Nuclear Energy by David Bodansky

Nuclear Energy by David BodanskyI just finished David Bodansky’s 600+ page tome Nuclear Energy.  It’s almost a textbook, but not quite.  I don’t know who the intended audience is really.  Other than me.  Similar genre, broadly, as The High Cost of Free Parking.  A comprehensive overview of a technical topic, for those with a long attention span and no fear of numbers.  I decided to read the book because of the recent turn toward nuclear power that some environmentalists have taken.  There are many publics that react strongly, and negatively, to the idea, but I don’t trust public sentiment to be rational any more than I can manipulate it.  Bodansky did an admirable job of remaining neutral throughout the book, on a topic that almost universally devolves into something resembling a religious debate.  As a result of this reading, I’m much more positive (or rather, less negative) about nuclear energy than I was before.  I think that my position, which I hope can count as an informed one, now closely resembles that of Ralph Cavanagh, as articulated in this debate with Peter Schwartz hosted by the Long Now Foundation.

The main questions I had coming into the book were:

  1. Can nuclear energy be done responsibly?
  2. What would it take for it to scale up meaningfully?
  3. How would it compare in costs and risks to renewable energy sources, if it were done responsibly at scale?

The answers I came away with were that yes, it probably can be done responsibly, and at the scale necessary for it to be meaninful as a long term source of primary power globally.  However, if it were to scale up responsibly in the long term, it seems that the associated costs would likely end up being greater than for renewable energy sources.  So I guess I’m supportive of having the so-called “nuclear option” on the table, in competition with any other carbon free power source, with the significant caveat that the cost of the nuclear power being considered correspond to a responsible, long term, large scale deployment.  The scenario I foresee needing to be avoided is ending up with an unfair comparison, between short-term and/or irresponsible and/or non-scalable nuclear power, and renewables — especially renewables as priced before the solar power industry has obtained whatever economies of scale there are to be had in their niche.  One might be able to make a persuasive argument that we need to use nuclear power as a bridge between fossil fuels and renewables at scale, but I haven’t heard that argument made yet.

  • Your Backyard Farmer – A couple of women in Portland who will do your organic vegetable gardening for you! They visit dozens of personal gardens all over Portland every day to tend their micro-fields, and can help teach you how to grow too. If we're willing to pay people to come do landscaping (and certainly "we" seem to be willing to do that in Pasadena), why not vegetables too? I've thought about this business model in the past too. Seemed like it would probably be a lot of work, and not a whole lot of pay, but it does have the advantage of starting up with virtually no capital. Just hand tools, seeds, and smiles 🙂 (tagged: gardening food green urban sustainability business )
  • Are we ready for honesty? | Jerusalem Post – A right-wing Israeli talks about what an honest discussion about the Israel-Palestine conflict would look like. Should they annex the West Bank formally, and set up a greater Israel in which the Arabs cannot vote? Should they expel the Arab Israelis in exchange for removing all the settlers? It might sound like crazy talk… but at some level, the questions he brings up are the real questions Israel has to deal with, no matter how ugly they might be.

  • China Begins Its Transition to a Clean-Energy Economy – Lots of great plans from the Chinese leadership, but are they actually enforceable, implementable, or verifiable, even by China's own government? And even if they are, the terrifying fact is that they don't end up reducing emissions, they just end up slowing the rate of increase, what what we really need is a virtual cessation of CO2 emissions worldwide. The universe is not required to be accordance with human ambition. (tagged: energy china climate policy politics )

What kind of bicycling should Pasadena support?

Zane and Rich,

During our last BMP meeting we discussed the idea of the City sponsoring more biking related events.  I was over at Pasadena PD today dealing with my stolen and then recovered bikes and saw this flyer. This is exactly the type of events we were discussing.  This also ties in nicely with our BMX track idea.

I certainly don’t see anything wrong with a BMX track as a city recreation facility if there’s demand for it (especially if it means less conflict between BMX riders and those would would prefer that they not practice elsewhere in the city), and it may well be a good Police fundraiser, but I don’t see this kind of event as particularly constructive in the context of getting people to consider bikes as a viable means of transportation within the City, because it focuses on bicycles as a means of sport (over function) and on experts (rather than everyone).  Which isn’t to say that bikes aren’t sport — of course they are — but training and competition amongst the elite is very different than active and inherently non-competitive transportation.  The Tour of California falls into the “elite” category too: it’s spectation, vs. participation.

