During the summer of 2009, the US government operated an economic stimulus program called Cash for Clunkers (C4C). The objectives of this program were to provide an immediate economic stimulus to the US economy, which was currently in recession, and encourage the replacement of inefficient vehicles for efficient ones in the private US transportation fleet, thus reducing overall fuel consumption on a national level. In addition, the government championed an expected reduction in pollution, especially smog forming emissions and greenhouse gases. An analysis summary of this program in meeting these goals based on the information available in September 2009 just after conclusion of the program follows in this article.

Environmental issues such as conservation and biodiversity are often seen as peripheral to our lives or the problems we face, but nothing could be further than the truth. This world is habitable because of the weathering of rocks and the death and recycling of organisms, because of the filtration, oxygenation, and water capturing functions that plants carry out, because of consumers’ roles in suppressing the populations of plants and other animals and producers’ conversion of solar energy to chemical energy. All of that happens within the Earth’s ecosphere and the ecosystems that comprise it, and all of it is self-sustaining and self-maintaining. Or, at least, it is until we start interfering with it.

You and your team doubtless have a long list of priorities, many stemming from the current economic recession; despite this, I hope you find the time to address a few issues, issues which, in the long run, will determine whether we have the time and luxury to address the remainder.

There has been a lot of talk recently about whether economic markets have imploded due to over-regulation or under-regulation. Although most pick up that argument with their own particular political biases, it is a difficult question to answer not least because many governments actually act in both directions at the same time. But, let us look at a related but different aspect of civilization: innovation and progress.

In the same way that economics experiences cycles, booms, and busts, innovation and progress when considered as a market of ideas also experiences those things. This earlier article on regulation explains some of this, but we are going to take this idea a few steps further. Read the rest of this entry »

Showing that we can afford space exploration, globally speaking, is not nearly the same as showing why we should pay for it. Despite the fact that we can make room for it in our list of priorities if we choose to, there are still many other priorities that are suffering from a lack of (or those that have died from an absence of) funding. Given budgetary realities, why should we fund space exploration? Read the rest of this entry »

One discussion that has surfaced repeatedly since the dawn of the Space Age is the worth (and role) of space travel, especially in the context of all the other priorities that demand attention, such as ending world hunger, developing flying cars, and creating a new energy infrastructure. We have no real shortage of challenges and crises on our doorstep- why should we take some of our hard-earned resources and spend them where they may or may not do any good?

If we consider development to be the general increase in well being of a population, then we have to recognize that there are times when the increase in one type of measure (real income) is countered by the negative action of another type of measure (disease rates). In these cases, government often steps in to regulate the problem. However, there are times when government regulation is necessary and other times when it is ill-advised. How can we tell the difference? Read the rest of this entry »

So, what happens when the very actions that we each individually take to improve our lives in the end cause detrimental consequences to all of us? The sage might say that the road to hell is paved with good intentions, and she might be right. But, does it have to be that way? Are we doomed to one step forward and one step back? Can we anticipate the things that might go wrong? And, how important is the collective good when compared to personal freedom? Read the rest of this entry »

In this earlier article on the new CAFE standards, I found that depending on the assumptions made for the number of future miles driven, restricting the speed limit to 55 miles per hour would be a more cost effective and more energy efficient solution than changing the CAFE standard. That analysis only considered the total amount of fuel consumed between the two options. Now, let’s take that analysis a few steps further. Read the rest of this entry »

Sustainable technology is an idea that may produce a new level of real progress around the world. But often today, the term is more of a marketing badge that may or may not prove to be true when put to the test. I have written before about sustainable technology and some of the problems with realizing that idea. In this article, let’s consider a set of objectives that we can use to actually measure whether something is sustainable. Read the rest of this entry »

What is the state of the American university system?  Does it produce the types of professionals needed to keep the American economy strong and innovative?

We often hear a lot about how our contemporary economy requires plenty of professionals skilled in science and technology to maintain a healthy rate of innovation. There are are many reasons why science and engineering degrees are often used as barometers or leading indicators of the future state of innovation of the American economy.

Progress via a True Global Internet

In our contemporary world, one of the most important factors constraining the growth of societies is lack of information. In some places, infrastructure is not sufficiently developed in communications and electricity and the availability of electronics in the market to even allow people to connect to the information available via the internet. In other places, totalitarian governments partially or entirely limit the access their people have to the information available on the internet. Read the rest of this entry »

When Subsidies are Hard to See

When we think of our governments subsidizing a particular industry we usually envision a nice big check sent to them every year to the tune of millions of dollars from tax revenues. Sometimes, instead, it is that industry that is free from a particular tax that most others have to pay. But, what if instead there are payments in kind that elevate one industry or one form of technology over another. Would we recognize those things as government subsidies?

Stay Focused on the Big picture

This is the fifth article in a five part series.

In this series, we have been outlining a evidence-based, constructive method to address the issue of climate change. While using this method doesn’t eliminate any disputes, it does change them from one of attacking philosophies, which are not easily changed, to disputes about data analysis. And disputes about data analysis although sometimes nearly as heated can eventually be objectively resolved. The earlier articles focued on defining the real problem, determining causes, developing solutions and evaluating policy. While those articles briefly covered all of the major aspects of the method I am advocating, there are other important ideas that must be agreed upon to some degree by those participating in the process.

