    You don't see them because they are expensive and cumbersome. The heating portion of the unit takes up quite a large volume of the container. What looks like a large cup of tasty hot food stuff turns out to be only a few swallows worth.
    As with any mechanical device placed in consumers' hands, there is a risk of malfunction; either not heating, getting too hot, leaking, not opening/dispensing, etc. It doesn't take too many of those incidents to get a significant number of disgruntled customers. Disgruntled customers tend to share their experience with others who then don't buy.

    A similar fate became of the self-cooling soda cans. They couldn't change the size of the container since all the vending machines were built for the standard can size. That meant there was less soda in the can since it was displaced by the cooling apparatus. Same price, less soda = unhappy customer. Turns out it's cheaper to run the refrigeration system to keep the cans cool than invent/impliment per-can cooling.

    The only place these self-heating, self-cooling gizmos are really in demand is in military environments. aNd then the temperature unit and food product are two separate parts to minimize waste due to failure (among other reasons).

    Several things to note about the FDCPA and this "drop dead" letter:

    1. It does not pertain to the creditor (the people who claim you owe them money), only to 3rd party debt collectors. If you owe money to Wired magazine and they are attempting to collect that debt directly, then they are not subject to FDCPA.

    2. Sending this letter to a 3rd party collection agency does not in any way make the collection of that debt stop. It simply moves things to the next level: civil charges (you get sued). When you send such a "drop dead" letter to a collection agency they attorney assign your account. The first thing the attorney's office will do is add some exorbitant charges for copying, reviewing and processing the paperwork and filing the court papers. Expect these charges to run from $500 to $7000 depending on the debt, state and attorney.

    3. Even under FDCPA a debt collector may contact you up to three more times to tell you each of these things. Leaving a message on your answering machine is not considered "contact" since they don't know if they are speaking to the debtor or the debtor is getting the message.

    If you owe a debt, the best way to deal with it is to deal honestly with the original firm you owe, and work out a reasonable payment plan. In most cases ignoring debt collection requests will simply yield you larger debts and more stress.

    While the white color of the siding will reflect more sunlight than a darker color, we're only talking about white light when we talk about color . Infrared is what causes most heat absorption, and infrared absorption can be completely irrelevant to color. The fact that the siding is metal means the heat that is absorbed is more easily conducted and/or radiated through the siding to the wall structure.

    If the interior walls are plaster or block then they can hold quite a bit of heat that will radiate outward over the course of the evening. Lighter wall materials like gypsum board will not hold has much heat and the house will cool faster once the sun sets.

    Hanging a shade off the western eaves will probably do wonders for keeping the house cool. Without direct sun hitting the house the interior would not get much above ambient outside temperatures, other factors excluded.

  7. Re:The ol' hose on the roof trick on Homebrew Air Conditioning for Under $25 · · Score: 2, Informative

    Your roof is only one part of the issue, probably a minor one if your have an attic.

    During the daytime the sun warms the roof and walls of a house. The surfaces most perpendicular to the Suns rays will get hotter, faster.

    In the morning the sun is low in the sky and the light rays are mostly perpendicular to the house walls. Since the air is still relatively cool from the night period, the heat imparted to the walls is mostly released back to the atmosphere.

    For the mid-day the walls are washed in light mostly parallel to the walls, but the roof is heated quite a bit. With an attic and proper insulation and ventilation, most of this heat will be released back to the atmosphere.

    In the afternoon/evening the sun is again low in the sky an the rays are again perpendicular to the house wall, causing them to heat up. Now, though, the atmosphere around the walls is also warm so less of this heat is released back to the atmosphere outside the house and instead finds it in to the home . Heat is conducted to the interior walls and then to the air in the house. Additionally heat is radiated from the interior wall surfaces to the occupants causing people to feel warmer than the thermostat reading would imply.

    The radiation portion of that scenario is why opening the windows does not alleviate your warm feeling and cooling the roof does not help much.

    If you were to run water down the west walls instead of the roof during the afternoon you could remove the accumulating heat. Better yet shade those walls, you would go a long way to keeping cooler. Another option is to more heavily insulate the western walls, building up their thickness if necessary.
    Shade is the most efficient way of keeping cool, you remove the heat before it gets to the home and either release the heat to the atmosphere, or let plants convert it to food.

    It's VERY telling to me that during the keynote we saw a demo of Mathmatica running on Intel based Macs but we DIDN'T see a head-to-head comparison of that same code base between the Intel and PPC based systems.

    If the chip is not going to be custom, then why spend the $$ for Macintosh over Windows? Apple will have zero speed advantage, zero cost advantage, and if Microsoft gets things even close to right this time, zero virus/security advantage. I'm all for style, but not when it lacks substance.

    People say that moving to x86 gives Apple the ability to leverage Intel against AMD. Big deal, that didn't help at all when Apple had Motorola and IBM to battle leverage against each other. We just wound up with both of them being laggards.

    I've not read the entire article you reference, but perhaps you should. To quote the relevant parts:
    The simplest HEV can be thought of as a battery-powered electric vehicle that also has a small engine/alternator that operates on fuels. An electric motor provides torque to the drive wheels for acceleration as well as for braking. The electric motor controller responds to signals from both the brake pedal and the accelerator, controlling energy flow to and from the vehicle battery pack.


    In other words, if you want to build a brain-dead simple vehicle,then yes you use reverse motor power to slow the vehicle.

    From elsewhere in the article:
    Brakes that last the life of the vehicle are possible because regenerative braking absorbs part of the total brake load and lowers the peak brake loads to much less stressful levels.

    This is where the technology is today; regenerative breaking. Why expend energy to slow down when you can make energy by slowing down?
  13. Re:MPG on Hybrid Drivers Provide Real-World Mileage Data · · Score: 1

    Stopping quickly does not cause any more friction than stopping slowly. All of the car's deceleration is caused by friction; it's just a matter of where that friction happens and to what degree. Stopping quickly causes the friction to happen in a shorter period of time and mostly in the active braking components (rotors,pads,etc.).

    The difference is that with shorter time frames in active braking the heat generated is not able to dissipate to the atmosphere as fast as it is generated, causing higher temperatures of the brake components. High temperatures then lead to premature wear of the heated parts as the hot parts are less tolerant of the added stresses of hard braking. Hard braking also means that you were maintaining engine power longer than necessary, and thus wasting fuel.

    Hybrid cars don't use energy from the "electric engine" to slow the car. The inertia of the car is used to drive the electric motor, turning the motor in to a generator. The resistance caused by the electrical generation is itself a braking force. The motor is not producing power for braking, it's producing power from braking and using that power to charge the batteries.

    All that said, you conclusion is correct: hard acceleration and braking are energy/fuel wasters. Constant speed cruising is the most fuel efficient driving method. Learning to drive so that you take your foot off the accelerator and coast for about 1/2 your deceleration then apply braking is a terrific way to decrease fuel consumption. It's one of the ways I average 43MPG in my VW Golf TDI.
