What Exactly Is "Clean Coal" Technology?

  • Oct. 16th, 2008 at 7:40 AM

As a solution to our future energy needs, both Presidential candidates have endorsed "clean coal" technology. It sounds good, but what exactly is it? Is it clean compared to other types of energy production, or is it just cleaner than current coal-burning technology? As a friend pointed out last night, no matter how clean the coal burning facility is, the extraction of coal will remain a very dirty business. If it were up to me, I'd build windmills and solar energy farms everywhere, because in my mind, coal is a 19th century energy source. Coal powered the industrial revolution, the stately dreadnoughts of the Royal Navy, and the massive urban expansion of the early 20th century, but is it still viable today? We still get a shockingly high percentage of our electricity from coal-fired power plants, I think in the DC area it's around 50%. We obviously can't abandon it as an energy source anytime soon. Maybe the best thing to do is to apply this clean coal technology to our existing coal powerplants, but not to build any new ones. I dunno.

Electronics Recycling at Best Buy Expanded

  • Jun. 9th, 2008 at 6:13 PM
I may have been the very first person to recycle a computer at the Best Buy in Columbia Heights, in accordance with their new electronics-recycling policy. In addition to recycling batteries and cellphones, they now take just about anything short of a large-screen TV. 
When my wife's old computer died, I took out the battery and placed it in their battery recycling bin, by the main entrance. To protect our privacy, I removed the hard drive, smashed it up a bit, and discarded it. We brought the laptop itself in to Best Buy on Saturday, explained that we heard about their recycling pilot program on the news, and at first they seemed confused. We were directed to the Geek Squad counter, where we had to wait awhile as they had a couple of unhappy customers in front of us. Finally, they took the thing, but asked us to leave our name and address for some reason. They were a little confused along the way, but ultimately did accept the computer for recycling, so I'll give them a thumbs up for that. 

J's Computer Died

  • May. 9th, 2008 at 6:55 PM

My wife's laptop computer died yesterday, after only a couple of years of service. It wasn't a complete surprise, as it had been exhibiting some strange behavior lately, and the speakers never worked, but J was pretty upset about it. The annoying thing is that, this being America, the obvious solution is to buy a new one instead of having the old one fixed.

She brought the dead laptop in to Best Buy, and had their Geek Squad look at it. They were not super helpful, and didn't make much of an effort to fix it before referring her to the manufacturer, Dell. Dell made her wait on hold for an hour, she was transferred around to several different people, and ended up talking with another unhelpful person. It was no longer under warranty, of course. She was told she'd have to order a part or parts, which cost over $100, then take it all back to the Geek Squad and have them install the parts, for more $$$. Then, at best she'd have  the same old, slow computer as before, where for $650 she could have a far superior new laptop, with working speakers and a better screen. We really need to do something in our society to fix and reuse old things rather than have all market and other forces point to the usual "buy a new one" solution. At least we can properly recycle the old one.    

Coincidentally, a few weeks ago I suggested to my wife she buy a USB flash drive, and back up all of her documents and photos on it. She bought a 2GB flash drive, but didn't have a chance to save her documents on it before her computer died. D'oh! Nothing of vital importance was lost, and fortunately most of her photos are on Flickr, but it does highlight the importance of having a backup copy of everything on your hard drive. The hard drive is intact, and her data could probably be retrieved from it, but it likely won't be worth the time or hassle to do so. 

New Recycling Resource in Columbia Heights

  • Apr. 9th, 2008 at 8:15 AM

One of the first things I noticed about the new Best Buy store in Columbia Heights was the electronics recycling kiosk just inside the entrance. There are separate bins for the recycling of printer cartridges, batteries, and small electronics like cellphones, palm pilots and blackberries . There are little bags provided to keep batteries from leaking. Best Buy has a recycling plan in place, and will hopefully expand it to cover larger items like laptops. Kudos to Best Buy for encouraging proper recycling of electronics.

I've already used the recycling bin there. My wife had an old, first-generation digital camera that was ready for the trash, but I figured it would be OK to put it in the small electronics bin at Best Buy. Having watched far too many Simpsons episodes in my lifetime, I couldn't resist taking a couple of photos of my own butt and leaving them on the camera, just in case anybody looks (apologies, Best Buy employees). It's true, my wife will confirm it - she was on the phone at the time and I was trying to get her to laugh. I did one vertical composition, and one horizontal, and did NOT put the results on Flickr or anywhere else. Recycling is fun!!

