From a paper at physics world, a nanoscale perfect lens could reverse the Casimir force note: perfect lens have not been created yet, so it will take some years to make this happen. Metamaterials could lead to frictionless micro and nanoscale machines. Metamaterials (which exist) lead to perfect lens (research is progressing towards this goal). …
Michael Anissimov has an interesting article AI and Effective Sagacity, by Mitchell Howe I believe that a large part of the surprisingly common discord between IQscores and societal significance can be explained by my simple theory of‘Effective Sagacity’ The amount previously invested and currently spent in highest-levelthought combine to form one’s “Effective Sagacity.” In the …
Dwave has published a paper which claims that the effect of strong decoherence on AQC is to (generically) square the time it takes an optimal algorithm to operate. This wipes out quadratic speed-ups (like adiabatic Grover search), but implies that exponential gains remain exponential for AQC even with total loss of phase coherence. The paper …
Investors from California to Singapore are making a big bet that China will have to appreciate the yuan Rajeev De Mello, who helps manage $600 billion as head of Western Asset’s Singapore office, says the currency may climb 6.4 percent this year to 7.11 to the dollar as the government attempts to restrain the world’s …
A 182 page pdf from Australia that befores a detailed analysis on the CO2 generated for the full life cycle of different energy sources and compares energy sources based on energy intensity Here is the chart that summarizes the comparisons. Notice the ranges in the brackets. Those are the range across which the values could …
Researchers have imaged the quantum order which is sometimes referred to as phase coherence and can manipulate the distance over which it can be maintained. The team from the London Center for Nanotechnology, has detected a hidden magnetic “quantum order” that extends over chains of 100 atoms in a ceramic without classical magnetism. Image of …

Many people think that nuclear power is not being added in the USA or that it cannot be added in time to help with climate and pollution problems. That belief is not correct. The world has 320 nuclear reactors in the construction pipeline This is an increase of 80 reactors from January 2007 when 240 …
Carnival of Space week 13 is up at the liftport blog My submission was the improvement/variant of a hypersonic skyhook Colony Worlds discusses a skyhook for Mars that would reach down to within 11 kilometers of the surface He refers to it as an orbital space elevator. Mars orbiting space elevator reaching out from Phobos …
The site for the people making the nanomechanical computer indicates there are other work They are also working on artificial ion channels: We apply nanostructuring techniques to the most fundamental unit of information exchange in living systems: ion channels. Ion channels regulate the flow of ions through cell membranes, thus maintaining electrostatic activity and potential …
The liberty ship is a Gaseous Core Nuclear Reactor design, of the Nuclear Lightbulb subvariant. This design is from nuclearspace.com It has an ISP of 3,060 and leverages existing technology to conservatively deliver 1000 tons to low earth orbit, 33% of its takeoff weight. It flies to space with a thousand tons of cargo, and …
