Being green makes good business sense, much of the time. While you obviously wouldn’t want a hospital run directly on solar power, it does make sense to build solar arrays in the right places, and wind farms in perpetually windy areas, and then hook these up to the existing power grid. In that context, running the hospital on solar power doesn’t seem like such a bad idea anymore. In medicine, we manage chronic pain by coupling a long-acting opioid with a short-acting, rapid-onset opioid. The long-acting agent is used to control baseline pain, and you never use short-acting opioids to manage baseline pain because of the greater duel risks of overdose and dependence. These agents are used to breakthrough needs only. In power generation, the metaphor is analogous: renewable resources provide your baseline power, and your coal- and oil-based electricity kicks in only when necessary. Thankfully, exothermic reactions lend themselves to relatively rapid cycling and are therefore suited to “as-needed” use.

Texas billionaire oilman T. Boone Pickens is seeing why it’s valuable to invest in renewable sources of energy. Not only is it good for national security, but it makes good business sense to invest in renewables. With any non-infinite resource, the market is subject to the forces of supply and demand. When supply drops, the price goes up. If demand increases because India and China need their share of the world’s petroleum supplies, prices for the US consumer go up, as well as the ancillary costs associated with anything that needs to be transported. As the amount of available petroleum decreases — as it’s steadily and inevitably doing — these forces increasingly affect the way you operate your business. For a company like National Grid, eliminating the twin problems of scarcity and competitive bidding are good for the bottom line.

Civil and structural engineers and architects are hopping on the green bandwagon as well. The first of them jumped on because it was hip and different, and enabled them to leverage a different kind of brand image to achieve financial success. Lately, though, buildings that are built to be more energy efficient make economic sense. In Sweden, Jernhusen AB is harnessing the body heat of thousands of commuters that pass through Stockholm’s main railway station. The firm believes that the system being designed can provide about 15% of the energy needed to heat the 13-story building being built next to Central Station. This system isn’t even particularly radical. It’s going to cost about $47,000, and will only require a few pumps and some pipes, since the ventilation system is already in place. I think it’s a safe bet that a 15% annual energy savings for a 13-story building will more than cover even the short-term costs associated with it, particularly in a city only ~1,000 miles from the Arctic Circle like Stockholm.

Since every mechanical system wastes energy in the form of heat, recycling waste heat is also becoming more popular. Estimates of the amount of energy lost in the form of heat — expressed in terms of electricity — from smokestacks in the US alone is at 50,000 megawatts, more than half of what this country generates from its aging nuclear fleet. Initiatives to turn this waste heat directly into electricity are already underway, and can be built on small scales that make it worthwhile for these industrial companies to invest in.

Being “green” is a badge worn with honor by companies and individuals alike. Just like consuming organic foods, it’s as much a yuppie status symbol as it is a lifestyle choice. At least it used to be. Venture capitalists are on the lookout for interesting green companies these days because there’s lots of money to be made by reducing energy consumption, cutting back greenhouse gas emissions, and generally doing more with less. From a very high, forward-thinking level, it seems bizarre that we haven’t been doing this right along: if economics is the study of human behavior in a world where there are limited resources but infinite demand, it makes sense that we would want to do more with less.

If it requires 50% less electricity to run an efficient datacenter, and 50% less gasoline to get from point A to point B, then that means we can house twice as many servers and end up with the same electric bill, and travel twice as far without burning any more gasoline. So every halving of the resources required to do something results in a net doubling of whatever you can do with that resource, all things being equal.

This model is easily applied to things like fuel efficiency and other commodity consumables, where small increases in efficiency result in immediate, apparent cost savings to an otherwise ignorant consumer. However there are other, less intuitive places to look where small savings aggregated across millions of people results in real macroeconomic benefit.

For example, there is a push right now to get rid of or improve “standby” modes for most electronic devices. This is what is widely considered the “off” position for most things, but in reality is actually the low-power mode wherein a device is not performing its primary function. The clock on the VCR and the microwave. The “breathing” the LED in your Macintosh computer does while it’s asleep. Your laser printer while it’s on standby waiting for a print job. Same for your fax machine.

A single device can suck up as much as 30W of electricity every 24 hours. Multiplied across all of the consumer electronics in your home, multiplied by the number of households in the United States, and you quickly realize that this is a boatload of wasted electricity. In fact, in the lifetime of a single electronic device, this savings is estimated to be $10. This is one of the reasons that President GW Bush directed the entire federal government to buy low-standby-power devices back in July of 2001 (PDF). Uncle Sam buys a lot of electronics. That means tens and possibly hundreds of millions of taxpayer dollars saved by one superficially insignificant initiative.

