* California - Turbine generator could solve range anxiety in electric-powered garbage trucks
-- “Maintenance nightmare”: That’s how Lou Ratto, chief operating officer of a waste and recycling company in Sonoma County, Calif., describes the challenge of keeping his garbage trucks compliant with the state’s air quality standards... In August the Ratto Group will receive a garbage truck with a battery-powered electric motor, and a turbine generator that will extend the truck’s driving range. Traditional garbage trucks get awful gas mileage, but putting electric motors in them has proved challenging given concerns over the range of the batteries... Ratto has signed a contract with Wrightspeed to outfit 17 trucks of his trucks with its electric powertrains, which include its new turbine generator, called the Fulcrum. The turbine can run on fuels ranging from diesel to natural gas to propane and kerosene. Ratto will use diesel... The turbine charges the battery, which then powers the wheels. This is a crucial distinction, as using turbines in vehicles has traditionally been unappealing because turbines are so inefficient at low speeds. Since the turbine is charging the battery and not powering the wheels at idle, there’s no problem... FedEx has pilot-tested the technology and placed 25 orders for its fleet...
