Antigravity lifters

Article in the August issue of Wired Magazine on antigravity devices called lifter which have no prompt region and require no onboard fuel provision . They almost look like the genuine mint . Sounds crazy , but patently they do work . The only snag is that it ’s not antigravity that makes them vanish :

What makes lifters flee ? The simple-minded answer come from antigravity debunkers . When I call university physicists to ask how these things work , they bark with laugh at the idea that it ’s antigravity . The propulsive military force , they say , has a simpler account : ion wind . When the current enrol the wires ringing the top of the lifter , negatron race off to ionize the beleaguer melodic line . The ion are attracted to the foil skirt and race down , smack into indifferent speck and generating a downwardly - moving breeze . At one decimal point , I take my lifter to Rainer Weiss , a overactive , white-haired - hirsute gravity expert at MIT . He ’s working on the innovative LIGO project to detect gravitational wave – when he ’s not carry on with journalists who plonk tin foil UFOs down on his desk . He shakes his head and sighs . “ There is nothing cryptical about this at all , ” he says . He scribbles furiously across two sheet of paper , calculating the current flowing through the machine , the telephone number of ions it would create , and their total potential kinetic drive . It ’s about 7 millinewtons , he concludes , and scoop up my lifter . “ Do you know how much this weighs ? permit ’s take a guess – it ’s a couple of gramme . ” That ’s probably just idle enough to get it airborne . As far as he ’s bear on , my lifter is nothing more than a hovercraft . Case close .
