Guest Post by Maria Kruk, an author for Patentsbase.com

Search of new renewable energy solutions has embraced most of the countries recently. Indeed, growth of oil and gas prices and shortage of fuel deposits contributed a lot in referring to alternative power facilities, such as solar stations, wind farms and tidal power systems. However, these are the prerogative of those lands possessing suitable climate conditions and favoring national policy. On the contrary, the other states have many benefits for biofuels production, converting wastes and unnecessary materials into promising energy resources. Some examples testify on how creative and effective new technologies might be.

Germany is a vivid example of how biofuels might invest in national energy balance. For several decades German scientists have been working on biofuel technologies, and some of the concepts alerted governmental attention. To date, economic discussions are engaged in related issues, which are focused on how to make biofuels cheaper.  One of the received results is directed on car fuels production out of agricultural and wood wastes. The released technology features synthetic gasoline made of sawdust and straw, including two major stages: gathering basic material straightforward on farms and timber factories and gasoline production on the plant. Its price is expected to be 0,5 Euro per liter and the first supplies are scheduled on 2012.

Wageningen University and Research Centre in Ukraine is working on the concept of thermal and electrical energy from biomass gathered in Chernobyl restricted zone. It is appropriate to mention that this country still copes with consequences of tragic events of April 26th 1986, when there was a huge explosion on the local nuclear plant. However, biomass is offered to be cultivated on the lands cleared from radioactive effects.  All in all, the idea of any activity in Chernobyl zone is quite unpleasing and it might influence negatively on reputation of Ukrainian businessmen. Many scientists conclude that this area should be a testing ground for scientific experiments and investigations for many decades in future.

In contrast, Ukraine can boast of certain biomass advancement. It is the first country in Eastern Europe to establish a production of mobile industrial facilities that convert organic wastes into fuel pellets. These biofuel complexes, called “Forward”, are embedded on the truck platforms. Forward’s average capacity is about 2 tons per hour. The other advantage of these mobile platforms is their cost, which twice cheaper than foreign equipment – 300 thousand dollars.

During recent decades many countries in Europe opened huge biodiesel plants, using different primary materials. One of them is located in Spanish port Ferrol with a total capacity of 200 thousand tons of biodiesel fuels per year. It produces biodiesel from refined and unrefined vegetable oil, mainly soybean and canola oils. Giant biomass recycling plant was put in commission in Kalundborg city in Denmark. This facility performs several important tasks, which include recycling wheat straw, corn stalks and cobs, sugar bagasse and grass; usage of waste steam in biomass production and manufacturing lignin biofuel. Palm oil and rapeseed oil and animal fats are used in three biofuel plants in Rotterdam, which belong to Neste Oil Corp (Finland).  Their total capacity is 800 thousand tons of biodiesel annually.

Going Green in Small Things

Going Green in Small Things

When we think of going green we typically think of things like adding solar panels to your home’s roof or massive wind farms or building a home out of used tires. However, going green does not have to mean making massive, expensive changes to your lifestyle. You can just do a few little things and make a big impact on the environment. Here are some little things you can change –

  1. Light Bulbs – We all know that the classic light bulb is a huge waste of electricity and heat. Thankfully we have other options today. Even big chain stores carry a variety of eco-friendly lighting choices. LED lights are becoming cheaper every year and use almost no electricity while still providing more than enough light.
  2. Car Maintenance –Keeping your car maintained is an easy way to help the environment. A well maintained car does not give off as much pollution and a car with inflated tires and a clean fuel injector assembly does not use as much gas. Not only are you reducing emissions, but you are also reducing the drain on non-renewable resources and the transportation and processing required to get them to your local gas station.
  3. Insulation –An easy and inexpensive way to make your home more eco-friendly is to replace your insulation. A well-insulated home stays warmer in winter and cooler in summer, reducing your need for utilities to heat and cool your home. It also helps to replace your windows with double paned glass. This double layer of glass means that less cool air will escape in the summer and fewer icy breezes will get in during the winter. You can even have your windows tinted or add dark colored screens to reduce sun exposure and keep your house cooler.
  4. Recycle –This simple idea has been around for a long time but is still something that we need to be reminded to do every once in a while. You should be recycling everything you can. Things like soda cans, glass jars, and plastic jugs can be recycled into new, useful things. Even paper products can be recycled. If your community does not have a recycling program you can form one or find your closest recycling center. Oftentimes your local public school will have a recycling program in place and would be glad for any donations you care to provide.
  5. Shop Smart –Las but not least, learn to shop smart. Try to buy locally as much as you can, reducing the transportation costs and emissions to get the products to the store. Try to find items that are made from recycled materials and thingsthat can be reused instead of thrown away.

