Using Less Paper

The government of Zimbabwe was recently dealt a blow by the paper company that used to supply banknote paper to the country. They decided not to sell to Zimbabwe even though, given the hyperinflation, I suspect they were a good customer.

Now comes news that Zimbabwe is resetting its currency to remove 10 zeros from all denominations.

I can't resist… This will allow the government to print narrower bills to conserve paper, a move being lauded by Western environmentalists. None of the millions of billionaires in Zimbabwe could be reached for comment.

Energy Resilience

Andy Grove, former CEO of Intel, has written an article for The American titled Our Electric Future in which he recommends a transition toward using electricity instead of petroleum to power the U.S. transportation system.

He rightly dismisses "energy independence" as a worthwhile goal, instead making "energy resilience" — reducing the likelihood of, and increasing our ability to endure, supply disruptions — the standard. He argues that electricity should be the backbone of national energy policy.

I don't like one of his reasons:

Oil moves to the highest bidder. Fleets of tankers carry it across oceans day and night. Natural gas can also move around, but with extra difficulties. On land, it can be transported in pipelines, but to carry it across oceans requires liquefaction and expensive, high-tech ships that can carry this liquid in strong, deeply cooled containers.

Electricity can be transported only over land. In other words, it is sticky: it stays in the continent where it is produced.

The "stickiness" of electricity is a disadvantage. This stickiness means we have to generate electricity locally, which provides protection against it being bid away by other nations. But that also means that we can't bid it away from other nations.

The very fact that we're able to import oil, a practice much maligned by the energy independence crowd, means that we have access to (much) more than we're able to produce ourselves. That's a good thing! We import it because that's cheaper than domestic production. With electricity we don't have the option of importing on such a grand scale.

Grove recognizes that electricity can be generated from many different fuels, reducing the risk of a fuel-based supply disruption. But as anyone who lived in California in 2000 could say — and incidentally, didn't Grove? — the electricity generation and distribution infrastructure itself can be a significant point of failure. If California could have hypothetically solved its energy crisis by importing electricity, even from a foreign cartel, that would have been wonderful!

We live in a world where just about everything — from a hairdryer to the Internet — runs on electricity. A big exception is the transportation sector, critical to the movement of people, production materials, food, and even fuel. Transportation uses more than half of all the petroleum consumed in this country. If we don't convert a large portion of the transportation sector to electricity, we cannot make real progress toward energy resilience.

It's important to underscore the fact that although oil prices have risen dramatically, there have been no shortages outside of actual natural disasters. The market, and this fuel, works. I look at petroleum and see an energy source that's already resilient! It looks more resilient to me than electricity, where California demonstrated that misregulation could create a crisis even with no natural disaster in sight.

To start with, the U.S. government should lead the way by requiring that a growing percentage of new cars be built with dual-fuel capability. These dual-fuel cars would have both an electric engine and an auxiliary gasoline engine to augment it. The car would run on electricity, and after the batteries were depleted, it would switch to running on the gasoline engine.

Sorry Andy, you've completely lost me here. Why, pray tell, should the government impose your preferences on everybody else?

Such dual capabilities are often built into machines to help with technology transitions. When DVD players first came to market, they were often combined with a VCR tape player so the consumer could choose if he wanted to watch a movie in VCR or DVD form. Eventually the DVD player became the default standard, but only after a period of time that allowed consumers and the broader market time to adapt.

I'm confused. Didn't this happen without government intervention?

Laptop computers today come with both wireless and wired Internet connections. If you are in a hotel, you can choose to use wireless service or plug in to the hotel's wired connection. I expect wireless connectivity eventually will be sufficiently powerful and accessible to obviate the wired alternative.

Now I'm even more confused. Didn't Intel, not the government, cause this to happen? Please please can't we take credit for this? I want my stock to go back up…

Grove admits that the market will cause the transition to electric vehicles on its own. But he's dissatisfied with the pace. He thinks he knows what the optimal transition speed is — he thinks it should be faster. He wants to subsidize the transition. He thinks he knows better than you how to spend your money.

I could argue (but won't bother going into detail here) that the free market rate of technology transition is the only objectively defensible rate of transition, and that therefore the currently already-subsidized rate of transition is too fast and should be slowed down by ending the subsidies. I at least have economic theory to ground this argument. I'm pretty sure I saw Grove just waving his hands, without considering the impact of his subsidies on Sumner's Forgotten Man.

Grove is a genius, and he has my high respect. But he doesn't know the right way to spend my money, and he doesn't know the right way to spend yours. Hold on to your wallet.

Treesonously Bad Pun

A couple days ago I was out hiking with a group from work, including our intern. In a spot with an amazing view deep into the forest, I asked her to take a picture because I thought it would be fun to send it to the rest of my team at work and have them guess how many trees are in the picture. To make things interesting I added that "the closest guess may win a potentially valuable prize!"

How many trees?

Tim knew exactly the right answer:

Tree thousand tree hundred dirty tree

Six Days to Spam

I receive any and all e-mail sent to the domain. This enables me to use arbitrary addresses (in my domain) as read-only e-mail inboxes. If I sign up for something online and use a new e-mail address, I can filter mail based on the address they sent to, and I can also see who sells my address to spammers.

Last weekend I upgraded the operating system on one of my computers (from OpenBSD 3.9 to 4.3) and as I was doing that I also configured the system as a Tor relay. I invented a new e-mail address to be the administrative contact for the relay. The list of Tor relays and administrative contacts is available online (indeed, that's how clients find the relays) but this e-mail address has never been used anywhere else for any purpose.

Today, six days after I started the relay, I got my first spam. I have it on good authority that my contracting company is due a payment of US$15.5M from the Nigerian government. Awesome. :) Who knew you could make money on the internet?
