... Look up LOFAR or the SKA (Square Kilometer Array) for a fairly well funded scheme. LOFAR. http://en.wikipedia.org/wiki/LOFAR LOFAR like my proposal is to use many separate dipoles to detect long wavelength radio waves. However, it is to have only 10,000 dipoles whereas mine at the end will have ca. 1 billion dipoles. The progenitors of the LOFAR project have argued in papers that it could be used for the SETI search. However, this article by well known SETI search scientist Seth Shostak argues LOFAR will be too weak to detect Earth type radio transmissions at a distance of say 55 light- years by a factor of 1 million: Listening for ET’s Television. November 9, 2006 by Seth Shostak, Senior Astronomer http://www.seti.org/Page.aspx?pid=917 Then since my proposal will be about 100,000 times more sensitive than LOFAR, it could detect Earth-like radio transmissions to about 1/3 the distance of 55 lightyears, or to about 18 lightyears way. There are several star systems in that range. The Shostak article notes you could get several hundred times better sensitivity by listening to certain stars over months or years. Then my proposal could detect such transmissions out to even 55 lightyears and further. Bob Clark |
