$116 million for broadband targets unserved areas of Vermont

first_imgThe US Department of Agriculture (USDA) announced Wednesday that an $81 million broadband stimulus grant and a $35 million government backed loan to Springfield-based Vermont Telephone Company (VTel).  The $35,166,081 loan and $81,664,754 grant to VTel Wireless, Inc for their Wireless Open World (WOW) project is one of 49 broadband infrastructure projects announced nationally.  The broadband investments will give rural residents in 29 states access to improved service that will expand economic, health care, educational, and many other opportunities to underserved rural communities. Today’s announcement is part of the second round of USDA broadband funding through the American Recovery and Reinvestment Act (Recovery Act).‘The VTell Wireless, Inc. project will give rural Vermont communities access to the tools they need to attract new businesses, jobs, health care and educational opportunities,’ said Molly Lambert, USDA Rural Development State Director.  ‘Bringing broadband to rural areas of the state provides a gateway for businesses and key institutions ‘ such as libraries, schools, public safety and community centers ‘ to provide services to thousands of people. Building the Wireless Open World network will create jobs and the completed system will provide a platform for rural economic growth in Vermont for years to come.’The funding will allow VTel Wireless to design, engineer and construct the network, which will pass more than 57,000 homes and 3,700 businesses and provide jobs for an estimated 1,800 Vermonters.  The company plans to use a model that proved effective in rural America during the Great Depression, called Rural Radio Farm Forum.  They plan to send out teams of Rural Broadband Farm Forum field workers to organize several thousand neighbor-to-neighbor small-group meetings to discuss and show how broadband can help find jobs, improve schools, start businesses, access federal and state assistance, and enhance rural life. VTel President Michel Guite said the federal funds will enable the company to build VTel’s WOW system to nearly all of Vermont’s unserved homes, businesses and anchor institutions; a one gigabit fiber network to VTel’s existing customers; and a community visit program aimed at helping Vermonters identify ways broadband access can improve social and economic opportunities.  VTel is contributing $30 million in equity to the project.  Guite estimates the work will create as many as 1,800 jobs and build a platform that will offer thousands more Vermonters new economic opportunities for years to come.US Senator Patrick Leahy (D-VT) said, ‘VTel and USDA’s Rural Utilities Service (RUS) have partnered to build a game-changing network here in Vermont.  This stimulus grant ranks among the most promising breakthroughs in rural economic development since rural electrification.  This grant will directly impact the lives of Vermonters today ‘ whether they are hanging fiber, designing the network or getting access to broadband for the first time.  This is an investment in Vermont’s economy today that will also help shape Vermont’s economic future. It will give Vermont a critical piece of the infrastructure that we need to prosper.’  Leahy is the most senior member of the Senate Agriculture Committee, which has jurisdiction over USDA and its Rural Utilities Service.US Senator Bernie Sanders (I-VT) said, ‘In the year 2010, every community in Vermont and America should have access to high-quality broadband service.  This very large USDA grant from the stimulus package will not only put Vermont in a position of achieving that goal, it also will create hundreds of new jobs in our state.  While much work remains to be done in sorting out the details and making sure that broadband access reaches and is affordable for all Vermonters, this is an important step toward achieving universal broadband access in our state.’US Representative Peter Welch (D-VT), a member of the House Energy and Commerce Subcommittee on Communications, Technology and the Internet, said, ‘Today’s announcement launches a broadband revolution in Vermont. Together with last month’s broadband grants, this award to VTel will help Vermont leapfrog from one of the least connected states to one of the most.  By building out our state’s communications infrastructure, we will create jobs today.  And by providing broadband access to businesses, community institutions and families, we will lay the groundwork for economic growth for decades to come.’‘Vermont’s success in competing for these valuable funds will help bring broadband and cell phone service to every corner of our state,’ said Governor Jim Douglas.  ‘I applaud VTel for its foresight and commitment to make long-term investments in Vermont.  VTel’s investments in wireless spectrum are one of the reasons they are so well-positioned to do this project.  