Just like at Eater Island, the natives destroyed their ecosystem and perished from the face of the earth. Maybe it would be a good idea to have a small footprint on our Mother?

Romancing the Road
540,000 miles from one car, one owner. And they are both pretty cool! The owner is 89 and the car is a 1964 Mercury Comet. She aways gets lifetime warranty replacement parts (16 free batteries so far) and carries a pistol (licensed) for protection on the long trips. Really worth watching.
These are the people and cars that made America great. I guaranty this car has done less damage to the environment for all those miles of travel than the average Prius owner does today. Why? Because once it was built, it was never discarded. If you really want to help the earth, rescue an old classic from the junkyard and pay a local hard working mechanic to restore it.

Best advice I've heard in a long time...
If you hear that the world is ending and the Messiah has arrived, first plant a tree, and then see if the story is true.

Sustainability = frugality over the long term
here is the big secret:
Actual sustainability = frugality over the long term.
If it costs more over its lifetime, it is NOT sustainable. So, when gas is at $2.50 a gallon, the Prius is NOT always sustainable.
Proof: The cost of any item, in the end, is the energy required to make it. All the metal, plastic, glass, etc.. needed to make a Prius is just setting in the ground, free for the taking. The real cost of making it into a Prius is the cost of the energy required to dig it up, ship it to the foundry, refine it, ship it to the parts factory, form it, ship it to the car factory, assemble it, ship it to the lot, and sell it to you. All of the equipment and people involved in those processes are, again, the cost of the energy required to make and operate.
Just about ALL of that energy is fossil fuels. So how does it make sense to spend $22,000 (http://www.toyota.com/prius-hybrid/trims-prices.html) worth of fossil fuel to get 51/45mpg, when you could spend $12,000 (http://www.toyota.com/yaris/trims-prices.html) worth of fossil fuel to get 29/35mpg? You are saving about 20mpg, or 12.5 cents per mile, for an expenditure of $10,000. You would have to drive 80,000 miles to make that worth doing. Given a 5 year average vehicle life, you would have to drive 16,000 miles per year or an average of 45 miles per day. So if your commute is less than ½ hour each way, a Prius actually HURTs our Mother more than it helps.
Of course, the numbers REALLY make a jump when you consider a USED car vs a NEW Prius. A 25mpg 2001 Camry for $10,000 with an average useful life of 20 years turns out to be a much more sustainable choice than a new Prius for that same 30 min commute.

The REAL green people drive old cars and support their local mechanic until the repair bill exceeds the savings.

Chickens
A friend asked how hard it is to raise chickens. I answered as follows, based on my research into the subject (not based on personal experience since I'm not allowed to keep chickens where we live inside the city limits *wink*)
Chickens must be the easiest and most productive animal to raise. They need a run, a coop, food, and water. Other than the materials and labor to set up the run, coop, etc... The only maintenance required (assuming the run is big enough and you setup the coop correctly) is refilling the feeder, and cleaning out the water dish on a regular basis to keep disease at bay. A poorly designed coop will require regular cleaning, and a run that is too small or poorly placed will require hay or other composting material and semi-regular mucking out.
A rooster is NOT required for eggs, although some people claim that only fertilized eggs are worth eating.
Tips:
Set the run up on a slight slope, with the high end having easy access to throw in compostable materials (food scraps, lawn clippings, garden waste, etc...) and the low end having an easily removable gate to shovel out the lovely rich compost / fertilizer they produce. The ideal setup would have a drop of a few feet from the low end into a compost bin where the mixture of chicken poop and compostable material would drop and cook into a rich but usable material for your garden. Chicken poop is to rich to use directly, so it must be mixed with other materials (they do that naturally in the run) and then let set for some time to cook.
Setup the coup OVER the run (or lifted up on stilts) with a chicken wire screen under their roosting perch and a very slight slope (darn near flat) from the nesting boxes down to that screen and just a strip of wood to keep the eggs from rolling out onto the screen. Then the nesting material (sawdust, etc...) will randomly migrate out and down through the screen, they will poop through the screen while roosting (which they do a LOT) and that poop will be mixed with compostable materials in the run as they scratch through it. Chickens have a close relationship with their own poo. They let bugs, maggots, etc... grow in it and then scratch those out an eat them.
If you build your garden beds high enough and surround each bed with a waist high fence, you can let the "girls" out once in a while to clean the back yard of snails, bugs, spiders, etc... They don't like to eat ants, and they DO like to eat your best garden greens in the most destructive and wasteful ways possible. E.g. just the main root from each pepper plant.
Downside:
Smell: Really not as bad as people think, assuming the run is large and either setup smartly or kept clean with manual labor. But there is a bit of a whiff on hot days...
Flies: No matter how clean you keep it, chickens shit, and you will get flies.
Spiders: Spiders follow from flies. We have more black widows per square foot than any place I've ever lived.
Garden and grounds: They WILL get out, and they WILL destroy something you lovingly planted. They like to scratch or dig up flowers, veggies, etc... Any area that they frequent will be laid baron by their constant digging for bugs and the overly rich power of their poop.

