Do you realize when you’re “Interacting” with an Introvert?

Local introvert Dennis Brewer reported:

Only 20 Minutes Until Introverted Man Gets To Leave Party

SAN MATEO, CA—Having already spent a considerable amount of time quietly examining items around the apartment and standing on the periphery of others’ discussions.

He walked away under the pretense that he needed to refill his cup of beer, local introvert Dennis Brewer reported today that there are only 20 minutes left before he gets to leave an acquaintance’s house party.

“I told myself I’d stay here until 8:30, and I already killed about 15 minutes avoiding conversation by circling repeatedly around the table of hors d’oeuvres to appear occupied, and another cumulative half hour pretending to text friends, so I just need to make it a few more minutes,”

The tense man told reporters while sifting through a pile of coats on the host’s bed as if he was having trouble locating his jacket, an activity he planned to perform for the next 10 minutes or until someone else entered the room.

“If I walk back and forth between the conversations in the kitchen and the living room for a little while and go back to the bathroom one more time, then I’ll have been here long enough to tell the host that I have some work to finish up before bed and that I should probably get going...

Then it’s just a matter of slipping on my shoes and waiting to tie them until I get out the door so that not too many people see me leaving and ask why I’m heading out so soon.”

At press time, sources reported that Brewer’s plans for withdrawal were dangerously imperiled by a partygoer’s insistence that the whole group hit up a nearby bar.

How to interact with the introverted…

If billboards were that useful: Clean water dripping from them in Peru

Lima, capital of Peru, at the edge of the Atacama Desert, is one of the driest places on earth:  It receives almost no rainfall.
About 700,000 people have no access to clean water for drinking or bathing.
Another 600,000 of the city’s 7.5 million residents rely on cisterns for their water, which must be filled by pumps or by hand and cleaned regularly.
April 25, 2013

Lima’s Pacific Coast location experiences humidity of more than 90% on summer days, from December to February.

So engineers from Peru’s University of Engineering and Technology (UTEC) have devised a way to turn that humid air into usable water.

Last December, they erected a billboard in the Bujama District of Lima that by early March had produced 9450 liters (about 2500 gallons) of water.

The idea came about because UTEC was facing a slump in enrollment as the new semester approached; the engineering department wanted a way to attract more engineering students to the university. They went to Peruvian ad agency Mayo Publicidad, and the partnership of engineers and marketers crafted an advertisement that would provide a very visible demonstration of the university’s engineering projects.

And the water-collecting billboard was born.

Electricity from the city’s power lines runs the 5 condensers inside the billboard. Like the condenser in your home air conditioner, the ones in the UTEC billboard are cooler than the air outside.

When air contacts the cooled surfaces of the condensers, the air also cools, and the water vapor in the air condenses into liquid water.

After reverse-osmosis purification, the water flows down into a 20-liter storage tank at the base of the billboard. The billboard generates about 96 liters of water each day, and a simple faucet gives local residents access to the water. UTEC has not yet announced whether the water will be available for free, but the billboard reportedly cost only about $1200 to install.

This is not the first attempt to pull clean water out of thin air.

In 2011, French company Eole installed a wind turbine in Abu Dhabi, which the company claims generates more than 1400 liters of water each day.

The WMS1000 is 24 meters (about 78 feet) tall, and its 13-meter rotor turns at up to 100 rpm to run a 30-kilowatt generator. This in turn powers a cooling compressor inside the turbine. An intake pulls air into the compressor, and moisture condenses out as the air cools. The water runs down into a purification and storage tank at the base of the turbine.

The turbine needs winds of at least 15 mph to generate enough power for the compressor.

In a desert climate with an average temperate of 95 degrees Fahrenheit and average relative humidity of about 30 percent, the WMS1000 generates about 350 liters of water a day. In humid coastal climates, production increases to about 1200 liters a day. Adding a solar power unit to the turbine could increase output by a few hundred liters more.

Eole designed the turbine for remote communities of fewer than 5000 people, but when it launched the WMS1000 commercially, in 2012, the price tag for a single turbine was about $660,000, well beyond the budget of most small communities in developing countries. (which defeat the purpose?)