All these little steps add up to really help the environment. Remember that you do not have to be rich to be green. Just a few thoughtful changes and a little effort on your part can help us to keep the Earth in shape for the next generation.

Green Walls For Energy Saving

Green Walls for Energy Saving

Edmonton Int. Airport, Edmonton, Alberta

The idea of creating a green wall may not be new, after all people have been growing ivy and other vines on their homes for centuries, but a Canadian company, Green Over Grey has brought the concept to new heights.

With modern techniques and hydroponic planting, the company is able to install huge living walls on the sides of cooperate buildings. These walls include a wide variety of plants and weigh far less than any other planting method like this.

Another advantage to Green Over Grey’ s technique is that the plants are irrigated in a way that not only keeps them alive but is not wasteful. The plants can be designed in a variety of styles and each installation is individualized to the climate and the customer’s needs.

Businesses that use this living wall technology also receive LEED benefits, a decrease of up to 20% in their electricity costs, and benefits to employees such as increased air quality and a reduction in noise pollution.

It is not only businesses that can benefit from these living walls. Individuals can also have living walls, called vertical gardens, installed inside or outside their homes. From bringing life into the house to giving new life to your house, these installations are easy to maintain and stay green year-round.

HIT Solar Cells

Cheaper Manufacturing for HIT Solar Cells

This is a guest post by Mathias Aarre Maehlum of  Energy Informative

Fraunhofer Institute for Surface Engineering and Thin Films IST in Braunschweig, Germany, has been working on making the manufacturing of HIT solar cells cheaper by engineering an improved coating process.

Hetorjunction with Intrinsic Thin layer (HIT) solar cells are currently one of the most promising new technologies in the PV industry. They have consistently shown high performance in laboratory conditions – in some cases up to 23% – significantly higher than the majority solar modules on today`s market.

Fraunhofer IST`s new way of producing HIT solar cells includes hot wires instead of the plasma-CDV process, which allows for cheaper mass production. The plasma-CDV process is dependent on large quantities of silane gas to function. Somewhere of 85-90% is lost through the process and becomes waste, which of course brings costs up.

By using the hot wire method “we can use almost all of the silane gas, so we actually recover 85 to 90 percent of the costly gas. This reduces the overall manufacturing costs of the layers by over 50 percent. The price of the wire that we need for this process is negligible when compared to the price of the silane” states Dr. Lothar Schäfer, department head at Fraunhofer IST.

The generators that power the manufacturing system are also ten times less expensive in terms of energy consumption than those that power the plasma CDV-process.

Even though the technology seems to have significant advantages over convetional ways of producing solar cells, it is still nowhere near being released on the market. It will likely be another three to five years until Fraunhofer IST`s new technology will be used for large-scale manufacturing of solar panels.

For more information on the new technology, check out the official press release.

Green Kids like going green

How to Get Kids Involved in Being Green

In recent years, many of us have shifted into living a greener life. We’ve become more aware of turning off lights when we leave a room, have switched to using reusable grocery bags, and have started sorting trash from recyclables before throwing things out. However if we want to continue to further the green movement we can’t stop there. We have to get our kids involved in living a greener life too; otherwise our efforts will eventually stall out. To help get your kids involved and interested in the green movement, try these tactics:

  1. Make it a challenge. Kids love to compete against other people, so make going green a challenge. See who can collect the most recyclables throughout the week and give everyone a different bin to put their recycling in. Assign different people in the house different green chores, like making sure all the lights are turned off before bedtime or collecting cans around the neighborhood, and keep track of who is the most consistent at accomplishing their tasks. At the end of each week award a prize to who did the best job, like letting them pick the movie to watch on movie night or taking the family to the winner’s favorite restaurant for a meal.
  2. Make it fun. Not all recyclables have to be taken to the recycling bin; instead make craft projects out of old toilet paper and paper towel tubes, or artwork out of scrap paper. Have the kids make papier-mâché robots from the tubes and cereal boxes, or paint pictures over paper that’s been written on. Show them how easy it is to re-purpose recyclable items instead of throwing them away.
  3. Plant a produce garden together. To teach kids the importance of eating locally grown, organic foods, plant a garden together. They’ll love spending time outside working in the dirt alongside you, and how often do we really encourage them to get their hands dirty? They’ll learn about gardening and biology in the process, and they’ll be proud when they harvest their produce or herbs.
  4. Talk to them about the importance of going green. Kids are like sponges when it comes to absorbing information, so talk to them regularly about how important it is to our planet to live a green lifestyle. Explain how we’re hurting our planet, how we can help, and why everyone needs to pitch in. They’ll probably end up retaining a lot more information than you think.
  5. Involve them in your green efforts. When you need to take the recycling to the recycling plant, take the kids with you. Have them help you sort through trash and recyclables together. Make a game out of crushing cans. Show them how they can pick up trash around the neighborhood to help keep everything clean and beautiful.

By actively living a green lifestyle and encouraging our children to do the same we can make a lasting difference in the preservation of our planet. Don’t assume that kids are too young to be involved; instead teach them from early on how they can make a difference. It’s through the generations to come that we can help clean up and preserve our planet, and every little bit helps.

Tidal Power Then and Now

A while back I wrote a post on Tidal Barrages (https://lifekills.wordpress.com/2009/02/13/tidal-power-barrages-and-ebb-generation/). Here is another way to generate energy from tides.

Probably, everybody is aware of possibilities of energy production in case of extinction and depletion of fuel deposits.  The solution is found in renewable energy due to multiple opportunities provided by natural and environmental conditions. Tidal energy is the one secured by both cosmic gravitation of the Sun and the Moon, and oceanic spaces, of course. However, not all the regions on Earth can boast of favorable and promising tidal indicators. That is why it is better to feature on France and the English Channel as an area where tidal energy generation was organized for the first time and where the most powerful tidal station is going to be constructed this year.

It is interesting to know that the first registries of tidal energy usage are dated back to the 10th -11th centuries. There were lots of windmills and sawmills in England and France, which used tidal energy in industrial purposes. However, only one of these two states might be marked with erection of the first tidal energy system in the world. It was Rance Tidal Power Station, constructed on the estuary of Rance River (Brittany Peninsula) in 1966. Its capacity is pretty astonishing – 240 MW produced by 24 tidal generators, – which is preconditioned by comparatively high tides reaching 13,5 meters. The significance of Rance station is still of high value even nowadays, contributing 0,012% to energy demand in the country. Most of the power generated by the station is used during peak seasons (544 million kWh per year in total). However, high prices obstruct the enlargement of tidal energy industry. Speaking of energy production in France, nuclear power production keeps the lowest cost. In this case, the renovation of the Rance station is getting more appropriate and promising.

On the contrary, in 2012 Frenchmen might see the most powerful tidal project actualized. In particular, it is associated with the station near the coast of Paimpol-Bréhat in Brittany. The project was assigned to Irish company OpenHydro Group Ltd. and French company EDF, which already accomplished some magnificent and profitable projects on tidal energy in North America and the United Kingdom. Paimpol-Bréhat power station was designed in 2004 (estimated cost was 55 million dollars) and in 2008 the construction was started.

The basis of new tidal station is comprised of four large turbines with a weight of nearly 850 tones each. They are going to be established near the coast, attached to an anchor on the depth of 115 meters. The diameter of each turbine is 21, 5 meters. It is appropriate to note that tidal turbines have certain advantages in opposite to wind and solar cells, including invisibility under the water, quiet operation and less impact on environment. And, besides, a new station can provide energy for more than 4 thousand houses in the region of Paimpol-Bréhat.

Eco-houses are on their way

 

Construction of environmentally friendly houses is a new trend in modern architecture, which benefits both to art and energy efficiency. Multiple definitions might be provided to enclose main purposes and peculiarities of such housebuilding, but the prime idea is finding a way to live in harmony with nature. To give some details, there are some requirements if to construct an eco-house.

Firstly, it should be made of local materials, which are low-cost in the context of production, processing, transportation methods and letting to apply the house building technology without heavy equipment. In this way, after accomplishment of exploit period the materials used might be utilized just on the site. Small financial expenses facilitate the availability of ecohouses to the majority of people. Secondly, energy efficiency systems contribute to living in a harmony with surrounding environment. In particular, they include solar panels embedded on the roofs, small wind turbines, geothermal power generators, etc. Thirdly, residence in ecohouses stipulates the engagement in essential biointensive technologies usage, which emphasizes processing and recycling of organic wastes and improvement of soil fertility. In the majority of cases it is associated with agricultural activity featuring cultivation of compost plants and organic farming. Ecohouse must ensure the accumulation of environmental resource area, on which it is built.

