I Didn’t Know My Therapist Was In the Audience

She came up to me afterwards, and I was glad that she had seen me doing something other than sitting in her office whining.

This was the third time my dance partner (not my therapist, though the boundaries do blur) and I did a demonstration as part of a dance event. I was really working on smiling and not acting like I was doing martial arts (see Not the Snake).

My dance partner and I felt good about this performance when it was over, but after watching this video we found lots of things to tighten up for our second performance of the same routine the following Saturday, which went better. Video of that may be posted sometime, but right now it is stuck in media transfer.

Addendum 1/30/07: After watching the tape of the second performance, we are less than thrilled with that too! So we'll leave just the one video up here for now.

Most of these moves are in the Dance Vision (DVIDA) American silver cha-cha syllabus, but we shortened them significantly to make the routine a little more intense. Again, the video is a little smoother on YouTube.

Not the Snake

This was the second time my dance partner and I did a demonstration at a dance event. It was back in March of 2006, and I had spent weeks worrying about the death drop at the end. It’s not the move that gets you -- it’s the face. Before taking up ballroom dance, my only movement experience was in a Filipino martial art called arnis, and there we generally have a very sober expression and exhale sharply in the midst of doing moves. That just does not fly in most ballroom dance. Luckily, in this particular performance, we “overturned” the whole routine a little and I ended up facing away from most of the audience members when the death drop occurred. And in compressed video, you can't see it that well anyway! Yes, thank goodness for bandwidth limitations, the great equalizer . . .

My dance partner, on the other hand, is a natural entertainer, having spent her life in jazz and other dance forms. This is clear from the video, regardless of compression or frame rate. Speaking of which, it plays a little more smoothly over on YouTube, so you could watch it there if you want, or below.

This is mambo from the Dance Vision (DVIDA) American silver syllabus.

Getting it Done

Today we cheated. We had followed our woman to the self-storage place where she was storing her stuff for the move. The line producer, back at the hotel/office, was calling the storage place to get permission to videotape there. Just as we arrived in our van, following our woman, the line producer called our director to say that we could not shoot there -- the clerk had said "no."

"It's too late," our director told her over the phone. "We're here. We just pulled up now."

Love of Diesel

I’ve been in conversations about alternative fuels recently. Folks say that methanol and ethanol as gasoline substitutes may lead to competition with food crops for freshwater and land space. Hydrogen is probably not feasible as a fuel either because it is expensive to make, and takes so much space to store.

Vin Diesel is a strapping young actor, but even his energy output is a mere drop in the bucket compared to our nation's needs.

“. . .to replace all transportation fuels in the US, we would need 140.8 billion gallons of biodiesel, or roughly 19 quads (one quad is roughly 7.5 billion gallons of biodiesel). To produce that amount would require a land mass of almost 15,000 square miles. To put that in perspective, consider that the Sonora desert in the southwestern US comprises 120,000 square miles. Enough biodiesel to replace all petroleum transportation fuels could be grown in 15,000 square miles, or roughly 12.5 percent of the area of the Sonora desert (note for clarification - I am not advocating putting 15,000 square miles of algae ponds in the Sonora desert. This hypothetical example is used strictly for the purpose of showing the scale of land required). That 15,000 square miles works out to roughly 9.5 million acres - far less than the 450 million acres currently used for crop farming in the US, and the over 500 million acres used as grazing land for farm animals.”


But, the article says, it would be better not to concentrate the algae ponds in one place, but to spread them around the country. One reason for this is, the ponds could be constructed where agricultural waste is accumulated and could be used as food for the algae. I suppose the sea water would have to be pumped to these locations.

Regarding costs, here is another long quote citing another study of a certain kind of algae pond construction. I love how the authors double the cost of pond construction, to give a cautiously pessimistic estimate:

“In ‘The Controlled Eutrophication process: Using Microalgae for CO2 Utilization and Agricultural Fertilizer Recycling’, the authors estimated a cost per hectare of $40,000 for algae ponds. In their model, the algae ponds would be built around the Salton Sea (in the Sonora desert) feeding off of the agricultural waste streams that normally pollute the Salton Sea with over 10,000 tons of nitrogen and phosphate fertilizers each year. The estimate is based on fairly large ponds, 8 hectares in size each. To be conservative (since their estimate is fairly optimistic), we'll arbitrarily increase the cost per hectare by 100% as a margin of safety. That brings the cost per hectare to $80,000. Ponds equivalent to their design could be built around the country, using wastewater streams (human, animal, and agricultural) as feed sources. We found that at NREL's yield rates, 15,000 square miles (3.85 million hectares) of algae ponds would be needed to replace all petroleum transportation fuels with biodiesel. At the cost of $80,000 per hectare, that would work out to roughly $308 billion to build the farms.