 Fredericksburg, Virginia is an interesting, historic town, located halfway between Washington and Richmond, but it sure does have a bird control problem! We took a daytrip there on Saturday, and would have enjoyed walking around the pedestrian-friendly downtown area, rich in 19th century architecture, were it not for the guano-encrusted sidewalks (and historic objects!). At first, I thought the brown slime under each and every tree was the result of smooshed berries or some other natural product of tree reproduction or propagation. But eventually, I put two and two together, when I became aware of the vast flocks of small birds roosting in the trees. We were skating along the sidewalks in bird shit!

I'm a diehard environmentalist, but when you're talking about a town that is compact, pedestrian-friendly, located on a rail link to DC, and has been inhabited for hundreds of years - that's a place where humans should live comfortably. We're not talking about houses encroaching on farmland or forest here, so in my opinion, the birds need to go. I'm willing to leave 95% of the land mass as wilderness, while cramming all humans into dense cities and towns, but within those spaces we should be able to control the populations of rats, pigeons, mosquitoes, etc. The Fredericksburg bird in question is probably an invasive species, or one where we've killed off their natural predators, but something is definitely out of balance in Fredericksburg with these birds. The local government needs to bring in falcons or hawks, or borrow a colony of spayed/neutered feral cats from DC where we have plenty to spare. How about fire off a Civil War cannon every hour to scare them off, and to provide a little battlefield reenactment fun? Plastic owls? Cut down all the street trees and replace them with a less bird-friendly species? I'm sure there's something humane that can be done, which would make the city a lot more livable for its residents.

After a nice lunch and lots of shopping at small, independent businesses, we returned to the car, and of course there was bird crap all over the windshield. Our shoes were encrusted, too, and the emergency roll of paper towels we keep in the car sure came in handy. Then, back to DC, whew, where the streets are clean; well, more or less...

Football Team Flags on Cars

  • Oct. 22nd, 2007 at 1:12 PM

 Now that football season is well underway, it's not uncommon to see vehicles, usually SUVs, sporting dual door-mounted flags with the emblem of their favorite team. Around here, you see mostly Redskins flags on vehicles, with a smattering of other teams, the Cowboys, the Ravens, etc.

I just wanted to point out, as an enviro-weenie, that at highway speeds, these flags do create a significant drag penalty. I would guess that top speed would be reduced by a couple of miles per hour, and fuel economy would likewise decline, especially in a headwind. So, if you want to save a few dollars on gas, as well as reduce your carbon footprint, it's best to lay off the football team flags, and slap on a bumper sticker instead.  

Shortsighted Hawaiian Environmentalists!?!

  • Aug. 30th, 2007 at 12:04 AM
As you all know, I like to follow transportation issues, and have been keeping an eye on the Superferry controversy in Hawaii. Apparently, the only way to get from island to island in the archipelago at this point is to fly, or to go by small, private boat. In the decades prior to safe travel by air, ferries and steamships connected the islands to each other, and to the mainland. There was regular service to LA and San Francisco by the numerous vessels of the Matson Line. 

Someone came up with the idea to start an inter-island ferry service, to provide an alternative to costly air travel. The governor and others backed the idea, and the Superferry was constructed. Astonishingly, some residents are opposed to the ferry, claiming it will be harmful to the environment. One one of its first voyages, protesters in kayaks and on surfboards blocked it from entering harbor, and forced it to turn back. 
   
As an environmentalist, I'm embarrassed by the protesters who have brought this utterly sensible operation to a halt. What are they thinking? Surface transportation by ship is vastly more efficient and uses way less fuel per passenger than air travel. On one 350-foot ferry, they can fit almost 900 passengers - it's like traveling by train compared to multiple private automobiles. It's not like tourists aren't going to come to, and travel about the Hawaiian Islands. Not only that, but the ferry is designed to be as "green" as possible. From the company's website:

Hawaii Superferry is committed to serving Hawaii as an environmentally friendly seagoing operator and is mindful of its responsibility to all ocean life and each island’s unique ecosystem. The vessel’s design incorporates the latest in environmentally responsible maritime technology. The ferry’s waterjet propulsion system has no exposed propellers, thus vastly increasing protection for marine mammals such as whales and Hawaiian seals. The ferry will not discharge wastewater or any trash or other solid waste – these will all be carefully disposed of while the ship is docked in Honolulu. The hull features a unique non-toxic, specially slick paint that will keep unwanted aquatic hitchhikers from traveling across Hawaii's waters. Unlike conventional ships, the catamaran design does not require ballast tanks in which invasive species can catch a ride between our Islands.

