Before discoveries in the Rakis Finds of schematics and manuals of the leg endary device known as 'Leto's Cart, all that was known of it was that it used both wheels and ' suspensor bubbles" for transportation, was covered by a canopy which became clear or opaque a;, desired, and was unique Since the only model was destroyed when Leto died, all else remained a mystery We now know that Leto's cart was seven meters long three meters wide and with its canopy raised, two meters tall Because of Leto s special requirements, the cart was intended to be driven by a prone dnver judging from the control surfaces, it could be operated effectively only by Leto The body of the cart was a shallow shell with a low run which became a wide ramp for entry and exit Four wide wheels could be dropped from recesses in the corners of the shell, allowing this more efficient mode of travel when ground conditions permitted Built into the bottom of the shell was the main motive system two rows of six suspen sor bubbles each The Holtzman Effect fields created by miniaturized generators automati cally provided exactly enough lift to counter balance the weight of the cart and any 367 passengers Hie bubbles were shielded by refracted magnetic fields as a safeguard against lasgun attacks This protection long thought impossible, was kept secret Thus, many historians dismissed the suspensor bubbles of Leto's Cart as an utter fabrication, since eye-witnesses once reported that a lasgun beam struck the bottom of the cart Actually, the beams struck the magnetic fields surrounding the suspensor bubbles, and when the magnetic system overloaded, ft failsafe mechanism instantly vaporized the Holtzman generator in a puff of orange-yellow smoke The Emperor guided his cart through use of his atrophied legs Two control slots were located m the rear of the cart, and received Leto s legs when he lay m it The cart was directed by moving the legs from side to side for turns up or down for acceleration or deceleration, and in specific opposing direc tions to activate special functions such as switching from wheel to suspensor mode There were no provisions for maintenance access to the interior of die cart no doubt secunty precautions directed that its interior be solid-state A single panel in the interior of the shell near the driver's left side accepted a wafer battery every few months Tlie cart also contained; several capacitors which allowed it to be operated from stored power for a number of days, even without a battery m the power circuits A full-sized mockup of Leto's Cart is currently being built at the Discovery Museum on Rates, a working model is expected within two years Further references: ATREIDBS, LETO ir, DC, Alan Bartkc Survey ofIxkmTecktobgy, I0900-13SOO (finally Mosaic) LJCALLO, TAIAZOR.