An economic case for being “green”

Economics, Science & Technology, , ,

If I were a venture capitalist today, I wouldn’t be looking at Internet startups. While the Internet is a sexy market and commands a lot of mindshare, I don’t think that it’s the future. We’re coming to the end of the Information Age. No, the problems uncovered by the Information Age aren’t solved. Search isn’t solved. Scientific computing as a whole is still quite nascent.

But we are gradually working our way out of this Age and into the next: the Renewables Age. Just like we’re still using what was developed during the Industrial Revolution, so too will we continue to use and develop the goods and services developed during this Information Age. So while computing and information management isn’t going anywhere, it will be superseded by bigger economic concerns. Namely, renewable energy.

I firmly believe that a few well-placed, relatively modest investments today can very probably yield absurd returns on investment sometime down the road. It would, however, be a very long-run type of play, and many VCs aren’t prepared to make an investment that won’t pay off within ten years.

With that in mind, I wrote the following as part of a larger essay for an economic history class about a week ago. What is interesting is that when I started the paper, I had no idea where I would end up. Like most Americans, I hadn’t thought about the “greening” of the economy at all. I didn’t have a conclusion in mind when I began. The final result was this, and I think I make a pretty good case for renewables and investment therein. At the very least, I have convinced myself, and I don’t really know how you can argue against it unless you’re talking timespans of less than ten years.

I’ve broken it up into a couple of shorter pieces because it’s simply too long to post as-is. No one would read it. Because it’s unedited, the beginning of each piece might feel a little jarring beginning on day 2.

Let me know what you think…

On fear, entrepreneurship, and wealth: Felix Dennis

Business, , ,

Felix Dennis who comes from humble beginnings:

An art college drop out, Dennis left home before his sixteenth birthday, and lived in a number of bedsits. Dennis started his career in publishing with Oz magazine, the Sixties counterculture magazine, initially as a successful seller, through which editor Richard Neville realized Dennis’ potential business acumen. Dennis had earlier contributed to a television discussion on the counterculture, which Oz reprinted; the first magazines Dennis sold had been Neville’s only available means of compensating him for using this material.

Oz was prosecuted for obscenity in 1971. All three editors were found guilty of corrupting children, and given jail terms with hard labour, although Dennis himself was given a shorter sentence because the judge, Justice Michael Argyle, considered Dennis “very much less intelligent” — and therefore less responsible — than his co-accused. It was such a cutting remark that it allegedly drove Dennis to create a business empire to prove the judge wrong.

Revenge empire? Interesting, if true.

Some quotes from this article, which somehow manages to be simultaneously annoying, enlightening, and heartening. Probably quite a bit like Dennis himself, if his writing is a window into who he is as a person.

The key, I think, is confidence. Confidence and an unshakeable belief it can be done and that you are the one to do it.

Tunnel vision helps. Being a bit of a shit helps. A thick skin helps. Stamina is crucial, as is a capacity to work so hard that your best friends mock you, your lovers despair and the rest of your acquaintances watch furtively from the sidelines, half in awe and half in contempt.

[…]

If you wish to be rich, however, you must grow a carapace. A mental armour. Not so thick as to blind you to well-constructed criticism and advice, especially from those you trust. Nor so thick as to cut you off from friends and family. But thick enough to shrug off the inevitable sniggering and malicious mockery that will follow your inevitable failures. Not to mention the poorly hidden envy that will accompany your eventual success.

Consider carefully this shortlist:

  • If you are unwilling to fail, sometimes publicly, and even catastrophically, you stand little chance of ever getting rich.
  • If you care what the neighbours think, you will never get rich.
  • If you cannot bear the thought of causing worry to your family, spouse or lover while you plough a lonely, dangerous road rather than taking the safe option of a regular job, you will never get rich.
  • If you have artistic inclinations and fear that the search for wealth will coarsen such talents, you will never get rich. (Because your fear, in this instance, is well justified.)
  • If you are not prepared to work longer hours than almost anyone you know, despite the jibes of colleagues and friends, you are unlikely to get rich.
  • If you cannot convince yourself that you are “good enough” to be rich, you will never get rich.
  • If you cannot treat your quest to get rich as a game, you will never be rich.
  • If you cannot face up to your fear of failure, you will never be rich.