So what's not to like, from the environmental perspective? I wonder if these protesters are being bankrolled by the airline industry...

More from Ellwood Thompson's Natural Market

  • Jul. 27th, 2007 at 6:48 PM

I received the following comment on my blog entry regarding Ellwood Thompson's, and thought I'd repost it as a standalone entry:
 
Subject: Ellwood Thompsons Natural  Market  

Dear Mr. T.  

Ellwood Thompson's has been overwhelmed with support from Columbia  Heights residents as well as others in DC's other outstanding  communities. Thank you all very much!   An update in our search is that we are currently very interested in the  DC USA development nearing completion on 14th Ave. We encourage any  support that the neighborhood's interested residents can provide??  
We would like to explain our store concept a little clearer since there  have been a lot of comparisons to other Natural Markets in the area.  Ellwood Thompson's is a full-service Natural/Organic Market that does not  sell any products that contain artificial flavors, colors or  preservatives. Our products contain no hydrogenated oils, parabens, high  fructose corn syrup or transfats.   
The store is approximately 15,000 SF and we're stewards of local farming  and merchants (often working directly with the farm). Quality is top  priority and sampling is encouraged. We have a full-service meat case  (free-range varieties) as well as a deli case/hot bar and a health and  beauty section.   I hope this information is helpful in providing a snapshot of what  Ellwood's has to offer Columbia Heights. For additional information,  please visit our soon-to-be redesigned website at 
http://www.ellwoodthompsons.com  

Many thanks,  
Ryan Youngman CEO,
Ellwood Thompson's 

Good to hear from you, Ryan, and will continue to spread the word about your store. DCUSA still has plenty of space I believe, since the Whole Foods deal fell through. If you open up there, you'll do well, and since it is directly on top of a Metro station, and in the middle of a dense residential neighborhood, it will have a minimal carbon footprint. We hope you do open in Columbia Heights!

A Modest Energy Proposal

  • Jul. 25th, 2007 at 6:05 PM

There has been some debate over whether or not to construct new nuclear powerplants in the United States as a way to increase power production without releasing additional greenhouse gases. My first choice, along with most environmentalists, is to build more solar and wind-powered facilities, but that route may not be able to keep up with demand by itself. The main objections to nuclear power are accidents, and the creation and disposal of nuclear waste. I'm opposed to building more nuclear power plants in populated areas as well.

However, the other day, while looking at a map, I had an idea. The Feds are already committed to consolidating all nuclear waste at the Yucca Mountain storage facility in Nevada. If you recall, this was determined to be the safest location in the continental US, the most geologically stable, furthest from population centers, bodies of water, etc. The area has already been used for nuclear weapons testing years ago, and is probably already contaminated. In addition, with the nuclear waste all in one place, it would be easier to guard it from terrorists than in the current 108 locations around the country. The main problem with this plan is that the transportation of nuclear waste to the site from powerplanst around the country would be risky. There could be accidents, terrorism, and who wants trucks carrying nuclear waste driving through their towns and cities? Not me. Oh, and residents of Nevada aren't too happy about the plan, but us coastal megalopolis types can simply look the other way. He he he. If Nevada sends us power, we'll send them water!  

Why not build a series of nuclear power plants near Yucca Mountain? The area has been the whipping boy for nuclear bomb blasts for decades (900 at the Nevada Test Site), and the transportation of nuclear waste from the powerplants to the storage facility wouldn't be an issue. As the new nuclear power plants come on line, we can close down or convert others that are dangerously close to major population centers on the east coast. Eventually half the state of Nevada will give off a healthy green glow. If anything ever goes catastrophically wrong, the contaminated zone could become a Las Vegas playground, done up to resemble the Chernobyl wasteland.

