Sebastopol California to get a 1Gbps Internet connection at 70 a month

first_img © 2010 PhysOrg.com Explore further (PhysOrg.com) — The people of Sebastopol, California are in for a treat. Thanks to a collaboration between search giant Google and Sonic.net they will have the honor of being the first residential area in the United States that will have a 1Gbps Internet connection available. This is only the second location to get the benefit of a connection of this speed. The first US trials were done at Stanford University, where 850 faculty and staff homes on campus were enabled with the connection at a speed that would have seemed like a pipe dream even five years ago.

This system includes not only the Internet service but also offers two phone lines with unlimited long distance calling. A slower plan will offer users a 100Mbps connection and one phone line with unlimited long distance calling for a rate of roughly $40 each month. This makes the rates comparable to make services currently in existence in many residential areas of the United States. The deployment will roll out in stages, with 60 homes being hooked up in the next month and the rest connected by the end of the year. If all goes well similar rollouts will be done in other California cities such as Santa Rosa or San Francisco. The next city slated with a definite 1Gbps fiber network to be installed is Kansas City, which sent a proposal as part of its Fiber for Communities Project. Their network is expected to begin operations at some point in 2012. This document is subject to copyright.

Staples customers can get a head and more with 3D printing

first_img(Phys.org)—Given the curiosity and novelty factors, if not utility, of 3-D printers. was it not just a matter of time? A speeded-up trend is in the works of getting 3-D printing into the hands of all consumers, from agency creatives to industrial product designers, to architects, to health professionals, to students, to gift-givers with a sense of flair and humor. 3-D printing is coming to Staples. A partnership between Staples Printing Systems Division and Mcor Technologies has resulted in the launch of a 3-D printing service, “Staples Easy 3D.” Explore further Staples to speed up closure of 15 stores in US This is an online service via the Staples Office Centre where customers will upload their designs as electronic files to Staples’ website, and can then pick up the printed objects at their local office supply store, or can have the objects shipped to their address. Staples will use the Mcor IRIS 3-D printer.The announcement was made on November 29 at EuroMold 2012 in Frankfurt, a gathering of designers, developers, producers, suppliers and end users, who were viewing the latest in industrial 3-D printers and additive manufacturing devices. EuroMold is billed as “the world’s leading fair” for moldmaking and tooling, design and application development.The Staples service will start with stores in the Netherlands and Belgium in early 2013. President Wouter Van Dijk, president of the Staples Printing Systems Division in Europe, said “Customized parts, prototypes, art objects, architectural models, medical models and 3-D maps are items customers need today, in a more affordable and more accessible manner. Mcor will help us to keep prices low, quality high and color brilliant as we meet the demand.”Those outside the two companies recognize the move as one to further seed 3-D printing as a service for the mass market. As bloggers have pointed out, Staples is not the first to offer such services but represents the first move toward making 3-D printing available from a chain retailer. The Mcor IRIS printer is designed for full-color prints and the company promotes its IRIS line as an affordable 3-D result that has very realistic coloring. The company says its Mcor Matrix and IRIS models are the only 3-D printers that can create physical 3-D models from paper (standard Letter/A4 sheets) whether fresh or used. With pages cut and bound together, the model is tough and durable, added Mcor. The models are waterproof, and they are disposable in recycling bins. Mcor started business in 2004 with a team specializing in 3-D printing, software and CAD/CAM. Mcor has offices in Ireland, the UK and America.After Staples Easy 3D makes its debut in the Netherlands and Belgium in the first quarter of 2013, the service will be rolled out to other countries. © 2012 Phys.orgcenter_img More information: Press release Citation: Staples customers can get a head and more with 3-D printing (2012, December 3) retrieved 18 August 2019 from https://phys.org/news/2012-12-staples-customers-d.html This document is subject to copyright.