On risk: Ann Winblad

Business,

Ann is the co-founder of Hummer Winblad Venture Partners which opened its doors in 1989. It was the first VC firm to focus exclusively on software. Since that time, 45 of its portfolio companies have been acquired or gone public. She began her career as a systems programmer at the Federal Reserve Bank. In 1976 Ann co-founded Open Systems, Inc., a top selling accounting software company, with a $500 investment. She operated Open Systems profitably for six years and then sold it for over $15 million.

$15 million in 1982 dollars is worth approximately $50 million today using GPD per capita measure, which is the appropriate metric for this kind of thing.

From page 299 of Founders at Work: Stories of Startups’ Early Days:

When I went there, it was the first real business experience I had — although I had had part time jobs. I’d never been in a corporation, and it felt so glamorous to have a cubicle. Minneapolis is a bright city. There’s the Nicollet Mall and you were right downtown in the city. It’s like getting a job in San Francisco.

But it just wasn’t inspiring. No one was chomping at the bit. I actually can’t remember — I knew I was going to quit, but I can’t remember the moment where I thought, “I’ll quit and start a company.” I still felt very empowered, like, “This isn’t this hard a job. This is a big job and I’ve already gotten promoted once in the first 3 months and I know I can earn money. I can always come back to this, so why don’t I break out?” So the three guys from the Federal Reserve that started the company with me — one guy did quit his job and the other two took a year sabbatical, just in case this didn’t work. They held on to the safety ring.

There were not a bunch of people saying, “Start a company, start a company. Let’s do this. Let’s build something from scratch.” It’s so long ago now that I just remember the general feeling that there was very little to risk. I was somehow already fully trained for anything that might confront me. Of course, all that is false; there’s a lot of risk and you are never fully equipped to… you just have to be very adaptable. It turned out that I was adaptable. I didn’t know that until I did that, but it was just a feeling of fearlessness. “What’s the risk? What will I have to lose? I’m sure I can do this.” It was not cockiness, just that moment you feel in your youthfulness that you are sort of empowered to achieve.

I think what does separate some entrepreneurs from other entrepreneurs is we’re not handwringers. We don’t worry about the unknown. We don’t really worry about the risk points ahead. As you get older and you get more experience, you train yourself to think ahead about the risk points versus just to take the next hill. But non-risk-takers and non-entrepreneurs would have really big headaches about this. They would need some level of comfort and safety.

That’s something that we look for in entrepreneurs — that they have the courage to do the job. That they’ll have the ability to judge the business situation. They’ll have the ability to lead people. They’ll have the ability to interact with the marketplace and to really build confidence into strategy.

On risk: Paul Graham

Business,

I’ve been doing a lot of reading lately, and today I was reading “Hiring is obsolete” by Paul Graham. I loved it, and the section on risk really stood out to me, and I’d like to highlight some specific bits.

So what you should invest in depends on how soon you need the money. If you’re young, you should take the riskiest investments you can find.

All this talk about investing may seem very theoretical. Most undergrads probably have more debts than assets. They may feel they have nothing to invest. But that’s not true: they have their time to invest, and the same rule about risk applies there. Your early twenties are exactly the time to take insane career risks.

The reason risk is always proportionate to reward is that market forces make it so. People will pay extra for stability. So if you choose stability– by buying bonds, or by going to work for a big company– it’s going to cost you.

Riskier career moves pay better on average, because there is less demand for them. Extreme choices like starting a startup are so frightening that most people won’t even try. So you don’t end up having as much competition as you might expect, considering the prizes at stake.

…

But it’s not necessarily a mistake to try something that has a 90% chance of failing, if you can afford the risk. Failing at 40, when you have a family to support, could be serious. But if you fail at 22, so what? If you try to start a startup right out of college and it tanks, you’ll end up at 23 broke and a lot smarter. Which, if you think about it, is roughly what you hope to get from a graduate program.

Even if your startup does tank, you won’t harm your prospects with employers. To make sure I asked some friends who work for big companies. I asked managers at Yahoo, Google, Amazon, Cisco and Microsoft how they’d feel about two candidates, both 24, with equal ability, one who’d tried to start a startup that tanked, and another who’d spent the two years since college working as a developer at a big company. Every one responded that they’d prefer the guy who’d tried to start his own company. Zod Nazem, who’s in charge of engineering at Yahoo, said:

I actually put more value on the guy with the failed startup. And you can quote me!

So there you have it. Want to get hired by Yahoo? Start your own company.

The entire essay is absolutely worth reading for anyone interested in starting their own business.

