  1. Flash wears out. Smaller flash wears out faster on Most SSDs Now Under a Dollar Per Gigabyte · · Score: 2

    okay, unlike processors, it's already known that flash only has so many write cycles before it's worn out. Thus far, the reports I've read say that smaller process flash, especially MLC flash, wears out quicker. HOWEVER, shrinking the process so you fit 4X the cells into a given area doesn't give you cells with 1/4 the lifespan; maybe 2/3rds, maybe 1/2. That part isn't clear. Thus, a theoretical 1TB flash chip might only have 10TB worth of 'writes' to it, that 10TB is still better than a 1GB chip that has 100GB worth of writes. Wear leveling takes care of the rest.

    More likely, if a small quake is going to put enough pressure on another area to make it fire off "the big one", then the large quake from an unrelieved fault is going to impact a lot of "another areas" and fire off a lot of "the big ones" in rapid succession.

    Which is probably why earthquakes often start off somewhat small, then get big, then you have a lot of aftershocks.

    I think the situation is such that artificially stimulating earthquakes will, on average, reduce tension between the plates and reduce individual earthquakes - and as tremors below certain energy thresholds don't really cause damage, while moving up in energy level causes rapid increases in damage. Thus, four 3's probably do less damage than a single 4.

    Still, there are individual cases to worry about - before you go artificially tripping a fault, you're probably going to want to model stuff so that you DON'T trip the 'big one' when you're not ready.

    I somehow dropped the 'eventually' I was intending to put before 'deliberately'. Basically the idea is that maybe, in the future, we'll be able to detect high-stress points and deliberately inject water there to trigger lighter earthquakes to prevent bigger ones, using techniques developed for fracking, as opposed to fracking for natural gas and hoping it prevents an earthquake. Even then we'll likely be a long ways of telling what day the earthquake would happen, such that vulnerable structures could be reinforced(perhaps temporarily*), people could put all their stuff on the floor and go camping, etc...

    After that, let me let you in on a little secret. I'd bet there are more PV panels per capita in Alaska than Nevada.

    I know of 2 installs here in Fairbanks. I'm willing to bet there's a lot more down in Nevada, even per capita, though the remoteness and low population density which makes our electricity bloody expensive makes PV attractive here, at least in the summer.

    http://en.wikipedia.org/wiki/List_of_countries_by_oil_consumption The EU has more population and lower oil consumption. Thus savings measures will have a greater effect in the USA than Europe. Thus, EVs *should* be adopted in the US before Europe.

    You live in Alaska and you don't know that there are more uses for oil than simply burning it in automobiles? I use approximately equal measures in my truck and house! If I had a family and the house was occupied more I'd be seriously looking at wood.

    In any case:
    Fewer cars? False. Though if you include 'all' 4+ wheel vehicles, we take the lead again(though it's still around 75% as many vehicles per capita).
    Fewer miles? 14k km(9k miles), vs ~15k miles, though latest DOT is closer to 13k. So about 50% more. Your earlier assumption of 8k km was therefore only slightly above HALF of what the statistics actually say about average driving over in Europe, and is still less than if you misstated and meant miles. Plus Americans are driving less as well.
    Better Economy: True, but I never disagreed with you there. On average, US vehicles use 32% more fuel. Still, Europe averaged €1.59/liter vs USA's $3.85. A US gallon is 3.79L, And 1 Euro =$1.28. Making European gas $7.71/gallon. Adjusting for the average superior mileage of European vehicles, they're still falling behind at $5.84/gallon equivalent. Raise prices that much and Americans drive less.

    Again: My statement was merely trying to state that EV adoption should be quicker over in Europe.

    1, The battery is the single thing that drives the cost of an EV higher than a traditional gasoline vehicle.
    2. An EV driven less doesn't need as large of a battery.
    3. A denser average population also means that potential charge points are also more common.
    4. The cost of fuel is far higher in Europe

    Conclusion: Small EVs should be quite popular over there(if they were 'almost' economical in the USA), but they're not, so they're not really that close yet.

    Most of the land in Alaska has no access to any utilities at all.

Still, this was part of the impetuous to move towards LiIon.

Yes, l/100k is the standard measurement over there, but YOU mentioned '60+ mpg'. Which are generally for ultra-economy diesels and using imperial gallons in the MPG calculation. It's closer to 50mpg if you correct for that. Then there's the differences in the measuring standards. Europe tends to be 'nicer' in that they tend to rate vehicles as more efficient than the states.

    The problem is that they don't rely on cars as much. Why? Because of the high prices.

    'As much', but the USA has a population of ~300M, Europe has one of 738M. Translation: Even if you have half the cars per capita, you still have more cars than the USA.

    They solved the problem before there were electric cars, so electric cars aren't a solution for a problem they have.

    Electric cars have been around since the early 1800's. There's no 'before', unless you go back before IC vehicles as well.

    An EV eliminating that would save three times as much as in Europe where the cost is twice as much.

    Exactly.

    They drive smaller cars less, and trading a family car using less than 5l/100km for a equivelent sized car thats EV will save (8000km/yr*5l/100km=400l*2$/l=) $800 per year.

    Is a 47mpg equivalent car & 8k km/year really any sort of 'family car' or 'average' over there? I recognize the US figures. Still, the lower miles driven and smaller vehicles actually allows for a lower ranged, cheaper EV to be used. While US consumers will, by and large, sneer at a 'mere' 100 mile range, over in Europe I see a lot more being accepting of a 100km range. Shrink the battery and you reduce the cost of the major component driving the price of an EV higher than gasoline vehicles(an electric motor runs about the same price as a gasoline engine of equivalent power).

    Europe has already "optimized" for lower prices with lower distances in smaller cars. The US has much further to go, and so *should* logically see greater improvement with EVs than Europe, as every EV in the US is replacing a less efficient car traveling longer distances.

    'Every EV'? You get people who drive a lot in Europe, and people who don't drive at all here in the States. Logically speaking, you get a gradual adoption as EV technology improves and the economics make more sense. Early on you have people buying an EV because they want an EV - economics don't really enter it. Later you get 'edge cases' - like a company that buys EVs for their warehouse/factory area because they can drive them inside without worrying about air quality/monoxide(same reason you see a lot of electric forklifts in warehouses). That transitions to people who have driving styles 'perfectly' suited for them, and it spreads.

    I wasn't trying to say that 'every' car in Europe would be an EV, just that, like solar panels being installed in Nevada before Alaska, it's a 'better situation' over in Europe for EVs.