This award is a major milestone and I congratulate them for this achievement.’Lieutenant Governor Brian Dubie said: ‘As of today, the funding puzzle is finally complete for making broadband service available everywhere in our state. Vermont’s e-State Initiative will be a reality, without new bonding authority or tax increases, but with a truly effective private-public partnership.’ Now, he said, ‘It will be up to us to focus on implementing the plan and getting the job done.’Dubie added, ‘This is a giant leap forward in our ability to retain, attract and grow good, new private-sector jobs all over our state.’Leahy, Sanders and Welch wrote to USDA RUS Administrator Jonathan Adelstein in May highlighting the VTel proposal and other Vermont proposals.Guite said the grant will allow VTel to offer high-speed Internet access over its wireless system to customers across the state ‘ including the Northeast Kingdom — for between $10 a month for light users, and $35 a month for regular users.  The grant will also accelerate VTel’s fiber build-out to its existing customers, throughout 14 towns across Southern Vermont, which will enable those customers to receive as much as one gigabit of service.  Guite says the funded project will also integrate Smart Grid improvements and will continue building VTel’s statewide fiber network.‘This is an almost breath-taking example of Senator Leahy, Senator Sanders, Congressman Welch, Governor Douglas, and Lieutenant Governor Dubie coordinating superbly, in a way that effectively brought more per capita ARRA job-creation funds to Vermont than came to almost any other state,’ said Guite.  ‘At VTel we are deeply grateful, and humbled by the scope of the challenge ahead of us.  WOW brings next-generation mobile broadband wireless to every one of Vermont’s 114,000 unserved residents, making Vermont the first state in America with universal Internet to everyone.  In addition, WOW brings to every existing VTel customer the first Google-envisioned GigE-over-fiber-to-every-home network in the western world.  Singapore is building the same, to be completed in 2014, and we hope to be done in 2012 or 2013.’Springfield Regional Development Corporation Executive Director Bob Flint, who assisted VTel in developing the original proposal to reflect the needs of area residents and businesses, said the grant will have an immediate impact on the area economy: bringing new jobs to Springfield ‘ where VTel is headquartered ‘ and creating a long-term infrastructure that will help area businesses grow and will attract new businesses.  “We’re very excited to show how cutting-edge fiber capacity will stimulate economic activity and property redevelopment in our region,’ said Flint.  ‘VTel has been a leader for years, and we greatly appreciate our economic development partnership.”  U.S. Secretary of Agriculture Tom Vilsack announced the $116 million Vermont project as part of $1.2 billion in American Recovery and Reinvestment Act broadband grants awarded Wednesday that will invest in 126 broadband infrastructure projects across the country. An additional $117 million in private investments nationwide will be leveraged by these Recovery Act funds, bringing the total nationwide investment to $1.31 billion.  The VTel grant and loan package account for nearly 10 percent of the national allocation announced Wednesday and is the second largest award announced today by Vilsack.The award is part of a $7.2 billion broadband investment that was included in the American Recovery and Reinvestment Act.  The USDA Rural Utilities Service was charged with awarding $2.5 billion of those funds to expand broadband access in rural America.  Last month, the U.S. Department of Commerce National Telecommunications Information Administration (NTIA) ‘ which also administered a portion of the Recovery Act broadband funds — awarded VTel a $13.7 million grant to expand the company’s mid-mile fiber backbone and connect anchor institutions.  The NTIA also announced a $33.4 million grant to the Vermont Telecommunications Authority (VTA).Leahy, Sanders and Welch noted that with the announcement of these funds, the American Recovery and Reinvestment Act has invested more than $235 million in Vermont’s utilities, including $69 million for Smart Grid improvements, $47 million in mid-mile fiber improvements, and $2.5 million in broadband adoption efforts.Source: Vermont Congressional delegation. 8.4.2010last_img read more

Australia sees biggest daily rise in COVID-19 cases