Back in Lima, the UTEC engineering department and Mayo Publicidad may have found a way to offset the cost barrier: advertising.

Since the billboard’s installation, UTEC reports a 28% increase in enrollment.

Results like that may attract the attention of private companies looking for new ways to advertise. The city of Lima and other urban areas, such as Cairo, Egypt, suffer the same lack of potable water as remote villages, and an advertising-funded solution that taps into an existing electrical infrastructure may work well there.

UTEC has not yet announced plans to install more billboards in Lima or to make the technology commercially available elsewhere, but the project has started new discussions about how to provide access to clean water.

Worldwide, the World Health Organization estimates, about a billion people lack access to safe drinking water.

Lack of clean water is a leading cause of cholera and other diseases that cause diarrhea.

Perhaps UTEC’s idea can make the situation a little better, one sign at a time.

Running Out of Garbage? Want to ship some more to Norway?

OSLO, Capital of Norway, is a city that imports garbage. Some comes from England, Ireland and from neighboring Sweden. It even has designs on the American market.
 posted this April 29, 2013 on nyt

A trash incinerator. Roughly half of Oslo and most of its schools are heated by burning garbage.

“I’d like to take some from the United States,” said Pal Mikkelsen, in his office at a huge plant on the edge of town that turns garbage into heat and electricity. “Sea transport is cheap.”

Oslo, a recycling-friendly place where roughly half the city and most of its schools are heated by burning garbage — household trash, industrial waste, even toxic and dangerous waste from hospitals and drug arrests — has a problem: it has literally run out of garbage to burn.

The problem is not unique to Oslo, a city of 1.4 million people.

Across Northern Europe, where the practice of burning garbage to generate heat and electricity has exploded in recent decades, demand for trash far outstrips supply.

Northern Europe has a huge generating capacity,” said Mr. Mikkelsen, 50, a mechanical engineer who for the last year has been the managing director of Oslo’s waste-to-energy agency.

Yet the fastidious population of Northern Europe produces only about 150 million tons of waste a year, he said, far too little to supply incinerating plants that can handle more than 700 million tons. “And the Swedes continue to build” more plants, he said, a look of exasperation on his face, “as do Austria and Germany.”

Stockholm, to the east, has become such a competitor that it has even managed to persuade some Norwegian municipalities to deliver their waste there.

By ship and by truck, countless tons of garbage make their way from regions that have an excess to others that have the capacity to burn it and produce energy.

There’s a European waste market — it’s a commodity,” said Hege Rooth Olbergsveen, the senior adviser to Oslo’s waste recovery program. “It’s a growing market.”

Most people approve of the idea. “Yes, absolutely,” said Terje Worren, 36, a software consultant, who admitted to heating his house with oil and his water with electricity. “It utilizes waste in a good away.”

The English like it, too, though they are not big players in the garbage-for-energy industry. The Yorkshire-based company that handles garbage collection for cities like Leeds, in the north of England, now ships as much as 1,000 tons a month of garbage — or, since the bad stuff has been sorted out, “refuse-derived fuel” — to countries in Northern Europe, including Norway, according to Donna Cox, a Leeds city spokeswoman.

A British tax on landfill makes it cheaper to send it to places like Oslo. “It helps us in reducing the escalating costs of the landfill tax,” Ms. Cox wrote in an e-mail.

For some, it might seem bizarre that Oslo would resort to importing garbage to produce energy.

Norway ranks among the world’s 10 largest exporters of oil and gas, and has abundant coal reserves and a network of more than 1,100 hydroelectric plants in its water-rich mountains. Yet Mr. Mikkelsen said garbage burning was “a game of renewable energy, to reduce the use of fossil fuels.”

Of course, other areas of Europe are producing abundant amounts of garbage, including southern Italy, where cities like Naples paid towns in Germany and the Netherlands to accept garbage, helping to defuse a Neapolitan garbage crisis.

Yet though Oslo considered the Italian garbage, it preferred to stick with what it said was the cleaner and safer English waste. “It’s a sensitive question,” Mr. Mikkelsen said.

Garbage may be, well, garbage in some parts of the world, but in Oslo it is very high-tech.