Students flashlight works by body heat not batteries

first_img Vibration-powered generating batteries recharge when shaken (Phys.org) —Ann Makosinski from Victoria, British Columbia, has an LED flashlight powered by body heat. This inventor has a flashlight that glows when she holds it. The story gets more interesting, though. She is 15 years old and her flashlight has got her into the finalist ranks for the Google Science Fair. Her work is a result of a general interest in alternative energy. She said that she is “really interested in harvesting surplus energy, energy that surrounds but we never really use.” Enter the Hollow Flashlight, which works according to the thermoelectric effect—creating electric voltage out of temperature difference. As a Grade 10 student at St. Michaels University School in Victoria, she was deciding on a topic for a science project when she discovered the Peltier tile, producing electricity when one side of the tile is heated while the other side is cooled. More information: Google Science Fair project Citation: Student’s flashlight works by body heat, not batteries (2013, July 1) retrieved 18 August 2019 from https://phys.org/news/2013-07-student-flashlight-body-batteries.html “Using four Peltier tiles and the temperature difference between the palm of the hand and ambient air, ” she said in her project statement, “I designed a flashlight that provides bright light without batteries or moving parts. My design is ergonomic, thermodynamically efficient, and only needs a five degree temperature difference to work and produce up to 5.4 mW at 5 foot candles of brightness.”She ran some calculations to see if the warmth from a human hand could generate enough energy via a tile to power a flashlight. She presented her hypothesis:” If I can capture enough heat from a human hand and convert it efficiently to electricity, then I can power a flashlight without any batteries or kinetic energy.” She presented her objective: “To make a flashlight that runs on the heat of the human hand.”To begin, she bought Peltier tiles and tested them to see if they could produce sufficient power to light an LED. The power was no problem but getting the needed voltage was, as the tiles did not generate enough of the voltage needed. As she learned, making some changes to the circuit design might turn a page. She used the Internet for information, experimented with different circuits, and got lucky, finding an energy-harvesting article on the Internet that made note of a circuit that could provide enough voltage when used with a recommended transformer. She talked about a point where she realized her battery-free flashlight could behave as she had hoped: “The final design included mounting the Peltiers on a hollow aluminum tube which was inserted in a larger PVC pipe with an opening that allowed ambient air to cool the tube. The palm wrapped around a cutout in the PVC pipe and warmed the tiles. The result was a bright light at 5 degree Celcius [sic] of Peltier differential. The flashlight worked!” In conclusion, she said, she succeeded in powering a flashlight using only the heat of the hand. Out of two flashlights that she made, neither which needed batteries, they worked. Materials for the flashlight project cost her $26. Considering that the effort has qualified her as a finalist in the Google Science Fair, where 15 finalists from around the world are competing for the prizes, that is not an unwise investment. The top winner gets a $50,000 scholarship and trip to the Galapagos Islands. The prize ceremony takes place in September. Winners will be chosen in different age categories—13-14, 15-16, 17-18. © 2013 Phys.org Explore further This document is subject to copyright.

Astronomers investigate starforming processes in the young stellar object G29862–0044

first_img Giant molecular outflow detected from the quasar PDS 456 © 2019 Science X Network More information: M. B. Areal. Studying star-forming processes towards G29.862-0.044. arXiv:1904.10914 [astro-ph.GA]. arxiv.org/abs/1904.10914 Explore further Citation: Astronomers investigate star-forming processes in the young stellar object G29.862–0.044 (2019, May 6) retrieved 18 August 2019 from https://phys.org/news/2019-05-astronomers-star-forming-young-stellar-g298620044.html Astronomers have conducted a multiwavelength study of a young stellar object (YSO) known as G29.862–0.044, which provides more hints into star-forming processes. Results of the study, presented in a paper published April 24 on arXiv.org, could be important for improving our general knowledge about how stars form and evolve. YSOs are stars in early stage of evolution, in particular protostars and pre-main sequence stars. They are usually observed embedded in dense molecular clumps, environments containing plenty of molecular gas and interstellar dust.Located some 21,000 light years away from the Earth, G29.862–0.044 (or G29 for short) is embedded in the massive star-forming region G29.96–0.02. This YSO was a target of multiwavelength observations performed by a team of astronomers led by María Belén Areal of University of Buenos Aires, Argentina. They used the 15-m James Clerk Maxwell Telescope and Gemini-North 8.2-m telescope to study G29 and its environment in order to obtain a complete picture of this YSO, the related star-forming processes, and the interstellar medium around it.”In the present work, we focus on the study of the southern massive YSO cataloged as the Red MSX source G029.862–0.044 (hereafter G29). (…) The surrounding interstellar medium of G29 is studied using molecular lines data. (…) The physical conditions of G29 molecular outflows and the clump where the YSO is embedded are characterized,” the astronomers wrote in the paper.The observations allowed the astronomers to detect molecular outflow in G29, what is typical for YSOs at the earliest stages of formation. In particular, they found a red molecular outflow, but they were not able to distinguish any blue molecular outflows. This is most likely due to the presence of a dense concentration of cold dust southwards of this YSO as such feature could hide the blue outflows.The researchers also estimated physical parameters of the red molecular outflow, obtaining a mass of around 82 solar masses and an energy of approximately 20 quattuordecillion erg. According to the paper, these values are characteristic for molecular outflows.Moreover, the scientists characterized the molecular cloud in which G29 is embedded in, unveiling its morphology and calculating its mass. They estimate that mass of the cloud is at a level of some 10,000 solar masses.Furthermore, studying G29’s surroundings, the team found that the emission in the Ks-band towards this YSO showcases a cone-like feature pointing to the northwest in direction to the red molecular outflow. This feature was observed to have two arc-like structures, similar to what was found in massive YSOs with precessing jets.The authors of the paper concluded that the detected near-infrared emission at the Ks-band towards G29 most likely arises from a cavity cleared in the circumstellar material by the action of a jet. They added that this emission may be in fact due to a combination of various emitting processes.”Further investigation is needed in order to determine such processes. We are currently analyzing in detail the near-IR data set (the JHKs broadbands and specially the emission lines observed with the narrow-bands), which will provide valuable information about the origin and physical processes taking place in this intriguing structure,” the researchers wrote.
