How to condense water out of air using only sunlight for energy
Posted by Sean Brazell in categories: energy, sustainability
MIT scientists have invented a water harvester that uses only sunlight to pull water out of the air under desert conditions, using a “metal-organic framework” (MOF) powdered material developed at the University of California, Berkeley (UC Berkeley).

Carnegie Mellon University AI beats top Chinese poker players
Posted by Sean Brazell in category: robotics/AI
Artificial intelligence (AI) triumphed over human poker players again (see “Carnegie Mellon AI beats top poker pros — a first “), as a computer sprogram developed by Carnegie Mellon University (CMU) researchers beat six Chinese players by a total of $792,327 in virtual chips during a five-day, 36,000-hand exhibition that ended today (April 10, 2017) in Hainan, China.
The AI software program, called Lengpudashi (“cold poker master”) is a version of Libratus, the CMU AI that beat four top poker professionals during a 20-day, 120,000-hand Heads-Up No-Limit Texas Hold’em competition in January in Pittsburgh, Pennsylvania.

The two fundamental prerequisites for large-scale economic use of space resources are:
1. in-space manufacture of propellants from nonterrestrial bodies, and 2. in-space manufacture of heat shields for low-cost capture of materials into Earth orbit.
The former has been the subject of recent NIAC investigations. The latter would expand by a factor of 30 to 100 time the number of asteroids from which resources could be returned cost-effectively to Earth orbit. With vastly larger populations from which to choose, return opportunities will be much more frequent and targets can be selected where operations would be highly productive, not merely sufficient. The feedstocks for manufacture of life-support materials and propellants are found on C-type near-Earth asteroids, which have high concentrations of hydrogen, carbon, nitrogen, oxygen and sulfur. The total abundance of readily extractable (HCNOS) volatiles in the CI chondritic meteorite parent bodies (C asteroids) is roughly 40% of the total meteorite mass. Further, the residue from extraction of volatiles includes a mix of metallic iron (10% of total mass), iron oxide and iron sulphides (20% as Fe) plus 1% Ni and ~0.1% Co.

We May Be Able to Build a Rocket That Can Go 99.999% the Speed of Light
Posted by Andreas Matt in categories: mathematics, physics, space travel
Theoretical physics often lifts the sanctions we set on our own imaginations. Whether it’s exploring the possibility of warp drives or understanding the rate of the universe’s expansion, we are quick to explore the unknown on our chalkboards until our tech is ready for our ideas.
In a similar deep-dive into the theoretical, a Norwegian professor argues in the journal Acta Astronautica for the of possibility of photon rockets that can reach 99.999 percent of the speed of light (300,000 km/s [186,000 mph]); asserting that, while humanity can’t do it anytime soon, we could potentially build a spacecraft that falls just short of the ultimate speed limit sometime in the future when the necessary technology is feasible.

Entrance to Mars: How this fascinating Dome-Space-Elevator grows in all directions
Posted by Klaus Baldauf in categories: engineering, environmental, space, sustainability
Architecture has evolved and has become much more than just a design realized in concrete and modern building material. It has been transformed to help humanity in achieving all kinds of sustainability.
The eVolo Magazine for Architecture has been organizing another round of Skyscraper Competition in 2017 to honor those visionaries that try to realize a future that benefits humanity and the one Earth we all need to cherish and sustain.
A team from Spain with aspiring architects Arturo Emilio Garrido Ontiveros, Andrés Pastrana Bonillo, Judit Pinach Martí and Alex Tintea is thinking of a hybrid solution, that ensures Humanity’s survival in the early days of Mars’ colonization. The skyscraper design is both clever and beautiful, combining existing technologies with many practical ideas to open up and terraform more red soil as we understand the planet. It’s a genesis of Mars and a revival of form following function.
Ice-nine is a fictitious alternative structure of water that is solid at room temperature. When a crystal of ice-nine contacts liquid water, it becomes a seed crystal that makes the molecules of liquid water arrange themselves into the solid form, ice-nine. Felix Hoenikker’s reason to create this substance was to aid in the military’s plight of wading through mud and swamp areas while fighting. That is, if ice-nine could reduce the wetness of the areas to a solid form, soldiers could easily maneuver across without becoming entrapped or slowed.

Jim Rickards uses ICE 9 in his latest work “The Road to Ruin” to warn investors of a potential ICE 9 event in which the financial system literally freezes up in a domino type event as he describes in a recent interview:

A new CRISPR breakthrough could lead to simpler, cheaper disease diagnosis
Posted by Simon Waslander in categories: biotech/medical, genetics
The controversial laboratory tool known as CRISPR may have found a whole new world to conquer. Already the favored method of editing genes, CRISPR could soon become a low-cost diagnostic tool that could be used practically anywhere to determine if someone has an infectious disease such as Zika or dengue.
The controversial gene-editing tool may be able to identify infections reliably for pennies in places without electricity.
