EPA Develops Hydraulic Hybrid System
The Environmental Protection Agency has developed a new fuel saving
technology called hydraulic hybrid technology. This system stores
energy created while braking in pressurized hydraulic fluid. This is
the same sort of fluid used in power steering and in brake lines.
Gasoline-electric hybrids like the Toyota Prius store energy from
braking as electricity in batteries to power a supplementary electric
motor. The EPA's hydraulic hybrid system stores the energy from braking
by compressing hydraulic fluid. The hydraulic pressure is then released
to power gears used to help turn the vehicle's wheels. Both forms of
hybrids can also store energy while the car is driving.