Benjamin Franklin on vaccination

Culture, Science & Technology, , , ,

Ben Franklin is one of my all-time favorite historical figures; there are few people who have been universally successful in all they’ve done: business, politics, science, and humanitarianism. Franklin was one of these, and he’s left a guidebook for those who wish to follow in his footsteps. (And really, how can you beat $2.50 for a brand-new book?)

I’ve been reading through it lately, and while it’s easy reading, it’s so chock-full of wisdom that I find it slow going. Lunchtimes and evenings find me with pencil in hand, underlining and annotating the bits that especially speak to me, and there are many.

I came across this paragraph, and I was astonished. With the anti-vaccination crazies gaining influence and mindshare, this earthy bit of common sense was a breath of fresh air, written in the 1700s by someone who knew a world without vaccines, and saw the devastation caused by these diseases — smallpox, polio, and many others — first-hand.

In 1736, I lost one of my sons, a fine boy of four years old, by smallpox, taken in the common way. I long regretted him bitterly and still regret that I had not given it to him by inoculation. This I mention for the sake of parents who omit that operation on the supposition that they should never forgive themselves if a child died under it, my example showing that the regret may be the same either way, and therefore that the safer should be chosen.

Simple and profound. Alas, I don’t think the anti-vaccination types will take his advice to heart, and we are all the poorer for it.

Custom Word medical spell check dictionary updated

Pharmacy, , ,

I have updated MeDic with a new version. 0.0.2 brings the dictionary from 41,009 words up to 66,239.

I have erred always on the side of accuracy, opting to omit a word when I couldn’t be sure that it was correct. Users have submitted their own additions, and I have folded them in, after verifying their accuracy to the best of my ability. Many of the words are quite obscure, as most of you can imagine.

Most recently, someone from Australia has created an Australian localization for the work, and I have added that to the page as well.

I think this is a better option for students and anyone else that wants a pretty comprehensive spell check word list, and doesn’t want to pay Stedman’s $100 to get one. This is also much more comprehensive than those $15 shareware dictionaries that you see floating around — many of which have spelling errors. (I know, I’ve looked at most of them.)

MeDic is, of course, freeware. And always will be. It’s also available for OpenOffice.org, for those of you who don’t use Word.

If you think it’s useful to you or someone you know, please bookmark it, Stumble it, or even throw me a link to the MeDic main page:

A history of debt in America

Culture, Economics,

While going through my RSS reader this morning, I came across one of JD’s daily links posts, and one of them was to A History of Debt in America. It’s quite a long article, but well worth reading. Unfortunately for people like me, reading large quantities of text on a screen gets to be painful after a few minutes.

I whipped up a quick PDF of all of the pages, and Tom, the author of the article, has graciously allowed me to post it here.

It’s 21 pages long, and will take you a little while to read it, but it’s worth the time.

PDF link.

If you enjoyed this, you may enjoy my post on how paying off debt is like folding laundry — a behavioral, as opposed to mathematical approach to paying off debt.

A unanimous triumph of common sense

Pharmacy, ,

Two posts ago:

Arthur Firstenberg says he is highly sensitive to certain types of electric fields, including wireless Internet and cell phones.

“I get chest pain and it doesn’t go away right away,” he said.

Firstenberg and dozens of other electro-sensitive people in Santa Fe claim that putting up Wi-Fi in public places is a violation of the Americans with Disabilities Act.

Result:

The City Council has unanimously approved a plan to provide wireless Internet service in libraries and other city buildings, over the objections of those who say they are electrically sensitive.

That doesn’t mean the legal wrangling is over, however.

Julie Tambourine, an advocate for the disabled and homeless, said after Wednesday’s meeting that the legal analysis was flawed, because it didn’t take into account those with diabetes, seizure disorders, respiratory ailments and other conditions that can be adversely affected by microwave radiation.

These idiots need to read up on the electromagnetic spectrum. Unless they’re going to sit in a lead box all day long with no visible light on a carefully controlled diet, they’re going to be exposed to all kinds of EM radiation, including gamma rays throughout their lifetimes. And even inside that theoretical lead box, there’s no guarantee of being radiation-free.

For further comic value, these people’s minds would explode if they had any idea of how many radio waves pass through their bodies each second. Theoretically, for physiologic purposes, 802.11b+g wi-fi signals (0.124-0.121m wavelength depending on channel) are no different than FM radio signals (~3m wavelength). Common sense would tell you that that’s pretty insignificant.

But since common sense is often wrong, we look to the actual evidence. And the evidence in favor of wifi radiation sensitivity just isn’t there.
