This essay was originally posted last year and is now back with small changes. Enjoy.

The first decade of the 21st century ended with human space flight nowhere near to fulfilling the predictions made at the beginning of the space age. Not even close. Just as the Vietnam war robbed the space exploration budget, the end of the century found vast public funds, a truly mind boggling amount of treasure, spent on the cold war toys that have yielded guaranteed huge profits for the military industrial complex. Many of these incredibly expensive weapon systems do not work as advertised and very few of them have any application in the present war on terror. 911 did not stop the money flowing to new super fighter planes and missiles designed to shoot down other missiles. The promise of space was in truth sacrificed for the profits of the weapons industry. The expected moon bases and colonies on Mars were never funded and no human being has escaped earth orbit since the last Apollo mission. The underfunded space shuttle completely failed to provide the cheap lift and multi-mission capability that was never really possible to achieve. The showpiece International Space Station is little more than a 100 billion dollar collection of tin cans flying in endless circles.

Over a quarter century wasted and the human race seems in large part to have accepted the end of the space age. Despite a collection of old and new inferior lift vehicles incapable of accelerating a spacecraft to escape velocity, there is endless hype concerning the privatization of space and the bright future these for profit enterprises will bring about. The single point of failure in these schemes is the false miracle of fuel depots in space. These orbital gas stations will supposedly enable all the missions that previously could only be accomplished by a Heavy Lift Vehicles like the Saturn V. Cryo fuel storage and transfer is at this time a myth and has never even been attempted due to the extreme difficulties involved. It is simply a smoke screen to disguise defeat. We are not going anywhere if we stay on this path. The only hope for human space flight is the realization that deep space travel may at any time mean the difference between humankind surviving or disappearing forever. If this truth cannot unlock the vast resources required then we are sealing our collective fate. The Spaceship is the only insurance against extinction. Safeguarding the entire human race is the ultimate military mission, yet is completely ignored by our leaders and the defense industry. The inevitable asteroid or comet impact and the threat of a 100 percent lethal plague are with us right now. We as a species are playing a game of Russian roulette. We truly do not know when, but we know what is coming.

Everyone breathes a sigh of relief when it is explained that disastrous impacts only occur an average of once every several million years. The key fact never discussed is impacts are random. An impact could occur tomorrow, and again the next day, and it would just be a blip on a curved line representing the immensity of geologic time. No one would be left to exclaim, “WOW! What were the odds of that happening?” In the same way the threat of engineered pathogens is ignored, overlooked, or scoffed at in the hopes it will just go away. Just as there is little than can be done to stop seasonal flu, there is very little that could be done to stop such an airborne plague once it begins. Naturally evolved pathogens always leave a certain percentage of survivors but an engineered virus does not follow that rule. We are led to believe there is no defense, but we are being decieved and there is nothing further from the truth.

The Fermi Paradox and Silent Planets

In a recent comment John Hunt mentioned the most probable solution to the Fermi Paradox and as more and more planets are discovered this solution becomes ever more troubling.

Whether civilizations are rare due to comet and asteroid impacts- as Ed Lu recently stated was a possibility- or they self-destruct due to technology, the greater danger is found in human complacency and greed. We have the ability right now, perhaps as hundreds or even thousands of other civilizations had, to defend ourselves from the external and internal threats to our survival. Somewhat like salmon swimming upstream, it may not be life itself that is rare- it may be intelligent life that survives for any length of time that is almost non-existent.

The answer is in space. The resources necessary to leave Earth and establish off world colonies are available- but there is no cheap. Space travel is inherently expensive. Yet we spend billions on geopolitical power games threatening other human beings with supersonic fighters and robot missile assassins. The technology to defend civilization as a whole from the plausible threat represented by this “Great Silence” will cost us no more than what we spend on expensive projects like vertical take-off stealth fighters and hyper-velocity naval rail guns. But it is not the easy money of weapons; it is the hard money of vehicles and systems that must work far from Earth that is unattractive to the corporate profit motive.

