"   The Star Wheel: A human-powered, mobile Ferris wheel Time: Three months designing and three months welding at night after work Cost: Cost: $7000  Paul Cesewski describes his nearly 2000-pound, 22-foot-tall Star Wheel as a pedal-powered, interactive sculpture. Each of the three chairs located within the larger, 20-spoke wheel is equipped with a seatbelt and a bicycle drivetrain. &amp;quot;When you&amp;#039;re pedaling you&amp;#039;re pulling the chair around a fixed sprocket,&amp;quot; says the 43-year-old plumber. &amp;quot;And when you have three people pedaling and pulling themselves around, gravity takes everything forward.&amp;quot; Cesewski&amp;#039;s original bicycle Ferris wheel had only two seats and no outer wheel, meaning riders could go around in circles, but the machine itself was stationary. After receiving a grant from Burning Man in 2004, he decided to add the outer wheel and turn the contraption into what he calls a visceral social experience.\u00C2 While it&amp;#039;s a challenge to get the Star Wheel up to speed, some threesomes have actually endured a quarter-mile journey on it. Riders who decide to throw themselves into each pedal stroke might end up doing full flips in their chairs as the Star Wheel rolls along, which Cesewski swears is part of the fun. &amp;quot;I would love to take it through a city or ride it in a parade,&amp;quot; he tells PM. &amp;quot;But the biggest problem is the power lines.&amp;quot;      "^^<http://www.w3.org/2001/XMLSchema#string>
