Is Car Exhaust The Only Real Problem Here?
Any of us who have flown into Los Angeles, Phoenix, or any other large city with large numbers of vehicles on the road, we know what the dirty are looks like. We also know that much of this is pollutants from cars on the road.
Currently there's over 247 vehicles on the roads in the United States so it is no wonder that the smog continues to be an issue. Of those, about 133,000 are electric capable. That may sound like a good start, but do we take into consideration the pollutants produced in making the electric to run these cars?
This is such a vicious circle. One depressing thought to me was the lack of information on numbers
of vehicles that could run, even short distances, on solar panels. I will continue to do research on this subject and share what I find, when I find some solid information. After all, if you can run a boat on panels, so could you a small vehicle. Right?
By now you probably think that what is bothering me is the pollution caused by vehicles or the lack of solar powered cars. But that isn't what got me started. Just some of what bothers me, often. What I am having an issue with is something I saw on the news last week. The issue - underground fuel storage tanks.
I live in Arizona, a state with plenty of sunshine to support solar energy. In a recent state audit it was revealed that more than half of the almost 4,000 tanks are reaching or have passed their 30 year life expectancy. The audit, performed by the Arizona Auditor General's Office, reported that 901 underground fuel storage tanks are older than 30 years old and another 2,935 are between 20 and 30 years old. All of these tanks are at risk of leaking gasoline, diesel fuel and other chemicals into the soil and ground water. A spokes person from the Arizona Department of Environmental Quality stated that they are aware of this situation and are taking it very seriously. I do sort of wonder just what that means. I would be willing to be that everyone in that department, and anyone who has access to this information, has checked to make sure that the possible leaking tanks are not effecting their personal water source.
This isn't meant to be a bitch session towards any government agency but it is meant to bring to the attention of anyone who is interested the fact that this entire problem goes right back to the beginning of this post.
Fact - as of July of 2013, the average age of the 247 vehicles on the road is 11.4 years old. There has been a slow increase over the past several year. Partially due to the economy but also because more houses are adding more vehicles to the family, vehicles are lasting longer and many people are financing cars for as many as 72 months. And let's not forget the collectors of the good old, sturdy and just plain neat cars. More cars and older cars results in the pollution.
Another fact - utilizing the sun, when and where it is possible, would greatly aid in the pollution issue and the need for rusting, leaking fuel storage tanks.
Imagine for just a moment - how fun would it be to pull up to a gas station to find people washing their windows and wiping off their solar panels, instead of standing there pumping a dozen gallons of fuel into their car?

It's A Bird - It's A Plane - It Is Not The Man Of Steel !
I guess it actually is a plane, of sorts.
NASA's Helios was a prototype high-altitude,
long-duration unmanned solar-powered aerial vehicle. In 2001, Helios reached an
altitude of 96,863 feet, breaking an official world record altitude for a
non-rocket-powered aircraft. In 2003, Helios broke apart in flight during heavy
turbulence.
I was lucky enough to be in the Phoenix area when the Solar Impulse landed. Not lucky enough to be at the airport, but the news was all over it and I got to see great coverage via the television. (be sure to check out the video at the end of this post)
Solar Impulse, lit with more than a dozen solar-powered lights, touches down at Phoenix Sky Harbor Airport on May 3. It's the first aircraft to fly for 24 continuous hours only on sun power.
Here's a bit on info on the Solar Impulse -
Solar-Powered Airplane Completes First Leg Of U.S.
Flight
May 05, 2013 5:04 PM
The aircraft is capable of flying at night as well as in daytime; the plane had about 75 percent of its battery power remaining when it landed in Arizona.
The Solar Impulse's "wingspan is longer than a 747 Boeing, but the entire plane weighs less than a car," as NPR's Steve Henn .
Comparisons such as that one may brought a moment of humor during Solar Impulse's trip, when the plane's pilot heard the pilot of another aircraft on his radio, asking an air traffic controller why the Impulse required a wide berth.
"Just think of a flying electric car," the controller replied.
The first leg of the trip was piloted by Bertrand Piccard; his co-founder in the venture, André Borschberg, will also pilot the plane during its American trip.
The plane has completed a transcontinental flight before — flying from Switzerland to Morocco last year, as Eyder .
With a maximum altitude of nearly 28,000 feet and an average speed of about 40 miles per hour, the Solar Impulse will — in Dallas, Saint Louis, and Washington, D.C. — as it crosses the United States. It will then head to New York City.
Along the way, members of the public can visit the plane at airports. Its pilots and crew will also visit local groups to speak about solar-powered flight (details ).
Organizers say that after crossing the United States, their next goal is to fly the Solar Impulse around the world. I'm not too proud to admit that I sometimes make opinions about a subject, when I am not totally informed or educated about it. This holds true for this solar plane concept.
I looked at this plane, and tho I was totally amazed at it appearance, I had a big question. "How practical will this plane ever be?" After all, what are you going to use it for? A drone? Maybe - but we have drone that are more efficient than this one is.
So I checked around a bit and found this info that had me thinking that I should do my research on a subject before I form an opinion. Check this out -
Environmental Benefits of Solar Aircraft
Many researchers say it's useful to park a solar aircraft in the sky. It can hover over a spot, carrying cameras or other sensors. In the stratosphere, it can sample gases near the ozone layer. It can also watch forest fires or track hurricanes on the ground.For the military, solar airplanes can help with reconnaissance. Like spy planes, they fly high, which makes them stealthy. But while spy planes must fly over and return, solar airplanes are unblinking eyes. They can take uninterrupted photos or videos for years. "When an event happens, they can study everything that led up to it," says Del Frate. For law enforcement, they're good for border and port patrol.
It's true satellites can perform some of these tasks. But solar airplanes see more detail on the ground with less expensive cameras because they're closer to the action. They're also less expensive to build and launch. While satellites are hard to move once they're in orbit, solar airplanes are easily moved. It's also easier to bring solar planes down for maintenance.
Solar aircraft, being electric, emit no exhaust. Commercial airplanes do. In 1992, airplanes emitted 0.5 billion tons of CO2, or 2 percent of human CO2 emissions. Their exhaust contains many substances linked to health and environmental effects, although the U.S. Environmental Protection Agency (EPA) regulates their levels, and health impacts near airports are being studied. Regardless, solar planes can't become clean passenger planes because they'll probably never have enough power to carry many passengers, says Del Frate.
Stratospheric jets, like the F-22A Raptor and U-2 spy planes, also emit exhaust. While they emit it into the stratosphere, where gases persist longer than in our troposphere below, their contribution to air pollution, ozone depletion and global warming hasn't been measured thoroughly. Solar airplanes that can accelerate and maneuver like these planes are many years off. So at this time, it's not practical to talk about solar planes being environmentally friendly alternatives to other planes. Still, they are clean vehicles for their current applications.
A surprising benefit of solar airplanes, says Del Frate, is that if solar panel manufacturers supplied a dozen solar planes a year with big, high-efficiency panels, the cost of high-efficiency panels for your home would go down.
There you have it. I won't be crossing my fingers to ever get a ride on solar plane but this info proves my original thoughts about the worth of a solar plane to be all wrong.
I can't wait to see where this goes in my life time.