Households separate their garbage, putting food waste in green plastic bags, plastics in blue bags and glass elsewhere. The bags are handed out free at groceries and other stores.

The larger of Mr. Mikkelsen’s two waste-to-energy plants uses computerized sensors to separate the color-coded garbage bags that race across conveyor belts and into incinerators.

The building’s curved exterior, with lighting that is visible from a long distance to motorists driving by, competes architecturally with Oslo’s striking new opera house.

Still, not everybody is comfortable with this garbage addiction. “From an environmental point of view, it’s a huge problem,” said Lars Haltbrekken, the chairman of Norway’s oldest environmental group, an affiliate of the Friends of the Earth. “There is pressure to produce more and more waste, as long as there is this overcapacity.”

In a hierarchy of environmental goals, Mr. Haltbrekken said, producing less garbage should take first place, while generating energy from garbage should be at the bottom. “The problem is that our lowest priority conflicts with our highest one,” he said.

“So now we import waste from Leeds and other places, and we also had discussions with Naples,” he added. “We said, ‘O.K., so we’re helping the Neapolitans,’ but that’s not a long-term strategy.”

Maybe not, city planners say, but for now it is a necessity. “Recycling and energy recovery have to go hand in hand,” said Ms. Rooth Olbergsveen, of the city’s waste recovery agency. Recycling has made strides, she said, and the separation of organic garbage, like food waste, has begun enabling Oslo to produce biogas, which is now powering some buses in downtown Oslo.

Mr. Haltbrekken acknowledged that he does not benefit from garbage-generated energy. His home near the center of town, built about 1890, is heated by burning wood pellets, and his water is heated electrically. In general, he said, Friends of the Earth supports the city’s environmental goals.

Yet he added, “In the short-term, it’s better to burn the garbage in Oslo than to leave it in Leeds or Bristol.”

But “in the long term,” he said, “no.”

A version of this article appeared in print on April 30, 2013, on page A9 of the New York edition with the headline: A City That Turns Garbage Into Energy Copes With a Shortage.

Sweden Out of Garbage

Imagine a world where pollution is a non-issue, cities are pristine, healthy environments to live in, and little to no entanglements from discarded trash injures wildlife or clogs the oceans.

In Sweden, this is almost a reality, yet it’s causing a paradoxical predicament for the recycle-happy country that relies on waste to heat and provide electricity to hundreds of thousands of homes.

Sweden Runs Out of Garbage

Trash piled 9 yards high is converted to heat and electricity at a waste-to-energy incinerator in Oslo.

The Scandinavian nation of more than 9.5 million citizens has run out of garbage; while this is a positive – almost enviable – predicament for a country to be facing, Sweden now has to search for rubbish outside of its borders to generate its waste-to-energy incineration program.

It’s namely Norway officials who are now shipping in 80,000 tons of refuse annually to fuel the country with outside waste.

The population’s remarkable pertinacious recycling habits are inspiration for other garbage-bloated countries where the idea of empty landfills is scarce. In fact, only 4% of all waste in Sweden is land-filled, a big win for the future of sustainable living.

By using its 2 million tons of waste as energy and scrapping for more outside of its borders, this country is shown in international comparisons to be the global leader in recovering energy in waste. Go Sweden.

Public Radio International has the whole story.

This (albeit short-term) solution is even highly beneficial for the Scandinavian country; Norway pays Sweden to take its excess waste, Sweden burns it for heat and electricity, and the ashes remaining from the incineration process, filled with highly polluting dioxins, are returned back to Norway and land filled.

Catarina Ostland, senior advisor for the Swedish Environmental Protection Agency, suggests that Norway may not be the perfect partner for the trash import-export scheme, however. “I hope that instead we will get the waste from Italy or from Romania or Bulgaria, or the Baltic countries because they landfill a lot in these countries” she tells PRI. “They don’t have any incineration plants or recycling plants, so they need to find a solution for their waste”.

There’s definitely something to be said about being ‘green’. Regardless of its sourcing, hopefully Sweden’s impeccable job of reducing its carbon footprint may serve as an example to other areas of the world that have more than enough trash to utilize and put to sustainable use.
