  1. Am I a sociopath? Not really... on Explosives Camp · · Score: 1

    To actually be a sociopath, you'd need to not even understand why you'd care about that other guy, nor need to rationalize it to yourself in any form or shape

    Please note that my statement didn't say that I'm a sociopath. I was trying to say that I'm a bit closer to them than the average person. I know I'm not a true sociopath. You see, I understand why.

    Yes, there are circumstances where I'd do my best to kill another human. In those circumstances, I'll pull the trigger. The only hesitation would be verifying my aim.

    I think that it's a matter of I think that human society, as built, depends on trust. I like human society because it's nice. I don't have to break my back to get food on the table, there are cures to various diseases, etc... In return there's an element of trust, a social contract. I get really irritated at those unwilling to live by that contract as it disproportinately drags the rest of us(including me) down.

    The problem with that system is that, like geothermal, it depends upon a relativly rare geographical condition: For this sytem, a river mouth with a large amount of tide flow. While there are many such, most are heavily used by ship traffic, which complicates matters.

    As noted in the article, the facility provides .012% of France's electricity. It's only 240 megawatts. I'm sorry, but I'd consider anything under 1% as a 'niche' generation system.

    Tidal power systems that can be essentially tossed anywhere there's a tide, even open ocean, are entirely different affairs, somewhat unfortuantly.

    There's plenty of swings in markets - For home prices credit availability does have a large effect. Still, market forces to bear - home prices go skyhigh, construction companies and speculators get houses built to take advantage of it, overbuild, causing home prices to fall. Though rarely to the point that they don't make a profit on their buildings, just not quite what they hoped for. Since not so much profit is available, they slow/stop building houses.

  9. Re:battery replacements? on Improved High-Performance Energy Storage · · Score: 1

    The thing is that current hybrid batteries are as large as they are more for current capacity than energy storage. But then, as all their power comes from the ICE, they don't need any more capacity than what's needed for 'acceptible' starts and storage of stopping energy.

    When you go to pluggable hybrids or outright electrics, your battery bank becomes defined by energy needs - not current capacity. A battery pack with enough energy to get you even 50 miles is going to have plenty of current capacity for the current requirements for charge/discharge for your stopping/starting. If you start looking at a LiIon based storage system for a 300mile range car, you're talking about even a screeching stop not being able to strain the charging capacity of the batteries.

    At which point you wouldn't want the capaciters anyways, as their energy storage ability is poor in comparison to batteries by weight and volume. You might have some as part of a power regulation system, of course, but they wouldn't be considered part of a vehicle's 'fuel tank'.

    It's called collateral. You don't pay me back, I take your house/car/wife/whatever you put down as collateral on the loan.

    Collateral often doesn't cut it. That's the major reason why people with poor credit scores end up paying more interest than people with good scores, even with secured loans such as for cars and houses.

    As for interest free loans - how to you make sure people only get them as necessary? We have enough people going hog-wild with 20+% interest loans.

    Fact is, as long as we have inflation it would be in my best interest in such an enviroment to borrow as much money as possible under your scheme(government provided 0% interest loans), and pay it back as slowly as possible. Money represents goods and resources, the only way to cover said regime would be massive amounts of inflation - which would only drive more loans.

    Yes, crazy financing has certainly had a hand in it. Still, look at the response - home building went on a huge boom as well. Now the crazy financing isn't quite as available, many new homes have been built, and prices are coming down a bit.

    Still, I tend to value a home like a car - it's only worth what it would cost to build a replacement, with modifiers for the fact that a new replacement home will, on average, be nicer and safer(built to newer codes). In order to maintain value it needs to be kept up. Antique homes - like antique cars, will have additional value based on their historical value. It all ends up being very complicated.

    What significantly increases in value is the land the home is on - and don't forget things like utility hookups, impact fees, etc... The population of the USA is increasing and urbanizing - a home on cheap land that was originally out on the edge of town can now be effectivly in the center of a major city. It seems that everybody* wants to live in California or Florida, in/near a major city. No wonder prices spike there! Demand far outstrips supply, especially when cities dig in their heels and restrict homebuilding. This creates bidding wars, which guarentees pain on the part of buyers - as only the richest/most willing to accept pain win.

    Wrong analogy, I'd think. It'd be like Mr. A taking a portion of the money in the box and using it to supply the bar. The bar is supposed to pay Mr. A back(it's not a free bar) at the end of the night, more money than what went in with the chips. Mr. A is required to keep 20% of the money in the box in case somebody wants or needs to cash in early.

    Keep in mind that when you go to banks, you're talking about amounts of money and depositors that make this more a function of mathematics than luck, much like how a casino can predict it's nightly profits to within a few dollars despite having a profit scheme dependent upon small skews in odds for games of chance.

    While it might seem precarous, it's actually far better than a no-credit world. Imagine having to pay rent on a house until you could afford to buy it outright - most would never be able to own their own home.

    As for wage stagnation, I think that it's a side effect of globalization. We were on the high end of wages for over a century. With China and India industrializing, their low wages are pushing down our high wages(outsourcing). Now, we're still doing pretty good(4.5% inflation), but I don't think that we're going to see huge improvements in our effective wages until their wages catch up somewhere near were ours are. This is happening, but it's going to take time. I only hope that technology gains manage to keep up with wage stagnation to the point that we don't backslide(on average) until then.

    If you think that people just borrow money to put it into a bank, you're mistaken. I borrow money, it's for a car, house, whatever. Now yes, fractions of that are likely to end up in banks, but not to the extent you're talking about. In the case of a new home - it goes towards paying for all the building materials and salaries for the construction workers who put it together. Physical goods.

    Even if stuff ends up in the bank - remember, they have assets in the form of loans - it's not as secure as cash - but it's pretty good. Otherwise interest rates wouldn't be so low.

    But that's the FUN way to do it!!! ;)

    Personally, I think that the supercaps would be better suited for hybrids - Generally speaking they don't need much in the way of battery power, a lot of effort has gone into increasing their current capacity - both for charge and discharge.

    Fast charge would be a bonus - you want to be able to store as much braking power as possible, and discharge for the accelleration afterwards.

    Generally speaking, the wait time from starting the car to getting it in gear would be enough to slap at least a fair amount of charge into the caps for the first accelleration of the day.

    Add a fifth employee to keep track how many or how fast stores are selling out and don't send a box to a store that still has them in stock while sending multiple boxes out to the high-traffic stores.
