    Either propane costs 10 times what natural gas does...

    Google tells me propane costs $2.50 a gallon currently. Google also told me there are 91,600 Btus in a gallon of propane.
    1,000,000 / 91,600 * 2.50 = $27.29 per MM Btu.
    Google says natural gas is at around $5.80 per MM Btu.

  3. Re:Solar Charged Laptops? on Top Tech Breakthroughs of 2008 · · Score: 1

    Solar powered laptops, is something I had been waiting for. Maybe I am day dreaming, but the back of LCD panel could be fully covered with Solar Cells and trickle charge the battery, which might run my laptop for 5-6 hours before needing recharge. I guess solar cells have not become that efficient yet, but, is anybody trying it?

    My laptop (Dell 1420) has a 13.13"x9.61" surface area. That is 0.0814 square meters.
    Looking at a solar insolation map most of the westernized world would be lucky to average 200W per square meter on an optimally tilted panel.
    200W per square meter x 0.0814 square meters = 16.28W.
    30% cell efficiency x 16.28W = 4.88W.
    Said laptop uses a 56 Watt hour battery and lasts about two and a half hours on it with light use. That is a 22 watt consumption rate.

    So using this laptop outdoors with great solar cells and perfect aiming of the lid (which is not the ideal aiming for viewing the screen) will add about 30 minutes to the runtime. In real life conditions you would get much less.

    Second, nobody's been investing in airport infrastructure. The planes are getting bigger but the runways aren't and we're not adding new runways either. Part of it is politics but a lot of it is economic.

    The FAA is investing in airport infrastructure. Replacing ILS with LAAS might not be sexy - but it will increase capacity and reduce accidents.
    Most of the airports which need more runways do not have the room to add more runways. How many major airports east of the Mississippi are not landlocked?

    The complex fact is that adding runways does not linearly increase capacity. Unless you build a remote terminal you quickly switch the bottleneck from runway space to taxiway space. Every additional airside intersection increases ground delays and adds to control complexity.

  8. Killed by the little costs. on Houses With Tails · · Score: 1

    Repair costs for physical damage to said "trunk" could be costly. How many homeowner associations have a member competent in fiber splicing? Not to mention the difficulty in finding exactly where physical damage is located. A backhoe trench is pretty obvious, but damage on an aerial run pole-to-pole is not so obvious.

    It is easy to say 'homeowner is responsible for their "tail" and the association is responsible for the "trunk"', but who pays the expense of diagnosing every problem which comes down the pipe?

    What about one-call utility protection services? Most states in the USA have a one-call utility location service. You need to either register (and mark your own lines when called or pay someone else to do so) or accept that anyone digging in proximity to your lines will believe there are no obstructions. (and thus will not dig carefully.)

    Repair, support, service, damage prevention, and infrastructure hardware. Deal with these issues in a comprehensive manner and you're pretty much an ISP. What was the point again?

    Doesn't change the fact that the majority of American workers, period, work in an environment (be it a cube farm, a hospital, or be it a retail store) where the lighting is fixed and not under their control, much less affected by DST.

    Overtones are exactly the issue.
    One of the ways MP3 reduces the data is to remove quiet tones when there are louder ones of a similar frequency.

    Well, where I live all the street lights are automated to turn on when it gets dark out. If it's darker for longer in the winter, they'd run more. They don't care what time it is, if it's dark they're on.

  18. Re:What kind of music is involved on After 4 Years, HydrogenAudio Opens New 128kbps Listening Test · · Score: 4, Informative

    You are asserting MP3 has faults it does not have.
    "Overtones" are not an issue, nor do I think you could point out a 'problem sample' which fails due to the presence (or lack) of "overtones."
    Popular music, in fact, is often harder to encode efficiently as it tends to have the dynamics compressed out of it (see loudness war), full of distortion, and therefore be closer to random data.
    Temporal smearing is clearly a problem with MP3, and is evident in music such as harpsichord, but that is not the claim you make.
    Do you have any ABX tests to back your claim?

    good headphones are a must for such close listening tests. you'll only be able to hear really major differences with most speakers.

    Good headphones are nice in so far as they block ambient noise and allow you to hear any artifacts easier, but since MP3 is a perceptual encoder it is actually more likely that artifacts are audible on "defective" hardware.
    If a cheap speaker or cheap headphone's frequency response is bad enough to mess with the model's idea of masking, for example, poor quality reproduction can actually make the 'tricks' of MP3 apparent.

  20. Re:Households isn't enough on Daylight Savings Time Increases Energy Use In Indiana · · Score: 2, Insightful

    In order to really determine the effect though, they need to look at all power usage not just households. What about municipalities (street lights, water pumps, etc.), businesses, office space, Government offices, etc.)

    I've never lived in a city which turned off their streetlights for part of the night, so I'm not sure what consumption change would be possible there.
    Water pumps (I assume you mean the ones which lift water to the water towers) operate as a function of water demand, and I'm not sure how water consumption could be changed by DST.
    Also unfortunately, most offices and businesses use lighting in a manner which is independent of ambient light, so I'm not sure why we would expect a difference there.
    In fact, I would expect household consumption to be the most elastic and the exact market one would expect to see the most savings in (if there were savings to be found.) It tends to be individuals, not businesses, who turn on and off lights in response to window-provided light.
