Is this because nitrogen makes up most of Earth's atmosphere?

What frequency of ultrasound will most efficiently heat up nitrogen [N2] gas molecules?

Hi: What is the mechanism by which ultrasound generates heat? Thanks, Green Xenon

1. I do wish to install a dehumidifier in my house. The weather isn't of much concern to me. 2. The irritation you refer to is not a direct result of dry air -- it is because dry air allows existing dust and other irritants to move more freely than humid air. Humidity holds those irritating particles down. In this case, an air-purifying system [which removes pollen, dust, dander, etc.] can be installed to keep the air clean.

I thought I already answered that question. No offense. In any case, isn't it possible to use air friction or air compression to heat air to desired temperatures during winter? Or would those techniques be too inefficient to be used in practice?

1. I like to separate heat and humidity 2. Glycerin is just as bad as water 3. I don't like any radiant heating system that emits thermal radiation outside of the Infrared-C spectrum Infrared-C= 100,000 nm to 3,000 nm 4. I prefer clean, dry, hot, smell-free, smoke-free, irritant-free, dust-free, allergen-free, dirt-free air that is as hot as it can get without increasing sweat gland activity in the average human. The relative humidity of the room should be as low as possible. 5. The relative CO2 concentration in the room should be as low as possible.

Hi: I'm looking for an air-heating system with the following qualities: 1. No part of the system should produce any odor -- I notice many heaters give off a smell which distracts me from daily tasks. 2. No part of the system should generate any CO2, CO, or water vapor -- this means it cannot be directly fueled by gas or other chemicals. 3. No part of the system should require any water -- this means absolutely no hydronic thermal devices. 4. No part of the system should contain, produce, or use any toxic substances to any extent. What do you suggest? Thanks a bunch and Happy Holidays, Green Xenon

Hi: I recently posted something similar messages. I apologize profusely if anyone is annoyed. Infra-red C spectrum = 100,000 nm to 3,000 nm 100,000 nm = 2.9979e12 Hz = 2,997,900,000,000 Hz 3,000 nm = 9.9931e13 Hz = 99,931,000,000,000 Hz Arithmetic mean of IR-C spectrum = 51,464,450,000,000 Hz = 5825.23388 nm Due to the above and the inability of the device in http://www.scienceforums.net/topic/53451-wide-spectrum-irc-emission-device/ to exist, I'm now thinking of a free-electron 51,464,450,000,000 Hz laser for the same applications of that previous IR-C emitting device. In addition, the emission of the 51,464,450,000,000 Hz light from this laser is constant, non-flickering and non-pulsatile – in other words, continuous-wave. The shape of the laser emitting this radiation is square or rectangular depending on the application. In any case, the laser faces downward from the ceiling -- or other "top" -- of an enclosure and emits the IR-C light *downwards* only. My question is, what would be the disadvantages – besides the cost and bulkiness – of using this hypothetical free-electron 51,464,450,000,000 Hz for the applications discussed in http://www.scienceforums.net/topic/53451-wide-spectrum-irc-emission-device/ ? Once again, I hope no one is upset as a result of my messages. Thanks & Happy Holidays, Green Xenon

You know, I'm starting to realize that some of my preferences are unnecessary. Maybe coherence does not need to be avoided. In any case, how would one design/build a 51,464,450,000,000 Hz laser? I'm guessing free-electron laser is the best candidate for this. However, the bulkiness of the FEL might be an issue in the applications I described.

How can a laser's light be "de-coherenced" to the maximum extent possible? Ok, so I agree to make this device a laser. Happy Holidays, Green Xenon

Other radiation is ok as long as they are at negligible intensities. Due to my personal preference, I don't want to associate lasers with extreme or even perceptible heat. In any of my applications, I would like lasers not to generate any noticeable heat. So if something is going to be used to heat things up to significant temperatures, the source of heat should be something other than a laser.

Hi: I recently posted something similar. I apologize profusely if anyone is annoyed. Infra-red C spectrum = 100,000 nm to 3,000 nm 100,000 nm = 2.9979e12 Hz = 2,997,900,000,000 Hz 3,000 nm = 9.9931e13 Hz = 99,931,000,000,000 Hz Arithmetic mean of IR-C spectrum = 51,464,450,000,000 Hz = 5825.23388 nm Due to the the above and the inability of the device in http://www.scienceforums.net/topic/53451-wide-spectrum-irc-emission-device/ to exist, I'm now thinking of a different device for the same applications of that previous IR-C emitting device. This hypothetical device emits only 51,464,450,000,000 Hz light, not higher-frequnecy and not lower-frequency -- just 51,464,450,000,000 Hz. This light is incoherent and because of this, this device cannot be a laser. It cannot be a LED either because there are no LEDs which emit in light at 51,464,450,000,000 Hz. Even if they were, LEDs are meant for low-intensity emission. Forcing a LED to emit light intense enough to generate significant heat will damage the LED. In addition, the emission of the IR-C light from this theoretical device is constant, non-flickering and non-pulsatile. The shape of the panel emitting this radiation is square or rectangular depending on the application. In any case, the panel faces downward from the ceiling -- or other "top" -- of an enclosure and emits the IR-C light *downwards* only. Equally important is that the source of this light is *not* incandescent to any extent. The generation of this IR-C light is the result of something other than incandescence. By "incandescence", I'm referring to EM radiation being emitted by an object as a result of heat and/or temperature and/or temperature difference. Thanks, Green Xenon