The EPA Under the Bush Administration

  • Jul. 20th, 2007 at 5:58 PM

I had to call the EPA today for work, and when I dialed their toll-free "national service center for environmental publications" at 1-800-490-9198, I heard something both curious and alarming. The automated voice answering system picks up with "Welcome to the EPA service center, operated under contract by Lockheed-Martin."

Does that sound like a conflict of interest, or what?! I would have hoped the EPA was staffed from top to bottom by earnest enviro-nerds, even in the publications department, not by a giant defense contractor and aerospace conglomerate. Apparently, part of the agency mandated with protecting mother Earth has been given over to a corporation specializing in the manufacture of smog-spewing jet aircraft and other eco-unfriendly, if necessary, technologies.

I have nothing personally against Lockheed-Martin, in fact I admire the history of the Maryland-based Martin division, with their tradition of technological innovation and service in WWII, but come on, they're a major manufacturing concern. It just seems fishy to me that part of the EPA's operations would be contracted out to them.

In his blog entry today, Marc Fisher asks "why doesn't DC have a bottle bill?" the same question has often crossed my mind. I would enthusiastically support a DC bottle bill! We have a HUGE problem with litter in Columbia Heights, and a modest 5 or 10 cent refundable deposit on all plastic and glass bottles would do wonders for the cleanliness of the streets. We have empty beer bottles in the tree boxes, water bottles along recreational trails, flattened soda cans in the street, and broken glass in the bike lanes. Think of all the bottles that are puled from the Anacostia and Potomac Rivers during those annual cleanups. Not only would people be less likely to discard their own empties, they would be inclined to pick up other litter. Back in New York, I recall that homeless people would go around and collect bottles for the deposit everywhere.

When a bottle bill was first proposed for DC twenty years ago, beverage distributors, bottling concerns and liquor and grocery stores lobbied strongly against it, turning what should have been a no-brainer into a racial/class conflict, and they succeeded in blocking any bottle deposit law. The city and attitudes have changed enormously since 1987, and I'm sure such a referendum would pass this time. People of all stripes, black, white and Latino, are much more environmentally aware, and the broken-windows theory has had an impact on street cleanliness and anti-graffiti campaigns. I don't think anybody wants their kids playing on broken glass or exposed to a visual daily bombardment of liquor and beer bottles as part of the landscape. Ward 1 Councilman Graham should float the idea to the other council members and see who else might support him. I'm tired of picking up bottles and cans every day. I must have picked up hundreds in the 11 years I've lived in DC.    

Energy Saving Idea

  • May. 12th, 2007 at 1:02 PM
I've replaced as many incandescent lightbulbs as possible in the house with compact fluorescent ones, but there are some applications where they just aren't suitable. The master bathroom is illuminated by 10 of those large globe lamps, which generate a ton of heat as a byproduct. That's fine in the winter, but in the summer it's very uncomfortable in there. Compact fluorescent bulbs would look silly in the bathroom, so I unscrewed and removed 4 of the 10 regular bulbs and set them aside for future use. There's still plenty of light, but the heat and energy usage will be reduced by 40%. During one of our famous summer heat waves, I may pull additional bulbs. Then, when winter comes around, I can reinstall them, when the heating effect will be welcome. Admittedly, the empty sockets look a little strange, but that's OK by me.

Earth Day 2007

  • Apr. 22nd, 2007 at 5:28 PM
We started off Earth Day appropriately enough, with a group block cleanup. We picked up cigarette butts, beer cans, plastic bags, and other bits of litter, and swept the sidewalks clean. The weather was perfect for it, and it was nice to meet and work alongside some of our neighbors. Afterwards, J and I rewarded ourselves with coffee and breakfast sandwiches at Mayorga, and we read the Sunday Washington Post there. 

Next, we drove over to Tenleytown, where I picked up shelves at the Container Store and J got us salads at Whole Foods. We usually drive there and combine 2-3 errands so as to make the best use of the car, because taking the Metro requires going all the way around and transferring, and taking the H bus while carrying bookshelves isn't practical. 

