Daan Roosegaarde has been touring China with his Smog Free Project , showcasing the Smog Free Tower and encouraging people to find innovative solutions to address air pollution . He’s not out of ideas yet though; he’ll add to his tour with new smog-sucking bicycles . These bikes could work much like his Smog Free Tower does, absorbing dirty air , cleaning it, and pouring it back out as fresh air. Biking in a city polluted by smog isn’t healthy, so people are less inclined to ditch their cars and opt for a bicycle. Roosegaarde envisions an answer to that problem in a bike that can inhale dirty air, clean it, and pump it out around a cyclist. Related: China’s crazy smog-sucking vacuum tower might actually be working In a statement, Roosegaarde said, “ Beijing used to be an iconic bicycle city. We want to bring back the bicycle as a cultural icon of China and as the next step towards smog free cities.” The studio says the concept aligns with growing interest in bike sharing programs in China – like Mobike , which has over a million shareable bicycles in the Beijing area. There’s still a long way to go to slash pollution and traffic in the country’s capital, but the smog-sucking bicycle could offer a creative approach to the problem. The Smog Free Bicycle found its beginnings in a Studio Roosegaarde-hosted workshop at contemporary art museum M Woods in Beijing, featuring Professor Yang of Tsinghua University and artist Matt Hope, who worked on an idea for an air-filtering bike around four years ago . According to Studio Roosegaarde, the new smog-sucking bicycle is “currently in the first stage and is intended to become a medium for smog free cities, generating clean air by pedaling, and creating impact on the larger urban scale.” + Studio Roosegaarde Images via Studio Roosegaarde and Wikimedia Commons

Comments Off on London breaks legal limits on air pollution in just five days in 2017

London isn’t the best place to take a deep breath right now. Lambeth’s Brixton Road broke annual air pollution limits in only five days in 2017, with other areas likely to follow. Campaigners and even a spokesperson for Mayor Sadiq Khan are calling for action to curb dangerous pollution in the city. The law in London is that hourly levels of nitrogen dioxide (NO2) must not pass 200 micrograms per cubic meter more than 18 times in one year, but Brixton Road already broke those limits. The Lambeth location won’t be the last; Oxford Street, the Strand, and Kings Road in Chelsea are three other pollution hotbeds, and The Guardian said Putney High Street exceeded the hourly levels in 2016 more than a staggering 1,200 times. Related: New Delhi has the worst air pollution of any city on earth Diesel vehicles are the “single biggest source” of London’s air pollution, according to Greenpeace . The activist organization recently flew a masked Mary Poppins over Parliament to call attention to the dire issue that puts children and adults’ health at risk. They noted air pollution isn’t just concentrated in London: “Last year, people in 169 different places in the UK – from Calderdale to Caerphilly – breathed illegal levels of pollution.” ClientEarth lawyer Alan Andrews, who resides in Brixton, told The Guardian , “This is another shameful reminder of the severity of London’s air pollution and shows why the mayor has rightly made tackling it a top priority. It is absolutely essential that he now delivers on his promises and that the national government back him to the hilt.” It’s time for London to clean up its air, and Mayor Sadiq Khan has said he’ll double funding, spending £875 million – or over $1 billion – over five years to combat the issue. Let’s hope that money’s well spent. Via The Guardian Images via DAVID HOLT on Flickr and Wikimedia Commons

Comments Off on 5 micro wind turbines that can have a big impact on the environment