What if, hypothetically-speaking, the temperature of the coils were somehow dropped to the astronomically-low temperature of the following degree Kelvin: a decimal followed by a Graham's-number of zeros followed by one 1 http://en.wikipedia.org/wiki/Graham's_number Now that is an one *extremely* low temperature! Would this result in significant radiant cooling of objects in the room?

Hi: I thinking of a radiant cooling device for houses and buildings in which the cooling -- in the direct sense -- involves only radiation. Sort of like a glass-ceramic radiant-stove-top in reverse. Indirectly, however, some amount of convection and conduction will be needed [liquid nitrogen, cold metals]. The cooling panel is the ceiling and cools objects below it. Quote from http://en.wikipedia.org/wiki/Glass-ceramic : "A glass-ceramic stove uses radiant heating coils as the heating elements. The surface of the glass-ceramic cooktop above the burner heats up, but the adjacent surface remains cool because of the low heat conduction coefficient of the material." Here is an example of a radiant stovetop switched on: http://www.istockphoto.com/file_thumbview_approve/4799702/2/istockphoto_4799702-glowing-ceramic-stove-top.jpg My theoretical glass-ceramic radiant cooler is similar to the infrared radiant stovetop described in the wikipedia link, except: 1. It faces downward 2. The coils are hollow [as opposed to being solid all the way through], this hollow within the coils allows liquid nitrogen to flow through them can cool them down to near absolute zero 3. Liquid nitrogen -- not electricity -- flows through the coils. 4. Obviously, the coils get cold instead of hot. The radiant cooling panel is on the ceiling of the room it is supposed to cool. Those standing under it will feel cold. Yes, heat absorbed into the radiant cooling panels is carried off using convection and conduction -- but this is not what the subject inside the room feels. The direct cooling effect on anything/anyone inside the room is radiant. By direct radiant cooling, I mean that if you place your body at a noticeable distance from panel, you'll feel cold because the extreme cold of the coil will draw IR radiation away from your body. I’m thinking of more intense versions of this hypothetical glass ceramic radiant infrared cooler to be used in refrigerators and freezers. This radiant cooling is something that I am deeply interested in. I don't know why. Radiant cooling will feel to the object like "cold rays" just like radiant heating feels like "heat rays". I know there is no such thing as "cold rays", it's simply heat radiating from my body to a colder object. My body is giving of heat rays causing it's temperature to lower, thereby giving me a perception of coldness. To prevent water from condensing on the panel, a separate air-dehumidifier is used. Thanks a bunch, Green Xenon

Hi: See page 1071 of http://books.google.com/books?id=nauWlPTBcjIC&pg=PA1071&lpg=PA1071&dq=portuguese+man+or+war+hypnotoxin&source=bl&ots=oOEifavQUD&sig=hKu2ipDhkWuB8bk59gnTa_-m4RA&hl=en&ei=6GIMTYrWEYnGsAOZg7WiAg&sa=X&oi=book_result&ct=result&resnum=2&ved=0CBgQ6AEwAQ#v=onepage&q=portuguese&f=false The Portuguese Man of War jellyfish produces a neurotoxin called "hypnotoxin" which depresses the central nervous system of humans and causes sensory/motor malfunctions. Where can I find more information on this hypnotoxin? In particular, what is the maximum non-lethal dose for the average adult man in his late 20s? Thanks, Green Xenon

What is the closest possible device to the hypothetical one I'm describing? Wavelengths outside of the IR-C spectrum are dangerous at the intensities required to have a heating effect. At frequencies lower than IR-C, the radiation starts to resemble RF which can heat internal body tissues to unhealthy -- and potentially hazardous -- temperatures. At frequencies higher than IR-C, there are also unhealthy effects. For example, IR-B can cause aqueous flare in the eyes. IR-A can damage the retina similar to wavelengths of visible light at the high intensities needed for warming the skin.

It is superior in the sense that it maintains the purity of the IR-C spectrum.

What makes it impossible?