There are several magnificent examples of ecohouse building, which alert an attention by brave ideas and original construction. One of the recent advancements is observed in Peking, where this architect trend is performed not by single house, but the whole apartment complex. To be more précised, Linked Hybrid (the project name) is based on the geothermal power generators: the heating is provided by 660 geothermal springs located on the 100-meter depth. The entire complex consists of 8 linked buildings, maintaining 750 apartments, cinema, school, hotel, sport facilities and department stores. The total area is 220 thousand square meters. The other green technologies, embedded in Linked Hybrid Project, are recirculation of water and greenery on roofs. Hence, ecohouse building involves not only separate suburban houses, but the apartment complexes in the hearts of urban living nowadays.

It is also appropriate to name the best example of ecohouse construction in the world. Lumenhaus in the United States is a true reflection of scientific breakthrough and exquisite architect style. The achievements of Lumanhaus include low cost, simplicity and, of course, energy efficiency. The energy support of the building is ensured by 45 solar panels, implemented on the rooftop and along the perimeter (the total area is 72 square meters). The architect merits were estimated from the point of ergonomics: the house is opened and spacious enough to change a room configuration in correspondence to owner’s preference.

Notwithstanding architect art engagement, ecohouses appear to be systems with positive ecological resource. Therefore, their main value is in establishing a compromise with nature and further improvement of human-environment relationship.

The Lorax by Dr. Seuss


At the far end of town

where the Grickle-grass grows
and the wind smells slow-and-sour when it blows
and no birds ever sing excepting old crows…
is the Street of the Lifted Lorax.
And deep in the Grickle-grass, some people say,
if you look deep enough you can still see, today,
where the Lorax once stood
just as long as it could
before somebody lifted the Lorax away.
What was the Lorax?
And why was it there?
And why was it lifted and taken somewhere
from the far end of town where the Grickle-grass grows?
The old Once-ler still lives here.
Ask him. He knows.
You won’t see the Once-ler.
Don’t knock at his door.
He stays in his Lerkim on top of his store.
He lurks in his Lerkim, cold under the roof,
where he makes his own clothes
out of miff-muffered moof.
And on special dank midnights in August,
he peeks
out of the shutters
and sometimes he speaks
and tells how the Lorax was lifted away.
He’ll tell you, perhaps…
if you’re willing to pay.

On the end of a rope
he lets down a tin pail
and you have to toss in fifteen cents
and a nail
and the shell of a great-great-great-
grandfather snail.
Then he pulls up the pail,
makes a most careful count
to see if you’ve paid him
the proper amount.
Then he hides what you paid him
away in his Snuvv,
his secret strange hole
in his gruvvulous glove.
Then he grunts, “I will call you by Whisper-ma-Phone,
for the secrets I tell you are for your ears alone.”
SLUPP!
Down slupps the Whisper-ma-Phone to your ear
and the old Once-ler’s whispers are not very clear,
since they have to come down
through a snergelly hose,
and he sounds
as if he had
smallish bees up his nose.
“Now I’ll tell you,”he says, with his teeth sounding gray,
“how the Lorax got lifted and taken away…
It all started way back…
such a long, long time back…
Way back in the days when the grass was still green
and the pond was still wet
and the clouds were still clean,
and the song of the Swomee-Swans rang out in space…
one morning, I came to this glorious place.
And I first saw the trees!
The Truffula Trees!
The bright-colored tufts of the Truffula Trees!
Mile after mile in the fresh morning breeze.
And, under the trees, I saw Brown Bar-ba-loots
frisking about in their Bar-ba-loot suits
as they played in the shade and ate Truffula fruits.
From the rippulous pond
came the comfortable sound
of the Humming-Fish humming
while splashing around.


