IngenuiTEA

On this blog I often complain about products that don’t work, or about whole segements of consumer products that I think are technologically impaired. Today however, I will take the opposite approach and recommend a product that I have come across that I think is really well designed and explain why.

The item is a tea infuser. For those unfamiliar with the term, it allows you to make one or two cups of tea using loose leaf tea without resorting to making an entire pot. Infusers come in many forms, often just a small perforated metal capsule either on a chain or built into a sort of spoon contraption. These have limitations though in that they keep the tea contained in a small space, not unlike a tea bag. The better infusers allow the tea to expand or unfold and release all the flavor.

Speaking of tea bags, you should know that tea processors commonly sort out the best tea for loose leaf packaging leaving the poorer quality tea for use in tea bags. Tea bags have their place but loose leaf tea is generally better.

So if you appreciate good tea, you may be interested in this little tea infuser. It is simple to use but very ingenious. It’s called the IngenuiTea infuser sold by Adagio.com.

You simply put the loose leaf tea inside, pour in the water for one or two cups, and let it steep for a couple of minutes. I stir it once or twice to get the full flavor of the tea.

Then comes the cool part. You place the whole thing on top of your mug and it depresses a valve in the bottom of the infuser and releases the tea through a strainer into your cup. When you lift it up, the flow stops. In case you’re wondering, the bottom of the infuser is designed to keep the valve from opening when you set it on a flat counter.

Then you simply dump the tea leaves into a trash can and rinse it out. I suspect that a lot more people would use loose leaf tea if they knew about this simple little device. To me it represents a class of products that eliminate an inconvenience and thereby open up the market to people who wouldn’t normally get involved.

The IngenuiTea is made from polycarbonate, not cheap styrene so it is built to last. Plus it comes with a removable filter that you can clean or replace. This one goes on my short list of elegant designs.

California Budget Crisis Replaces Police With iRobots

iRobot, the company that makes the “Roomba” and a floor cleaning robot called “Scooba” (both built at the toy factory in Guanzhou that I visited last year) is also building military robots designed to carry weapons. Recently iRobot signed a contract to add tasers to their industrial/military robots. This is all happening in a climate of significant military interest in funding the development of tactical robots designed to “Hunt Down Uncooperative Humans.” These will be developed initially for military use. However, given the speed at which technology enters our culture, I expect to see robots replace expensive police very soon.

If shortly you see hundreds of bug-like creatures patrolling the streets of Santa Monica in the evening, I suggest you make every effort to suppress your girlfriend’s impulse to insult them. These creatures probably won’t be programmed with highly evolved ethics routines and you may find yourself either seriously incapacited or worse. Let’s hope they don’t also contract with Microsoft to write the software. Maybe by version 4.0 they will have gotten all the bugs out.

Be afraid, be very afraid.

Why Can't My TV Fix Itself ?

We all know about the Geek Squad, the highly successful subsidiary of Best Buy started in 1994 to help you solve your pesky tech installation and service problems.

The idea is great and sorely needed by all of us who cannot figure out how to get viruses off our computers or how to set up that new HD flat screen and get the damn sound to come through.

But the service doesn’t come cheap considering how long it normally takes them. If you’ve ever had one of their “secret agents” out to your house, you probably experienced something like the following:

• You make the appointment
• They come out in a day or two
• They arrive and you explain the problem.
• They poke around behind your TV, move a cable, pick up the remote, change a setting, and they’re done.
• You pay them $100 for their travel time and the 12 minutes they were actually working on your problem.
• They leave
• You feel stupid

So what’s the alternative?

For today, the alternative is to figure out how to do it yourself by reading the manual or going online and spending time searching through forums for the same problem, or, and this is the best alternative from your perspective, call upon your built-in tech support agent. That would be your spouse or son-in-law or teenage daughter.

But what about tomorrow? Will it get to the point where you have to set up a yearly contract with the Geek Squad? Will we all develop a deep dislike of anyone with an Indian accent? Will geeks finally gain superiority over the technologically-impaired on Harmony.com? I don’t think so.

Call me an optimist, but I really believe that over time in spite of the rapidly increasing complexity of technology, the problems we face will get better. The premise for this non-intuitive idea is that as memory continues to get cheaper and embedded computing power continues to grow rapidly in everything from your toaster oven to your satellite receiver, these things will start to fix themselves. Hey, it could happen!

