We have had frequent coverage of contour crafting aka printing buildings using a big inkjet printer with cement as the ink There is a TEDx talk from a fellow named Behrokh Khoshnevis, who is a professor of engineering at USC, where he directs something called the Center for Rapid Automated Fabrication Technologies. CRAFT has stated …
University of Utah physicists invented a new “spintronic” organic light-emitting diode or OLED that promises to be brighter, cheaper and more environmentally friendly than the kinds of LEDs now used in television and computer displays, lighting, traffic lights and numerous electronic devices. “It’s a completely different technology,” says Z. Valy Vardeny. The Utah physicists made …
In combination with prior observations of a large gap in the spin excitation spectrum, new research indicate an incipient charge-density-wave instability competes with superconductivity. Armed with this knowledge, scientists can start to design new materials that will bring superconductors out of the cold (room temperature superconductors) and into large-scale real world applications. Researchers from the …
Nasaspaceflight talks about Spacex starting up their reusable Faclon 9 rocket development program this year and the advances in the Merlin 1D engine that could fly this year. Upcoming upgrades to the engine (Merlin 1D) will provide a vast improvement in performance, reliability and manufacturability – all of which could provide a timely boost to …
The carnival of nuclear energy 32 is up at Canadian Energy Issues Idaho Samizdat gives out Laurels for developments that exceeded expectations for nuclear energy and Hardlys for disappointments. Two articles from this site: Average nuclear capacity factor by country from 2007 to 2009 and an update on new nuclear construction Japan is reducing the …
Ad Support : Nano Technology Netbook Technology News Computer Software Lawrenceville Plasma Physics fusion project update and details from the June 22 ICOPS conference. J. P. Appruzese and his colleagues at the Naval Research Laboratory noted in their presentation at ICOPS that several experiments with pinching machines had achieved ion energies above 10-20 keV, with the …
Figure caption:(a) Colored scanning electron microscope image of the measured device. Aluminum top gate is used to induce a two-dimensional electron layer at the silicon-silicon oxide interface below the metallization. The barrier gate is partially below the top gate and depletes the electron layer in the vicinity of the phosphorus donors (the red spheres added …
Are Black Hole Starships Possible? (20 page pdf) By Louis Crane and Shawn Westmoreland, Kansas State University (H/T Crowlspace) The purpose of this paper is to investigate whether it is possible to build artificial Black holes of the appropriate size, and to employ them in powerplants and starships. The conclusion we reach is that it …
STAIf 2007- Mach-Lorentz Thruster (MLT)Applications presentation by Paul March. 1-G Space Drive One-G constant acceleration and deceleration space drive would mean Earth-to-moon in 4 hours, Earth to Mars in 2-5 days, Earth to Saturn in 8-9 days. If the Mach Effect is real [mass fluctations) and behaves as theorized (with some experimental confirmation) by James …
