Terahertz near field nanoscope has 40 nanometer resolution. Nanoscale resolution is achieved by THz field confinement at the very tip apex to within 30 nm, which is in good agreement with full electro-dynamic calculations. Imaging semiconductor transistors, we provide first evidence of 40 nm (λ/3000) spatial resolution at 2.54 THz (wavelength λ = 118 μm) …
Carnival of Space Week 74 is up at Kentucky Space. This site contributed an article about the Hyperion uranium hydride nuclear power reactor and how its light weight would make it suitable for power lunar facilities. Centauri Dreams talks about laser pushed solar sails. The lasers powered by using tethers in Jupiter’s magnetosphere for the …
1. Mirrored drones can make jet mounted lasers more effective. [H/T alfin and Tom Craver] The flying laser cannon could be accompanied by a fleet of unmanned aerial vehicles (UAVs) fitted with mirrors. These relay UAVs would be harder to spot and more disposable than a 747, and could bounce the high-energy beam onto targets …
Free piston engines could achieve efficiencies of 50% which is almost double a regular gas combustion engine. However, new super efficient diesel engines could be even better, plus diesels would be more familiar to the market place. Some small companies are working on free piston engines and there are researchers around the world at Sandia …
The Hyperion Power Generation uranium hydride reactor will weigh fifteen to 20 tons, depending on whether you’re measuring just the reactor itself or the cask—the container that we ship it in—as well. It was specifically designed to fit on the back of a flatbed truck because most of our customers are not going to have …
An 80-base-pair piece of DNA to be sequenced (shown here in purple) is first inserted into a circular template of DNA, along with four stretches of synthetic DNA, called adaptors (pink and blue). A specialized enzyme then makes hundreds of consecutive copies of the DNA circle. Thanks to chemical properties engineered into the adaptor sequences, …
Vertical farming/urban farming is a plan to grow produce in vertical, multi-story structures within urban areas to reduce the dependence on food grown and transported long distances. Vertical farming will be using new versions of hydroponics and aquaponics. It will use about 100 times less water and provide over 5 times greater energy efficiency. The …
ASML Holding NV (ASML) presents today at the 2008 International Symposium on Extreme Ultraviolet Lithography (EUV) on recent achievements in its EUV lithography program and unveils a production system roadmap that supports cost-effective chip manufacturing to at least 11 nanometers (nm). This would enable the ITRS roadmap to stay on track through 2022. The ASML …
Spacex Exploration Technologies has successfully launched the first privately-developed all-liquid fuel rocket that was able to reach orbit. Falcon 1, a 70-foot-long rocket powered by liquid oxygen and kerosene, is the first in a family of low-cost launch vehicles priced at $7.9 million each. Besides the Falcon 1, SpaceX is developing for NASA a larger …
This month the MIT team reports extending its fluid separation theory to three dimensions, as shown by this simulation of a fluid separating (green lines) from the surface of a spinning sphere it is flowing past. Image courtesy / Amit Surana, Gustaaf Jacobs and George Haller, MIT MIT scientists and colleagues have reported new mathematical …
Techrockies has an interview with John Deal, the CEO of Hyperion Power Generation. Below are the highlights with some new information. Hyperion Power generation is trying to make a factory mass produced uranium hydride molten core reactor which will generate 70 MWt and 27-30MWe. Hyperion Power Generation plans to sell and build the first 4000 …
