    American spies spy on foreigners. Including telephone taps and internet. Are you saying you didn't know that before we got to hear the codename PRISM? Heck I'm in the UK, and there's a USA spy base here. It's no secret. Back a couple of decades their program was called Echelon. And it was the instigating reason for my then company starting to use PGP.

The trick is to realize that 'the government' isn't a person, or if it is, it's a multiple personality schizophrenic. The left hand literally doesn't know what the right is doing. Thus, you have to assess each program, each policy, somewhat on it's own.

    Programs are one thing, but when it comes to law - watch out. NEVER trust them if they say 'Oh, sure, it could theoretically be used to prosecute case X, but we'd never use it for that!'. Normally it takes about a year from hitting the books before they're using it to prosecute case X. See anti-terrorist laws for a recent example of that, what with 'domestic terrorist' labels being applied willy-nilly.

    First, When posting off-topic, it's best to post anonymous to preserve your reputation. Thus why the AC posted that way.

    Back on your topic. It's true that 'distribution' doesn't start at the plant and end at the wheels, though I'd say that for an EV it does tend to 'end at the wheels'. It's just that it gets very, very hairy once you start looking past the plant. Sure, you can analyze a specific source/plant/generation facility, but if you analyze a different one the numbers can be completely different. Even averages are hard to come by.

    Are you looking at a solar plant or wind turbine? How much energy went into creating the system, how much do you expect to get out of it, what's that individual KwH's share?
    What about Natural Gas? How much energy went into drilling for the NG, collecting and purifying it, and shipping it to the plant? 60% efficiency for the plant itself.
    Coal? Most coal plants are located close to their mines for logistical reasons - it's more efficient to ship the electricity than to ship the coal. Still, mining and shipping of the coal needs to be accounted for. You're looking at 40-50% efficient for coal plants.
    Nuclear? Mining and enrichment(if necessary) of the Uranium needs to be added in. 30-40% efficient.

    Still, you contend that hydrocarbons are 'cheap to ship'. Well, coal isn't that cheap to ship due to the shear amount of it necessary. Natural gas either needs to be piped(and NG pipelines are expensive to run long distances), or it needs to be compressed to a liquid. This costs $1.50-$2 per mcf. This is significant, considering the wellhead price of $3 per mcf. Shipping runs $.30 per mcf.

    Liquid fuels such as diesel and gasoline, of course, need to be extracted from a well, shipped as crude to a refinery, refined(~70% efficient), then shipped to the final destination. I think that you'd find that it's quite hilariously expensive from that perspective, in line with power plant costs.

    The vast majority of real studies have figured that even if you use a relatively dirty coal plant for power that EVs still come out ahead energy wise due to the shear efficiency.

    The grid is better than 90% efficient, on average, the charger is better than 90%, as is the battery and motor. You go beyond that if you still want to compare it to IC vehicles you have to look at energy losses in pumping out of the well, transporting to the refinery, then to the distribution point, etc...

    It would take a lot of efficiency within the hydrocarbon supply chain, and a lot of inefficiency in the electric one, to make up for the difference between a ~73% efficient plant-wheel EV w/regenerative brakes vs the 20% efficient engine and 80% efficient transmission, with no regeneration of a gasoline engine.

    Tesla can be recharged to 50% in 20 minutes if you are using their supercharger.

    Looking up the site's claims, it's '50% in 20 minutes', I'm taking that as +50%, not TO 50%. IE if you start at 20%, you'll be 70% when you're done. If you're really close to 0% you might get a touch more, if you're close to 50% you might get a bit less. Given that Tesla sets their battery's '100%' to more like 80% of true capacity for longevity purposes, you shouldn't run into the problem where the last 5% takes as long as the first 50%.

    Stopping for 20-30 minutes every 100-150 miles is not practical.

    Well, it's a good thing that the range is 265 for a model S. You might be able to Ironman driving, but I like to sit down and have a good meal every so often. That's without getting into a number of different possibilities:
    1. The proposed on-road charging, which should enable you to finish a drive with most of the charge you left with, even if it doesn't enable charging the battery at all.
    2. Even more increased battery capacity - we saw an article about lithium-sulfur batteries not long ago. Even if it only 'doubles' the range - that's 530 miles of range, or 8 hours of driving at 65 mph. You want lunch, right? If you utilize a high speed charger for an hour during that, you should be able to hit 14-16 hours of driving easy.
    3. Generator trailer: I LOVE this concept. When people are on long trips is generally when they want to haul the most stuff. Make a small trailer incorporating a 5 gallon tank and a 15-20 kw generator in addition to some extra storage. The Tesla model S should use ~21kw@65, but if you're supplying 75% of the energy, you should be able to travel 1k miles before exhausting the battery, and just let it keep running for a bit if you're camping to charge the batteries back up. A 20kw version shouldn't cost more than $13k. See #4 for the idea of simply renting the trailer when you need it. If it runs the full size price, you're still looking at 65 weeks of renting it to make it cheaper to buy.
    4. Week long rental costing 10% of the cost of a car? What kind of cheap-ass cars are you looking at? I see $45-65/day, $315-455, $3-4.5k doesn't generally get you a car I'd trust on a highway. Heck, Enterprise, checking a non-airport location, gives me a rental price for a full size at $200 for a week. You can get a 'intermediate SUV' for $320.
