Modern Geekery

The folks at Worldchanging point out the critical flaws in Walkscore. I had a similar take on the site about a year ago, though one that was a lot less in depth. Check out the Worldchanging article for a very insightful take on why WalkScore’s approach is outdated (terrible business model), as well as some commentary on the Second Life tool called Carbon Goggles.

My take on Carbon Goggles is something between “obvious” and “pointless.” Second Life has utterly failed to impress me in the suspension-of-disbelief department, thus I’m much more likely to be moved by data on carbon impact than on something that gimmicky. I suspect that while such gimmicks do tend to be effective in getting points across to folks who are not intimately familiar with the subject at hand, the Second Life audience is one that is not ill-educated on climate change.

I just read this piece by Alex Steffen on the WorldChanging blog and highly recommend it. The key quote from the piece, in my opinion, is this one:

[I]f we’re going to avert ecological destruction, we need to to not only do things differently, we need to do different things.

What he’s saying here is something that I’ve pointed out to my colleagues in the innovation community: sustainability is not about making things with less stuff, or that last longer, or that aren’t toxic, or even that can be infinitely cradle-to-cradle recycled. Sustainability requires us to invent things that make it possible to live more sustainably. If the things, the stuff, that we have and use make it easier to live sustainable lives than to not do so, then we will live sustainably.

Its not an easy problem to solve, for the same reason that truly groundbreaking innovation is not easy. It is pretty straightforward to imagine a novel solution for a market that already exists. It is much harder to invent a new market. I think that the kinds of products that will help people live sustainably are products for a market that doesn’t exist yet. Our business strategists don’t know how to value them, so our market analysts can’t compute a return on investment, so no investment is made. And truthfully, our scientists and engineers don’t always have the global perspective necessary to understand what types of solutions are necessary.

The point of Steffen’s article was to underline the importance of community in making these changes in our systems. I think that it is also important to understand the systems themselves. As we grow in our understanding the network of interactions and dependencies in our economy and our society, this understanding will allow us to break out of unsustainable patterns and replace them with ones that are equally understood, but are sustainable to the best of our knowledge. And because we’ll be building from a base of understanding, we’ll be able to look at them in a rational fashion 40 years from now when we understand the ways in which the new patterns are not sustainable.

It may be that at first, these more-sustainable patterns will be obvious. Things that folks like Steffen have been telling us for years, like community gardening, reducing sprawl, and increasing bike transport. But as with everything else, the low-hanging fruits will be quickly exhausted. At that point, progress will only be made by deeper understanding. It will be interesting to see how the tools for gaining that understanding develop.

I posted an article earlier critiquing the media reaction to the recent reports on biofuels and land use management. Worldchanging has just posted a similar, fairly in-depth, critique as well. Their analysis goes more in depth into the specifics of each report, so I highly recommend it. What they do point out is that the Science articles are nuanced and that it was clear that the media in general either missed the nuance or ignored it.

Robert Rapier, over at the R-Squared Energy Blog, has posted an interesting quick look at using ocean currents as a source of energy. This is, of course, another way of capturing part of the planet’s total solar energy budget as well as some of the energy from the tides as well. Interesting read.

In regards to my previous post on the recent studies on biofuels, WorldChanging has posted an article about the issue, citing a study released by the Sierra Club as well as the Science report. The WorldChanging blog post mentions that the Science report “reinforced the urgency of moving to second-generation biofuels.”

In considering this topic, I think something else extremely valuable is coming out of the biofuel boom. We’re learning how to quickly estimate environmental costs.

I posted a quick note earlier about installing porous asphalt in a green community in Oregon. In that note, I made an offhand comment questioning the water quality coming off the road. After posting the article, I also wondered if the lifetime of the surface would be shorter in areas prone to freezing weather due to the expansion and contraction of ice in the pores.

It turns out that had I been less lazy in doing my research, I’dve had all these questions answered much more quickly. I just found a great article on porous asphalt that covers a lot of topics, including water quality (82% removal efficiency for organic carbon) and lifetime in freezing weather (longer than standard asphalt).

Additionally, the article points out that the porosity allows for less use of salts for deicing and that:

The water drains through the pavement and into the bed below with sufficient void space to prevent any heaving or damage, and the formation of “black ice” is rarely observed. The porous surfaces tend to provide better traction for both pedestrians and vehicles than does conventional pavement. Not a single system has suffered freezing problems.

Pretty darned cool, if you ask me. One has to ask what the factors are that are keeping this from being installed in every new parking lot being built. Undoubtedly, the subsurface strata affect the design - this is also covered in the article - but I suspect strong that the major factor is simply ignorance.

On a lighter note, the best quote from the article is this one: “Fortunately, even without regular maintenance, the systems continue to function (we routinely send graduate students and recent hires out in hurricanes to confirm this).”

After reading this post from WorldChanging, I wondered a bit about the wisdom of porous pavement. Sure, I understand the issues that are caused by stormwater runoff, but I’m a little concerned about what gets washed off the streets through the pores in the pavement.

There are probably good ways to handle this, including beds of Stropharia mushrooms on either side of the road to mycoremediate the waste water stream or even a filter layer underneath the pavement.

I also wonder what is actually underneath that pavement. Is it the sand and gravel bed that typically underlies roadways? Or is it something else more porous? The percolation through a layered gravel bed might reduce the pollution in the water that passes through.
