MacGyver was an American adventure television series about secret agent Angus MacGyver. It ran from 1985 to 1992. MacGyver's main asset is his practical application of scientific knowledge and inventive use of common items – along with his ever-present Swiss Army knife and duct tape, since than often called “MacGyver tape”. With this he always managed to escape capture, avert disaster, or defeat the antagonists. MacGyver now is also used as a verb meaning to fix, repair, rig, solve, build, invent, or otherwise save the day.

The German Institute for Fluid Power Drives and controls (IFAS) at RWTH Aachen University has built a simulation model of the Hydrid. In this model, the efficiencies of the hydrostatic components are derived from measurements on existing floating cup machines. The cycle analysis show that the hydraulic components themselves create more losses than the mechanical transmission. But these losses are more than compensated by the energy which is recuperated during braking. Including recuperated brake energy, the total efficiency of the Hydrid is in the end somewhat better than the estimated efficiency of an all-wheel drive mechanical transmission. |
