberto Peruzzo, University of Bristol (UK) the lead author of the paper and quoting “The measurement apparatus detected strong nonlocality, which certified that the photon behaved simultaneously as a wave and a particle in our experiment, … This represents a strong refutation of models in which the photon is either a wave or a particle.” This is a very important finding and another step in the progress of science towards a better understanding of our Universe.

Those of you who have been following my blog posts will recognize that this is empirical validation using single structure test that shows that both wave and particle properties occur together. What is required next, to be empirically rigorous, is to either confirm or deny that this wave function is a spacetime disturbance. For that we require a dual structure test.

If this wave function is a spacetime disturbance, then Einstein’s Special Theory of Relativity is upheld, and we would require a major rethink of quantum physics or the physics of elementary particles. If this wave function is a not spacetime disturbance but part of the particle structure, then there is an empirical exception to the Lorentz-Fitzgerald transformation and we would require a rethink of Einstein’s Special Theory of Relativity.

Radioactive Pollution: Fishing for Answers off Fukushima

Posted by in categories: engineering, nuclear energy, policy, sustainability, treaties

A recent article in Science Daily reported on efforts to measure Cesium-137 and Cesium-134 in bottom dwelling fish off the east coast of Japan to understand the lingering effects and potential public health implications. As the largest accidental release of radiation to the ocean in history, it is not surprising that many demersal fish are found above the limits for seafood consumption. What is more significant is that the contamination in almost all classifications of fish are not declining — suggesting that contaminated sediment on the seafloor could be providing a continuing source. This raises a concern that fallouts from any further nuclear accidents would aggregate over time.

One would question if the IAEA is taking a strong enough position on the permitted location of nuclear power stations. It perplexes me that the main objections to Iran attaining nuclear power are strategic/military. Whilst Iran is not at risk to the threat of tsunamis as Japan is, Iran is one of the most seismically active countries in the world, where destructive earthquakes often occur. This is because it is crossed by several major fault lines that cover at least 90% of the country. How robust are nuclear power stations to a major quake? The IAEA needs to expand its role to advise countries on what regions it would be unsuitable to build nuclear power stations — such as Iran and Japan. Otherwise we are risking a lasting environmental impact to eventually occur — it is only a matter of time.

How the Diablo Canyon nuclear plant, which sits just miles away from the notoriously active San Andreas fault was allowed to be located there let alone operate for a year and half with its emergency systems disabled (according to a 2010 safety review by the federal Nuclear Regulatory Commission). It seems as if there’s a missing link worldwide between the IAEA and regional planning authorities. Or perhaps it is simply down to responsible government.