But those trees! Those trees!
Those Truffula Trees!
All my life I’d been searching
for trees such as these.
The touch of their tufts
was much softer than silk.
And they had the sweet smell
of fresh butterfly milk.
I felt a great leaping
of joy in my heart.
I knew just what I’d do!
I unloaded my cart.
In no time at all, I had built a small shop.
Then I chopped down a Truffula Tree with one chop.
And with great skillful skill and with great speedy speed,
I took the soft tuft, and I knitted a Thneed!
The instant I’d finished, I heard a ga-Zump!
I looked.
I saw something pop out of the stump
of the tree I’d chopped down. It was sort of a man.
Describe him?… That’s hard. I don’t know if I can.



He was shortish. And oldish.
And brownish. And mossy.
And he spoke with a voice
that was sharpish and bossy.
“Mister!” he said with a sawdusty sneeze,
“I am the Lorax. I speak for the trees.
I speak for the trees, for the trees have no tongues.
And I’m asking you, sir, at the top if my lungs”-
he was very upset as he shouted and puffed-
“What’s that THING you’ve made out of my Truffula tuft?”
“Look, Lorax,” I said.”There’s no cause for alarm.
I chopped just one tree. I am doing no harm.
I’m being quite useful. This thing is a Thneed.
A Thneed’s a Fine-Something-That-All-People-Need!
It’s a shirt. It’s a sock. It’s a glove, It’s a hat.
But it has other uses. Yes, far beyond that.
You can use it for carpets. For pillows! For sheets!
Or curtains! Or covers for bicycle seats!”
The Lorax said,
“Sir! You are crazy with greed.
There is no one on earth
who would buy that fool Thneed!”

But the very next minute I proved he was wrong.
For, just at that minute, a chap came along,
and he thought the Thneed I had knitted was great.
He happily bought it for three ninety-eight
I laughed at the Lorax, “You poor stupid guy!
You never can tell what some people will buy.”
“I repeat,” cried the Lorax,
“I speak for the trees!”
“I’m busy,” I told him.
“Shut up, if you please.”
I rushed ‘cross the room, and in no time at all,
built a radio-phone. I put in a quick call.
I called all my brothers and uncles and aunts
and I said, “Listen here! Here’s a wonderful chance
for the whole Once-ler Family to get mighty rich!
Get over here fast! Take the road to North Nitch.
Turn left at Weehawken. Sharp right at South Stitch.”
And, in no time at all,
in the factory I built,
the whole Once-ler Family
was working full tilt.
We were all knitting Thneeds
just as busy as bees,
to the sound of the chopping
of Truffula Trees.

Then…
Oh! Baby! Oh!
How my business did grow!
Now, chopping one tree
at a time
was too slow.
So I quickly invented my Super-Axe-Hacker
which whacked off four Truffula Trees at one smacker.
We were making Thneeds
four times as fast as before!
And that Lorax?…
He didn’t show up any more.
But the next week
he knocked
on my new office door.
He snapped, “I am the Lorax who speaks for the trees
which you seem to be chopping as fast as you please.
But I’m also in charge of the Brown Bar-ba-loots
who played in the shade in their Bar-ba-loot suits
and happily lived, eating Truffula Fruits.
“NOW… thanks to your hacking my trees to the ground,
there’s not enought Truffula Fruit to go ’round.
And my poor Bar-ba-loots are all getting the crummies
because they have gas, and no food, in their tummies!
“They loved living here. But I can’t let them stay.
They’ll have to find food. And I hope that they may.
Good luck, boys,” he cried. And he sent them away.
I, the old Once-ler, felt sad
as I watched them all go.
BUT…
business is business!
And business must grow
regardless of crummies in tummies, you know.

I meant no harm. I most truly did not.
But I had to grow bigger.So bigger I got.
I biggered my factory. I biggered my roads.
I biggered my wagons. I biggered the loads
of the Thneeds I shipped out. I was shipping them forth
to the South! To the East! To the West! To the North!
I went right on biggering… selling more Thneeds.
And I biggered my money, which everyone needs.
Then again he came back! I was fixing some pipes
when that old-nuisance Lorax came back with more gripes.
“I am the Lorax,” he coughed and he whiffed.
He sneezed and he snuffled. He snarggled. He sniffed.
“Once-ler!” he cried with a cruffulous croak.
“Once-ler! You’re making such smogulous smoke!
My poor Swomee-Swans… why, they can’t sing a note!
No one can sing who has smog in his throat.
“And so,” said the Lorax,
“-please pardon my cough-
they cannot live here.
So I’m sending them off.
“Where will they go?…
I don’t hopefully know.
They may have to fly for a month… or a year…
To escape from the smog you’ve smogged up around here.