By fix themselves, I mean that they will either 1) walk you through a troubleshooting and repair process on their control panel, or 2) go online themselves and, with the help of the mother ship, fix themselves without you ever knowing.

It sounds like science fiction right now but believe it, the market will force the issue. Billions of dollars are being spent by high tech companies to handle all the service calls that their poorly integrated products create. The best example for me at the moment is home theater. With the advent of HD and flat screens, the whole cabling and signal management problem has gotten much more complicated. Some receivers pass through the audio, some do not. As the commercial says, you need an engineering degree to figure it out.

Computers also have a long way to go before they can protect themselves from getting messed up thanks to Microsoft. Automobiles will also diagnose themselves and hopefully, once they become all electric when the internal combustion engine is finally retired, become easier to diagnose and repair.

Of course, before long your home computer named “Hal” will develop an intimate relationship with your home theater and your car and your pool equipment and your toaster oven.

That’s kind of a scary thought actually.

A Reasoned Approach to Global Warming

As someone who was trained in school to appreciate the scientific method, I naturally question issues that are promoted with extreme passion in the media and presented in such a way that you are expected to just accept the premise without question. The conclusion that human-produced CO2 is the overwhelming cause of global warming clearly falls in this category for me.

In the first place, a significant number of noted scientists and climatologists believe that anthropogenic CO2 is at most a minor part of the entire climate picture. Some argue that they are actually in the majority (see the link at the end of this post), proving that there is no consensus whatsoever on this important fact. This however, does not stop environmentalists from using any means to get our attention, including resorting to gross exaggeration or blatant lies.

Secondly, there are dozens and dozens of mathematical models one can choose from to predict the effects of global warming over the next century. The problem with all of them is that you have to assume a whole host of values for most of the factors that make up the incredibly complex global weather system. By manipulating these variables in the models, you can literally generate any scenario that supports your position.

I often listen to NPR in the afternoon and a couple days ago they interviewed scientists on how much the sea level is expected to rise over the next 100 years. The estimates range from 6 inches to 10 feet and the responsible scientists openly admit that they really have no idea how fast glaciers will melt over that period of time, nor are they certain what the temperatures will be in those regions over such a long period. But again, there are some who, simply to get attention, will loudly and with resounding certainty claim it is going to be 10 feet.

Unfortunately, our news media thrives on bad news and absolutely loves to hear these kinds of wild irresponsible predictions. All they have to do is preface their news bite with “scientists claim” or “a new study shows that...” bla bla bla and we tend to believe it.

The unimaginable complexity of global weather is exactly why scientists cannot predict a hurricane more than about 2 weeks out and yet no one seems to question the pundits that predict the average temperature of the entire planet 5,200 weeks into the future! Unfortunately, in the current social climate of green this and green that, scientists who point out the folly in these predictions are effectively silenced by denying publication or having their funding cut back.
It’s not only the scientists who are being silenced. Politicians are even more inclined to take the safe position. Those few who are brave enough to take a stand for reason are getting rarer and rarer. I ran across one speech that is to me a breath of fresh air coming from an elected official. Tom McClintock, State Senator in California, early this year spoke about the teaching of Global Warming in our schools. Note the comments about the peer reviews of CO2 effects and the review of Al Gore’s presentation by the British.

Tom’s Speech on Global Warming Curriculum

Ask yourself this. What if we totally screw up our economy trying to “stop global warming” only to discover in 5 or 10 years that human produced CO2 really has very little effect on the outcome? How many people will lose their jobs because businesses cannot continue to make a profit under the new “green laws?” How much will the cars of the future cost that meet all the proposed environmental laws?

Important Note: The number of adherents to a position has no relation to its truth. Thousands of years of science versus religion has proven this over and over. We need to encourage debate on this issue and not allow the green movement to turn into a belief system that ignores science.

Electronic Books - Ready For Prime Time

I sent my friend Eric a recent ad from Amazon about the Kindle electronic book.

His reply was “Solution for a problem that didn’t exist?”

I totally understand his reaction and have been on the same page for many years (sorry, couldn't resist the pun). But I suspect this is probably like the DVR, something you didn't think you needed until you tried it. I have a DVR that I got through Dish Network and I love it. I set it to record the shows that I happen to like, and it records all of them over the next week or so, or just the new ones, depending on how I set it. Then I watch them when I have time, without the commercials. I often wonder how I got along without it.

