Project METI@home: Messages to ETI from home

Alexander L. Zaitsev, IRE RAS, (alzaitsev@ms.ire.rssi.ru)

SETI@home consists of a receiving Arecibo antenna, a professional team (PT), and a two-way Internet connection between the PT and an army of S@h users, who load from the S@h server special software for digital signal processing. Project METI@home should solve the inverse problem, and therefore it must have an inverse structure, which is derived from S@h by replacing receiving and analysis of space radiation with synthesis and transmission of radio signals; in other words, by transitioning from a science of searching for alien Messages to an art of composing our own interstellar Messages. Thereby, METI@home will consist of several originators, which may load via Internet from a M@h server special software for the creation of analog and digital messages. The PT (Art Jury) makes an examination and selects the most impressive of these messages for their subsequent addressee transmission from Evpatoria or similar planetary radar to selected target stars. Demo versions of special software for composition of four-color digital Messages is available at http://www.seti.housenet.org/test/ and http://www.seti.housenet.org/apps/
