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!

100YSS A Success

Posted by in categories: education, events, fun, human trajectories, physics, scientific freedom, space

I am very pleased to say that the 2013 100YSS conference held in Houston, TX, was a success. I met a lot of like minded people — people who want to make interstellar travel a reality — though we differ in our opinions of when.

I was especially pleased to be able to visit with Mae Jemison, Jill Tarter and Pamela Contag. These three are amazing, shepherding us along. Shepherding us? Yes, are a loose collection of visionaries going every which way.

There is this wonderful German-language Report on the Higgs Boson and the LHC

Posted by in categories: existential risks, physics

http://www.ardmediathek.de/wdr-fernsehen/quarks-und-co/quark…d=17482362

I learned from it about the unfathomable degree of social coherence among the many thousand scientists and engineers whose synergy makes this largest constructive effort of humankind since the pyramids possible. And it also revealed the wonderful spirit of Peter Higgs who is a loving mind in the old sense of a devout scientist.

Ranga Yogeshwar here made it clear to me for the first time WHY this brave community could not respond to a novelty that would have destroyed their cohesion. The effort was too big to be disturbed even for a few days of “second thoughts.” For that it was too late from the beginning.

So CERN’s public refusal to update its “safety report” for more than 5 years is part and parcel of the beauty of the new pyramid (the word means “immortality”). Imagine the pyramids’ construction having been disturbed by a news that interfered with its political and divine purpose: This would have meant the end of the whole effort and the civilization behind it.

Quantum Metamaterial and the Feasibility of Invisiblity Cloaks

Posted by in categories: engineering, futurism, humor, military, transparency

Meta-materials — materials that have been engineered to have properties that absolutely do not exist in nature — such as negative refraction — are unraveling interesting possibilities in future engineering. The discovery of negative refraction has led to the creation of invisibility cloaks, for example, which seamlessly bend light and other electromagnetic radiation around an object, though such are normally restricted to cumbersome laboratory experiments with split-ring resonators and/or restricted to an insufficient slice of spectrum.

A recent article in ExtremeTech drew attention to the world’s first quantum meta-material, created recently by a team of German material scientists at the Karlsruhe Institute of Technology. It is believed such quantum meta-material can overcome the main problem with traditional meta-materials based on split-ring resonators, which can only be tuned to a small range of frequencies and not conducive to operate across a useful slice of spectrum. While fanciful applications such as quantum birefringence and super-radiant phase transitions are cited it is perhaps invisibility cloaks that until very recently seemed a forte of science fiction.

From Fiction - The Invisible Man

Breakthroughs at the National Tsing-Hua University in Taiwan have also made great strides in building quantum invisibility cloaks, and as the arXiv blog on TechnologyReview recently commented ‘invisibility cloaks are all the rage these days’. With such breakthroughs, these technologies may soon find mass take-up in future consumer products & security, and also have abundant military uses — where it may find the financial stimulus to advance the technology to its true capabilities. Indeed researchers in China have been looking into how to mass-produce invisibility cloaks from materials such as Teflon. We’ll all be invisible soon.

A Reminder to every Citizen of a Planet including its Space Station

Posted by in categories: existential risks, particle physics

Science is based on dialog. Not a single colleague including Hawking and his crew contradicts my safety-relevant finding for 5 years. This fact can only have one of two reasons:
(1) The finding is so embarrassingly stupid that to take it up would suffice to soil the respondent.
(2) The finding harks back so deeply to the young Einstein that it causes fear to tread upon.

One country – my own – singlehandedly left CERN in response (only to surreptitiously return under non-publicized pressure).

Obviously the offered result (“gothic-R theorem”) has historical dimensions. Everyone’s survival is affected by it probability-wise if it is valid. We “live in an interesting time” as the Chinese proverb goes.

800 newspapers reported on the theorem in 2008. Only Aljazeera remained four years later. There is a “curfew of silence” obeyed by my colleagues. Not a single counterargument is in the literature against my result published in 2008 and its many sequels.

Ruling the Rhetoric on North Korea: A Pedagogical Perspective

Posted by in categories: business, education, ethics, geopolitics, military, policy

As the Western media and governments continue poking fun and demonizing a very misunderstood country, there are a group of people who are taking it upon themselves in ignoring the propaganda and instead reaching out with compassion and understanding. These people are visiting and working in North Korea. They’re not North Koreans, but the love and connection they’ve gained with the North Korean people is real and deserve to have their stories told.

I’ve interviewed a few people of importance in gaining greater insight into the country, its people, its military, and its government. It is my goal in providing an open venue for them to speak out and hopefully gain enough attention for others to follow suit.

Here I’ve interviewed Michael Bassett and Felix Abt. Mr. Bassett is a decorated Army Veteran who holds a BA in International Communication from the American University in Washington DC, a graduate certificate in North Korean Affairs from Yonsei University’s Graduate School of International Studies in Seoul, South Korea, and is currently working on his MA in Public Diplomacy from the American University.

H+ Poetry: A Cosmist’s Tale

Posted by in categories: life extension, media & arts, philosophy

This poem had originally appeared on Transhumanity.

Opt Not for Death

A cosmist’s cosmological comet is in correlation
with the connotational confrontation of dreams,
Dreams that are only dreamt by the dreary of death,
Death only dreamt when no dreams are left.
For what is left than the dichotomy of life and naught,
foretold by the whispers of our ancestors’ ancestors? (more…)
