    carbon filters
  • (Carbon filtering) Carbon filtering is a method of filtering that uses a piece of activated carbon to remove contaminants and impurities, utilizing chemical adsorption.

  • (Carbon Filter) Carbon filters are most effective at removing chlorine, sediment, and volatile organic compounds (VOCs) from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds. Typical particle sizes that can be removed by carbon filters range from 0.

  • (Carbon Filter) Cartridge or cassette filled with activated charcoal, used to filter contaminants from the air. Required in ductless range hoods, as it will remove other contaminants after airborne grease has been absorbed by grease filters.

  • Activity involving mental or physical effort done in order to achieve a purpose or result

  • Such activity as a means of earning income; employment

  • exert oneself by doing mental or physical work for a purpose or out of necessity; "I will work hard to improve my grades"; "she worked hard for better living conditions for the poor"

  • A place or premises for industrial activity, typically manufacturing

  • activity directed toward making or doing something; "she checked several points needing further work"

  • a product produced or accomplished through the effort or activity or agency of a person or thing; "it is not regarded as one of his more memorable works"; "the symphony was hailed as an ingenious work"; "he was indebted to the pioneering work of John Dewey"; "the work of an active imagination";



The winning schools of An Taisce Green Schools Energy Project sponsored by ESB Electric Ireland were announced at an event in Tailors Hall, Dublin today attended by Minister of State for Communications, Energy and Natural Resources, Fergus O’Dowd. The overall winner was St. Catherine’s Senior Girls’ School in Cabra, who partnered with their catering company, Glanmore Foods to consider how the business could improve energy efficiency and reduce its carbon footprint.
The young students, aged between 7 and 12, from St. Catherine’s Senior Girls’ School conducted a site visit and energy efficiency audit at Glanmore Foods and proposed a range energy-efficient sestions including: turning appliances off standby, changing to CFL light bulbs where possible, turning machines off when not in use in the factory and encouraging staff to walk and cycle to work.

Furthermore, the girls calculated that the school used 15,170 plastic water bottles each year, which they felt was wasteful, so together with Glanmore Foods they considered some energy efficient alternatives and are now fitting water filters in each classroom. This has resulted in a reduction of bottle usage to 189 per year, leading to a massive energy saving as the bottles no longer need to be produced or recycled. In recognition of their creative solutions, the school was awarded the top prize of €4,000 by Susan Kinane, Business Markets Manager, ESB Electric Ireland.

An Taisce Green-Schools Energy Project sponsored by ESB Electric Ireland is a schools initiative that educates young people about the benefits of energy efficiency. The project is targeted at national schools that are already in the An Taisce’s “Green Flag” programme and brings local businesses and schools together to demonstrate the practical application of energy efficiency.
This year saw schools from all over the country partnering with local business, such as Colgate Palmolive and the Nenagh Guardian, to develop projects illustrating the practical application of energy efficiency.

Speaking at the prize giving ceremony Susan Kinane of ESB Electric Ireland said: “ESB Electric Ireland is committed to working with businesses and households to improve energy efficiency and reduce waste. The ease with which the companies were able to adapt to the children’s energy conservation sestions demonstrates how simple improving a business’s energy usage can be. Each year we see that young people have the creativity and determination to seek solutions that will enhance how we consume electricity. I would like to congratulate all of the students that submitted projects this year; the standard was very high and choosing an overall winner was a difficult task.

Minister of State, Fergus O’Dowd said: “Energy awareness is critically important in today’s world, and giving young people an understanding of energy efficiency and conservation is an important aspect of their education. I would like to congratulate the work done by An Taisce through the Green Flag programme in making learning about energy and environmental protection both interesting and relevant. I would also like to commend ESB Electric Ireland as without the support of big-business, projects like this do not happen. I would like to congratulate all of the schools who submitted projects and indeed the businesses that worked with them – in these times energy efficiency also means reduced cost for business and so it is something that is relevant to everyone.”
Speaking at the event, Patricia Oliver, Director, An Taisce said: ““Yet again the innovative ideas of our Green-Schools students have resulted in positive actions that make a real difference to our environment. The ESB Electric Ireland Green-Schools Energy Project gives the students an opportunity to affect change in their wider community. Our research shows that the 2040 schools working on the Energy theme have reduced their energy costs by on average 22% - resulting in cost savings of €2,400 per school per year. This sests savings of over €5million in energy costs made by schools with Green Flags in Ireland. The hard work, support and dedication of our schools and our sponsors make the huge success of the programme possible”

Sheila Ryan, a teacher at St. Catherine’s Senior Girls’ School said of the project: “Saint Catherine’s Senior School is a DEIS Band 1 School and it was great to see the children taking part in such a valuable learning experience. The response by Glanmore Foods was so positive and really boosted the children’s self esteem. We are planning on re-visiting the factory to see the changes in real life over the next couple of weeks.”

•St. Thomas’ S.N.S., Jobstown, Tallaght, Dublin 24 who partnered Colgate-Palmolive
•The Monastery School, Tipperary Town who partnered with Tipperary Co-Op

Toyota Celica: Ver 3.0

Toyota Celica: Ver 3.0

My 2003 Toyota Celica GT-S. Shot with a Nikon D50, equipped with an 18-200mm VR lens and circular polarizing filter.

The effect on this image was accomplished usign Photoshop CS3 by running the tone mapping process multiple times, each at mild settings. I use the tone mapping plugin from Here is my technique:

1. Start with an image (RAW if possible) that has a fairly dynamic range of colors already and make sure the brightness, contrast, shadows, saturation, and exposure are acceptable. The better the photo looks BEFORE tone mapping, the better it wil look after!

2. Convert to 32-bits and run the Photomatix Tone Mapping plug-in. Use relatively mild settings just to get a soft effect. You will do multiple passes, so don't try to get an extreme effect on the first pass.

Play around with the settings until you get a nice subtle effect.

3. Copy the image and paste it into a new 8-bit document. (You have to select 8-bit on the new document screen). if you just convert the 32-bit image to 8-bits, you'll get weird dots and lines in your image. There may be a better way to do this, but this method works perfectly every time.

4. Convert this new document back to 32-bits and run the Tone Mapping again. This time, the picture should have a more "artistic" appeal to it.

You have to play around with the settings during each conversion to get the right results. I usually set strength and Microcontrast (micro tab) to max. The most important other setting to play with is "Light Smoothing". For the first conversion, I usually use Medium to Very High light smoothing.

Sometimes, I repeat the process 3 or 4 times until I get the desired result.

P.S. - I did all this on accident and spent 3 hours trying to figure out what I did!
