  1. A zillion years ago, about 8th grade in school, the teacher was demonstrating something and put water in a vessel to boil on a bunsen flame. He placed a glass/mercury thermometer inside to show the reading. I was the only one who warned the teacher that could not the correct way to measure the water temperature, as the thermometer bulb was contacting the bottom of the vessel and would read higher than real water temperature. Then he held the thermometer by hand suspended, touching only the water with an embarrassed red face. Now am thinking if I was wrong. Would the vessel be at the same temperature as the water contacting in it, or would the vessel be hotter as I pointed because it was contacting the flame; or somewhere in between (Which would still be a higher reading) ?
  2. Clear ! Thanks. Then, if in cold air induction A + fuel B, we partially replace some A with some 'E' (exhaust gases recirculated into the intake), the fuel amount B can be reduced accordingly to the amount of oxygen as the amount of A is less. Some amount of E + less mass of cold A + less fuel B ---> E + C CO2 + D others The amount of E, controlled by the engine control unit ECU depending on the ambient air temperature sensor reading. Is that the way it is currently implemented , or exhaust gas recirculation EGR is used only to reduce emissions with no intention to compensate for extra fuel consumption in cold air temperature ?
  3. Thanks. Well, then, comparing same exact driving/road conditions, will winter cold use more fuel than hot summer ? ( having no fast valve closure implemented )
  4. Seems you have not checked / searched for existing equipment, like negative ion generators. One of dozens in the market : http://www.the3q.com/products/3Q-ELECTROSTATIC-IONIC-AIR-PURIFIER-w%7B47%7DDUST-COLLECTION-ROD.html And the chinese production : http://www.alibaba.com/showroom/air-purifier-ionizer-dust-collector.html I unplugged mine as the area around the wall outlet got blackened with dust particles
  5. It's been about 20 years since they do not manufacture automobiles any more; they make computers with wheels since then. The on-board engine control unit measures intake air mass by its flow and its temperature, and sets the fuel amount for combustion. Being cold winter air more massive, does it feed correspondingly more fuel then, than in hot summer thinner air ? If yes, preheating intake air would decrease the fuel ratio, If not, is it because the oxygen content exhaust sensors action ? Hey ! but if there is more air mass intaken, then the 14:1 ratio could not be sustained ! What am I missing ? Is the throttle position working less open in winter for the same performance, or there is another compensating control ?
  6. Smile now ! - as tomorrow will be worse... Shifting labor into manufacturing robots labor will not suffice filling unemployment, and that is if building the robots does not move to China to make it really worse. Corporation greed will always push towards less expenses and more profit by selling crappier-short-lived goods, if 'goods' is the right word.
  7. -- When there is cold weather as in winter, does the atmospheric pressure 'shifts' to a higher range than in hot summer for the same clear sky ? It would make sense, as there is denser atmosphere when cold. -- When the weather reports say as example 'northwest wind' ... do they mean coming from northwest or heading towards northwest? Is there a standard meaning ?
  8. What is not recycled they want it burned ? Hospital refuse ? What else ? The volume of such for the $ amount of such incineration plant does not click well. Let the risky refuse producers install / do their incineration with their $ and do not put the hand in the taxpayer wallet; that money can be better used. Extending recycling to a finer point should be the choice.
  9. There is detergents for clothes washing, general cleaning, dish washing, hand washing, 'shampoos', body wash, car wash, and whatever the industry can come up with to sell more. How much of it is marketing, what forbids to use dish washer products for clothes washing, or shampoo for washing hands - between extremes; as obviously one ihas to be better 'tuned' to one application than another. In the fifties, shampoo barely existed, nor dishwashing machine fluids, and less the 'bodywash' they came up with. Do their surfactants differ that much ? Is there an optimal proportion of water to say -clothes detergent- that works best, or using more will clean more ? There is a trend to use double or more -than-suggested per laundry load. I believe that will only increase the perfume content of the washed clothes, but not the 'cleanliness' . Is that the way it works ?
  10. Which are those foods that produce adversion to you ?, from unpleasant to nausea -----> But not allergy triggering- Mine are Cauliflower Milk Butter
  11. If you tried all coatings/barriers and still unhappy, give silicone bakeware a chance. Perhaps it will work for your desired standards.
