Havens over Hell — Ecosystems of the Venusian Tropopause

Posted by in categories: climatology, engineering, futurism, habitats, space

In our on-going ambitions to colonise space — and our search for exo-planets in goldilocks zones, it is often overlooked that the most Earth-like area known to us is in our own Solar System, and very nearby — the upper reaches of the Venusian troposphere.

Whilst the surface of Venus invokes classical images of Hell — a dark sea of fire and brimstone, where temperatures raise to an incredible 450°C — hot enough to melt lead, tin and zinc, and pressurised to such an extent (92 bar) that in these conditions the atmosphere ghosts in and out of an ocean of supercritical carbon dioxide — sulphur dioxide tints the air, and sulphuric acid rains down on volcanic plains. One just needs to look to the skies…

At about 50 km to 60 km above the surface, the upper reaches of the Venusian troposphere, the environment is quite different. At these high altitudes the temperature is in our comfort zone of 0°C to 50°C, and the air pressure similar as habitable regions of Earth.
Havens over Hell - Ecosystems of the Venetian Tropopause

An atmosphere rich in carbon dioxide (96.5%) and abundant solar radiation, the conditions are ideal for photosynthesis. One could imagine solar energy powered crafts could easily sustain ecosystems where the ideal conditions for photosynthesis ensure an abundant source of food and oxygen for inhabitants. The solar energy here is abundant and in all directions — the high reflectivity of clouds below causes the amount of light reflected upward to be nearly the same as that coming in from above, with an upward solar intensity of 90% — so aircraft would not need to concern about electricity or energy consumption. Indeed, that energy would not even be needed to keep the craft airborne — as the oxygen store would also double up as a natural lifting agent for such aircrafts, as in the Venusian atmosphere of carbon dioxide, oxygen is a lifting gas — in the same way helium is a lifting gas on Earth. With temperature, pressure, gravity, and a constant source of food and oxygen via plant growth all accounted for, not to mention close proximity to Earth, waste & water recycling would be the main challenge for the permanence of such Venusian aircraft — where the initial establishment of a balanced ecosystem is key. The engineering challenge would be far less than that of establishing a colony or base on Mars. Just don’t look down!

There will always be a Moon over Tokyo: Fukushima

Posted by in categories: climatology, engineering, ethics, nuclear energy, sustainability

News this past week on Fukushima has not been exactly reassuring has it. Meanwhile the pro-Nuclear lobby keep counting bananas. Here I’ve gathered together some of the recent news articles on the unfolding crisis. Interested to hear some comments on this one.

We are as Gods and have to get Good at it [video]

Posted by in categories: climatology, complex systems, engineering, ethics, existential risks, futurism, geopolitics, homo sapiens, human trajectories, philosophy, sustainability

The shift that has happened in 40 years which mainly has to do with climate change. Forty years ago, I could say in the Whole Earth Catalog, “we are as gods, we might as well get good at it”. Photographs of earth from space had that god-like perspective.

What I’m saying now is we are as gods and have to get good at it. Necessity comes from climate change, potentially disastrous for civilization. The planet will be okay, life will be okay. We will lose vast quantities of species, probably lose the rain forests if the climate keeps heating up. So it’s a global issue, a global phenomenon. It doesn’t happen in just one area. The planetary perspective now is not just aesthetic. It’s not just perspective. It’s actually a world-sized problem that will take world sized solutions that involves forms of governance we don’t have yet. It involves technologies we are just glimpsing. It involves what ecologists call ecosystem engineering. Beavers do it, earthworms do it. They don’t usually do it at a planetary scale. We have to do it at a planetary scale. A lot of sentiments and aesthetics of the environmental movement stand in the way of that.

“The more anxiety one produces, the more the discussion there would be about how real and how possible actual existential threats are.”

John Hunt recently queried me on what steps I might take to form an organization to advocate for survival colonies and planetary defense. His comment on anxiety is quite succinct. In truth the landing on the moon was the product of fear- of the former Soviet Union’s lead in rocket technology. As we as a nation quelled that anxiety the budget for human space flight dwindled. But the fear of a nuclear winter continued to grow along with the size of our arsenals.

Interestingly, at the height of the cold war, evidence of yet another threat to human existence was uncovered in the Yucatan peninsula of Mexico in 1981; Chicxulub. But even before the dinosaur killer was discovered, perhaps the greatest threat of all to humanity was born in 1973 when Herb Boyer and Stanley Cohen created the first genetically modified organism. The money to answer both of these threats by going into space continues to be expended by the military industrial complex.

Mile wide rocks in space and microscopic organisms on earth are both threats to our existence, but the third and undoubtedly greatest threat is our own apathy. Why do we expend the tremendous resources of our race on everything BUT keeping it from going extinct?

The Truth about Space Travel is Stranger than Fiction

I have been corresponding with John Hunt and have decided that perhaps it is time to start moving toward forming a group that can accomplish something.

The recent death of Neil Armstrong has people thinking about space. The explosion of a meteor over Britain and the curiosity rover on Mars are also in the news. But there is really nothing new under the sun. There is nothing that will hold people’s attention for very long outside of their own immediate comfort and basic needs. Money is the central idea of our civilization and everything else is soon forgotten. But this idea of money as the center of all activity is a death sentence. Human beings die and species eventually become extinct just as worlds and suns also are destroyed or burn out. Each of us is in the position of a circus freak on death row. Bizarre, self centered, doomed; a cosmic joke. Of all the creatures on this planet, we are the freaks the other creatures would come to mock- if they were like us. If they were supposedly intelligent like us. But are we actually the intelligent ones? The argument can be made that we lack a necessary characteristic to be considered truly intelligent life forms.

Truly intelligent creatures would be struggling with three problems if they found themselves in our situation as human beings on Earth in the first decades of this 21st century;

1. Mortality. With technology possible to delay death and eventually reverse the aging process, intelligent beings would be directing the balance of planetary resources towards conquering “natural” death.

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.