Hi: I'm currently thinking of a hypothetical device that emits a spectrum of EM radiation with a maximum wavelength of 100,000 nm and a minimum wavelength of 3,000 nm -- as well as any and all wavelengths in between. This is known as the Infrared-C -- or IRC -- spectrum The intensities [i.e. photons-per-second-per-square-meter] of light emitted are equal throughout the spectrum, no one wavelength is of greater or less intensity than another. This hypothetical device does not emit any wavelength of EM radiation out side of the IRC range. In addition, the emission of the IR-C light is constant, non-flickering and non-pulsatile. The shape of the panel emitting this radiation is square or rectangular depending on the application. In any case, the panel faces downward from the ceiling -- or other "top" -- of an enclosure and emits the IR-C light downwards. The IR-C light emitted is non-polarized and incoherent. Is it physically-possible to construct such a device? If so, does such a device already exist? If it does, where can I find it? I’m thinking of three applications for this theoretical device. Depending on the intensity, this IR-C could be used simulate a sunbathe, to carbonize human feces [in a septic tank], or to broil food. In the case of the 'sunbathe', the maximum intensity of the IRC light should result in the maximum temperature one can experience without any discomfort or injury to any extent. This IRC light makes you feel like you're basking on the beach when the sun as at its highest point [~ 12:00 pm usually]. For the broiler and waste management [of human excrement], the max. intensity should result in a temperature that’s just high-enough to reach the smoking point [carbonization temperature] of the organic material with the highest smoking point. Substances with carbon and hydrogen will emit smoke when heated to the smoking point. Different organic substances have different smoking points. Many foods taste better with a little bit of smoke. I like my cookies slightly burnt. For basking, this lamp should be on the ceiling of the room it is in and emit downwards to the person inside the room, to give the actual feel of sunbathing. I’m relaxed just thinking about this basking room. For broiling, obviously, the cooking is from the top. Same for carbonizing human digestive waste. The burning is done from the top. In addition, for broiling food and managing human colon waste, all oxygen in the broiler [or septic tank in the case of the latter] is removed to aid in the smoking/carbonization process. Following this, the broiler/septic-system is sealed for air-tightness and the lamps do their work. Unlike for broiling food [where only top of the product is carbonized], the septic tank completely carbonizes all the organic compounds in the feces throughout. Again the IR-C emitting panel is on the top of the septic tank and when the tank is full, the tank has all it’s oxygen removed, the tank is then sealed [for air-tightness], and the IR-C lamp panel turns on to max intensity to convert the waste into smoke and carbon. The septic tank is kept closed and sealed until what used to be crap [literally] cools down to a temperature safe for human handling. Thanks, Green Xenon

What does "CV" stand for?

Hi: I'm thinking of a theoretical device that could be used as an air heater for the home. This device emits a wavelength of EM radiation that is best absorbed by nitrogen. This causes the N2 molecules to heat up. Since the air on earth's atmosphere consists largely of nitrogen, could such a device be used to keep a house warm during winter? As air is pumped into the house from outside, it passes through this device, absorbs the radiation and gets warm. Finally, the air enter the rooms through the vents. The advantage I see to such a device is that it wouldn't cause the house to have the classic "heater" smell. What would be the disadvantages -- excluding cost -- of such a device? Could anyone suggest something better? Thanks, Green

In my opinion, the drawbacks of this product sure beat suffering the following in your early/mid 30s: 1. Being weakened by a heart-attack 2. Paralysis/blindness from stroke I'm dangerously overweight. My cardiac CRPs and blood-pressure are through the roof and I'm only 27. That is why I need this product. I don't want to end up handicapped 5 to 10 years from now, and that can easily happen due to the absence of this product. Exercise is not enough. I badly need this product.

Why expensive?

Hi: I’m currently thinking of a hypothetical diet product that is vegan-friendly and has all the vegetables, fruits, herbs, algae, seaweed, mushrooms and other non-animal organisms that are necessary/beneficial for human health. It also contains beneficial and essential microbes [such as probiotics]. All the aforementioned are in amounts optimum for human health. This product is completely organic and free of any pesticides, synthetic ethylene and other man-made substances that compromise the health of organisms and their human consumers. In addition, no organisms used in the product are genetically-engineered, pasteurized, or irradiated to any extent. Equally important is the soil and other conditions used to grow these organisms is healthy, organic, and free of pollutants. All organisms used in this product are raw. No substance in this product is altered at all. No existing substance in the product is removed. No substance, other than drinking water, is added to this product. The product has drinking water added to it to make it easier to drink. This product is in small health-friendly, eco-friendly bottles. Five bottles per day should be consumed. The bottles are in a package and are of different sizes. The biggest bottle should be consumed in the morning. The smallest should be consumed in the evening. In between, are bottles of different sizes. Earlier in the day, the bigger bottles should be consumed and as the day progresses the smaller bottles should be consumed. This routine follows the saying “eat breakfast link a king, lunch like a prince, and dinner like a pauper” – except the food is divided into 5 smaller meals instead of 3 bigger meals. This is an extra benefit to diabetes patients who are following this hypothetical diet. To summarize, the organisms in the product are chopped to the molecular level. Finally, good microbes and drinking water are added. Regards, Green Xenon

Wrong. When carbs are not available for energy, the body switches to fat for calories.