Michael Pollan on Deep Agriculture

I can’t believe how much I enjoy the Long Now talks.  Thoughtful and intelligent people, usually talking about things I happen to think are important, and interesting.  I almost feel like it’s a re-invention of the oratory form.  I’m glad they’ve gone to the extra effort of doing a high quality production, with decent microphones, and well illuminated speakers in front of a dark background, multiple camera angles and only occasional (but necessary) cuts to the slides on screen.  Not all thoughtful and intelligent people are good orators, but I guess I’m willing to put up with some unnecessary “um” and “uh” syllables thrown in if the ideas on offer are good enough.

Michael Pollan gave a recent talk, unsurprisingly to a full house (it’s SF after all), entitled “Deep Agriculture“, which was largely, but I think not entirely, a synthesis of his previous books.  The first point he made was that America’s healthcare costs, our industrialized agricultural system, climate change and the ultimately limited supply of fossil fuels are really all part of the same system of issues.

We spend roughly twice as much per capita on healthcare as do the twenty nations which have longer life expectancies than we do.  A significant portion of that excess spending is on chronic “diseases of the rich” which are intimately linked to diet: obesity, heart disease, diabetes, etc.  At the same time, we spend a smaller proportion of our incomes on food than any other nation in the world, and probably any other nation in history.  If our cheap diet is generating high healthcare costs, then it isn’t really all that cheap.

  • Math and the City – The same scaling laws seem to apply to both cities and organisms: infrastructure requirements per capita (or per unit body mass) go down as population (size) go up. Not so surprising, since both cities and bodies are connected to themselves by networks of wires (neurons) and tubes (pipes, transportation, blood vessels) (tagged: urban design economics sustainability transportation infrastructure biology )
  • Sustainable Transport that Works: Lessons from Germany – A 60 page report on how Germany has transformed its urban transportation systems over the Post-War period, moving toward more public transit and bicycle infrastructure, the costs, benefits, effects, etc. What has worked, and what hasn't.

  • NASA Gets Out of Satellite Servicing Business – And good riddance. Yes, the capability was amazing, but expensive and unnecessary. For the price of *each* Hubble servicing missions, we could have launched an entirely new Hubble-class telescope on a rocket. The shuttle is a solution in search of a problem. Someday we'll have a real reason to send people into space — e.g. long term scientific exploration of Mars, or if we're lucky, the beginnings of a two-world civilization — but until then, we're just going around in circles, and forking over hundreds of billions unnecessarily to the aerospace industry. Better them than the banks… but that's really no argument to stand on. (tagged: space nasa politics policy )
  • Buying farmland abroad: Outsourcing's third wave – I don't know how anybody can think this is going to work long term. The whole point is to have food when there's a crisis, but in case of crisis, these deals are going to go down hard, unless those on the receiving end are willing to deploy their militaries on foreign soil to protect their investment. Which isn't impossible, but certainly doesn't seem like a great deal for anyone. (tagged: agriculture food china africa sustainability economics trade )
  • Crack Gardens – No, not gardens in which you grow crack, gardens growing out of cracks. A little creative jack-hammering opened up some fissures in this concrete slab, out of which a garden now grows. An homage to the tenacious plants that will take our cities apart when we leave.

What Are Cities For?

Kurt recently asked me:

Assuming (1) that you like the outdoors, open spaces, gardening, etc. and (2) that you would prefer high-density urban design to low-density, suburban, car-oriented sprawl, then how would you fuse these two together in an ideal town? If my assumptions are wrong, I realize my question is moot.

I am asking because I like the idea of owning acres of land, but not the idea of having to drive everywhere, and I wonder if those two desires are mutually exclusive.

and it got me thinking about what my ideal city would be like, and how close one can get to that in this lifetime, especially on this continent.  I’m going to make this an exercise in creative idealism.  Kurt’s assumptions are right, and I do feel torn, especially having grown up in a rural area, on 8 acres of oak woodland with a creek running through it.  I am completely sympathetic to the pastoral urge, but that urge is not and never has been satisfied by the suburban existence which has come to typify the American experience in the last half century.
