  1. That is what we have courts for on Challenge To US Government Over Seized Laptops · · Score: 1

    The 1st Congress (who could be presumed to know what was intended by the 4th amendment) passed a law explicitly allowing for searches of anything and everything at the border.

    The 4th amendment does not prohibit search/seizure without a warrant; it prohibits "unreasonable" search and seizure without a warrant. "Reasonable" can be determined by statute, subject to review by the courts.

    Tesla's work involved magnetically coupling the receiver with the transmitter. Recently MIT even used it over short range to provide useful amounts of power with reasonable efficiency. (Witricity is a spinoff from this effort. Their first predicted application is indeed wireless small-device charging.)

    Pointedly, the wireless power transmission isn't using radiative broadcast for this; they are using magnetic fields.

    You can transmit useful power using 2.4GHz signals, but it is either directional or it is contained (like your kitchen microwave.)

    The GMO corn is used because it maximizes yield per acre. We eat more corn than we would otherwise because of the subsidies, but that doesn't mean that we wouldn't eat corn at all without them. It remains a good animal feed, the base for an inexpensive sweetener, a good source of oil, an excellent base for fermented beverages, etc.

    Oops... forgot to complete 3...

    Initially, I imagine that until GM releases battery wear life figures, it will be difficult to estimate costs per mile. Their batteries will be cycled more often, due to the lower capacity, but they have chosen to extend pack life by only charging the cells half full, and begin recharge at 30%. (It's unclear if that's 30% of total cap., or 30% of the cap they actually use.)

    1) Get the 300 mile range out of your head. That is the factory-fresh range. The batteries won't be factory-fresh for long. Their own estimates for the roadster pack are for nearly 1/3 capacity loss after only 50k. I can easily drive 200 miles in a single stretch. I do so every time I visit my parents; it's not an unusual road trip for anybody. (It's 250 miles, one-way.)
    2) Yes, the Volt battery will wear out, as do all Li batteries. However, since it is much smaller (and will have fewer cells) it will inherently cost less. Initially, I imagine that
    3) Tesla, absent a gigantic fusion of capital, can't afford a nationwide network of charging stations, nor is the power grid equipped to handle them.
    4) I did compare a 17" touchscreen to a simple single-speed 4 cyl. engine. I imagine the software to drive all that 17" touchscreen goodness is rather non-trivial. You can't determine complexity by counting moving parts. And why do you keep harping on the exhaust system? It has all of four parts: the Cat, two O2 sensors, and the muffler.
    5) I imagine the largest market for quickcharge stations would be long-haul routes. Given the highly-used long-haul I-95 Corridor, the power feeds required for all those stations would be mind-boggling.
    6) According to a website referenced on the Tesla Motor Club forum, there are currently 18 Charging stations in North America. This is hardly a "network." I'd be surprised if any of those could feed more than one car. Oh, and they aren't quick-charge stations, they are 3 1/2 hr stations; hardly "quick."
    7) The Volt most certainly is NOT a "Prius made by Chevy." Think of it as an electric car with a generator under the hood. All of the complexity involved in Toyota's system to have the engine and electric motor working at once disappears. Instead, it's no more complicated than your alternator driving a motor.
    8) The full-range S is priced at 65k. The Volt is expected to come in at less than 40k. That isn't 10-15k. (The Volt will lose money out of the gate, just as the Tesla did...)

    The Tesla Roadster and S are certainly useful exercises in design, and are, and probably will be, in the future, great testbeds for EV development. But right now, I just don't see them providing the flexibility needed for a primary vehicle. If they can chop the price in half (so you can buy a gas-powered backup), and show a track record of affordable battery depreciation, yes, but not until then.

    The Volt provides a great compromise: enough juice for most commutes, along with infinite range for when you need to go farther, and NO purpose-built charging stations (or easily-accessible 220V outlets) required when you are away from home.

    300 miles is not a full day of driving, period. After the battery pack has worn down some, the 200 mile range you are left with is quite limiting indeed.

    Without battery standards, and millions of Tesla vehicles on the road, who is going to build those battery-swapping stations that get around the range limits? And buy the batteries to stock them? I cannot imagine a nationwide network of battery charging stations for a single niche brand of car.

