Talk:Microwave power transmission

Untitled
Kyoto university has a group dealing with MPT, see the ( somewhat outdated ) overview of the ongoing reseaarch here: http://www.kurasc.kyoto-u.ac.jp/jusps/KA-1.pdf they have powered a flight experiment ( MILAX ) with a MPT and appear to be the most active current research group studying it.

I replaced the section on solar power satellites because it was out of sync with the main SPS article and was also very misleading in its content. For example, it used the inverse square law as the motivation behind SPSs, which is just wrong. A SPS can be nearer or further than the Earth from the sun depending on the time of day and even if it were always closer, it is not sufficiently closer to the sun than the Earth to make a difference (inverse square law is calculated using the relative distance from the light source...).

My stub should be fleshed out some, but only with info about how SPSs might use MPT, not general information about SPSs like it was before (that's what the SPS main article is for). --Flatline 13:51, 2005 May 11 (UTC)

Some explanation as to why this technology is not used would be helpful. Is it inefficient or something? Thanks, User:Dannyman

I an no expert in this matter, but I have a (rethorical) question: I understand that wireless devices, microwave ovens and maybe a lot of other devices use microwave. Would it be really possible to use microwave to send energy from a solar sattelite to Earth without interferring with home appliances and IT devices? And what about collision with particles when sending the microwaves?-Paul- 17:20, 10 January 2006 (UTC)

Since microwaves are just another section of the electromagnetic spectrum, this would be just like shining an extremely bright flashlight on to a solar panel a ways away. While there is the potential to interfear with comunication devices, if they happened to be on the same frequency, this would only be an issue if you were standing in the microwave beam, just as the only time you could be blinded by the flash light would be when you were between it and the solar panel. Since this would also sap the power, the recttenna area would closed off and the the beaming device would probably turn off automaticly if it strayed from the rectenna. cc 24.137.78.34 22:23, 24 February 2006 (UTC)

They'd better not build one near an airport. I know from experience. --NEMT 22:55, 27 May 2007 (UTC)

Copyvio false alarm
Looks like the text of the purported copyright violation has been in this article since Jan 10 2004 (and uncharacteristically stable since then!). Since this report says it's published July 2008, I suggest it's an uncredited quotation of Wikipedia, not a copyright violation here. --Wtshymanski (talk) 15:23, 12 February 2009 (UTC)
 * I concur and note that no archives exist to support an earlier publication of that summary. Lacking an earlier source that than tagged, here, evidence suggests the infringement is reversed. --Moonriddengirl (talk) 20:23, 12 February 2009 (UTC)

Broken link
My thanks to you who have produced this "low priority" page. 2 things: the link (6) seems to be broken (sigh) " POINT-TO-POINT WIRELESS POWER TRANSPORTATION IN REUNION ISLAND 48th International Astronautical Congress, Turin, Italy, 6-10 October 1997 - IAF-97-R.4.08 J. D. Lan Sun Luk, A. Celeste, P. Romanacce, L. Chane Kuang Sang, J. C. Gatina - University of La Réunion - Faculty of Science and Technology."

Briefly, I'm a generalist. I have reason to believe this topic will have significant value in the not too distant future; especially regarding PTP. There are many valuable applications of modest digital technology (intelligently operating valves, flipping low power switches which operate small motors or acuators..) whose process has very modest power requirements. But it just ain't worth stringin' the wire right now... Thanks again! rB —Preceding unsigned comment added by 206.174.9.242 (talk • contribs)