Mahashweta Patra: Micro wind turbines Micro wind turbines that can have a big impact on the environment Wind energy generators have been around for centuries in various shapes and sizes. But as the eco-friendliness becomes a constant topic for concern, the wind energy generator or windmills are moving up in the preferred list of those concerned about energy and environment. Wind is one of the natural and renewable sources for thermal power generation. Scientifically, it is defined as conversion of kinetic energy (the motion energy) into mechanical power. However, large sized wind turbines are mainly suitable for the sea side or hill top areas. Therefore, many micro wind turbines (about 5+ meter of height) have been designed and have become very popular for generating sufficient electric power. Micro turbines are mainly suitable for off-grid places, where national grid electricity can not be accessible. The entire process comprises of the storage of generated electricity first in battery banks and then the circulation of the energy via inverters in the form of 240 A.C electricity. When it was realized that micro turbines were not apt for urban areas, basically because of its noisy generator and poor functionality in low average wind speed, micro wind turbines became very popular. The micro wind turbines also provide an additional support to national grid electricity for specific areas. The micro wind turbine can be fitted on the roof tops conveniently and is capable of producing enough power for basic household consumption. These micro wind turbines are quieter with minimal vibration than the conventional turbines. There are several domestic micro wind turbines such as Windsave 1000 and D400 StealthGen, which are available in cost effective rates and are eco-friendly as well. Here is the list of various types of micro wind turbines: 1 . Skystream 3.7– The Original Skystream Personal Wind Turbine Skystream 3.7 The Original Skystream Personal Wind Turbine Skystream 3.7 wind turbine is well suited for homes and business areas. The most exciting feature of this energy generating machine is that, it functions even in low wind environment. It is a user friendly machine and can be easily controlled with the help of Skyview monitoring software installed in your computer system. This Skystream 3.7 comes in a sleek and modish design and there are monopole towers of varied lengths. Good efficiency even in low wind speed (due to presence of special blades which are swept shaped) and excellent durability with easy to operate are some of the highlights of this micro wind turbine. It also comes with a warranty of 5 years. The entire set up is capable of producing 400 Kilowatt hours of electric power per month and is highly recommended for schools and government buildings. 2 . Bergey Excel Excel Bergey Excel Bergey Excel was introduced first in the year of 1983. This wind turbine is installed at around 1,800 sites across the world till date. Recently, this specific turbine has been upgraded with powerful alternator and larger blades to enhance its efficiency and performance by 25 percent. This machine basically designed with around 7-meter diameter is estimated to produce approx 10,000 W power. Bergey Excel wind turbine is available in two configurations: grid-connected and battery charging form. It is highly reliable turbine and requires very low maintenance and functions in the adverse weather conditions as well. Also available with varied height towers (18m to 43m) and bending versions, these micro wind turbines are also offered as per your location. It is highly recommended for locations like Eco- tourism resorts, larger tele-communication sites, big rural areas, remote villages and places with lesser facilities. The price ranges varies from 25,770$ to 31,770$ due to upgradation with a voltage regulator or a grid synchronous inverter 3 . Whisper 500 Whisper 500 Micro wind turbine The Whisper 500 turbine is specifically designed to encounter the harsh and high speed wind conditions. The attention has been paid to its extraordinary design, which includes two blades with fiberglass reinforced design. The component named angle governor helps in protection of the turbine by turning the blades and alternator out of the wind. As a result, there is less exposure of turbine in high speed environment conditions. The side-furling angle governor basically helps in carrying out smooth functioning of the turbine resulting into the high yield of energy by this machine. It produces around 500 Kilowatt Hours of power every month with the wind speed of 12 mph. The only drawback of this machine is that it is not suitable for the installation in marine areas. 4 . AeroVironment Architectural Wind Architectural Wind AeroVironment Architectural Wind This particular kind of turbine is quite different from the conventional wind turbines, specifically in terms of design. The AeroVironment Architectural Wind design is such that it can contribute in easy production of thermal energy. It is mainly designed for commercial buildings and can also add up to the architectural beauty of the building. This micro turbine is to be placed at specific positions of the building to take the complete advantage of accelerated wind that eventually results into 50 percent maximum production of thermal energy than the power generated by the systems located outside the acceleration zone. This clean culture of power generation is very popular and adapted by most of the commercial offices. 5.Southwest Windpower AIR X marine AIR X Southwest Windpower AIR X marine Southwest Windpower AIR X marine is considered as the latest evolution in the history of micro wind turbines. The AIR-X turbine is the world’s largest selling turbine so far. The special features associated with this machine make it more advanced and popular in contemporary time. The additional features include a micro-processor to regulate the speed that helps in enhancing the performance, advanced body charging capability and reduction in loud noise generated by the device. The controller attached to the main machine helps in keeping a track of the wind by controlling the function of the alternator. The main function of the cubic curve alternator is to generate the energy to be delivered to the battery. The smart controller of the turbine helps in proper movement of the blades and reduces the possibilities of flutter noise. Recently, a new range of carbon reinforced blades with optimum angle direction has been introduced. These are very useful in increasing power production. The noise system is basically controlled by the efficient electronic circuit system of this micro wind turbine type. For example the electronic circuit system slows down the blades in case of heavy winds. Apart from this, special battery set up has also been introduced which mainly focuses on high battery durability and no overcharging. Any battery size bank between 25 amp-25,000 amp hours or higher can easily be associated with this kind of turbine. Also there is a special auto brake feature to slow down the AIR-X turbine to silent spin when the battery is fully charged and indirectly also helps in reducing noise. The highlight of this turbine system is that a manual switch on-off control option is attached to it. This wind turbine design is highly resistant to any critical situation of wind, sun and water and does not require any additional support of a tower.

Sreejith Nair: Carbon footprint How to calculate your carbon footprint The project Using fossil fuels and electric appliances creates carbon emissions. Using refrigeration agents produces carbonized waste gases. Certain industries like small scale industries do open-air combustion activities. Combustion creates carbon monoxide that is absorbed by the atmosphere causing it harm. Resources required An excel sheet to track your carbon emissions, online carbon footprint calculator, electronic calculator. Instructions 1) Check how much electricity you have consumed Review your electricity bill. If you do not know how to figure out the stats of your electricity consumption, check with your local electricity supply company on how to read and understand it. Check the kilowatt usage in hours. Fill this number in an online carbon footprint calculator. 2) Check your gasoline expenses Gasoline cripples the environment with heavy emissions that come from exhausts of vehicles. That is why go-green initiatives stress upon the usage of public transport or hybrid vehicles to commute. Check your gasoline expenditure in a month. Enter your car’s make, model, and the volume of gasoline consumed in the online carbon footprint calculator. 3) Air travel creates tremendous carbon footprint Airplanes consume humungous amounts of fossil fuel. But it cannot be helped, because without it airplanes would not fly! But one thing that can be helped is to reduce your airline travel. Check how many times in a month or year you took an aero plane to travel. 4) Review your daily eating consumption Buying imported ingredients or food creates carbon footprint. Buying locally grown vegetables, fruits or general food does not. Calculate which categories of food you eat fall in the former category. 5) Download a carbon footprint calculator This is actually the first thing you should do. There are various types of carbon footprint calculators. Download one from the internet. Use one that is applicable to you. You may want to calculate the carbon footprint for your house, or for your firm. Both of them have separate carbon footprint calculators. To get more assistance on this contact your local environment control board or agency. They will be able to give you more guidance on this. They may have a very good carbon footprint calculator with them. Things to watch out for Walk to work or use the bicycle to reduce your carbon footprint. When you drive, do not accelerate suddenly and brake randomly. Use lighting and electric appliances that consume less electric energy.