So, although I have resisted the urge to buy an electronic book due to the high price and the hard to read screens, I am seriously thinking about it now with the promise of electronic paper. After reading some of the user feedback, I'm expecting the next version of the Kindle to have more memory, better ergonomics and lower cost.

It's like digital encyclopedias versus paper ones. As e-books evolve, you will be able to search a document, highlight a paragraph, tag it, save it, and email it to friends just like you do on a PC, only in this case it will be in a form factor that is much more comfortable to read than sitting at a desk staring at a monitor, i.e. on a bus or on your balcony overlooking the Swiss alps. The Kindle is networked like a cellphone, not WiFi, so it should work almost anywhere.

Eventually, the DRM legal issues will get worked out so it is not so restrictive, and you can share passages with friends or resell your copy. Maybe they will even get to the point where the creative guy gets the bulk of the royalties, and the middle man just gets a small percentage.

I still prefer the character and feel of a real book and the fact that you don't need batteries, but at some point the two curves will cross and electronic books will become "better than cutting down trees" for many purposes. For example, my kids had to lug 30 lbs of textbooks back and forth between school and home every day. You could take your back out reaching across the car seat to grab one of those backpacks. That's at least one good argument right there.

RFID License Plates

I think it’s high time we moved away from the antiquated low tech way we have of identifying vehicles on the road. I’m talking about the dumb metal plate with letters and numbers embossed on it that we call tags or plates. We now have the technology today to do much better.

As has been done in the UK and other places, it is time we switched to RFID license plates. The new plate would be made of nylon or some very tough plastic composite material with a chip embedded in it. The chip would be programmed with the VIN number of the vehicle, the make, model, year built, registered owner, etc. The RFID chip would probably need to be passive with a large antenna so that it doesn't need to be connected electrically to the vehicle.

Benefits:

• Ability to confirm that the plate goes with the vehicle just by matching the make and model of the car.
• Ability for police and parking enforcement to accurately identify the registration and eliminate errors of writing down the tag number or errors in radioing in the numbers. This is especially useful with vanity plates that have some arcane combination of symbols and letters and numbers that are easy to misinterpret.
• Faster way to ID a vehicle electronically. The officer would just aim a reader at the car and the info would pop up on his screen, no need to type it in on a computer or call it in.
• Ability to scan vehicles at full speed at checkpoints
• Better control of vehicles at the borders
• Cars that run red lights would be accurately identified – no need for photographs that are hard to read during the daytime and almost useless at night.
• Automated speed traps. A combination of radar and RFID readers would be incontrovertible evidence of speeders.

You’re may wonder if I work for the justice department. Actually no, but I am an advocate for better traffic control. I am convinced that it is the wild guy on the freeways that sets up situations where massive collisions occur. We all notice the guy who is weaving all over the place, passing around traffic at 85 in the slow lane, constantly changing lanes in an attempt to go 20 or 30 mph faster than the prevailing traffic. He is the guy who cuts in front of people scaring them into over reacting and causing accidents. This is often the guy who leaves dead people in his wake, unaware of the consequences of his reckless driving. Why does he get away with it? Because he enjoys effective anonymity on the road. Unless there is a cop right there, he is free to drive any way he wants with impunity.

I watched one of these guys on the way to work a few months ago. He was totally out of control. He was making such drastic lane changes in his truck that you could see the whole vehicle tilt left and right as he was careening around other cars. It wondered if he was on drugs. When you see such a blatantly unsafe driver you instantly think “where is a cop when you need one.”

So, consider the impact on people’s driving habits if they knew that their speed or their driving was being constantly monitored as they go through every intersection. The RFID readers and radar detectors can be small enough to be unnoticeable, possibly buried in the pavement like the traffic sensors. Inconspicuous enough that you start to believe that they could be anywhere. Soon you pay more attention to your speed and you drive more conservatively knowing that the police have the advantage of technology. It is as if you amplified the effect of people driving in the vicinity of police cars where they take it easy and watch their driving.

Another thing to consider is our ever growing traffic congestion. As drivers pay more attention to speed and avoid reckless actions, there will be less stress on the road, fewer lane changes, which translates to less congestion, less road rage, an easier drive to work. Small changes in our driving habits would also save gasoline. A more conservative foot on the gas pedal will save a huge amount of energy across the entire population.

It is time to move away from the no-tech license plate and encourage people to be more responsible. A little psychology can save energy and so many lives.

