      XPost: sci.physics, sci.space.policy, sci.electronics.design       From: rgregoryclark@gmSPAMBLOACKail.com              Nanotechnology makes possible an "ion drive" for air vehicles analogous to       the famous ion drive of NASA's deep space probes:              Carbon nanotubes for "Ionic Wind" Craft or "Ionocraft".       Clark R*       Department of Mathematics, Widener University, USA       Review Article       Volume 1 Issue 2 / Received Date: September 26, 2016 / Published Date:       October 20, 2016       Abstract       Peter Thiel of the Founders Fund once famously said, "We wanted flying cars,       and we got 140 characters."But nanotechnology now does make possible the       long desired flying cars. It's a different propulsion method though than       propellers or jets however. It's propulsion by electric fields known as       electrohydrodynamic propulsion (EHD). It works by ionizing air then using       electric fields to propel the charged air molecules rearward, thus producing       thrust. It's quite analogous to the famous space ion drive of NASA. EHD has       been known at least since the sixties. Its problem is, as with ion drive,       the thrust is so low. So far the EHD craft have not been able to lift both       themselves and their power supplies. The ones made so far leave the power       supply on the ground and connect to the craft through power cables. But the       equations of EHD suggest the thrust for the power required gets larger for       thinner ionizing wires. In fact if the wires are at the nanoscale then this       important thrust-to-power ratio can be a hundred times higher than for the       craft constructed so far. This would be enough to lift the craft and the       power supply. This research is to prove what the mathematics suggests. Note       that if it works then all propeller and rotor driven craft become obsolete.       Also, intermediate range automobile travel would be taken over by the EHD       craft, so a large proportion of carbon-emissions would be eliminated,       replaced by this zero-emission travel method. In regards to space       propulsion, since EHD is so similar to ion drive, using components at the       nanoscale may also work to improve the thrust of ion drive. This would be       important to shortening the flight times of spacecraft using such drives.       This is important not just for robotic spacecraft but also satellites that       use such ion drives to reach their final GEO destinations. As it is now, the       ion drives used have such low thrust it takes months for such satellites to       reach GEO, resulting in millions of dollars of lost revenue to the satellite       companies. Being able to increase the thrust of these drives would reduce       the flight time, and therefore reduce this lost revenue.       Keywords: Electrohydrodynamic propulsion; Carbon nanotubes; Nanowires; Ionic       wind; Ionocraft; Plasma drive       https://medwinpublishers.com/NNOA/volume.php?volumeId=23&issueId=63              Bob Clark              ----------------------------------------------------------------       -----------------------------------------------------------------       Finally, nanotechnology can now fulfill its potential to revolutionize       21st-century technology, from the space elevator, to private, orbital       launchers, to 'flying cars'.       This crowdfunding campaign is to prove it:              Nanotech: from air to space.       https://www.indiegogo.com/projects/nanotech-from-air-to-space/x/13319568/       ----------------------------------------------------------------       -----------------------------------------------------------------              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
