Talk:Radiant energy

message: The article refers to nuclear fission in the sun, but might be more correctly fusion.  Correct? - KitchM (talk) 07:23, 12 October 2010 (UTC)

message: Reddi, please don't just revert blindly. Whatever the merits of the image, the phrase "disinfect our beddings" is not proper English, and you keep reverting to it. Blind reverting without thinking is not acceptable, and is a typical symptom of edit warring. The use of first-person pronouns like "our" is also discouraged on Wikipedia; it isn't the right writing style for an encyclopedia.
I haven't looked into the patent the image came from, but I'm inclined to remove the image as well. It's over a hundred years old, and the invention does not appear to be of any practical value, in that we don't make light-powered devices that way today. It doesn't illustrate an "application" of radiant energy; merely somebody's outdated idea for a possible application. I wouldn't necessarily call it "crackpot", as Wtshymanski has, but it just isn't sufficiently relevant to be included in this article.--Srleffler (talk) 01:30, 20 January 2011 (UTC)
thread_title:  Edit war over Tesla patent image 

message: I removed the two lines:
"
Radiant energy comes from a glowing heat source and radiates in all directions.
Radiant energy is used to dry clothes, disinfect bedding, or diagnose diseases.
"
I gather from the discussion above that the use examples has been discussed earlier. Use examples should not be in an article like this and if it should be anywhere it should be more extensive. For the first line.. Well it is an oversimplification and misplaced. Larkuur (talk) 20:45, 1 July 2011 (UTC)

===Applications===
Radiant energy, as well as convective energy and conductive energy, is used for radiant heating. It can be generated electrically by infrared lamps, or can be absorbed from sunlight and used to heat water. The heat energy is emitted from a warm element (floor, wall, overhead panel) and warms people and other objects in rooms rather than directly heating the air. The internal air temperature for radiant heated buildings may be lower than for a conventionally heated building to achieve the same level of body comfort (the perceived temperature is actually the same).
Various other applications of radiant energy have been devised.Class 250, Radiant Energy, USPTO. March 2006. These include:
* Treatment and inspection
* Separating and sorting
* Medium of control
* Medium of communication
Many of these applications involve a source of radiant energy and a detector that responds to that radiation and provides a signal representing some characteristic of the radiation. Radiant energy detectors produce responses to incident radiant energy either as an increase or decrease in electric potential or current flow or some other perceivable change, such as exposure of photographic film.
One of the earliest wireless telephones to be based on radiant energy was invented by Nikola Tesla. The device used transmitters and receivers whose resonances were tuned to the same frequency, allowing communication between them. In 1916, he recounted an experiment he had done in 1896.Anderson, Leland I. (editor), Nikola Tesla On His Work With Alternating Currents and Their Application to Wireless Telegraphy, Telephony and Transmission of Power, 2002, . He recalled  that "Whenever I received the effects of a transmitter, one of the simplest ways [to detect the wireless transmissions] was to apply a magnetic field to currents generated in a conductor, and when I did so, the low frequency gave audible notes."

message: :Radiant energy, as defined by Tesla in his US patents, have nothing to do with any magnetic force. He carefully describes radiant energy to exclude magnetic forces.
:Tesla received two patents for this radiant energy device; U.S. Patent No. 685,957 - Apparatus for the Utilization of Radiant Energy and U.S. Patent No. 685,958 - Method of Utilizing Radiant Energy. Both these patents were filed on March 21, 1901 and granted on November 5, 1901. In these patents he explains:
:"The sun, as well as other sources of radiant energy throw off minute particles of matter positively electrified, which, impinging upon the upper plate, communicate continuously an electrical charge to the same. The opposite terminal of the condenser being connected to ground, which may be considered as a vast reservoir of negative electricity, a feeble current flows continuously into the condenser and inasmuch as the particles are ...charged to a very high potential, this charging of the condenser may continue, as I have actually observed, almost indefinitely, even to the point of rupturing the dielectric."  — Preceding unsigned comment added by 86.11.79.150 (talk) 14:20, 10 February 2012 (UTC)
