Which is a stupid cash grab really, as my 2002 tests just as good now as it ever did.
Not really, vehicles deteriorate and may begin to fail emissions standards. You are lucky to have a dependable vehicle that gets the same results after all these years. They are usually testing to see if your vehicle is functioning properly. In Illinois they just do an OBD scan to make sure no fault codes are present for the O2 sensor and catalytic convertor. However, even a perfectly maintained vehicle should show some deterioration in emissions performance.
We're talking about a bunch of sloppy old pickup trucks with little or no emissions controls, usually literally nothing but one O2 sensor, an EGR, a PCV, and a catalyst.
I develop vehicle emissions system for a living. An O2 sensor and a catalyst will get rid of the vast majority of emissions from a spark ignited vehicle. Little or no emissions controls would mean 1970s era cars. Think carburetor and no catalytic convertor.
No, SolarCity doesn't lease the panels back to you - they sell the power from the panels to you. And they control the rate you pay and have the ability to raise it annually (up to 2.9% per annum).
Solar city has a variety of financial plans available. I believe you are referring to the "SolarPPA" option, but leasing panels is also an option.
ESPN charges cable providers around $12/month/subscriber.
The number I've been hearing is $30/month/subscriber. However, it's tricky to nail that figure down, because Disney sells ESPN as a package with all of its other channels. That's the problem. Once it becomes unbundled, you find out how much it really costs.
The reason why diesel engines have problems with NOx emissions is because the high temperatures and pressures in diesel fuel cause the nitrogen in the air to react with oxygen.
The high temperatures and pressures in the combustion chamber cause the nitrogen and oxygen in the air to react with each other to form NOx.

Thank God there's Cyanogenmod, where my N7 is a big sluggish but still perfectly functional.
You don't necessarily need Cyanogenmod, you could just roll back to the factory image for KitKat.
Scientists will study your brain to learn more about your distant cousin, Man.