After lunch and bookshelf installation, we walked down to the National Zoo through Mount Pleasant. It took us about 25-30 minutes to get there, so it's not too far away. It's a little trickier to get into the zoo from the rear entrance as opposed to the Connecticut Avenue side, but we now know the most efficient route. I brought my new camera and took a few shots which will eventually show up on Flickr. The Zoo was jammed with tourists and hundreds of kids. It was overwhelming, but we caught a good look at one of the lions, some turtles, prairie dogs, and tigers before heading back. We have to return to the Zoo before it gets too hot, maybe on a weekday when it presumably isn't as crowded. I think I got a little sunburn on the unprotected top of my head, as there was hardly a cloud in the sky all day.  

Columbia Heights Recycles!

  • Apr. 11th, 2007 at 1:09 PM

Car Bumper in Recycling Bin
Originally uploaded by Mr. T in DC.
We're the greenest neighborhood in the city, clearly the most dedicated to recycling! I spotted this wayward car bumper laying on the sidewalk while walking down Holmead Street NW, near the Giant grocery store. I normally pick up trash and other detritus as I walk around the neighborhood in an attempt to keep it clean, but the bumper was too much for me. I thought I'd call the DC citizen request line 202-727-1000 when I returned home and report the large car part for pickup. I wonder how the bumper got there: was it wreckage left over from a fender-bender, vandalism, kids joy-riding, or amateur roadside body shop gone bad?

The next day, the bumper was gone, and I found it stuffed in a recycling bin labeled for plastic/glass/metal bottles and cans. Fortunately, I had my camera on me and got this shot of the scene. Thank you to whomever the good samaritan was who picked up the bumper and attempted to recycle it! Later on I noticed that the recycling company had rejected the bumper, and stuffed it in a nearby dumpster for conventional disposal. I doubt it was the right kind of plastic anyway.

Which Sweetener is Greenest?

  • Mar. 29th, 2007 at 1:14 PM
I was wondering which of the 4 standard beverage sweeteners is the most environmentally friendly? The contenders are Blue/Equal/aspartame, Pink/Sweet'N Low/saccharin, Yellow/Splenda/sucralose, and plain old sugar. I'm partial to Splenda on grounds of taste, but am happy to switch to whichever one brings about the least damage to the environment when being produced.  One would think that sugar is the most natural, and therefore better, but I'm guessing the processing of it is pretty dirty, and the sugarcane crop itself is an unsustainable monoculture w/pesticides, etc, so who knows? I'm guessing the artificial sweeteners are made in those chemical plants in New Jersey you can see from the Turnpike. 
There are probably smaller companies selling environmentally-friendly sweeteners (I remember a couple from the Green Festival), but one of the major food companies could do well by adopting green-colored packaging for a sweetener that's easier on the planet. I'd use it, even if it didn't taste as good as Splenda.

Quiet Saturday

  • Mar. 24th, 2007 at 10:02 PM
What a dreary day it was, cloudy, cool, drizzly. Poor J ran 10 miles this morning, and didn't feel very good afterwards. We got all our chores done today, so as to keep tomorrow free: went to CVS, drycleaners, did laundry, etc. Speaking of drycleaners, the second one has opened within a couple of blocks, Oxxo Cleaners. They're supposed to be an environmentally friendly operation, so I'll give them a try. 

We had a tasty dinner at Teaism downtown, dodging the growing number of tourists clogging the streets, especially the crowds emerging from the Ringling Brothers Circus at the Verizon Center. We saw a few animal rights protesters on the perimeter, and took a pamphlet from them to read up on the issue. Without knowing too much about circus animals, it would seem that the elephants and other animals are being exploited and certainly could be mistreated. I doubt the elephants have enough room in those trucks and railroad cars they travel from city to city in. When/if we have a kid, we'll probably stay away from circuses and other entertainments that exploit animals, as there are plenty of fun and educational things to see with a child here in DC anyway. I'd have to study the issue a little more before coming to a definitive conclusion, though, so don't quote me on it.

Tonight's Netflix movie was Monsoon Wedding, and it was pretty good. It was surprisingly short for a Bollywood-inspired film (technically a US production, I think), and just ended there just as the wedding ceremony was getting interesting.



Well, I guess the huge salad, avocado, lentil stew, and iced cream yesterday was too much for me. I was up half the night with diarrhea (TMI?), and feel like a zombie today thanks to the lack of sleep, DST change, and dehydration. J and I are meeting S after work for happy hour today, so hopefully I can hang on long enough to have a beer and some non-spicy/greasy food. Not a good start to the week!