To those who counter with the argument that RFID is somehow an invasion of privacy, my response is that if you are one of the people running red lights and doing 50 in a 35 zone, you have made the conscious decision to ignore other people's safety and deserve to be caught. RFID license plates are just a more effective way to make drivers accountable for their actions and in the process, make the roads safer.

Assumptions

A couple of weeks ago a friend suggested I read a book by don Miguel Ruiz called “The Four Agreements.” It is a simple book with a powerful message. Briefly, the four principles that he presents are the following. I’ve re-worded them slightly for my own use.

1. Be Honest in Everything You Do - Your character is your most valuable possesion and integrity is its foundation. Protect it as you would your life. Your words can have powerful impact. Avoid speaking against yourself or others. Use the power of your word in the direction of truth and love.

2. Don't Take Things Personally - What others say and do is a projection of their own reality, their own dream. Believe in yourself. When you are immune to the opinions and actions of others, you won't be the victim of needless suffering.

3. Don't Make Assumptions - Find the courage to ask questions and to express what you really want. Communicate with others as clearly as you can to avoid misunderstandings, sadness and drama. Don’t judge people before you know them.

4. Always Do Your Best - Your best is going to change from moment to moment; it will be different when you are healthy as opposed to sick. As the years pass by new skills will emerge and other skills will fade. Under any circumstance, simply do your best, and you will avoid self-judgment, self-abuse and regret.

These simple ideas can change your life if you have the will to follow them. Today I discovered a small example of agreement number 3.

During my morning walk as I was heading back toward home, I noticed a trash truck idling on the other side of the street up ahead with no one in it. I continued walking and still didn’t see the driver, but as I got closer I noticed him on my side of the street in a driveway. He was talking to an old lady standing there holding onto a walker. They were smiling like they knew each other and chatting away. As I passed, he looked at me and I smiled and nodded to them, and the man returned a friendly wave and a nod. The woman was busy talking and didn’t pay attention to me but she seemed like a nice lady.

The reason I mention this is the house. On several occasions I have called it the ugliest house in the neighborhood. It is on a corner lot and is very foreboding looking, old and dark with a turrett on the front giving it an almost gothic feel. There was a small guest house in the back and an unusual garage.It was a little over one car width wide but very tall, the rollup door must have been 12 feet high. I speculated that it was built for a boat but there was no evidence of other nautical things around, very unusual. The whole property was creepy and somehow malevolent looking because the walls were dark red brick, almost brown, and the roof was dark spanish tile and if I was 7 years old and someone told me that a monster lived in the garage in the back, I would have believed him. The entire front and side yard is dark green ivy; no flowers, no toys sitting around, no newspapers on the walk, no sign that any humans lived there. I imagined some mean old reclusive man watching from behind the curtains.

So today as I walked past this nice old lady standing there supporting herself with a walker talking to the trash man, my concept of this house totally changed. My assumption was totally wrong. In 10 seconds I formed a totally new concept of a nice little old lady living there alone, unable to do much except check the mail and chat with the trash man.

I think I may knock on her door someday and ask her if she needs any help around the house. Who knows, she may invite me in for tea; the inside may be totally different than the outside. Like most people.

Instruction Manuals

I just spent 20 minutes outside in my driveway sweating in the front seat of my wife’s car trying to set the damn clock on her new car stereo. Unbelievable!!! Sometimes I can’t believe how little we have progressed toward making technology easy to use. It feels like we are going backwards in time.

This is from an engineer with the manual open in front of him. I did exactly what they tell you to do and was getting nowhere. Finally after trying countless different ways to get to the clock setting menu, by sheer chance I found the right arcane combination of button presses and tilting the “multi-control” up down left right, push in, turn right, turn left, etc. etc. etc. I discovered that they left out a few critical steps before you start with the sequence in the book and they never tell you how to exit the process. Unbelievable!

When I say we are going backward, this is what I mean: In my 12-year-old suburban, I have a stereo that still works great. It is one of the larger format GM style units which allows for buttons that are actually readable without leaning over to get close to the thing – even at night. To set the clock there are two small inconspicuous buttons marked HR and MIN. All you need to do to set the clock is hold down either one of these for a few seconds and it automatically goes into the clock setting mode. You then press the appropriate button until the display reads what you want.