Atomic spaceships capable of transporting colonists and intercepting impact threats are the prerequisites to safeguarding our species.

Ivanpah as the future

Cover the deserts in solar energy plants and use electric trains for our transportation infrastructure; the best future I can imagine. A favorite Einstein quote is “Not everything that can be counted counts, and not everything that counts can be counted.” Perhaps the number we are counting that counts is the amount of energy it would require for a future population of 10 billion people to live like we do in the west.

I was surprised to find a statement to the effect that only one method of generating this energy is practical; solar energy beamed to Earth from the Moon; from wiki–

One more step has been taken toward making whole body cryopreservation a practical reality. An understanding of the properties of water allows the temperature of the human body to be lowered without damaging cell structures.

Just as the microchip revolution was unforeseen the societal effects of suspending death have been overlooked completely.

The first successful procedure to freeze a human being and then revive that person without damage at a later date will be the most important single event in human history. When that person is revived he or she will awaken to a completely different world.

Boom and Bust for Wind Energy

Posted by in categories: business, economics, engineering, ethics, events, finance, futurism, human trajectories, policy, sustainability, transparency

Just as the tax incentives that expired after the Carter Administration destroyed a whole new industry, and just as bio fuels recently turned into the bio bomb, wind energy is poised to crash.

We just will not stop destroying our future.

A coal fired power plant runs for years with very little maintenance, without being shut down or started up- the boilers make steam and turn the turbines and we cannot see the stars because we might as well burn those city lights all night long. It is impossible to compete with black rock you dig out of the ground and put on a train and turn into dependable cheap electricity.

Hellalujah, the cannibal apocalypse is coming!

Posted by in categories: asteroid/comet impacts, biological, biotech/medical, counterterrorism, defense, events, existential risks, military, policy, sustainability, transparency

A couple months ago I was in the Seattle public library and overheard a pierced, tatooed, and quite smelly young man telling someone he was waiting for this F-d up civilization to collapse and hoping it would happen soon. The two most likely causes of such a collapse would be an asteroid or comet impact that would throw debris into the atmosphere and stop food production for several years, or a plague. A big impact or an engineered pathogen would be the extreme in this scenario and would not simply take us back to the stone age- it would render the human race extinct.

All the disenchanted Americans who look forward to surviving the collapse of the present world order might want to consider the less fortunate areas of this planet where there is no such rule of law or any agricultural or industrial infrastructure. North Korea has gone through the classic collapse cycle during recent bad winters and the government had to repeatedly deal with widespread cannibalism. It is one of those most perfect warnings where nothing could be more crystal clear to a race of intelligent and technologically advanced beings. And we ignore it.

Turn the sunlight off for a couple years in a row and everything we know would end because everything we eat would end. Think about it the next time you watch an episode of the Walking Dead or watch a movie like The Road. Not world war Z; world war C.

The Electric Septic Spintronic Artilect

AI scientist Hugo de Garis has prophesied the next great historical conflict will be between those who would build gods and those who would stop them.

It seems to be happening before our eyes as the incredible pace of scientific discovery leaves our imaginations behind.

We need only flush the toilet to power the artificial mega mind coming into existence within the next few decades. I am actually not intentionally trying to write anything bizarre- it is just this strange planet we are living on.

Water and Bombs again

Posted by in categories: asteroid/comet impacts, business, counterterrorism, defense, education, engineering, ethics, events, existential risks, futurism, geopolitics, habitats, human trajectories, lifeboat, media & arts, military, nuclear weapons, physics, policy, space, sustainability, transparency

This essay was posted previously last year and removed and has appeared in abridged form in the European Space Safety online Magazine and can also be found on Yahoo voices.

