Sorry Collapsitarians, Doomers and Dystopians a Full Collapse Will Not Happen

Collapsitarians are described the Technium. Former President Reagan defined a recession as when your friend lost his job and a depression as when you lost your job. Collapse is when no one has a job; in fact, there are no longer any such things as jobs to be had. Various types of doomers/collapsitarians/dystopians: * Luddites, …

The Nuclear Orion Home Run Shot, All Fallout Contained

The typical analysis of the nuclear Orion external pulse propulsion rocket is to use constant charges (bombs) every 1.1 seconds to launch with people inside who experience 4Gs or less. Nuclear Orion can achieve launch costs of less than $1/kg and perhaps a tiny fraction of that. This is 1000 to 20,000 times cheaper than …

Nanotechnology and Technology Acceleration Buzz is Higher Because Actual Developments Are Showing Pessimists Were Wrong

J Storrs Hall has another excellent article, this one on validity of the molecular manufacturing vision and the usefulness of futurists in tough economic times. Josh states that the job of a futurist is to turn on the lights, to show what paths could actually lead to prosperity. I would say it is necessary to …

Geoengineering Proposals Analyzed and Compared for Cooling Potential

Researchers at the University of East Anglia (UEA) have carried out the first comprehensive assessment of the relative merits of different geoengineering schemes in terms of the climate cooling potential. Their paper appears in the journal Atmospheric Chemistry and Physics Discussions. [H/T Greencar congress Using a mix of these geoengineering techniques and mitigating production of …

Single Atom Silicon Atomic Quantum Dots at Room Temperature

Single atom quantum dots created by researchers at Canada’s National Institute for Nanotechnology and the University of Alberta make possible a new level of control over individual electrons, a development that suddenly brings quantum dot-based devices within reach. It is demonstrated that the silicon atom dangling bond (DB) state serves as a quantum dot. Coulomb …

Cambridge Making Carbon Nanotubes Ribbons at Centimeter Lengths with 9 Gpa Strength, Which is Four Times Stronger than Kevlar

The Times UK reported claims that Alan Windle’s team at Cambridge University had created the world’s strongest ribbon. I finally tracked down specifics of this work. UPDATE: Details on hypersonic skyhooks/rotovators [orbital ropes] that would be enabled with these materials as well as lunar and Mars space elevators. Background on strength of materials, units of …

Micron Gap Thermal Photovoltaics

MTPV, a startup based in Boston that has raised $10 million, says that it has developed prototype micron-gap thermal photovoltaics that are large enough for practical applications. Thermal photovoltaics use solar cells to convert the light that radiates from a hot surface into electricity. The first applications will be generating electricity from waste heat, eventually …
