A Very Dirty, Clean Car

I've owned more than one truck in my lifetime and I currently own one of the least efficient trucks that a consumer can, in the US.  I like utility.  Trucks are definitely not considered to be very efficient, unless they are used for moving are objects or numbers of people.

The measure of a vehicle's "greenness" is factor of how efficient it is.  It would be very inefficient to drive a large truck with no cargo and only one occupant (the driver). The phrase "being green" is to state about how little oxidized carbon is put into the air by the operation of the vehicle.  Greenness is Cleanness.

By contrast to the truck, the Smart ED is VERY green.  It was, in fact, determined to be most green car on the road by the American Council for an Energy-Efficient Economy (ACEEE) in 2014.   The Smart ForTwo ED has an exceptionally high MPGe (Miles Per Gallon equivalent) rating of 107 average (92 hwy, 122 city).  If you were to convert it's range to an equivalent gas tank, it would be roughly 0.66 gallons.

So why is this such a dirty car, if it has been verified to be very green and thereby clean?

One of the things that drivers (most people in the US) do on a regular basis, is to visit a fueling station. Of course electric car drivers do this as well, but there is one major difference between fueling stations for electric and gasoline.   An industry has grown up around the "Gas Station".  It's not just a place to pump gas into the gas tank any more.

Gas stations are often mini-markets in additional fueling stations, and some are also car washes. It is possible to use a squeegee to clean the windows of your vehicle.  Some stations have LCD monitors embedded atop the pump to run news and advertisements.  The fueling station is nearly a destination.

Nearly 100% of the time I refuel my Smart ED at home.  And although I could quite easily vacuum and wash the vehicle, I had not yet trained myself to do that on a regular basis.   Sadly, I have only done it once in the nine months that I have owned my Smart ED.   And my wife and some friends have made note of the fact that the floor and seats are in need of cleaning.

I have once visited a gas station to use the squeegee and refill the tires, but I do feel a tad unwelcome.  Even if I wanted to get gasoline, I would need a sealed container or a proper gas tank to legally purchase it.

So it seems that at least until electrical fueling stations become popular, I must change my ways and actually clean my car at home.  Or at least hope that the purveyor of the fueling station doesn't care that I use the facilities without paying for the fuel.

Under foot

For those who are aware, the Smart Fortwo is the smallest production vehicle in the US market.   Outside of the Twizzy in the UK and the Tata Nano in India, it might be the smallest in the world.  It is a tiny car and with it comes both good and bad aspects.  In this episode we explore the color of the Smart ForTwo and how it affects the car.

It's been said that certain colors are more noticeable than others.  Some colors are easy to be seen, others are not.  A study in Australia at Monash University pointed out that of all the colors (or lack there of) black is the worst, followed closely by grey, and then silver for likelihood of crashes versus white colored vehicles. The report used "white" as the standard by which all vehicle colors were compared as if to say that white is the easiest to see. Of course the study included comparisons in daylight, dusk, and nighttime.  Dusk it seems holds a particular spite for black.

Personally, I've experienced more than one presumptuous maneuver when driving my Smart, where the other driver doesn't seem to grasp that my car is either real or relative.  Fortunately, with its size, the Smart Fortwo has an excellent capacity move or stop quickly if needed and I've yet to trade paint with anyone.

I am keenly aware of how much I tend to miss vehicles that are much larger and not black, and so I decided on white for my car.  I realize that it's not always possible to get the color of car that you would most like, when purchasing used (sometimes also new).  But I cannot understand why anyone would deliberately purchase or alter the color of their car to black, outside of the precise desire to go unnoticed.

Although I do not have the statistics on the most preferred color in a Smart Fortwo.  I did notice that most of the cars on the lot where I bought mine were black.  Either that was because they were not preferred or because many people seek the color.  I've also noticed, back a few years when searching for a truck, that most of those on the market were also black.  These two observations have lead me to the idea that either black vehicles are unwanted or they are in high demand.  In either case they are still the most likely to be in a collision.

In the United States of America, as far as I know, there is no mandate on what color or size a production car must be or not be.  However, I so chose to make my small car as noticeable as I can, barring painting a sparkling, fluorescent share of pink. I realize that I have no control over the actions of others but I can at least drive Smart-ly and safely.

Dual Carbon Batteries, what next?

The announcement of the Dual Carbon battery got me thinking about power storage in electric cars.  There are two lines of thinking in this area, (1) faster charging (2) greater range.  At the moment most people are concerned about the range, but charging or refueling is also a concern.

The dual carbon battery promises much and, at least supposedly, can deliver.  It should be noted here that the dual carbon battery is not all new.  Many battery chemistry types have been, in theory, possible for decades, but there was not much time spend on research.  A company called Power Japan Plus is the one to announce a functional dual carbon battery last week, that is making headlines.

Current battery technologies like Nickel-Metal Hydride (NiMH) and Lithium Iron Phosphate (LiFePHO4) have provided a solid example of what is possible with battery technology.  But there is always room for improvement.

Gasoline has ruled the automobile industry for 100 years because of it's energy capacity.  Although gasoline requires that it be burned to harness the energy, that has not slowed its use. We could have been using nuclear power to the same end, creating massive quantities of radioactive waste rather than pouring carbon monoxide into the atmosphere, but gasoline was available first.