first_imgA medical professional administers a test to a member of the public at a pop-up COVID-19 testing facility on June 26, 2020, as the state of Victoria in Melbourne, Australia experiences a spike in cases. AAP IMAGE/REUTERS The growing figures have stoked fears of a second wave in Australia after several weeks of fewer than 20 new cases a day. In May, Victoria – home to more than 6 million people – began lifting restrictions imposed a month earlier to slow the spread of the virus. SYDNEY – Australia’s second most populous state said yesterday it is considering reimposing social distancing restrictions after the country reported its biggest one-day rise in new coronavirus infections in more than two months. While many states and territories have yet to report their latest numbers, Victoria said it has detected 75 cases in the past 24 hours – enough to make it Australia’s biggest daily outbreak since April 11. As cases have mounted, Victoria has embarked on a massive testing regime and the state’s chief health officer said the state is considering reimposing social distancing restrictions. It has pledged to remove the bulk of restrictions by the end of July. (Reuters)last_img read more

Familiar Territory: 1 year after losing the starting position, Nassib is back atop SU’s depth chart

first_img Comments Stepping under center with the first-team offense, Ryan Nassib remembered just how good this felt. As Syracuse opened spring practice March 22, Nassib’s name sat atop the depth chart at quarterback. But the sophomore wasn’t taking anything for granted.‘This year, I have a whole year under my belt,’ Nassib said. ‘I’ve been through a lot with the season. I’ve learned a lot and am executing a lot differently out on the field.’And once the 11-on-11 scrimmaging began on opening day, Nassib started solidifying his hold on the position that was taken from him before the start of last season.In just the first series of action, Nassib took a snap, side-stepped two rushing defenders in the backfield and unleashed a spiral downfield for a perfect 40-yard connection with wide receiver Alec Lemon. Despite drawing chest bumps and high-fives from the rest of the offense — and a raving chorus from the onlooking coaching staff — SU’s 6-foot-3 quarterback remained poised following the play. No high-fives, no clapping. Nothing. Instead of celebrating, Nassib did exactly what coaches have told him all his life and acted like he had been there before. A large part of his reaction was because, in reality, he had been.AdvertisementThis is placeholder textAnointed the starting quarterback in spring practice last spring before losing the job to one-year transfer Greg Paulus once Paulus arrived to campus in August 2009, Nassib still took most of his reps with the first-team offense last March. But a year later, this go-around feels different. Completely different.‘Last year was night and day compared to this year,’ Nassib said. ‘I came in last spring not knowing much, never really competing in practice, didn’t know any of the game situation.’ One year ago, Paulus transferred in for one season, and Nassib’s hold on the position disappeared. Once the fall rolled around, Paulus had entrenched himself as the starting quarterback. Nassib played in nine games, with varying results, and ultimately made as much as he could of his first year on the field.The difference this year, head coach Doug Marrone said, is ‘incredible.’In hindsight, Nassib said he now views last year’s situation as a good thing, a ‘learning experience.’ Though he obviously would have loved starting, he said the experience allowed him to step back and see what was going on out on the field, ultimately improving his game moving forward. And it is also what has given him the resolve to go out and ‘earn’ the job that has already been given to him. He knows all too well there are no guarantees when the fall rolls around.‘He obviously understood the situation last year, and he just worked hard all season knowing that he would have his chance again,’ center Ryan Bartholomew said. ‘And he’s going to make sure this time nobody can take it away from him. ‘You can tell in the way he prepares and the way he knows the offense.’Nassib has been looking forward to the start of spring practice ever since a 56-31, season-ending blowout loss to Connecticut on Nov. 28. With Paulus’ eligibility exhausted, the reigns to the offense are once again in Nassib’s hands. But that doesn’t mean there won’t be competition. Marrone didn’t recruit Nassib. But he did recruit second-string quarterback Charley Loeb and two of SU’s top recruits for this fall, John Kinder and Jonny Miller. And Nassib knows that.So instead of using the short offseason to relax, he instead used it to study up on the playbook, learn the nuances of a newly installed offense and increase his physical preparation, knowing he had to make the most of spring ball. This time, that hold on the position wasn’t going to be lost.‘Every spring there’s going to be pressure, there’s always going to be someone competing for the position you’re competing for,’ Nassib said. ‘And no matter who it is, there’s always going to be pressure. It’s always in the back of your mind. So you’ve always got to play your best because you know the other guy is going to play their best.’Like he did in the fall, Nassib still has Paulus in his ear, serving as what he refers to as a ‘positive reinforcement.’ And even more importantly, he has Marrone tutoring him on the nuances of the newly installed offense. That is what Nassib views as the most valuable benefit of having his head coach as his offensive coordinator.And that, he believes, will make him a better quarterback when the fall rolls around. Starting middle linebacker Derrell Smith has known Nassib can play since his true freshman year. He still recalls Nassib ‘torching’ the starting defense as the scout team quarterback. But after a year under his belt, and some successful in-game experience in tote, Smith is seeing even more this spring.‘He’s a big leader now,’ Smith said. ‘He’s honestly a true leader for us now. When we need a play, we feel like we can look to him and say, ‘Ryan, we need a touchdown,’ and he’ll do it. He’s just got that swagger to him this year.’Linebackers leading defenseLed by Smith, Syracuse returns its core group of linebackers from last season. And during the first week of spring practice, the chemistry of the unit is already showing. Following a Smith interception that was run back for a touchdown on March 24, the defense swarmed the middle linebacker and the chest bumps started. As did the noise.‘We’re out there knowing everything is on us,’ linebacker Ryan Gillum said. ‘Just being around each other and playing together, we have fun all the time, yelling and screaming and getting to the ball. We’re having a lot of fun.’Each time one of the linebackers would get an interception, a big block or a fumble recovery, the chirping started. Smith said that after a year playing together, and a year in the current defensive scheme, they’re just out there having fun.‘Now it’s more like a competitive nature, so we pretty much compete against each other,’ Smith said. ‘After a play we come up like, ‘Yeah, I got that tackle,’ or, ‘Yeah, I got that sack.’ We just go out there and play rather than thinking too much.’Marrone likes what he sees with this group. He said the competitive nature and intensity out on the field has been good for the team, and he’s looking forward to what could be a strong season for the unit.‘They’re all players that have a chance to have honors after the season,’ Marrone said. ‘I just think they’re getting better and better and they feel more comfortable, obviously, than they were a year ago. We’re looking for very productive play out of those positions.’[email protected] Published on March 31, 2010 at 12:00 pmcenter_img Facebook Twitter Google+last_img read more

Using Sand to Store Solar Energy

first_imgMore research would be helpfulChlupp has been experimenting with insulated thermal mass for years, and concedes that it’s not easy to incorporate the feature into energy modeling. Nor is there much research available. Yet he finds the system works.“I walk away from my house at 40° below and come back in the spring and don’t worry about it,” he says. “Sand and slabs can be a very bad idea but if designed right they can also offer great benefit from my experience…and it is my firm believe that we need to look at insulated internal mass in cold climates carefully as it can help us to make our buildings function better. I will leave it at that.” John Klingel’s question was simple enough: what’s the best way of heating up a thick bed of sand beneath a concrete slab with PEX tubing? But the underlying issue — whether a sand bed is a good idea in the first place — quickly takes center stage in this Q&A post at GreenBuildingAdvisor.Klingel plans to include a 2-ft. thick bed of sand between his concrete slab and a layer of rigid foam insulation. The sand is a heat sink, but Klingel isn’t sure where the PEX tubing should be located for the best result. Nor is he sure what diameter the tubing should be, or what the spacing of tubing in the sand will work best.Some writers think a sand bed is a waste of time. Others report they’ve had good luck with them, even in extreme climates. That discussion, similar to an exchange on the Q&A forum last year, is the subject of this week’s Q&A Spotlight. Can Heat Be Stored in a Sand Bed Beneath the House? Q&A: Higher solar heating fractions?Energy Efficient from the Ground Up (Fine Homebuilding)Zero Energy, Infinite Appeal (Fine Homebuilding) RELATED ARTICLES Even so, the plan has holesBe that as it may, says Holladay, but there are still some problems with this approach. First, where do you put the sub-slab insulation, and, second, how do you control the flow of heat from the sand to the slab?“If you have no insulation between the slab and the sand, and you are dumping solar heat into your slab in July and August, then heat will flow from your hot sand to your slab in July and August,” he says. “That may work in Fairbanks, but it won’t work in any climate where summer overheating is a potential problem.”Also, if you’re trying to keep the interior of your house plus tons of sand warm, you’ll need that much more heat input. That’s not an issue if heat is free, but you should factor in the cost of solar collectors plus pumps, controls and electricity to operate the system: “Bringing tons of sand up to temperature, and maintaining the sand at an elevated temperature, takes heat. If I build a house without that heating load, my annual heating load will be less than yours.” Video: DIY ICF House With Hydronic Floor To get a useful amount of heat from the sand during the coldest months of the year, he says, it must be hot enough to get water in a hydronic heat distribution system to at least 100°F. And that, he adds, just isn’t going to happen.