Medium orbit satellites for the faster backbone communication for telecom and ISP as the basis for cheaper and faster broadband

Standard Geosynchronous (GEO) satellites operate approximately 36,000km away from Earth. As a result, round-trip data transmission times significantly exceed 500 milliseconds. O3b’s Medium Earth Orbit (MEO) satellites are far closer – approximately 8,000km away from Earth. As a result, round-trip data transmission times are reduced to approximately 130 milliseconds. They will be fully operational by …

Error in population observations and population forecast errors

When compared with ex-post observed real trends, the twelve sets of populations projections that the United Nations prepared between the 1950s and the end of the 1980s show a clear tendency over time towards better accuracy. Part of this improvement is due to better data for base populations. The number of elderly persons for the …

Carnival of Nuclear Energy 162

The Carnival of Nuclear Energy 162 is up at Atomic Power Review Atomic Insight discusses the energy documentary Pandoras Promise. The film shows people and allows them to speak for themselves. It does not limit the footage of nuclear energy opponents to classic reels of ’70s or ’80s vintage “No Nukes” concerts, but also shows …

China’s power needs will nearly triple to 15000 TWh by 2030 and most of it will still be coal power

“It is very unlikely that demand for thermal coal in China will peak before 2030,” said William Durbin, the Beijing-based president of global markets with Wood Mackenzie, an energy research and consulting firm, in a statement accompanying the release of a new report entitled “China: The Illusion of Peak Coal.” “Despite efforts to limit coal …

Transformer toys made that can actually transform themselves

Tomy has exhibited the prototype of a new hobby robot “International Tokyo Toy Show 2013” that is a self-transforming robot. Currently, the Transformer robot is unable to walk, but as you’ll see in the following video it is already able to transform from a car into its humanoid shape on its own. The mini servos …

How many African countries want Google Loon – the balloon internet system

Google’s latest pet project, called Loon, is meant to deliver the Internet to new parts of the world via solar-powered balloons soaring through the stratosphere. Yet some technologists in Africa say the project may be unrealistic as a competitive networking solution for their continent. The Google Loon service would (initially) only provide 3G connectivity, meaning …

Comparing centenarians to extremely sick diabetic people has found more genes that cause diabetes

Aging researcher compared centenarians on one side and T2D patients with severe complications (people with extreme diabetic complications) on the other, thus maximizing possible genetic differences among patients and controls. Their data suggest that the use of relatively small numbers of cases and controls with extreme phenotypes (thus reducing sample heterogeneity) in genetic association studies …

Focardi who worked with Rossi on the Energy Catalyzer has died

Rossi has announced that Prof. Sergio Focardi has died. Sergio Focardi worked with Rossi to develop the highly controversial energy catalyzer (cold fusion / LENR – low energy nuclear reaction) device. Sergio Focardi (1932–2013) was an Italian physicist and professor emeritus at the University of Bologna. He led the Department of Bologna of the (Italian) …

Nanoscale etching of 3d fractal structures with many applications including 3d fractal antennas and structures for filters

Journal of Micromechanics and Microengineering – Fabrication of 3D fractal structures using nanoscale anisotropic etching of single crystalline silicon When it comes to high-performance filtration, separation, sunlight collection, surface charge storage or catalysis, the effective surface area is what counts. Highly regular fractal structures seem to be the perfect candidates, but manufacturing can be quite …

Graphene oxide have a one molecular monolayer transistor chips and a step toward molecular electronics

Graphene oxide films have been used to make a transistor composed of just one molecular monolayer functioned on a chip. The first applications for the graphene-based chip will be in testing future molecular electronics, the chip itself represents a first step towards integrated molecular circuits. “The difference between this work and “graphene transistors” in general …