“What’s more,” snapped the Lorax. (His dander was up.)
“Let me say a few words about Gluppity-Glupp.
Your machine chugs on, day and night without stop
making Gluppity-Glupp. Also Schloppity-Schlopp.
And what do you do with this leftover goo?…
I’ll show you. You dirty old Once-ler man, you!
“You’re glumping the pond where the Humming-Fish hummed!
No more can they hum, for their gills are all gummed.
So I’m sending them off. Oh, their future is dreary.
They’ll walk on their fins and get woefully weary
in search of some water that isn’t so smeary.”
And then I got mad.
I got terribly mad.
I yelled at the Lorax, “Now listen here, Dad!
All you do is yap-yap and say, ‘Bad! Bad! Bad! Bad!’
Well, I have my rights, sir, and I’m telling you
I intend to go on doing just what I do!
And, for your information, you Lorax, I’m figgering
On biggering
and BIGGERING
andBIGGERING
and BIGGERING,
turning MORE Truffula Trees into Thneeds
which everyone, EVERYONE, EVERYONE needs!”
And at that very moment, we heard a loud whack!
From outside in the fields came a sickening smack
of an axe on a tree. Then we heard the tree fall.
The very last Truffula Tree of them all!

No more trees. No more Thneeds. No more work to be done.
So, in no time, my uncles and aunts, every one,
all waved me good-bye. They jumped into my cars
and drove away under the smoke-smuggered stars.
Now all that was left ‘neath the bad smelling-sky
was my big empty factory…
the Lorax…
and I.
The Lorax said nothing. Just gave me a glance…
just gave me a very sad, sad backward glance…
as he lifted himself by the seat of his pants.
And I’ll never forget the grim look on his face
when he heisted himself and took leave of this place,
through a hole in the smog, without leaving a trace.
And all that the Lorax left here in this mess
was a small pile of rocks, with one word…
“UNLESS.”
Whatever that meant, well, I just couldn’t guess.

That was long, long ago.
But each day since that day
I’ve sat here and worried
and worried away.
Through the years, while my buildings
have fallen apart,
I’ve worried about it
with all of my heart.
“But now,” says the Once-ler,
“Now that you’re here,
the word of the Lorax seems perfectly clear.
UNLESS someone like you
cares a whole awful lot,
nothing is going to get better.
It’s not.
“SO…
Catch!” calls the Once-ler.
He lets something fall.
“It’s a Truffula Seed.
It’s the last one of all!
You’re in charge of the last of the Truffula Seeds.
And Truffula Trees are what everyone needs.
Plant a new Truffula.Treat it with care.
Give it clean water. And feed it fresh air.
Grow a forest. Protect it from axes that hack.
Then the Lorax
and all of his friends
may come back.”

Khakassky wetlands Siberia

Once again about wetlands

Every February the “Khakassky” Reserve tells about wetlands – the unusual places for common people. Actually, in the word “wetland” our beautiful Khakass lakes and steppe rivers are implied. The wetlands are the habitats of natatorial and semi-aquatic birds. However, except them, a large quantity of other kinds of plants and animals lives and breeds in these territories. Wetlands concentrate various kinds of life, both water and land.

Traditionally by February 2, the “Khakassky” Reserve opens a series of actions devoted to the World Wetlands Day. This year we have prepared an Internet quiz, intellectual game and have opened a small photo-exhibition dedicated to the wetlands of the world.

The Internet quiz, devoted to this important ecological day, was held from the 19th to 27th of January. It was the first time, when the “Khakassky” Reserve decided to involve Internet audience in such competition, and this attempt appeared to be successful. During the week, more than 150 letters from participants of our quiz had been arriving to the reserve’s e-mail. People from different regions of Russia took part in the competition. Except local participants, the quiz attracted the attention of people from such republics as Buryatia and Tyva, the Moscow, Smolensk, Volgograd, Tula, Voronezh, Irkutsk, Novosibirsk, Kemerovo, Pskov oblasts, the Altai and Krasnoyarsk and some others regions. The age of participants was from 10 to 52 years. They were schoolboys, students, housewives and so on. 49 participants gave the right answers. All of them were given the memorable prizes. Six winners of the Internet quiz became participants of the intellectual game, which was held in a conference hall of the “Khakassky” Reserve. On February 2, in the World Wetlands Day, they fought the intellectual duel with a command of students from the Khakass State University, where they won one more victory.

