Thank you. A patent gives the right to $ue, if pockets are deep enough. A patent lasts 3, 5, 10 years of whatever. Preventing from patenting will last forever... I think.

Thanks. Am not trying to avoid the fees, or patent myself. Just trying to prevent it from being patented by anyone. Your link helped finding this, and websites are listed :

Hi all. If I publicly display/explain a new product, idea, design, prototype, application, demonstration movie of its operation in a forum or this forum or anywhere public site on the web; would that prevent from being patented by anybody else, as becomes public knowledge 'existent since the date of disclosure' ? My patent lawyer explained something in that line a loooong time ago. Would it be effective ?

And I wish to understand English ... What is semi ? A partial or half something truck ? Who comes up with those words ?

This has to be a good question. Hope some experts will bring light. Reminds me of when I was asked what surface would an adhesive be applied, and others said plastic. Actually was epoxy paint on plastic, and that is the material the adhesive should be formulated instead. And when choosing furniture cleaners, picking the one for wood. When the wood is actually sealed under layers of clear varnish. The cleaner has to be for varnish, not for wood. And selecting sandpaper for metal, for a car body... Actually the sandpaper will work against old paint, fillers, not much on metal...

Will this type of solar cell crash against a RoHS brick wall even if results in a good, convenient, efficient and cheap development because contains lead ? Or has it already been discarded/discouraged as solar cells production alternative ?

Thank you, gentlemen. From the link in post #3, can you please check if am translating properly " Survival and activity followed a clear wavelength dependence, being highest under UVA and lowest under UVC. "? As highest survival of germs on UVA (400-320 nm) and most damaging/impairing/lethal on UVC (290-100 nm) ?

For a particular germ, there may be a particular ultraviolet wavelength that is more effective for disabling/killing it. What is known about exposure times ? Is it in the seconds, minutes, hours ? If using a wavelength that is not optimal for a particular germ; what is known about effectiveness by lengthening exposure time or increasing intensity ? Edited. found 10 seconds to be effective. Surprisingly short time. But does not specify when wavelenght is shifted. "The exposure of germicidal ultraviolet is the product of time and intensity. High intensities for a short period and low intensities for a long period are fundamentally equal in lethal action on bacteria. The inverse square law applies to germicidal ultraviolet as it does to light: the killing power decreases as the distance from the lamps increases. The average bacterium will be killed in ten seconds at a distance of six inches from the lamp. Ultraviolet light in the germicidal wavelength - 185-254 nanometers - renders the organisms sterile. When organisms can no longer reproduce, they die."

The shades from people does not match the triangle shade. More crap-filled internet.

What aliens?

Thanks, gentlemen. I take then that radon dosimeters are not radon gas dosimeters but dosimeters for radiation from radon decay.

Is there any tiny bit of this that can be real ? ----> http://ireport.cnn.com/docs/DOC-488531 ----> https://en.wikipedia.org/wiki/Black_triangle_(UFO) ----> https://www.express.co.uk/news/weird/679732/EXCLUSIVE-UFO-SENSATION-Could-amazing-footage-be-first-video-PROOF-of-mysterious-TR-3B ----> http://www.military.com/video/aircraft/military-aircraft/tr-3b-aurora-anti-gravity-spacecrafts/2860314511001 ----> https://archive.org/stream/TopSecretTr-3bAstraDocuments/Tr-3bSightingsPictures-ThisUfoSightingWasCaughtInParisFranceVideo_djvu.txt

In different units. Showing the exposure to its radiation, but not the amount in air (correlates?)

Hi John : 'Sniffing' meant as a method mechanically passing air trough a discerning physical/chemical/spectral/... sensor chamber/duct that could detect radon regardless of its radioactive emissions , in opposition of sensing only presence of radioactive emission alone and assuming comes from radon, with no air/gas flow into a sensing chamber. This one shows "unaffected by other radiation" ----> https://airthings.com/wp-content/uploads/2017/12/Home_product_sheet_US.pdf The metering reports radioactivity as pico Curies per litre, perhaps some show as Bq/m3; not parts per million concentration in air.

Here is a few. Perhaps each works on different principles ----> http://sarad-radonshop.com/doseman-radon-exposimeter-dosimeter?language=en ----> https://www.cphklima.dk/produkt/kodalpha-dosimeter-radonmaaling-sporfilmsmetoden/ ----> http://www.englo.eu/en/products/toode/radiation-measuring-devices/radiation-mesuring-device-radon-3-3/ By coincidence, the 'sniffing' word I used is also at this site ----> http://www.mearec.ch/radon-messung.php

Radon dosimeters work by 'sniffing' the air or by measuring its signature radiation ?

Sunlight after a prism, with several equal solar cells placed to receive each of the colors individually... Which color produces more energy ? Should depend on the spectral response/sensitivity of the cells; but is there a color yielding more energy ? Ultraviolet ?

I receive my television on 12GHz. Think of a distant light bulb that has to illuminate an immense area. Not a narrow beam directed only to your reception antenna. The transmitted power from the satellite is spread so thinly to cover a huge area, that the reception signal level is faint at your location after propagating thousands of kilometres. Additionally, if you place obstacles in the signal path weakens the signal even more to the point of being less than the receiver sensitivity. Your 'radio' stations may be much nearby yielding a stronger signal. Some electromagnetic frequencies are also subject to attenuate, bounce, fade more or less than others.

Hello. The wave of a half submerged in water loudspeaker is received by a dry microphone as 1 Pascal sound pressure level SPL. Its diaphragm vibrates say 0.01mm in amplitude. The wet microphone diaphragm should vibrate a larger, same or smaller amplitude ? (Both microphones equal, equidistant and vented)

Thank you. My searches did not show results for space/room heating. Medical and food warming pads are far from room heating capabilities.

Is there such thing as an exothermic heater in the market, perhaps based on quicklime or similar, for indoor emergency heating as in electrical power outage; instead of propane heaters ? Something safe to health, that when activated/started will heat up with no combustion gases. I have small chemical something warmers for the army, that with water added produce heat for a limited number of hours. Some are reactivable by heating in an oven, allowing reuse. Something in that line of products, instead of :

Which could be the proper materials used here ? ----> https://www.evolving-science.com/intelligent-machines/moisture-powered-microbots-korean-researchers-demonstrate-how-humidity-can-be-used-energy-00559 Play the video in it, it is interesting...

Here is one 'expert'. Is it the wrong-hand tool/user ? I found several pictures doing it wrong; including the picture on the box of mine (bottom image). At least am not the only goofy.

Always found my circular saw to be awkward to operate. Is it because there is left and right-hand types, with no markings on the box, depending on the buyer to recognize it right away ? Have goofed too long time to notice it... Pictures borrowed from the web; top seems right handed.

If translation is needed, just ask...
