  1. Re:Voltage Spikes on Why Power Failures Can Always Lead To Data Loss · · Score: 1

    and not even grounded at all.

    Every working small-dish is grounded, if they didn't bond outside or place it on a metal surface, then yeah the receiver is providing the ground, very bad if the dish builds a sudden charge (lightning lights up the coax cable.)
    Definitely SAT gets a much better signal, with a better ground. However to best protect the people/equipment I would think you would want something else to be your lightning rod. IE another structure higher up, with a better ground. Making your sat the best grounded path just intuitively seams like something to avoid when lightning is around.

    voltage problems cleared up after I added an 8-foot vertical ground rod to the system.

    Living in AZ, I can tell you all our radio towers, after installed, are then prepared with a large bag of salt then soaked deep into the ground with several waterings to get this good ground (and repeated every few years.)

    However you should realize that current takes the path of least resistance. So by having the best ground path, I hope you have the best surge suppressor close by (IE not a 100' of 14G ground wire away from your ground), cause more of any surge is now coming your way (IMHO). The earth ground is mostly their to protect people, not equipment. IE if your computer has no earth ground path nearby, it wont care if their is a brief 1000Volt offset between earth ground, and the computer ground, as long as the computer ground, and line stay 120Volt apart. Now if a person is touching a metal desk, touching the computer, your body has a capacitance that would love to be charged by any spike... So having the best ground, will make your house safer for people. But may make your house the "lightning rod" of the neighborhood for your electronics.

    you're pushing lots of electricity to the grid during the day and pulling a lot at night.

    currently power generation is more valuable during the day, because thats when it is most used (especially in A/C dominated CA.)
    That is the likely reason for a retail price compensation OK for solar generated by day. The solar is likely displacing more pricey natural gas, for cheaper coal/nuclear. Also possibly reducing net line load from the factory during peak draw...

  5. Re:huh? on 12,000 Laptops Lost Weekly At Airports · · Score: 1

    the wording (didn't RTFA) may add some belief. I have lost a laptop in the airport and never recovered it. IE, the screen broke (usefulness gone = lost) It was never recovered (all data was backed up+cost more to repair than a new one) so I never recovered any thing.
    More dead from use than lost/stolen seams likely to me.
    If 600,000 laptops were stolen by travelers from travelers, it is clear most laptops used by travelers must already be stolen once. Therefore I can only conclude that only a few hundred laptops are stolen from their legit owners per year, the rest is just thief on thief crime.

    with a phone running Skype for Mobile or practically any VoIP...

    the trick was "switching" the only way I can think of to do this, without telco support, is if you were to call a sip provider first, for all GSM calls, and they proxy your call to the final number. Thus when WiFi comes available your sip provider gets the SIP session started, and drops the GSM call. To switch back (if trying to save GSM minutes) I would assume it would need to see the WiFi getting weak, and call on GSM, before the WiFi call was dropped, again calling the SIP capable proxy, not the end number.

  10. Re:Wasting power on DIY Solar Resources? · · Score: 1

    I would add couple things (that will out cost AC, currently):
          1) DC has the advantage of a simple capacitor can handle startup surges, they can be spread around easily (don't need the wire sized for the surge then.)
          2) You can run higher voltages of DC, split up your battery banks/solar cells to stack appropriately. 85% efficient 96Volt to 12 Volt @ 30 amp are available. They waste no energy during no/low load situations (AC inverters that shut off are becoming available, but can be a pain) If 96Volt DC devices became high volume, all the arguments you post disappear (except I am back to needing a permit for "high voltage" wiring.)

    I would add, that although their efficiency is horrible, using air powered drills is the convenient way to go. IE my 3/4 Hp 1/2" air drill, weighs less than any 1/2 HP AC drill, has more torque, and the hose is not that much different than the AC extension cord. The expanding air, cools the drill keeping it much cooler. Except that it takes a 5HP motor at the compressor to run a 3/4 HP motor. (If I can just figure out how to solar power enough stored air, then their will be little need for AC in the shop.)

    I wasn't too impressed with that document, a little light on sources, and presented in a manner to twist the math even though thats not necessary.
    More importantly that math only applies to grid connect systems, this question is about a building with no grid power, and light power demands. I bought a 45 Watt system from harbor freight, for $120 only missing a battery, has 12 Volt lights, controller, etc. For a 120 V solution, I would need a $100 permit, $80 of wire, to get inside the building (next to my house with grid power.) A property with no existing grid power system to backbone off would be out thousands of dollars to connect, then a minimum monthly payment of maybe $20 for life.

    You pretty much summed up harassment, since it is defined by what bothers others. It is treated equally when complaints are filed. IE men never complain about harassment (and trained by society to not complain about these type issues), so their opinions don't merit the same consideration (because were not bothered.) Of course in practice complaints by guys are treated differently, but that falls outside of the 99% of harassment complaints.

  24. and biodiesel != vegetable oil on SwiftFuel Alternative To Alternative Fuels · · Score: 1

    I think the confusion is the relationship of vegetable oil and biodiesel. And that it takes methanol, and lie (to correct the acidity of the vegetable oil) to convert from vegetable to bio-diesiel. of course the methanol is a catalyst, so then you can either directly sell the by-product, or add energy to get back your methanol.

    Also I don't think all diesel engines are good donors to be converted to the burning of vegetable oils (or even mixes of vegetable oil.)
    I know of one person who was mixing just 2-3%, but without correcting PH of the used oil, it burned the valves (I guess the different viscosity is important too.)

    my only point is, complete DIY solutions are risky, unless your really though in your research. And professional solutions are expensive, to the point of being barely worth the cost.