The photo-exhibition, which was opened also on February 2, acquaints visitors with various wetlands of the whole world. We have tried to present all continents. Visitors of photo-exhibition can get acquainted with landscapes of the London Wetland Centre – the reserve located on 40 hectares of marshland in the center of capital of Great Britain, London. The Kota Kinabalu Wetland Centre is located in Malaysia, Borneo and covers 24 hectares mangrove, and Lake Naivasha – fresh-water lake in Kenya in semidroughty area of the East African zone. The wetlands of Southeast Asia, Canada, Finland, Switzerland open their beauties before our visitors.

The World Wetlands Day is especially notable in a calendar of ecological dates of the “Khakassky” Reserve. Various kinds of world wetlands are present in the Republic of Khakasia. Khakasia is rich of high-mountainous lakes, bogs, marshes and river gulfs, fresh and salty lakes. Many kinds of grounds are protected by the “Khakassky” Reserve. The most well-known protected grounds are the lakesides of Bele and Shira lakes, and also such reserved lakes as Itkul and Ulug-Kol. In order to keep these known and unknown natural sites safe and not to let them disappear from the interconnected and interdependent wetlands system, the “Khakassky” Reserve will continue the educational and nature protection work.

How Many Trees Will the Kindle Save?

The festive season during late 2011 could have been called the gadget season as tablet computer owners increased from 10% to 19% of the US population from mid December 2011 to early January 2012. The same figures applied to owners of eBook readers – Amazon don’t and won’t say exactly how many Kindles they sold. Some people bought both. An incredible 29% of people (up from 18%) now own at least a tablet or an eBook reader – that’s almost one in three of the entire population according to the figures from pewinternet.org.

So how many trees are being saved by Americans reading books on either their dedicated eBook reader or via software on their tablet computer?

How many trees to make a book?

There isn’t an easy mathematical equation to definitely show how many trees are needed to make a book because there are too many unknown figures in the equation. Trees vary in size both in height and width, even within the same species. Books vary in size in both size and length – number of pages, making it impossible to give a simple answer to the question, but some experts have taken averages into account to show some results.

How far does one cord go?

You may not have heard of the measurement cord, but one cord of dense hardwood, air-dried, produces 942 copies of a 100 page hardcover book. TAPPI, who provided the figures, based their results on roughly 15 trees with a 10 inch diameter to make up one cord. If you click on the link you will find out more about the tree to book making process.

Working backwards, that means each tree makes around 60 100-page books, but as the average novel appears to contain around 300 pages, each tree makes about 20 books. If you have been reading the Stieg Larsson trilogy concerning his heroine Lisbeth Salander, you will know that each tree will provide just over 3 sets of the trilogy. 65 million of you have bought the set so let us hope more now have it in the shape of an eBook file rather than downing a full forest to provide for the book’s paper.

The cost of maintaining a Kindle

The cost of books bought – mostly as paperbacks from your grocery store – is close to the cost of downloading an eBook from your favorite online store, be that for your iPad, your Kindle, your Nook or Sony reader. However, there has been a surge in books available in eBook format at anything from 99 cents to less than three dollars. Your local Wal-Mart won’t sell you a paperback at less than 4 dollars.

There has been a general encouragement to read more books because they are priced so cheaply in the electronic version. As eBook readers mostly store at least 1,000 books, it will be easier to take enough books on vacation without affecting the ever dwindling baggage allowances. Therefore, the eBook reader will save you money over the traditional paperback purchase in weight allowance alone. More importantly, your carryon baggage can be considerably lighter as each paperback weighs more than an eBook reader and most avid readers carry at least two in fear of having nothing to read.

The lowering of weight on the airplane per passenger will reduce the weight of the airplane which means they will gain more miles to the gallon of air fuel. You should not wait around to collect your cheaper ticker based on this assumption.

Your Kindle or other eBook reader still needs to be charged. That costs electricity even if you charge from your laptop computer. It may only be a trickle, but there are several million more trickles going out through the system since the festive season. However, this needs to be balanced against the costs of making a paperback which uses more energy than charging an eBook and the time spent online downloading a new book or two.

Who wins?

Even if you balance up the cost of making the eBook reader and the cost of charging the gadget, a lot less energy is being used compared to the process of making paperbacks. You will still buy paperbacks, but only if your choice of downloading provider doesn’t have the book in its store.