“The sand doesn’t get that hot — or if it does, it doesn’t stay that hot from early September (when it is likely to be hottest) until mid-November (when you begin to need it),” Holladay writes. “Moreover, the pumping energy is a big energy penalty — parasitic energy that needs to be considered when analyzing possible benefits. Finally, the capital costs of all those extra solar collectors is high — an investment without a significant payback.”Indeed, keeping the sand warm enough when solar energy is not enough is also on Klingel’s mind. “My plan, if I go this way, is to heat the sand with the wood gasification boiler as well as passive solar,” he says. “However, when the wood boiler is not running and solar is not enough, my propane boiler, which will heat the slab, is going to have to work its butt off.”He adds, however, that the temperature of the sand probably won’t have to be that high because it won’t be used for an active heating system, just storing heat for the night, or at most for a couple of days. Presumably the sand would gently warm the slab without an active distribution system, and in this case he thinks a temperature of between 80°F and 85°F would be enough. An expert opinionThis week GBA invited energy expert Mark Sevier to comment. A former employee at the Building Science Corporation, Sevier designed, built, and lives in a net-zero energy home outside of Boston, Mass.Mark Sevier writes:“Martin is right. Martin’s perspective is most accurate as it relates to ‘direct thermal storage’ systems (ones without heat pumps) – long-term thermal energy storage systems should be subject to monitored skepticism, as the numbers on paper don’t work on a straight heat-loss basis. There are a lot of hours between summer collection and winter loss, and in general thermal storage of building materials inside insulation can be measured in days, not months. Huge masses of water or sand might make weeks, but a wise person starts to consider that things have gotten out of scale and a house has turned into an expensive experiment more than a cost-effective place to live.“An example to prove the point. Take for example a 5,000-gallon reservoir of water, a 6,000 HDD climate, and a house heat-loss coefficient of (UA) 100 BTU/h (which is unrealistically small for most buildings). Heating the building for the season will require 6000 HDD x 100BTU/h x 24h, or 14.4 Million BTU/yr. Water stores 1 BTU/lb-F, so 5,000 gallons store 41,650 BTU/F. Now divide 14.4 million BTU by 41,650 BTU/F, and assuming zero undesired tank losses, the water will need to be 346 F hotter at the beginning of the season than the end of it, unless there is a phase change (which there would need to be). This doesn’t work, and a 200-300 BTU/h load is more reasonable for most efficient houses, doubling or tripling the seasonal storage requirement.“More realistically, a 5,000-gallon reservoir connected to solar collectors might be running in the 180 to 80 F range (note that you’ll have 180 F when you don’t need heat, and 80 F when you do), or about 4.16 million BTUs ‘peak to valley’ storable in said tank, about 1/3 of what the really efficient building above would need. Of course the sun will shine during the winter, and your solar thermal system will run (unless it’s dark), but it will be running on daily energy by mid-winter, not seasonal energy, since the tank will be depleted by 1/3rd or 1/2 of the season (not considering tank losses closely, which will result in overheating the house in early winter, and further shortening of the ‘seasonal’ nature of the tank since overheating leads to larger hourly loss).“The only monitored-to-work seasonal storage system that I’ve ever heard of was MIT Solar 1, built in the 1930’s – it had a tripled glazed collector for a roof on a 500 sq. ft. building with an 18,000 gallon tank in Boston’s 5500 HDD climate. Otherwise, I’ve heard conceptual anecdotes with data gone missing.“For seasonal storage you need a heat pump. My observation is that for ‘seasonal storage’ to realistically work (i.e. not an expensive experiment), you need a heat pump. I followed someone’s conceptual sales job, and I have a large solar thermal system and seasonal storage experiment I’ve already committed to, but I can see that using outside air is the best / cheapest approach toward seasonal storage – an air-source heat pump (or ground source works too, if you like putting pipe in the ground and have extra cash to get rid of).