    Have you even seen a lithium ion battery go anywhere near 10-15 years? My current cell phone could go one week without recharging when I bought it. Less than a couple months into ownership, I can barely go 2 days. Yes, lithium ion batteries can be recharged 500 times, but saying that you will go anywhere near the full 250 miles on that 500th charge is assinine. The deep charge/discharge cycles gradually affect the chemical makeup so that the battery can no longer hold the same charge.

    More importantly, Lithium ion batteries age whether or not they are being used. According to Wikipedia they can lose 20% of their charge capacity of a year if stored at 20c, which is around 75f, not that far off from normal daytime temperatures, and who knows what operating the car will do to the temperature: it could vary wildly based on where the batteries are located, what cooling they use, etc. (Charging and discharging batteries is not 100% eficient and so gives off a fair amount of heat.) Let's give them 15% losses per year, from storage alone. That means after the first year the battery only has 85% storage capacity, after the second year the battery has about 72.5% storage capacity remaining, after the third year around 61% of storage capacity remains. So, after the first year you get an average of 212 miles per charge, after the second year you get around 180 miles per charge, and by the end of the third year you're down to somewhere around 150 miles per charge. And that's not including the wear and tear on the battery from deep charge/discharge cycles, which will occur more and more often as the battery ages and the charge becomes more and more shallow. I would honestly assume less than 100 miles a charge cycle by the end of the third year. If you haven't replaced the batteries or just garaged your 80,000 car by that point.

    Granted, for someone who has the money and wants to go really fast, a pure electric car with lithium ion batteries may very well be the way to do it. But for a reliable mode of transportation that anybody but rich playboys can afford to maintain (Remeber TCO, boys) lithium ion batteries are not the best choice energy storage method.

    "All you have to do is replace the batteries, probably once a year." From the summary, the car runs on 6,831 laptop style lithium ion batteries. A quick froogle search reveals that a replacement lithium ion laptop battery runs around $90 - $150. Let's assume $100/battery. Since you'd be buying in bulk and using batteries designed for this purpose, I'll give you a 90% reduction in cost (overly generous) which puts you at $10/battery. That means your annual battery replacement is almost $70,000 (I.E. most of the price of the car.) And we haven't even charged the batteries yet. Most people I know with anything approaching a reasonable car fill up maybe once a week for under $50.00/tank. That puts you at $2,500 annual fuel cost, add in a quite generous $1,000 for maintenance and repairs, and $1,000 a month for insurance and loan payment brings you to a little over $15,000 annual cost of driving a relatively decent newish car. So, assuming a lithium ion battery pack lasts four years, it would still be cheaper to own and operate, and insure a gasoline powered internal combustion vehicle than to simply change the batteries on this car. And I'd be willing to place a decent size wager that trying to outfit any significant portion of U.S. vehicles (Let's say... 10%) with lithium ion batteries will cause a tremendous surge in demand for lithium, driving prices sky high. In fact, I'll do the math. Lithium has a specific energy density of up to about 200 Wh/Kg. Many major electric vehicles use around 300 Wh/mile, so I'll be generous and say 1 Kg of lithium storage will get a driver 1 mile before recharging. American passenger vehicles drive around 2.5 trillion miles per year, which works out to around 6 billion miles a day driven by americans (An average day's driving being the absolute minimum charge you would want in a car) which means we would need 600 million Kg lithium to make enough batteries to replace 10% of passenger cars. That works out to a bit over half a million tons of lithium. In the year 2005, only 18,000 tons of lithium were mined WORLDWIDE. That means we would need over 25 times the current annual worldwide lithium production just to make enough lithium batteries to give ten percent of U.S. passenger vehicles (cars, light trucks, SUVs) enough charge to drive for one average day, with pretty generous rounding in favor of lithium storage at almost every step I took. That's not even touching the semis, construction equipment, mass transit, airlines and ocean liners that actually keep our society running. And then there's the issue REPLACING the batteries, although I assume there would be large scale lithium recycling implemented.

    So I don't foresee lithium being a long-term cost effective material for energy storage in our transportaion system.

    This really depends on the network, and what you are trying to accomplish with it.

    Let's consider two major online sales venues (The models will be idealized a bit, but...)
    Amazon: Adding customers to Amazon does not really increase the value much to each customer, maybe Amazon is capable of getting better rates of bulk purchases from publishers, and is financially able to stock more books, but the growth of the value of Amazon is fairly linear with respect to number of users.
    eBay: Adding users to eBay has a direct positive correlation to existing users: More users mean it is more likely that shoppers will be able to find the items that you want, and people selling will more likely to find someone willing to buy the items at the desired price. There are exceptions, of course. Amazon does list other sellers as well, and therefore bringing in more customers means more people would be willing to offer their products on Amazon, which offers better selection to customers.
    Also, eBay would not have a literal N^2 total value curve, in that more users means that both buyers and sellers are going to run into more competition (driving prices up for the buyers when other people want to buy the same goods as you, driving selling price down for sellers due to other people offering the same item or an equivalent good.) But in general the ability to find someone willing to buy or sell rare items will increase as the number of users goes up.

    But any of these models really won't accurately model the total value of a network, although it MAY be possible to model a given implementation of a network designed for a given purpose, it would likely require a complex polynomial with some coefficients even being negative. At certain size ranges it is even possible that adding more nodes to the network reduces the total value: troublesome choke points can be stressed reducing reliability, or the network could grow large enough to allow for parasitic elements to thrive (Spam, Viruses, Spyware, Trolls, Scam Artists, etc) but then increasing the network size even further could overcome these negative traits, I.E. making the network large enough for checks and balances against the parasitic elements, making it financially worthwhile to solve the bottlenecks with new technology or physical network topologies.
