CLEVELAND, Ohio -- After a year in service, Parker Hannifin Corp. is calling its fleet of demonstration hydraulic hybrid garbage trucks in Florida a success. 

Used in Miami and other cities, the trucks have used 43 percent less diesel fuel than traditional trucks and have had almost no breakdowns.

"Having seen the results in these pioneering South Florida communities, many more municipalities and fleet operators have shown interest in purchasing vehicles featuring our RunWise technology," Parker hydraulics group president Jeff Cullman said in a written statement.

The Parker trucks are hydraulic hybrids. Gasoline-electric hybrids such as the Toyota Prius store energy in a large battery and use that electricity to power the vehicle at times, reducing the use of gasoline. 

The Parker system captures energy normally lost when the vehicles brake and stores that in compressed hydraulic fluid. When the driver hits the accelerator pedal, the system releases the compressed fluid, launching the vehicle from its stopped position. The diesel engine then moves the trucks at higher speeds. 

"The hybrid is faster, more dependable, experiences less noise in the cab and has not encountered any problems," Scotty Rodgers, an Miami truck operator, said in a written statement. "The truck moves very smoothly from stop to stop allowing me to get through my route more quickly."

In addition to hitting its fuel economy targets, the test trucks were in service 99 percent of the time during their first year, a reliability statistic that Parker plans to promote as it begins selling the hybrid systems nationwide.

At a typical movie premiere, stars dressed in thousand-dollar ensembles step out of limos and onto a red carpet. But at the Austin premiere of Associate Professor Andrew Garrison’s “Trash Dance,” stars dressed in neon city sanitation uniforms roll up in garbage trucks.

After all, that was Garrison’s goal in directing, producing and recording “Trash Dance.”

The world premiere takes place during the South by Southwest® Film Conference and Festival (SXSW) at 1:30 p.m. on Saturday, March 10, at the Paramount Theatre, 713 Congress Ave. After the premiere, the director, producer and cinematographer will host a premiere party and Radio-Television-Filmalumni gathering from 6-8 p.m. at Progress Coffee, 500 San Marcos St.

In “Trash Dance,” choreographer Allison Orr works with Austin sanitation workers and garbage trucks to create a dance performance. The film follows the daily lives of the employees and the rehearsal process that led to a final performance that features 16 trucks, 24 dancers, a piano, violin and cello.

Associate Professor and “Trash Dance” director Andrew Garrison is an award-winning independent filmmaker with experience in both documentary and dramatic film production.Garrison hopes viewers will be entertained and moved by the film.

“It speaks about dignity of work and the way that the work we do can be a conscious act of beauty,” Garrison said. “Art does not end at the edge of a stage or a museum door. The film also introduces you to the people who do this work every day. You know public employees are sometimes attacked as living off taxpayers’ money. You get to meet these people and see the effort they put into the job and their personal goals. I hope that makes a lasting impression.”

After the world premieres, Garrison will look into international television broadcast opportunities for “Trash Dance.”

Including “Trash Dance,” University of Texas at Austin faculty members, staffers and students are screening about 20 films at SXSW.http://www.utexas.edu/know/2012/03/09/trash_dance_garrison/
