STM plans to build solar-powered bus shelters Panels could be used to power lighting * and illuminate revenue-producing ads By Monique Beaudin, The GazetteFebruary 2, 2009 Montreal’s public-transit agency is planning to spend $14.4 million to buy 400 new bus shelters – some of which would use solar panels to provide electricity. The new shelters need an energy source to allow the Société de transport de Montréal to use new tools to provide customer service and advertising. In some cases the shelters would be powered by solar energy, in others the shelters would be linked into a local source of electricity. Several other cities – including London, Vancouver and Toronto – already have bus shelters that use solar panels to charge batteries that power their lighting systems. Blainville, north of Mont-real, put up four such shelters in October and plans to replace all its bus shelters with solar-powered ones by 2010, said spokesperson Yves Meunier. Blainville’s plan was to make their bus shelters self-financing, by using revenue generated from selling advertising in the shelters. For that they needed an energy source to illuminate the ads. “People selling advertising want the ads to be visible for a certain number of hours every day, especially during the winter,” Meunier said. Blainville’s bus shelters – which cost about $30,000 each – were designed and built by a local firm, Meunier said. The city will recycle the old shelters by selling them to other municipalities, he added. The STM also expects that by selling ad space in its new shelters they’ll pay for themselves over a 10-year period. While the STM has already tested several different kinds of solar-powered bus shelters, spokesperson Isabelle Tremblay said the agency hasn’t chosen a specific bus shelter model to buy yet. The transit agency is still waiting for the results of a bus-shelter design contest announced by Montreal Mayor Gérald Tremblay last September. Tremblay called on the city’s designers to come up with new ideas for five things – the Champs de Mars métro station, the eastern wall of the courthouse, bus shelters, taxis and temporary festival furniture. Design Montreal has not yet launched the contest, spokesperson Stéphanie Jecrois said yesterday. The agency is still meeting with its partners to determine how the contest will work, but she said the contest details should be announced with a few weeks. The contest will be held in 2009, she said. Meanwhile, at the STM, Tremblay said the agency will only go to tender for new bus shelters after the Design Montreal contest wraps up. The STM now has 2,977 bus shelters, serving about one-third of its bus stops. It would like to install 100 new bus shelters over the next two years, and 100 more each year from 2011 to 2013. mbeaudin@thegazette.canwest.com © Copyright © The Montreal Gazette

Hot new Vdara hotel might be a little bit TOO hot Bill Pintas was vacationing in Las Vegas when he decided to stay at the swank new Vdara hotel, a curvy 57-story tower owned by MGM Resorts. He was sitting at the pool when he encountered something alarming. He recalls, "I'm sitting there in the chair and all of the sudden my hair and the top of my head are burning. I'm rubbing my head and it felt like a chemical burn. I couldn't imagine what it could be." Like an ant under a magnifying glass, he remembers running to an umbrella, but being unable to escape the hot light. He recalls, "I used to live in Miami and I've sat in the sun in Las Vegas 100 times. I know what a hot sun feels like and this was not it. My first inclination was thinking: Jesus we've destroyed the ozone layer because I am burning." Speaking with employees, he was alarmed to find out that the hotel staff was aware of the situation. He recalls, "They're kind of giggling and say: 'Yeah, we know. We call it the death ray." The "death ray" appears to be created by the glass surface of the hotel itself -- acting as a concentrating parabolic dish -- similar to those used to heat water to a boil in solar power systems. The dish concentrates light on a 10-foot by 15-foot hot zone moving across the pool. Temperatures in this area spike 20 degrees Fahrenheit -- or more. Bill Pintas saw his plastic newspaper bag literally begin to melt. The bag -- composed of polyethylene -- is designed to withstand temperatures of up to 120 to 130 degrees Fahrenheit. And the employees recall seeing plastic cups -- which have a melting point of 160 degrees Fahrenheit – actually melting. Other guests, including newspaper reviewers, have also observed the burning beam. The hotel management doesn't call it a "death ray", they prefer the more friendly distinction "solar convergence phenomenon". Gordon Absher, a spokesman for MGM Mirage says the hotel is addressing the problem, and comments, "Because of the curved, concave shape of that hotel, they sometimes get isolated pockets of high