“What really works is a grid-tied photovoltaic system. Using solar thermal systems for space heating is not a good investment, since that expensive hardware sits idle through the summertime, and then likely can’t meet the load in the winter. Solar thermal panels can collect more solar energy per square foot than PV panels (as much as 2 to 4 times), but they need a load to work against, which they don’t always have – if the tank is already hot, they collect nothing. Grid-tied PV panels, on the other hand, can always send energy back through the electric meter, storing that energy with no losses in their power bill until it is needed in the off-season. PV panels + a heat pump operating with a COP of 2-4 end up equaling the solar collection efficiency of solar thermal panels, and no losses from lack of summer load or huge storage tanks to buy and install.“So, my suggestion to anyone with limited financial resources wanting to have a solar-powered back-up heating system is to install a properly sized grid-tied PV system and air-source or ground-source heat pump. For the off-grid folks, go with firewood and solar panels for DHW and electricity needs. No expensive hardware sitting idle = well invested money. Solar panels sitting idle = lousy investment.“It’s not that passive solar doesn’t work. I like passive solar things more than the next person, but I realize passive solar isn’t for everyone nor every site – privacy, glare, overheating, management of window insulation, condensation on windows, etc. are all issues that come with it. More often than not, the passive solar buildings I ride by have been largely defeated due to some issue unrealistically considered by an enthusiast. The enthusiast will live with their choices, and ‘sail their ship,’ but there aren’t so many people in this group. Most people seem to be in the ‘set it and forget it’ camp, since they have lives beyond meeting home heating needs.“My experience has been that the most important factor in the anecdotal success of uncommon systems is how much the advocate has invested in them, both financially and reputation-wise. I built a system that I subsequently figured out didn’t make the most sense – why can’t others discuss the shortcomings of their experiments? People must like story-telling more than science.”Mark Sevier, PE Podcast: How Heat Moves Through HousesPodcast: Solar Thermal: Types, Cost, and Investment Advice Forget the idea — it won’t workCount GBA senior editor Martin Holladay among those who think that an insulated sand bed doesn’t add much to solar design. “Here’s my opinion — subject to revision when someone gives me good monitoring data to contradict my statement: you can put the PEX wherever you want, because these systems don’t really work,” Holladay tells Klingel. RELATED MULTIMEDIA You’re missing the point, an advocate saysTo Thorsten Chlupp, whose description of his SunRise Home is the subject of a separate Q&A post, Holladay’s reply is an “apples vs. oranges” conversation.“If you want to be able to capture and utilize passive solar gain there is in my experience no better way of doing this then with adding INSULATED mass to the foundation,” he says. “A layer of sand between the slab insulation and the actual concrete slab is the cheapest and most economical way to do so. I added 180 tons of mass for $380 in material costs at the SunRise home.”The sand bed does three things, according to Chlupp: provides an insulated heat sink for passive solar gain; keeps all of the under-slab plumbing in a conditioned space while minimizing thermal bridging; and, as an option, can provide active heat storage if secondary solar heat lines are installed.“Anyways, I argued these points before and probably will do so many more times as it seems an alien concept for many,” he says. “I have independent data collection on my system and that might bring a bit more weight to this argument in the near future. To me at least the fact that I have not actively heated my home since 02/16 besides passive solar gain in temperatures well below freezing kind of proves that this concept works fairly well if it is implemented right.“I never even had to load my sand bed actively this spring as it stores the sun’s energy so well that my slab is over 70°F – my kids run around barefoot all day on it, nice and comfy… Passive solar energy is the only free energy there is and should be the very first source we should always tap into in a heating climate.”He promises Holladay to send data as it becomes available, but points out also that the sand beds are “strictly passive heat sinks.” Once heat is dumped into the sand, it moves toward cooler a surface all on its own. “There is no control, nothing to extract,” he says.“Heat in – heat out by temperature differentials is all there is to it and it takes some figuring out on finding your comfort zone as it functions and reacts very slowly. If you’re trying to use it as an active storage – like a rock heat bank – I agree with you, it makes no sense and is not feasible. “last_img read more
