Thanks for the video. It would be really helpful to have another vid where
you go through one typical PE problem using the per-unit analysis. I find
this to be one of the most simple yet frustrating topics on the PE.
these videos are helpful although you never showed how to work out the
actual per unit values, just how to get the bases

How to Use a TENS Unit to Relieve Muscle and Joint Pain
A TENS unit (Trans-cutaneous Electrical Nerve Stimulator) is a small device about the size of a deck of cards that can be used for managing sub acute or chronic ...
"somehow modulates the sensation of pain"... *every* intervention into our
nerves is bad. Especially when you electrically stimulate an area of your
skin. This does not only affect nerves that need to be affected. It also
affects a number of other nerves including those that go to other organs.
Including brain. It's really sad how stupid the "scientifical" community is
nowadays. How naive we are to think that this kind of stimulation does not
affect other vital parts of our body? Incredibly naive.
+brians153 one more thing. I'm always amused by guys like you. Guys who eat and do everthing that is "science based". And then I read official data (CDC articles and HBS articles) which clearly shows that medical drugs are the third leading cause of death in US (properly prescribed!). Weren't these drugs supposed to help us? And here I ask the question (no, I do not want an answer from you). Are you people still gonna be so naive to think that all of this stuff is harmless? If you want to use it (for an extended periods of time) then be sure you never want to have children in the future. Otherwise they will be affected. We have never had such an outbreak of brain damaged newborns as we have now (governemnt data again). And doctors do not know why. Of course they do not know! Nobody knows why, because we simply know too little about human being in general. Don't be naive people!
+brians153 hey troll. We have been offered a number of stupid "inventions" like this in the past. All of them were supposed to be safe and effective. They turned out not to be safe and effective. If you want to fool yourself then just continue doing it. Scientists do not know how brain works so whatever they do with the nervous system is just an experiment. Deal with it. I can understand your reaction if it helps you with your pain problems. OK. But don't cry in 10 years from now when they find out that TENS was bad. That your genome has changed. That you can not have more children. Because guess what! Genome changes depending on external stimulation. We have never had such a great number of people with external electrical stimulation. So we are about to see how our bodies are going to adapt to this. Genome changes pretty fast. You should be able to see results in next generation. They may become unable to deal with pain at all or something like that. The result of this experiment will be understood in the near future.
+plmareksurma you are a dope. you have no clue what you are talking about. its really sad how stupid YOU are. You should leave the internet and never return. You jackass!
What is the brand you are using? i have bulging disc in my L4-L5 and in my
S1 degenerative disc disease there. I also have muscle spasms going down
my left buttock and some spasms in my calf muscle. Its not my sciatica I
have went to therapy and use theirs but its only 2 times a week. i am
having my second epidural Tuesday. I use cold instead of heat. I am
looking for a great one that will last a long time and one that will be the
best... thank you for this video
+Katie Khou TENS units can be bought online directly by the consumer. It is best, though, to have a doctor specializing in sports medicine or physical therapist to show you how to use one before you try it yourself.
Homemade Air Conditioner simple DIY AC uses 45 Watts - can be solar powered!
make your own air conditioner with a fan, copper tubing, clear tubing. small fountain pump (158gph) and ice water. cost $30. 45 Watts. can be run using "3 panel ...
This would work better in a humid place. The problem lays in the details
though. The conversion is about 4 amps. Add the ice and now you burned the
approximate same as you would have, had you ran a small 9000 btu ac.
All of your bravada about your qualifications do not reflect the change in my power bill and electrical usage. I have more $$ in my pocket this July than I did last year including a rate increase on power. I repeat the 18000 BTU AC unit I used sucked between six and seven times the power of my energy star rated chest freezer at everyday use. Obviously constantly refreezing four gallons of already near freezing water in a much cheaper operating chest freezer while running two 18 inch fans and two aquarium pumps takes less energy than the AC unit used to lower AND sustain the ambient air temperature in a 1000 square foot apartment with 8 foot ceilings. I like to keep it 65-70 degrees at all times. Last year with the same climate my June power bill was $158 with the AC. This year with these units, using insulation on the plastic tubing and water tanks it was $93, but by all means, please tell us all how that very real 63 extra bucks in my bank account says I'm wrong again and how I need to reconsider my position.
+Jim Piper Jim... I will show you as to why I will stand behind my comment.before that I will make one fact known to you and those reading... I am refrigeration expert. I hold my operating engineers license here in NY. I have worked in most of the skyscrapers at one point or another in my career, yes even the late Trade Centers. which were ocean water cooled. my resume is sick. let me show you something. You would need to remove approximately 1200 BTUs of heat to convert a gallon of water to ice. (if the water was already 32 degrees - liquid) There are 8.34 lb in a gallon of water, which converting to lb-moles is 0.463. The latent heat of crystallization for water is -2583.4 BTU/lb-mole. Multiplying the two together and you get -1197 BTUs, which means you need to remove that amount of heat to convert the gallon of water to ice. Now... Cooling food requires a considerable amount of energy, which means that a refrigerator adds significantly to your monthly electric bill. According to electricity expert Michael Bluejay, the average refrigerator uses 488 BTUs per hour in normal use. If you put something especially warm inside the fridge, it must work harder, consuming a greater number of BTUs hourly. (this is cooling only, not freezing).so... to keep it simple... and not have to do a heat load calculation right here on google plus at 8 in the morning after a nights worth of drinking... lol - lets do this instead... take 1200btu's ideal and divide them 488btu's... you would get the result idea of how long that compressor would need to run to make that "ideal" water into a solid brick of ice. then multiply it by two... for your two gallons. I get 12000/488x2 = 4.91 that's five hours of compressor time, evaporator motor time and condenser fan motor time. now take that 5 hours of ideal temp water to ice cooing... and multiply it by the average amp draw of a domestic refrigerator... which is about 8 full load amps, divide that to your electric companies kilowatt per hour charge and you will have a ball park of what this truly costs just to make the ice... if the water is already 32 degrees! if its tap water at say 70 degrees the cost goes up! then add your fan wattage per hour to run... plus your salt pump per hour to run. at this point if you do your specific areas cost in the very crude way I have laid it out above... you might reconsider your position. lastly.... there is a much more efficient way to run this fan coil cooling contraption... but it requires either a hole in the ground or a body of water close by. similar to a pond, lake or pool.here are some basic links for you://www.answers.com/Q/How_many_BTUs_will_it_take_to_change_1_gallon_of_water_at_32_degrees_to_ice_at_32_degrees//www.ehow.com/info_12160135_average-btus-refrigerator.html
+birdman3931ny I use two of these modified with insulated salt water foam coolers and frozen gallon jugs of water. They fully replaced my 18000 BTU window AC unit and cost me $50-55 less a month to use.
We haven't had really high temperatures so maybe not. I can deal with heat, but the humidity makes me feel like a fat girl running up a hill! Damn!!! LOL!!
+Ioanna*Warrior4YHWH. Nothing like Ny. Trust me. Lake Murray sends that flat breeze! The pine trees and cedar trees cover the sun well. Not that's its not hot as hell down there... by it ain't nyc hot. Lol no trees here. Smog out the ying Yang. Lol better off south and dry, than north and sticky.