No need to worry about AM or PM, they assume that you have the IQ to know whether it is 8 in the morning versus 8 at night. When you are done, you leave it alone for about 5 seconds and it reverts to normal mode and the time is set. When daylight savings time comes around, I can change the hour while I’m sitting at a stoplight – it takes less than 10 seconds. No manual required, no 15 step process, I just reach over and voila’ it’s done.

I have probably set over fifty different digital clocks in my lifetime and none were as non-intuitive as this Pioneer DEH-P30001B unit. Some are a little more complicated than the one in my Suburban, but none come anywhere close to this %$#@** Pioneer unit. Just so the people at Pioneer don’t think I’m ganging up on them, I had a Sony car stereo a while back that was just as bad, except the instructions were better. The problem with the Sony one was the clock would not keep good time so I had to reset it every month or two. After about 4 times I was eventually able to go through the multi-step process without hunting for the manual. Another fine piece of engineering designed by computer nerds with no regard for ergonomics.

By the way, this stereo has a 51 page operation manual crammed to the gills with instructions on how to access the hundreds of features that this fine stereo can handle. Impressive, but good luck remembering how to access most of them unless you have the infinite patience to sit in your driveway with the book and do a lot of trial and error. Please refer to a previous post about the application of intuitive design principles in complex electronics. Nice work Pioneer.

Products That Don't Suck

Call me pretentious but I want to start a trend. The trend I want to start is for all you designers of electronic items to pay more attention to how the new customer sees your product. Test the product on neophytes and then redesign the product and retest ad infinitum until you are satisfied that everyone gets the value from your product that you are promising.

After many frustrating experiences with digital cameras and kitchen appliances, stereo equipment, cars, etc., I'm convinced that companies do not do enough prototype testing. Here are my suggestions:

• Develop your product so that 90% of your customers do NOT need a user manual to do everything they expect it to do.
• Always (if possible), incorporate an interactive user guide into the product to explain the more advanced functions.
• If there is more than one element, design the packaging to explain exactly what each part is for so they don’t need a manual. If necessary, provide a separate assembly guide that goes step by step GRAPHICALLY.

Stated another way, design your product so it is totally intuitive to operate for all the basic functions, AND so that it interactively guides the customer toward mastering the more advanced functions AND is a piece of cake to put together and/or set up.

Seems like a reasonable goal, right?

Not simple at all. In fact, it adds a tremendous amount of work to the design process. But here’s the thing. That is where the time should be spent, not by the thousands or millions of people who purchase the product trying to figure out how to work it. The whole idea of paper instructions is rapidly being replaced by some sort of digital media anyway. Since memory is now very cheap, why not incorporate the user guide into the product itself and design it to be interactive?

I’m not talking about just loading images of a standard formatted user manual into your digital camera. I’m talking about an AI interface where the camera judges what you are trying to do and asks you relevant questions to lead you to the answer quickly. Cameras are an excellent example of complexity gone wild. Even geeks need help here.

The critical thing is that the controls are designed to make the basic functions simple and intuitive so your customer can immediately start using the camera or GPS unit or DVR. You want them to feel a sense of accomplishment and validation for making the purchase.

Then you want them to become your evangelists, especially the ones who are inclined to submit articles to technology websites where people increasingly go to before making a buying decision. And that is the key to taking the product to the tipping point - word of mouth is more powerful than any traditional ad campaign in this internet enabled society.

But as someone once said, word of mouth marketing is only a good idea if your product doesn’t suck. I’m counting on the instant feedback aspect of the internet to fuel the trend towards intuitive design. It could happen.

Thank God For High Priced Gasoline

With all the renewed interest in PV technology (photovoltaic) I am revisiting some thoughts I’ve had over the years about the viability of putting one of these solar panels on my roof. After some brief checking, it seems that the price of residential systems for a medium size tract home is still too high for the average family and the payoff would take something like 15-20 years even if you live in the sunbelt (as I do). But even worse, this is a system that may only deliver 50% of your electricity needs.

Some firmly believe that massive utility-based systems stationed outside of town are the answer. Living in the middle of Los Angeles, I don’t think that is necessarily the best solution, mainly due to the huge energy demands of a metropolitan area that extends for a hundred miles.

Instead, I prefer the distributed approach, kind of like PCs versus mainframes. Of course, this requires the development of cheap PV systems that pay for themselves in 3-5 years. My opinion is that the tipping point for PV installations will be when inexpensive solar roofing tiles come on the market. This is not at all unrealistic and there are several companies tackling that problem as we speak.