One bit of good news today: environmentalist and awareness of global warming appears to be increasing among evangelical Christians. An article in Saturday's Washington Post described how a prominent evangelical organization has embraced environmentalism over the objections of some of the more conservative preachers in the group. What caught my eye in the article was the use of the term "creation care" as a Christian-oriented environmental catch-phrase, which I think is a stroke of pure genius by whoever came up with it. It gives them the cover, I think, to embrace environmentalism without all that messy science and evolution stuff. Obviously not the way I view things, but the more unlikely allies we can gather, the better. Next time I chat with my dad, I'll try out that line.
It started out with me forwarding an article on old Volvos from the NY Times to [info]mr_b_in_la(who is a Volvo aficionado) and ended up with us discussing the demise of the universe. The email chain, in reverse chronological order, is after the jump.

Man vs. Nature, Father vs. Son Style

  • Feb. 16th, 2007 at 6:31 PM

My frustration with the snow continues. Although it had been plowed sufficiently before, the alley was plowed again last night, resulting in a mound of filthy snow and ice shoved into the parking space I had previously shoveled clean. Now, I have to do it all over again. If there's one thing I hate, it's doing the same work repeatedly. I like to do a task thoroughly and efficiently once, and prefer that to be the end of it. No such luck. Hopefully over the weekend we'll have enough melting so that no more plows and salt trucks will plague my area. I'm sure there are plenty of uncleared streets in other parts of the city that could use the attention instead. I'm all for letting nature have its way, and just waiting for the ice to melt.

In other news, my father killed a snake for no apparent reason. I emailed him the other day because we haven't communicated in a month or two and I thought I'd drop him a line about the recent frigid weather. He responded with a description of the weather in Florida, and also mentioned that he found a 3' long snake curled up against his garage. He casually mentioned killing the snake with a shovel. WTF?! The poor snake was harmless, and a natural antidote to rats and mice. Why didn't he stick it in a bag and carry it off into the woods? I feel obligated to respond in a way that lets him know I disapprove of what he did, and maybe gently suggest a different course of action the next time he encounters a snake (or lizard or bird).

My dad was never a big fan of nature or the environment. He was raised back in the day when the wilderness was the enemy. He used to cut down trees like crazy when I was a kid, for fear they'd fall on the house in a storm. He had an ax, hardhat, a winch-thing to pull the trees over in the appropriate direction, etc. He saturated the ground around our house with DDT, before or just after it was banned, as a defense against termites. And we had well water! When he moved to Florida, he proudly told me how they drained and filled marshland to build his housing development, and planted the town with non-native species, plants and trees from the northeast so New Yorkers like him would feel at home. It's not that he doesn't understand and appreciate science in general, he did work in the aerospace industry in the 1970s, but he believes that nature exists to be conquered by mankind in an eternal struggle.  

I'm not exactly a crunchy barefoot worshiper of the earth goddess, but I believe that humanity should basically leave nature alone, and preserve wild places and living creatures as best we can. If there was a snake in my yard, I'd welcome it as a natural predator of rodents and pigeons in the neighborhood. Dad and I are definitely not on the same page here. Hmm, my response to his email should be interesting. How's this: "Hey dad, thanks for murdering an innocent snake, does your wife have a fur coat, too?"... uhm, I'd better tone that down a bit!   

 

Salt Wars

  • Feb. 15th, 2007 at 10:06 PM
Over the past 48 hours, I've shoveled, chipped, and swept away any trace of ice, snow or slush off of my stoop, parking space, and sidewalk in front. Naturally, some fool either in the employ of my building or the city or the nearby commercial buildings keeps throwing rock salt all over my handiwork. Each time I sweep it up, and each time it reappears. I guess I can thank our overly litigious society for the mess and pollution, god forbid anyone slip on the clean bare pavement I worked so hard to reveal. 
And where do you think all the salt ends up? On my shoes, in the house, in the car, in the greenery, and eventually in the Chesapeake Bay. A little bit on icy patches is fine, but the shotgun approach, no, make that the carpet-bombing approach, is counterproductive. After walking around outside, I can taste the salt in my mouth. Isn't that ridiculous?