20% better MPG from an electro-magnet? Must be a joke, right?
In the "are you kidding me" department, we find this report of a simple device consisting of an electrically charged tube that can be attached to the fuel line of a car’s engine near the fuel injector. Using power from the vehicle’s battery, the device creates an electric field that thins the fuel, reducing its viscosity, so that smaller droplets are injected into the engine. That leads to more efficient and cleaner combustion.
And who says so? Has to be a quack, a jerk, some backyard mechanic? Errr. no, actually, it's Temple University.
http://www.temple.edu/newsroom/2008_2009/09/stories/taofueldevice.htm
"Six months of road testing in a diesel-powered Mercedes-Benz automobile showed that the device increased highway fuel from 32 miles per gallon to 38 mpg, a 20 percent boost"
"Temple has applied for a patent on this technology, which has been licensed to California-based Save The World Air Inc., an environmentally conscientious enterprise focused on the design, development, and commercialization of revolutionary technologies targeted at reducing emissions from internal combustion engines."
I believe the patent application is for number 20080190771 It seems to be for a device that uses the electric power from the battery to create a magnetic field around the fuel.
So do those con artists who sell the perminant magnet thing you put on the fuel line actually have something going on? Mythbusters, and many others, proved that they don't. So what gives?
The patent application says: "It has been surprisingly found that if the applied magnetic field is a short pulse, the induced dipolar interaction does not have enough time to affect particles at macroscopic distances apart, but forces nearby ones into small clusters. The assembled clusters are thus of limited size, for example of micrometer size. While the particle volume fraction remains the same, the average size of the "new particles" is increased. This may lead to the reduction in apparent viscosity because the value of the crowding factor k, is reduced. "
So it's a pulse, not a continuous application, that makes the difference.
Pulsing a magnetic coil with a specific, adjustable, duty cycle and pulse width is taylor made for microcontrollers like the PIC or MSP430, and pretty easy to do.

Buy a Prius, kill the earth?
The cost of anything, when you break it down and break that down and so on, turns out to be the total cost of the energy required to make it.
To make a Prius you need about $28,000 of energy. For example, the metal parts have to be machined (coal for electricity for the mill/lath/cnc and everything it takes to support the worker including fertilizer, pesticides and so on used to grow and transport his or her food) but first the metal must be transported (diesel) and before that smelted (electricity or NG) and before that the ore is hauled (diesel) and mined (diesel, etc...) and so on. The metal doesn't cost anything, it's just sitting in the ground as ore waiting for us to take it. ALL of the costs to make that metal part are the energy required to transform it from the base ore.
The point I'm trying to make is that the COST of the car is the ENERGY used to make the car.
We expect cars to last about 5 years. On the bleeding edge, one tends to bleed. Hybrid cars are not well tested, although they do seem to be holding up well in fleets and as rentals. Let's give it the benifit of the doubt: This thing is going to cost you $28000 / 5 (years) / 52 (weeks per year) / 7 (days per week) or about $15.38 per day no matter how much you drive it. That is how much oil, diesel, coal, fertilizer, pesticide, etc... you will consume with this car each day without driving it at all. If you drive it 40 miles a day (which is about the national average) then you will be spending 38 cents per mile, NOT including the gas.
At 47 to the gallon and gas at $4 (for now) that is $3.40 more or 8 and a half cents per mile. Add some regular maintenance, you are looking at about 49 or 50 cents or per mile.
That is the bottom line: A Prius costs you, and mother earth, about 50 cents per mile.
A Hummer, by the way, costs about a buck a mile.
My $10,500 used 2001 Camry, purchased in 2007, given that it has one of the highest reliability ratings in the world, will very probably last 4 years MORE or 10 years total. It has a proven track record. The mfgr warranty for most of the car is actually 8 years, for pity sake.
$10,500 / 5 (years I plan to own it) / 52 / 7 = $5.77 per day. It gets 23MPG (25 estimated, 23 actual) and I drive about 50 miles per day so add 2.18 gallons of gas at, say $4 dollars per gallon. That is $8.72 per day in gasoline for a daily total of $14.49. I have almost $5 a day more than you to put towards maintenance and repairs.
But that is with my crazy commute. In terms of cost per mile, I pay less than 12 cents a mile to own the car and less than 18 cents a mile to drive it at $4/gal. So that is 30 cents a mile!
If gas stays at $4 I save 20 cents a mile over you!
38 - 12 is 26 cents a mile allowance I have for gas more than you do just because of the base price of our cars. Gas would have to be around $6 a gallon to justify my purchasing a Prius.
At $6 a gallon, there are a LOT of sources for fossil fuels that start making economic sense and so will become available. Oil shale extraction in West Virginia, algae bio fuel, etc...
Maybe they will come out with a lower cost version of some of these hybrids in the next few years and all of this will change, but for now, driving an old beater is the most ecological thing any of us can do.
And then there is the crash test ratings...