We don't use nuclear energy as much because of its toxic waste products.  Even batteries have some toxic materials in them, until now.  However, the dual carbon battery is made of 90% recyclable materials and offers many other features that are not found in Lithium Ion batteries.   By comparison the LiFe battery does the following better than any of its predecessors...

• It doesn't get hot or explode when in operation (lithium is volatile)
• It's made of carbon, which is quite plentiful (compared to lithium which is not)
• It charges much faster than lithium, about 20x faster
• It can be recharged more times that any other battery chemistry

So Dual Carbon solves problem number one, and by chance resolves a few other issues.  It might just be the solution that arrives sooner than lithium air and in the long-run is cleaner. 

But the revelation of Lithium Air and now Dual Carbon, leads me to wonder, what's next?  Is there some super material out there that we've yet to find that will be more energy dense than gasoline, clean, fast to recharge, and recyclable?  Based on these two recent technologies, it's my guess that there is something better.

Every Day is a 'Spare the Air' day in an Electric Car

When you hang around a bunch of electric car enthusiasts, you get a great deal of feedback from like-minded people.  Yesterday, I joined my fellow enthusiasts for the first of many Earth Day events in the month of April.  The members of the Electric Auto Association of Silicon Valley have attended most of these Earth Day events for many years. It was a great day to show the public the advantages of driving electric.

It was only in 2008 when I joined the Electric Auto Association, but the club had been official for 41 years at that time.  Back in 1967 the symposium of people who were meeting for the sake of electric vehicles decided to form what today is a club of over 2000 members through the United States.  And although it has held on this long, it was no easy ride.

At the turn of the last century (early 1900's) one-third of all horseless carriages were electric. But the advent of the internal combustion engine would soon curb the progress of the electric car. It was primarily a range problem and, in the nearly 100 years to following the range of electric vehicles did not improve.

Air Quality

Today however, the message of the electric car is finally making headway.  One of the slogans of the EAA is

"Every Day is a 'Spare the Air' day in an Electric Car

It was very apparent in the 1950's and 1960's that automobile pollution was causing problems.  My dad told me of the Smog Days that he experience growing up in Southern California at that time.  He lived in the Foothills North West of Los Angeles where there were days when the mountains were hidden by the pollution.  There were predictions that any child born between 1968 and 1980 would have life-long respiratory problems due to the smog.

Even today we are still concerned with the quality of the air, as rightly so.  It's not just a nice feeling to know that you're driving a vehicle that produces no emissions, it's a direct correlation. No emissions, breathe easier.

Notable Concerns

Of course there are still arguments about how the energy is produced that will run the electric car.  And there are concerns about usage and power balance in the grid.  It is important to know where your power comes from and what it is used for most often.

Where electric cars use electricity directly, in California at least, more than 50% of electrical power is produced from renewable sources and natural gas.  It takes electricity to extract, refine, ship, and pump gasoline.  And there is, at least for now, no way to convert sunlight into gasoline.

Granted, the manufacture of batteries is quite complex and still very expensive, but no less environmentally costly that all the fluids and needed to produce the current internal combustion engine and peripherals.

Conclusion

Assuming (broadly) that the production and recycling costs, be it environmental or monetary, of each type of car is effectively equivalent, the one trouble that we still face is at the tailpipe.  We're still making progress in education and the more people we can help to learn about electric cars, the better decisions can be made for the future.  It's up to you to decide how to get from point A to point B. Will it be clean and quiet or loud and dirty?

The Greenest Car

This week saw the American Counsel for an Energy-Efficient Economy (ACEEE) announce their findings for the "most Green" vehicles.  And do you want to know who came out on top?  Yes, the Smart ForTwo Electric Drive.  With a Green Score of 59 it bested even the Toyota Prius C (57), Prius (55),  and the Prius Plug-in hybrid (55).

But what does the ACEEE mean by "Greenest" vehicle?  What do they measure and is it all empirical?

The ACEEE takes many factors into consideration when attempting to determine a proper score for any vehicle.  In the past, the average vehicle score for the vehicles that are conducive to cleaner driving, often receive a score around 37.  Where as the "meaner" vehicles, like trucks, SUVs, and vans tends to be closer to 17 on average.  The total score is ranked out of a possible 100 points,

Although most of the Toyota Prius line is in the top 10 Greenest, and the Prius C was the champion last year, a score of 59 has not yet been awarded to any vehicle, until now. This year the rating system has some added changes that may have accounted for the fact that the ED made the top of the list.  Here's the list

• Updates to in-use emissions factors for methane (CH4) and nitrous oxide (N2O) 
• Changes to the methodology for estimating fuel economy for 2b trucks 
• Updates to evaporative emission estimates 
• Rating vehicles with LEV III tailpipe emission standards 
• Updates to upstream emission factors for gasoline, diesel, and CNG 

The primary concern seems to be tailpipe emissions, but materials used in manufacturing the vehicle are also considered.  If you read the comments on the blogs that have reported on this announcement, you may have noticed the dire skepticism and regular arguments that continue to pop-up.  The ACEEE address these issues directly in each vehicle.

Although no vehicle has crested 60 out of a possible 100 on the ACEEE index, it's clearly important to note that whatever Smart is doing in the construction and endgame for the ED, it is good.  I will definitely toot the horn of my Smart ED in saying that it's not just environmentally safe, but also the most affordable battery electric vehicle available in the US.