    They most certainly DO NOT charge to full on a standard 110V line in 3-5 hours. (110V * 20A * 5 hours != 85kWh. The Telsa website says the 110V charger is 5mph of roadster range.) A single quickcharge requires an 66-kilowatt feed (480V, three phase, 80A.) A network of quickcharge stations, each with multiple outlets is almost inconceivable with the current power grid.

    Next, their more "consumer-oriented" product is most certainly NOT shipping next year. (The S is not a consumer-oriented product, and it still isn't actually here.) That would be the BlueStar, and there aren't even models, much less prototypes or a schedule, available.

    The 50k solid lifespan of the battery is very relevant when you have to pay for a new one; this drives up the cost of a Tesla trip by a huge amount. It costs waaaayyy more than $4 for that 200 mile trip when you take the costs of the battery wear into account, which you can be sure a battery changing station would. For the Roadster, pre-paying seven years in advance for the battery (with a half-life of 100k) runs $12,000, giving you a CPM of $.12, making the cost per change $24, just for the battery (which isn't even available for immediate ship at that price, not counting the electricity itself, the station, its facilities, or profit. If you want to stock your station today with batteries, they'll run you triple the price, giving you a cost per 200 miles of $72. (I will admit this is Roadster battery pricing, but S battery pricing is yet to be released.)

    And let me get this straight: you are touting a 17-inch reconfigurable touchscreen as a feature (why does a car need a 17-inch touchscreen?), and then complaining that the single-speed, 3-cyl engine with no gearbox in the Volt is complicated?

    I don't WANT to spend an extra 10-15k to get off of electricity entirely. I want to spend less money and be able to use the wall power for my daily commute, and gas to go as far as I want.

    The large battery pack that is supposed to produce that range will weigh over a half ton. And 300 miles still isn't a full day of driving. On a car not shipping yet and with no firm production date. And that is the range fresh out of the factory; for the Roadster, the specs call for the range to drop by nearly a third after 50,000 miles of use.

    Swapping batteries at gas stations? Without even hints of a standard for battery packs? Not a chance. Not for a very long time. And not without major upgrades to the electrical infrastructure. (The size of the feed for even a single busy "refueling" station would be mind-boggling.)

    The virtually inevitable future of ground transportation isn't petroleum, since we will indeed eventually run out. However the obstacles are too many for a pure EV to be used as anything but a commuter car. (Namely, EV's are entirely useless for long-haul driving, with the even the longest range vehicles only providing less than 1/4 of that needed for a long haul trip. And no, you can't quick charge without MAJOR upgrades to the infrastructure.)

    Doing the lion's share of your driving on batt., charging slowly at home, and still having the gas capacity for a long-range trip is a good compromise, and one that I think will carry us through the next couple of decades of auto development.

    Incorporating a tiny, tiny, business has far fewer advantages than most entrepreneurs think, and, as you are finding out, imposes a large pile of PITA paperwork burdens. A cookie-cutter S-corp with only you and your wife as shareholders is not likely to provide much protection from legal liability, which is why most people incorporate to begin with. The courts could quite possibly see that the corporation is merely a layer of paperwork on top of your own personal assets. In any case, the legal fees fighting that issue in an attempt to protect your personal assets could easily bankrupt you, personally.

    Yes, it is possible to build an S-corp that provides a proper layer of abstraction between you/your wife, and your corporation, but the time to do all that would have been when the corporation was set up, not now. When the S-corp is set up, and maintained, in a sloppy manner, the courts find it far easier to pierce the corporate veil.

    However, for hairier apps, or more abstract things, the well-rounded background provided by a CompSci degree is valuable. A CompSci degree will include a broader range of technical courses, along with courses in business, economics, and "teach you how to think" classes like history, calculus, physics, etc.

    As a side note, Slashdot should have commented on or re-worded the question, which was most obviously written by somebody who is pissed about a lack of job opportunities for his/her degree-less self.

    Personally, I have yet to directly use my degree in Computer Engineering at all. In ten years, I haven't written a line of code, haven't assembled a single circuit, much less done any calculus or physics. But in my department, it is easy to tell who has gone to college and who hasn't, by means of how long it takes them to absorb entirely new topics, approaches to problem solving, etc.

    It most certainly is possible for a 2-yr grad (or even somebody with no formal training at all) to produce great code, and it is possible for a PhD to produce code awful beyond belief. But all else being equal, if I was hiring, I'll take the college grad any day of the week.