The operating costs (including power consumption, labor, chemicals, and fixed capital costs (taxes, maintenance, insurance, depreciation, and return on investment) worked out to $12,000 per hectare. That would equate to $46.2 billion per year for all the algae farms, to yield all the oil feedstock necessary for the entire country. Compare that to the $100-150 billion the US spends each year just on purchasing crude oil from foreign countries, with all of that money leaving the US economy.“


Okay, so it’s just a study. But as far as I can tell, it makes biofuel production from algae look like something to be explored. It is an alternative fuel source, not only to petroleum, but also to biofuels grown from existing land crops, which may a dubious prospect.

Swing Dancing with Lesbians

I get bored with the ten or so swing dance moves I know. At dances, women get to follow all the moves known by the different men they dance with, but we men can lead only what we have learned. Seeking to inject some excitement into a recent swing event at the Durham Armory, I decided to venture across the floor and ask some of the lesbians to dance.

Log Functions

Black and silent, the wood stove devours whole logs that would have taken me hours to split. Many are fungus-covered and rotting, but what's the difference? Oxidation is oxidation. Some logs barely fit into the stove and require much jostling that risks causing other burning pieces to spill out onto our wooden rental-house floor. They call to mind my mother's frequent complaint to me, "You're just like your father." It was from him that I learned the trick of staggering in the front door and across the living room with my fingertips barely hooked around the edges of a full oak-trunk cross-section. Dumping such a log into the fireplace took skill -- it had to hit the fire just right, or it would roll back out with sparks already attached to its cold bark, pulling smoke in its wake.

Other daddies had neatly split, 3-cornered pieces of wood, one to a hand for each trip from the woodpile. So uniformly cut they were, I couldn't believe those daddies had split them themselves. And they probably could not explain why split wood burns better anyway. They were humanities professors. In our small college community, it was my dad who knew he was pushing the limits of physics with his big logs, since fires only burn on the surface. What you need in the fire are several surfaces facing each other to share heat, not one whole cylinder of chilled trunk with most of its mass far removed the surface. (Dad liked the skins to be left in his mashed potatoes too.) But if you can get nature to do the work, then you're that much ahead of the game, right? And so, like my dad, I push it. I bring in a big log and cram it into the flames and slam the iron door, locking it out of sight. By morning it will be gone, another weight and labor vanished from the earth.

Iraq War Haiku

Colonel Rotkoff in the Pentagon wrote haikus during the buildup to the Iraq war, and some can be read in slate.com's excerpts from Woodward's "State of Denial" here:

I have written my own Iraq war haiku:

Can't find bin Laden?
Unleash militant Shiites
U.S.A. knows best

The Latest Godfather

When I go see a movie, I'm always looking for "The Godfather," and I'm nearly always disappointed. But this season, a modern "Godfather" has arisen, and it is "The Good Shepherd." It's dark and brooding and full of men doing important man things that they presume women would never understand, in the service of some greater cause that kind of loses focus the more you think about it; and you can't follow the plot at all, which is a quality I admire actually, because it means the characters are so well mired down in their dismal scenes that they just don't have a free hand to help the audience. It's almost as if Robert DeNiro directed it and Francis Coppola produced it. If we audience members can't keep up, then that's just tough nuggies, and maybe we should take our popcorn tubs over to see Ben Stiller instead. But we're the thinking movie goers at Southpointe with an "e," so we stay put and keep trying.

Permalinks

So it comes to this. Already, on my third blog entry, I'm talking about how I don't know Jack about blogging. For instance, in that entry explaining the U.S. in Iraq, you can see how messy it is. I did not even do the links in HTML, I just pasted the URL's on there. But nobody will ever read that, so I shouldn't get too wound up about it.

Looking at other people's blogs, I see these things called "permalinks." I don't know what a permalink is. There are so many of them, that it seems that the very pipeline of Internet/blog communication is grounded in them. And while, perhaps, I would do well to learn about them, I can't help but ask, what happens when this global warming thing really gets under way, and all the permalinks start melting? Won't our Internet pipeline buckle and spring a leak, causing untold environmental damage? Think about it.

Iraq War Reading List

I have conservative and neoconservative relatives who support the U.S. invasion of Iraq. I am at odds with them on this matter. One relative asked me for a reading list of news sources alternative to Fox and other TV news outlets she watches, so that she could read what I've been reading about the Iraq war, and see my point of view better. I am supplying her with the following information. Bear in mind, this is addressed to a supporter of the war.

Review of Beloved

I finished reading Toni Morrison’s Beloved, and between you and me, I didn’t like it all that much.