Several dates are cited as marking the beginning of the space age. Sputnik, October 4th, 1957, Yuri’s day April 12th, 1961, and the first successful V-2 launch by the Nazis on October 3rd, 1942, to name a few. Some prefer December 21st, 1968, when human beings first escaped the Earth’s gravitational field on Apollo 8. When studying the events that allowed man to leave Earth, future historians may agree on a date not generally associated with space flight. July 16th, 1945 was Trinity, the first nuclear weapon test. Stanislaw Ulam, a 36-year-old Polish mathematician who helped build “the gadget”, visited ground zero after the test. Ulam later conceived the idea of propelling a spaceship with atomic bombs. Near the end of his life the eccentric genius stated the idea was his greatest work.

When considering nuclear propulsion, it must be understood that space is not an ocean, though often characterized as one. The distances and conditions are not comparable. While chemical energy has allowed humankind to travel across and above the surface of Earth, the energy required to travel in space is of a different order. Water, in the form of steam, was the agent of change that brought about the industrial revolution. Fossil fuel, burned and transformed by steam into mechanical work, would radically change the world in the span of a century. What is difficult for moderns to understand is not only how limited human capabilities were before steam, but how limited they are in the present in terms of space travel. The psychological limits of human beings limit space journeys to a few years. Chemical propulsion is not capable of taking human beings to the outer solar system and back within those crew limits. The solution is a reaction one million times more powerful. Nuclear energy is to the space age as steam was to the industrial age.

A Resilient Logic for Hazardous Times

Posted by in categories: complex systems, economics, engineering, ethics, existential risks, nuclear weapons, policy, sustainability
“If the rate of change on the outside
exceeds the rate of change on the inside, the end is near”
- Jack Welch

Complex societies are heavily addicted to expensive, vulnerable and potentially hazardous infrastructure. We rely on a healthy environment for production of food and access to clean water. We depend on technological infrastructure for energy supplies and communications. We are deeply addicted to economic growth to support growing populations and consumption. If one of these pillars of modern society crumbles our existence will collapse like a house of cards.

The interdependencies and complexities of the system we call modern society has become so intertangled that finding a robust and simple solution to our problems has become close to impossible. Historically the cold war gave us the logic of a “balance of terror”. This logic, originally concerned with a balance of U.S. vs. Soviet military capacities, has lead to an increasingly expensive way of reducing risk and ever expanding bureaucracies to keep us “virtually safe”.

With the onset of a global economic recession, drastic climate change, deadly natural disasters, raging civil wars and diminishing natural resources we need a new logic. A set of moral laws for reducing risk and mitigating consequences applicable at a low cost from the bottom up of entire societies.

The concept of resilience is based on the idea that disasters are inevitable and a natural part of existence. Our best defense is preparedness and engineering systems that not only can withstand heavy strains but also absorb damage. The Institute for Resilient Infrastructure at the University of Leeds gives this definition of “Resilience”;

Per Aspera Ad Astra

Posted by in categories: economics, education, engineering, ethics, futurism, human trajectories, philosophy, policy, rants, scientific freedom, space, sustainability, transparency

The unknown troubles and attracts us. We long to discover a reason for our existence. We look out to the stars through the darkness of space to observe phenomena incredibly far distances away. Many of us are curious about the things we see, these unknowns.

Yet, many of us look skyward and are uninspired, believing that our time and resources best be kept grounded. Despite our human-centered ideologies, our self-assured prophecies, our religious and philosophical beliefs, no existential rationale seems apparent.

We as people welcome technology into our lives and use it constantly to communicate and function. Scientific discoveries pique the interest of every citizen in every country, and technological revolutions have always preceded social and political revolutions from the creation of the internet back to man’s first use of simple tools. Leaders of nations proclaim the importance of science and discovery to our welfare to be utmost.

But what we have seen done recently contradicts these proclamations: space programs are closed; science funding for schools always falls short; and we see no emphasis of the significance of science in our modern culture. Our governments call for the best but provide capital for only the satisfactory, if even. We no longer succumb to the allure of learning simply for the sake of knowing what we once did not know. We have stopped dreaming.