Evaluating Solution Effectiveness and Translating Analysis into Policy

This is the fourth article in a five part series.

To date in this series, we’ve looked at objective measures of how to frame a problem, how to determine the causes of that problem, and consider implementing a robust solution to the problem. In the last article, we examined what to do about risk in an environment of uncertainty both from the standpoint of the problem and in the effectiveness of our solutions. In this article, I am going to discuss how we could form policy in a non-political fashion when given that kind of situation. Read the rest of this entry »

In honor of Earth Day on 4/22 (a little late, I know), let’s consider the relationship between “green” production and conservation.

Our question is does conservation or “green” production result a greater positive impact regarding our use of resources. I am going to take the case of paper, as it is relatively simple product to manufacture, is a major waste product, and can be easily recycled.

As of 2000, paper consumption in the United States was approximately 324 kg per person. Americans recycle approxmately 38% of that total, and of the remainder that is thrown away, it makes up nearly 40% of the municipal waste stream eventually being incenerated or deposited in a landfill. Recycling has been growing slowly, however, only growing from 20% in 1921 to 38% today. Consumption has grown faster increasing more than 1% compounded annually or over 23% since 1990.

Evaluating Likelihood and Addressing Uncertainty when Applying Solutions

This is the third article in a five part series.

In the first two articles in this series we looked at identifying a problem and a functional understanding of that problem and then at determining all the causes of that problem. Now, we are going to consider how to take account of uncertain data regarding future events both in the probability that they may occur and in the degree to which they might occur. People are generally bad at statistics, which makes this part of the risk assessment process counterintuitive at times. However, risk is something we do accept on a daily basis, and so I will try and find some analogies. Again, this series is about taking politics and argumentative posturing out of the decision making process regarding climate change. To be sure we adhere to that premise, I will continue to make my examples totally neutral regarding the data and whether we are talking about a warming or cooling climate; I am discussing the decision making process.

A Root Cause Analysis on the “Failure Mode” of Changing (Increasing or Decreasing) Temperatures.

This is the second article of a five part series.

In the last article I outlined our functional model of the Earth. According to that model to explain why the current temperature of earth is the way it is, we have a primary energy input from the sun, and secondary energy inputs from other astronomical sources and internal energy from the Earth itself. The properties of the Earth that effect the temperature are the reflectivity, the percentage of energy reaching Earth reflected back out into space, and the emissivity, the ease at which the energy Earth contains can be released into space (cooling at night for example). The goal in this series is to address climate change in a real, technocratic, nonpolitical manner to elimate the arguing and posturing, and outline a process whereby people could identify what problem exists and the best most robust solution.

A Risk Assessment Approach to Climate Change Policy

This is the first article of a five part series.

It is difficult to find a more hotly debated public policy issue today than the one about potential regulatory actions related to global climate change. Much of this debate is emotional focused on various groups’ attitudes toward government action and personal responsibility, pessimism or optimism related to human interactions with the environment, and other philosophical differences. That being what it is, I think a different approach could show us the way out of that kind of divisive argument and produce positive action in an amount properly proportional to the nature of the threat. So, in a series of 5 articles, I am going to address this issue, not as a politician or a policy advocate, but as an engineer considering options and trying to reduce the risk associated with a particular problem. To maintain the non-partisan nature of this series, I am going to assume that increases or decreases in global temperatures are equally likely, and since, in theory, they have related solutions, it does not diminish the outcome of the analysis.

What would more effectively reduce pollution from small vehicles?

Recently, there was a significant political argument in the United States about the costs and benefits of increasing the Corporate Average Fuel Economy (CAFE) standards. Increased efficiency, the argument went, would reduce the consumption of fuel, and therefore help restrain fuel prices, also reducing pollution from vehicles causing reductions in greenhouse gasses and even more important things in the immediate term including smog producing substances, which are a major concern in large cities with warm climates like Los Angeles, Houston, Dallas-Ft. Worth, and Atlanta. The counter argument said that the costs would be too high, adding to the prices of vehicles, reducing auto industry revenue, eliminating jobs, and reducing passenger safety.

Back in the good old days…

Cultures seem to have their own ideas about what progress truly is and whether it exists at all or is just an illusion. Americans, in general, seem to have faith in progress over time, yet many continue to just as strongly express nostalgia for times past. Others have a more cynical view of progress believing life and history to be more cyclical, while others who have recently experienced opression have no doubt that progress is real and something to strive for.

Onwards and Upwards

Do we know what we are doing? Maybe the right question is do we ever know what we are doing? What are the true consequences of our actions today and tomorrow and hundreds of years from now? Are we responsible for those consequences or should we never be concerned with them?

I believe that too often we accept not having the answers that we could have. We have chosen not to know whether our ways of “helping” each other really turn out to be help in the end. We have chosen to push the solutions to problems we have today off into the realm of tomorrow. While some of that may be rational (I am fairly certain that my computer will be faster in 5 years), not all of it is. Read the rest of this entry »
