The Autocar E3 refuse truck has an energy recov- ery system developed by Parker Hannifin LLC that is expected to reduce fuel consumption by 50%. Pressurized fluid flows from carbon fiber-reinforced accumulator tanks to two hydro- static motors that propel the vehicle forward. The truck recharges the accumulators when it brakes. If the fuel cost for a regular refuse truck is $800 per month, how much can a private waste hauling company afford to spend on the recovery system if it wants to recover its investment in 3 years at an interest rate of 12% per year?
