The hydraulic hybrid-drive system the EPA may or may not have stolen appropriated from a guy named Car Man (or thereabouts) is ready for more real-world tests, the Wall Street Journal reports. The govs that be are planning to roll out their hydraulic system in a Peterbilt garbage truck, to be marketed by a Cleveland company starting next year. The truck uses a hybrid combination of diesel engine and hydraulic pump that saves braking energy as pressure, which it releases as force. UPS has been testing a similar system on two of its gajillion trucks since June.
