Show sal aless S sailing al i 0 n g ship p for future new invention relies on air for power berlin the mulling bailing vessel of the future will be without soils sails if tile new invention of dr anton flettner Flett ncr known knon us its the flettner rotor proves to be all that Is 18 claimed for it instead of wooden finsta rigging anti and sails the lie now new equipment will consist only of metal masty reset resembling abling smokestacks smoke stacks revolved on their a axis ais by it a motor experiments with a ton hull bull fitted its as above set forth have shown that with one fifth of tile the slight of the hie custo customary wary tin and 1 I na mills lis the rotor phlp can develop I 1 times the wind power of tile ordinary sit I 1 vessel the file rotor ship faill does not hot have to bo be hauled out of the harbor by it tug it starts tile minute fit lie cylinders driven by a small diesel motor begin to rotate tills this motor can call be handled by one person on the bridge anti and all the crew formerly necessary for hailing can call bo be dispensed with irom from tin an economic stand standpoint fill tile lie inventor that from froia 0 to SO 80 per cut cent can cai be sael on fuel it if the rotor lotar device Is installed the rg ani erl can line lias has ordered the lie construction of a 10 OW ton freighter reig lito r which Is to sill sail with rotors instead of stills satis and the whole ship ping world orld Is inquiring into the adaptability of the invention to pass passenger the principle on which the nev still ship operates lias has been explained by herr 11 doctor Flett ners right hand man as aa follows air course studied supposing a current of nir air strikes a smooth cylinder cv under buch as it a smokestack or the cylinder of our rotor what will vi happen the air will pass to the right and to the left of tile cylinder about evenly now suppose one half of the cylinder were covered oi ered with some rough surface such its as sandpaper what would happen ohp nil I 1 current following the lines of least resistance would pass on off toward the smooth side hide und and only very little of it toward the roughened side in other words the lie air current will I 1 go where here there Is least I 1 to 0 it suppose next that we begin I 1 to 0 turn the smooth cylinder by so some me mechanical chal ch lical HUMPS much lucli us its an electric motor As it revolves onside one of it the appearing til side its as ou look at it from thi front will be ino vint it in the same direction in which the air current la id moving while the lie other side will run counter to the air cur adit naturally alk he air following follo ing the lines of least regis tunce will off toward the side aldr s where tile cylinder turns avith the wind it follows that it if the cylinder I 1 turned faster than thu the velocity of till lir yand gilld there Is absolutely no friction on the cne side for the alie air and the aholo current will he be deflected to that dial i tin nf side with such vehemence tind with such crowding together it if em rent that hut suction ensues on the hie side revolving with the wind vind while on nn tile the side hide coming up tit against the wind a pressure against tin the 0 cylinder under 11 is produced this combination of suction tin on one tide of tit lie cylinder 0 under anti of pressure tire 0 on n the other forces tin ill forward end and balls can be dispensed will steel supports cylinders tile revolving or rotating rg are mounted on strong bagts of steel in tile ase tit if tile lip 1 I 1 till ship tile the the 1110

cylinders nt tile rate of f about revola tlona a minute in the case casa of a sailing vessel therefore 08 98 per cent of the power Is produced by tile lie wind acting upon tile cylinders while only 2 per cent la Is contributed contribute by the aman motor that ono one person can attend to tho the rotor still ship can be made to reverse its direction by merely reversing hg tho the motor to turn tile bout boat about abou 1 one olle cylinder Is ninde to turn in one direction d 1 and the other lit in the opposite just us its in rowing one turns by pulling at one our oar antl pushing the other the fact that tile the changes or of speed or the reversing of the inetor can bo be done instantaneously makes it possible for the lie new flew ship to ride a storm sto rm a easily its as it moves in clear lier the Flett ncr I people ople look upon tit alio rotor still ship as a mero beginning begin ng ilion abony 4 the rond of gaining energy from the lie air some day the wind may be giving US
