    I have a 30mbps connection, and I live in the United States. I am 100% positive that it is not a common occurrence to receive network services at data rates above about 12mbps even with a 30mbps connection on the public internet.

An apt comparison of cable modem bandwidth would be dsl bandwidth or some other residential broadband service or provider, which I2 is not.

    Comparing to other countries is at least relevant, but the US is rapidly approaching and will be surpassing them in the not too distant future if residential bandwidth keeps growing as quickly as it has been.

    That's like saying that most offices have insufficient bandwidth because there are offices in data centers with 10 gigabit connections to the internet.

    And quantify most, Internet 2, which I assume you are talking about since you referenced Gigapops, is led by 212 universities, while there are 2,618 accredited 4 year colleges and universities in the US, hardly most. And besides that, having a gigabit Ethernet connection in a dorm room, which most definitely don't, is not the same as having a gigabit of bandwidth. The connection is shared between all the dorms, and the university as a whole. On the public internet, anything over about 12mbps is only useful with a subset of hosts. I have a 30mbps connection here, and the only public network service that can saturate the link (at about 3,800 KB/s) is my usenet provider.

    The point is, a dorm at a university isn't even an apt comparison to a apartment building, unless that building happens to sit on a data center campus.

    The point is, that even to get the Tesla to charge in as little as 4 hours, you are still going to need a 55 amp circuit in your garage to plug into. How many people in a neighborhood can draw that much additional current before the power distribution infrastructure needs massive, expensive overhauls. And while I would agree that electric should require less routine maintenance, it is estimated that the battery packs will have to be replaced in 5 years. The cost now is $20,000, and the estimate that then it will cost $12,000 which is still quite significant, considering that with gas at $4 per gallon, and driving 22,000 miles a year at 35mpg, the gas costs about the same as the battery array, without the power.

    I'm glad somebody else can take a quick look at back of the envelope calculations and realize how thoroughly incapable the grid is of supporting that much additional load at this point. And solar power makes electric vehicles even more outrageous. If we have determined that it takes 318kwh/vehicle to "fast" charge in 10 minutes, I'm willing to assume that on average, gas stations in the United States have just 2 vehicles each refueling.

    Given that the solar constant is about 1.4kwh/m squared, and assuming a generous efficiency rating on the solar technology of 30% with know overhead for equipment and regulation facilities, that means each gas station will require 1,514.286 square meters for solar collectors. There exist about 187,000 gas stations currently in the United States, brining that number to 283,171,482 meters squared. That works out to be around 110 square miles in total, which is probably a ridiculously low estimate.

    Where are you going to get the power to charge the batteries in 10 minutes? We'll use the Tesla Roadster as an example. The batteries hold 53kwh, or 190,800,000 joules. To provide that much energy in 10 minutes, it would take 318kw of power. So at 240V, it would require 1,325 amps, which isn't going to happen.

    Even at 200A, 240V, 48kW, it would take just over an hour, and that's the entire capacity of most houses in the US. While that's a lot closer to the realm of possibility, it's still impractical without a major overhaul to the electric grid. Additionally, the Tesla's range is only 221 miles per charge, so the numbers could be 1.5-2 times that.

    Even if the battery technology was here today, the power distribution infrastructure isn't, and isn't on its way either. 10 minute charges aren't going to happen unless gas stations start being constructed with small nuclear reactors that could, at the 200kw rating, provide enough juice to get one Tesla charged in about 16 minutes.

    Range and charge time are both insufficient, and are likely to remain so for the foreseeable future.

    1. Nuclear power is not carbon neutral. Uranium is mined, and nobody is running mining equipment on biodiesel, nor are they transporting it to power plants using biodiesel, ethanol, or even renewable generated electricity on electric locomotives. To be sure, the amount of carbon is extremely low per kWh of electricity generated, but very small > 0, even for very small cases of very small.

    In that case, solar power is considerably less carbon neutral than nuclear power, giving the manufacturing processes involved.

    2. As you know, nuclear proponents continually ignore the major immediate problem with nuclear power -- waste storage. Nobody wants more glass-encased nuclear waste in their neighborhood, and presently nobody wants some other neighborhood's nuclear waste being transported through their neighborhood. The nuclear industry has got to find technical and political solutions to these problems before society will embrace nuclear as a green solution. I'm not arguing that burning coal or oil is safer or cleaner than nuclear, just that any change to a status quo requires more than a slight or obscured imbalance, which is how the public currently perceives the status quo.

    Most nuclear proponents would suggest that waste be reprocessed greatly reducing its half life, and then stored in any one of the nuclear waste storage facilities that exist presently.

    3. What is Hubbart's Peak for uranium? I have no idea, but it surely must have one.

    Some experts suggest about 5 billion years, longer than the sun will support life on earth, so in that sense nuclear could be considered more renewable than solar.

    4. Which nations have substantial amounts of useful uranium? What would the balance of power be if those nations became the new Saudi Arabia of energy?

    Canada and Australia both have large reserves, and would probably be much easier to deal with politically. Uranium could be extracted from granite, coal, and seawater, and other substances like thorium, which is much more abundant in the crust, could be used in breeders.

    5. Solar off-peak is simply not a problem, not for a long time. Peak demand is highly correlated with sunshine in most of the world -- solar could serve quite effectively as the peaking plant, relying on other types of generation for base load. Electric storage is just not a major issue for solar -- it might become one for wind but it wouldn't be that hard to operate other green energy plants in a negative correlation to wind, ie burn woodchips when the wind isn't blowing, but not when the wind is blowing.

    But you still need lots of other forms of power because if the sun isn't shining on a solar plant, it isn't producing energy. More importantly, as you say, with electric cars peak energy usage may change.

    6. That said, plug in cars might change that formulation substantially, since most people would plug in their cars at night thereby adding demand off-peak [and off-sun]. If/when that happens, much of (5) becomes moot and there'd be some shifting of nighttime use [industrial, it's cheaper] to daytime and there'd be encouragement for folks to charge during the day [plug in jacks at car parks] to help keep demand during the day higher, when production due to solar is higher.

    Electric cars still have too many issues to be practical for everyone. Range and charge time are both insufficient, and are likely to remain so for the foreseeable future. Arrays of nuclear power plants could be constructed for the express purpose of electrolyzing water and creating hydrogen, which could then be shipped around and sold at stations as fuel currently is. With an energy density of 143MJ/kg, hydrogen compares very favorably to gasoline, which only stores 46.9MJ/kg.

    You arrest someone if they commit a crime, and don't arrest them if they don't commit a crime. There ought not to be any discretion of the sort he wanted to exercise. I wouldn't say that. Some discretion is definitely advisable. For example, last night I was outside of a bar a little after last call, and a guy picked up a bag of trash and threw it at another guy getting it everywhere. A cop saw this happen. He could have charged the guy with littering, public intoxication, and maybe even assault. Instead, the cop walked over and made the guy pick up all the trash with his bare hands, throw it away, and apologize. In my eyes, this accomplished several things. One, it severely embarrassed the guy, who will in all likelihood avoid doing something like that again. Two, it rectified the situation, there was no longer any real harm done, other than to the guys ego. Three, the guy now doesn't have to get a lawyer and spend about $1,000 on legal fees for a stupid mistake.

    The officer was able to handle the situation right then and there, instead of wasting a bunch of resources prosecuting a guy for having a bit too much to drink and doing something stupid. The guy definitely broke the law, but I think that the officers response was fair, while not being overbearing. I would hope in the future that more police officers would use some discretion and judgment and handle things appropriately. His solution to the problem was much more sane than tazing the guy and dragging him off to jail.