There are a few other things happening that will make PV installations even more attractive:

• The cost of electricity will continue to go up, probably at an accelerated rate as demand increases and production costs increase.
• The emergence of electric vehicles that you charge up at home is not too far off. This is a whole subject in itself. I predict that in many communities more and more people will buy electric golf cart type vehicles for short trips to the market.
• The steady growth of electronic gadgets in our homes will continue unabated.

All these things and more will make the ability to capture free energy from your roof increasingly attractive. At some point, it will become a critical selling point when you go to purchase a house. No PV system = no sale.

Although I continue to believe that nuclear power should be a much bigger player in our energy plan (you need to generate electricity when the sun is not shining !!!), I just don’t see it expanding much until we can economically blast all of our nuclear waste off to Venus. Of course then there will immediately materialize an environmental group lobbying to save the environment of Venus.

The other major (clean) options besides PV are wind, wave energy, hydroelectric, and geothermal. I just came back from China so coal is definitely not on my list unless we are successful in converting it to a clean burning alternative. Of these other options, the largest potential source of energy is clearly solar and thankfully there are a whole host of companies working to develop inexpensive solutions to capturing solar energy.

We can thank the price of gasoline for finally creating the incentive to work on this problem.

Journey With My Nano

Around October 2006 I had an attack of sciatica down my left leg, a common byproduct of sitting at a desk for 10-12 hours a day. For anyone unfamiliar, it’s usually caused by a pinched or inflamed nerve that can get so bad it gives you pain 24 hours a day. For whatever reason, my pain was in my left hip radiating down my thigh. Readjusting my postion sometimes helped for a while but that was working less and less. I even had pain when I was driving.

So rather than getting hooked on Vicodin or Ibuprofen, I started walking 2 miles every other morning. I live in a hilly neighborhood with quiet tree-lined streets, a really pleasant place to walk. Not only is it a nice environment with no traffic, but it is uphill all the way to the half way point which is perfect for my purposes. I get a pretty good workout if I push myself to do it in 30 minutes and I suffer no ill effects at all. So after a couple of weeks, the pain was gone and hasn’t come back and I’m sure the walking has improved my general health.

The thing that really makes it work for me is my iPod. First I timed exactly how long it took to get to the half way point and then back home. Then I selected songs that had a good tempo that would push me on the uphill portion. The trick was to select the songs so that I would arrive at the top of the hill just when a particular song was starting. On my walk it is a place where you turn the corner and are facing east just as the sun is rising; it’s a kind of spiritual point for me.

So, for that next song I chose The Prayer, sung by Cantor Alisa Pomerantz and David Propis. There is something very personl about that particular rendition of “The Prayer.” I like the ones by Celine Dion and Andrea Bocelli or Josh Groban but I guess it is the Hebrew in this one that makes me think of my daughter Amy – it makes coming to the top of the hill and walking toward the sunrise a very special moment in my day.

So get yourself an iPod, load some songs into it and set up a playlist that motivates you to get off your butt and enjoy some fresh air. Believe me, it is not only good for the body but it is like a form of meditation – it fuels the soul too.

One Armed Bandits

Maybe we should rename faucets like the one in the picture “One Armed Bandits.” Think about it. Every time you turn on the faucet to wash off your hands or rinse out a glass before putting it in the dishwasher, you are drawing hot water from your water heater half way across the house. That hot water travels ten or twenty feet or all the way to your faucet and mixes with the cold water because all such faucets are designed so that the arm normally sits in the center, mixing 50% hot and 50% cold water. People don’t even think about just swinging it to the cold water side when they do something quick like washing their hands off. They just lift it straight up.

I just did a quick unscientific test. I washed my hands in the kitchen and measured how much water I used: 2 quarts. That means everytime you wash your hands you waste the energy to heat 1 quart of water. Multiply that by however many million such faucets there are installed in kitchens or bathrooms all over the world, then by the number of times people turn on the water when they don’t need hot water. I’ll leave it to someone else who has the time to convert that to wasted BTUs but it is a whole trainload of wasted energy every day.

The solution to this does not necessarily mean going back to the old style faucet with a hot and cold valves side by side like you commonly see in bathrooms. A better solution that would be more popular is to design a faucet where the most natural way to turn it on is when it is drawing only cold water. Some newer style single hole faucets have two valves, one for the pressure and one for the temperature. Some of them are very awkward, but some are excellent.

I offer this as a whole new episode of “Living With Ed.”
