The full Goldstone rectenna video with voice-over by Powerbeaming Father Bill Brown. Shows working rectennas very clearlyhttps://youtu.be/9angvpwHOy8We have about 800 pounds of NASA DOE research on microwave power beaming studies and tests (SSI was chosen by NASA as the official archive and I know the weight because the collection was just shipped from storage in Princeton)Watch the video... and the ISU video is also on the SSI YouTube channel, that has Bill Brown and Peter Glaser. Then contact SSI.org if you are seeking more, we are digitizing the largest research collection now.Sent from my phone, please excuse typos.

There aren't any. Federal regulations regarding "acceptable" exposure to microwaves are not based on any scientific finding.The first is a list of over 100 studies done. You might question the validity ofthese studies, but that there are plenty of them is not in doubt.http://mercola.fileburst.com/PDF/123ReviewsNonthermalEffectsMicrowaveLowerFrequencyEMFs-MartinPall.pdfhttps://articles.mercola.com/sites/articles/archive/2010/05/18/microwave-hazards.aspxhttps://www.goodhealthinfo.net/radiation/health_efx_western.htm Can you be more detailed? If you're just arguing that a person can't literally string up chicken wire and convert microwaves to rectified DC, then sure, but that's a straw man. (This reminds me of the guy who cautioned me that getting useful elements out of regolith would never be as easy as just shining some concentrated sunlight on it. Well, yes, but who literally said that?) I don't think you can mean that a rectenna could never be designed which would let water through, or even the bigger fraction of the sunlight, given the vast difference in wavelengths between microwaves and visible light. Again, could you please share your findings?No I did *not* suggest literally chicken wire, that is why I said "somethinglike".Maybe I could have stated it better by saying: something like a mesh thatcaptures microwaves but lets all, or almost all, the light through. Of therectennas I've seen, none of them look anything like this. They are all mostly,if not almost completely, opaque solid surface.Here is a google image search for "rectenna array element":https://www.google.com/search?q=rectenna+array+element&source=lnms&tbm=isch&sa=XHere is a NASA study done on rectennas. See the picture of the rectenna on page 10:http://www.nss.org/settlement/ssp/library/1987-NASACR179558-RectennaTechnologyProgram.pdfHere's a page, at the bottom of which is (small) picture of a rectenna surface:http://www.spaceset.org/p.solar.mmHere's another rectenna page and picture, from the Japan space program:https://www.ijser.org/paper/Renewable-energy-Spaced-based-solar-Power-transmission.htmlhttps://www.ijser.org/paper/Renewable-energy-Spaced-based-solar-Power-transmission/Image_007.jpgHere's another picture of an actual rectenna:http://www.solarsat.org/Bill%20Brown%20tuning%20Rectenna.png"