temperatures." The hotel is baffled by how to solve the problem of the "death ray", though. When initially constructing the building, they anticipated the issue and put a coating over the glass that absorbs 70 percent of the daytime sunlight. However, that was not enough to reduce its painful effects. And the ray sweeps across a wide area, making it hard to protect a specific region. Comments Mr. Absher, "This is quite literally an astronomical challenge," Absher said. "We are dealing with a moving target." The mishap in architecture isn't as glaring as some of history's most notable mistakes -- such as the 1940 Tacoma Narrows Bridge, but it is pretty extraordinary. It serves as a reminder that while many take the science and engineering of designing massive skyscrapers for granted these days, it remains a tricky business. It looks like the Vdara may have exposed the wrong guest to the death ray, though -- Mr. Pintas is a Chicago-based lawyer. http://www.dailytech.com/Hotel+Accidentally+Makes+Solar+Death+Ray+Burns+Lawyer/article19756.htm -
I'm not sure if this is "urban tech", in that it probably isn't something that's applicable in a variety of scenarios, nor if it has already been talked about on this site, but regardless, i still think it's worth mentioning. -------------------- Solar City Tower for Rio Olympics is a Giant Energy Generating Waterfall by Bridgette Meinhold, 03/19/10 This renewable energy generating tower located on the coast of Rio is one of the first buildings we’ve seen designed for the 2016 Rio Olympics, and boy, is it crazy! (In case you didn’t notice, it’s also a waterfall.) The Solar City Tower is designed by Zurich-based RAFAA Architecture & Design, and features a large solar system to generate power during the day and a pumped water storage system to generate power at night. RAFAA’s goal is that a symbolic tower such as this can serve as a starting point for a global green movement and help make the 2016 Olympic Games more sustainable. The self-sustaining tower for the 2016 Olympic Games is designed to create renewable energy for use in the Olympic Village as well as the city of Rio. A large solar power plant generates energy during the day. Any excess power not used during the day is utilized to pump seawater into a storage tank within the tower. At night, the water is released to power turbines, which will provide nighttime power for the city. On special occasions water is pumped out to create a waterfall over the edges of the building, which RAFAA says will be, “a symbol for the forces of nature.” Info on the size of the solar and pumped water storage system is not available yet. Access to the eco tower is gained through an urban plaza and amphitheater 60 meters above sea level, which can be used for social gatherings. On the ocean side of the 105 meter tower (behind the waterfall) is a cafeteria and shop. An elevator takes visitors up to the top floor where an observation deck offers 360 views of the ocean and city. At level 90.5, a bungee platform is available for adventurous visitors. Link to article: http://www.inhabitat.com/2010/03/19/solar-city-tower-for-rio-olympics-giant-energy-generating-waterfall/ -------------------- if for nothing else, the renderings look kinda cool. wonder if you could have such a waterfall flowing off our own olympic tower ? or would that risk to bring in even more toilet jokes ? .. .. -
Solar shingles from Dow Chemical make Top 10 tech list By Jeff Kart | The Bay City Times October 12, 2009, 2:44PM The Saginaw News A concept illustration of the Dow Chemical solar shingle. A clean tech blog called CleanTechnica has a post up on the "Top 10 Solar Technologies to Watch Out For." Coming in at No. 3: "Solar Roof Shingles, Printable and Paintable Solar Panels ... Solar shingles, by Dow Chemical, should be available in limited supply by mid 2010 and then readily available by 2011, says the company." Dow officials showed off the company's solar shingles to Gov. Jennifer Granholm in Midland earlier this month. The company launched a $53.5 million solar shingle initiative in 2008, with help from a $20 million U.S. Department of Energy grant. http://www.mlive.com/mudpuppy/index.ssf/2009/10/solar_shingles_from_dow_chemic.html

Solar power trash bins hit Montreal streets Last Updated: Monday, May 28, 2007 | 5:30 PM ET CBC News The BigBelly garbage cans use solar panels to generate power. (Steve Rukavina/CBC) The City of Montreal is going solar in its bid to clean up downtown streets. The Ville-Marie borough has launched a pilot project starring BigBelly, a "green" garbage can that uses cordless compaction technology. The sun-powered trash cans compact garbage using solar energy, and can hold up to five times the volume of regular garbage cans. Compacting garbage reduces the need for trash collection and could decrease the all-too-common Montreal sight of overflowing rubbish bins.