  12. Highly doubt anyone here is an astrology believer. And; astrology is not a science.
  13. Hi peon. I find your post very interesting, for black waters only. As stated, the main problem is the sedimentation and organism growth in the seawater intake and distribution pipes for household seawater distribution, which would be needed in parallel with existing potable water. A parallel salty sewer would also be needed because the 'purified' salty sewage ends in rivers that may be the source of potable water later, and salt content is very undesirable in fresh water bodies. The treatment of sea- black water (toilet) may not be much of a problem, as passing electric currents in the sewage plant would kill 99% + of undesirable microorganisms in it, and could be treated by some technique. Grey waters (kitchen, bath, laundry) would become a much less volume to treat, or can be used for garden irrigation and farming with just some filtering.
  14. As I was not able to post there... That very annoying smart vacuum cleaner is not that smart... ---->http://www.youtube.com/embed/xWMkOwq2qIU?rel=0 Enjoy !
  15. Thanks, will try s l o w l y, tomorrow and next day; and will let you know Have a good night.
  16. Hi CQ60-419WM I have not made any discs. As not always initializing, is that something that can be done from the BIOS screen selections at turn on ? If yes, idiot proof instructions from you would be better. I can tackle electronics, but compfusers is another story Thanks
  17. Unfixable wires... well... The ill C: drive is 250GB, over 230GB available (free) The external archiving USB pluggable drive is 400GB, about 300GB available (free) And I have half a dozen clean 200GB drives available to be installed in that external USB drive box. Recovery drive ¿? or recovery partition? unsure. Whatever is typical for such, as a guess.
  18. Thanks. Yes, I have a USB connected external SATA drive with NO operative system, just for data archiving. Is your laptop dead because does not respond to the charger ? I may help you there.
  19. Hi. Compaq Presario CQ60 laptop running Windows Vista Home Basic. Its Western Digital WD2500BEVS hard drive is failing by its 'smart data' report, and before dies, want to buy new drive and reinstall same legal and valid operative system. Have no discs from such laptop nor from Microsoft.
  20. Thanks, StringJunky. It is the drive self test 'smart data' ; a warning on number of allocated sectors. and to expand, it is Windows > Vista > Home > Basic version. I will slowly digest your guidance and see if I dare . Will let you know at some point about success or failure (of my skills)
  21. Hi. The hard drive in my other rarely used compfuser is failing. Does not end loading... Cannot 'extract' the operative system. The data I do not care, has been regularly backed and have it safe. The web is filled with instructions on how to backup the data for hard drive replacement, but cannot find what am asking here. Replacing the hard drive with a new one, how to reload/reinstall my very legal Microsoft software copy that came installed with it? Never got a CD with the operative system when I bought it. It has the Microsoft sticker with the bunch of numbers. Seen it done somehow at PC service shops, but never paid attention. Think it was via internet, but cannot get to it with a blank hard drive. What am missing ? Thanks god I run Linux here...
  22. By time stamp 1:12 on, at -----> Is that way to handle and process lithium metal 'normal' and safe in the industry ?
  23. Since at least 20 years ago, every time I needed to loosen rusty anything, works great ! Pour both in a container and shake vigorously, applied immediately before settling. Edited - added : You got me curious... Just checked wikipedia for Acetone, before the 'Safety' paragraph. And surprised of the Google hits on "transmission fluid acetone" Edit 2 : 30 years ago, I used 'Marvel mystery oil' My household "3 in 1" can refilled has only ATF in it. I use it for lubrication too, and as a wood furniture surface rejuvenator - Without the acetone !
  24. Uniformly creation of rust under equal torques is one of those things that may work well in the laboratory and papers, but the real penetrating fluid evaluation should be outside in the real world. I would go to a seaside marina or industrial plant and look at their junk piles, take your time looking for old equipment with many equal rusty bolts -say a boiler- to perform your tests. Am sure that someone there would appreciate the 'free' dismantling of some old stuff around. By the way; you want an unbeatable penetrating fluid ? Plain transmission fluid + acetone 50/50. I never buy that WD something nor any other 'liquid wrench' products. Penetration ability and rust 'freeing' are different properties of a fluid, if a bolt head seats hermetic for the applied fluid to reach past it into the threads, tests can be of uncertain effectivity.
