For instance, why do elevators have to have a shaft? They could as well spiral around the building. They only need energy to go up and could be lifted by some kind of crank like rollercoasters and go down by gravity alone, with air dampening or using Lenz current (or some other method) to slow it down. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#4F6228'>Elevator companies lack imagination. </span><span style='font-size:10.0pt;font-family:Wingdings;color:#4F6228'>J</span><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#4F6228'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>That is a cool idea Henrique. We could have concentric helical coil tracks that elevators would go up driven by linear magnetic actuation, like a scaled up linear stepper motor. Each loop around the perimeter of the building could raise the proles two floors, or more for that matter, then we could arrange cars going in the opposite direction continuously. Might be too slow perhaps. But it would look cool, especially if it is on the outside of the building.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>spike<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div style='border:none;border-left:solid blue 1.5pt;padding:0in 0in 0in 4.0pt'><div><div><p class=MsoNormal><span lang=PT-BR><o:p> </o:p></span></p></div></div></div></div></body></html>
