Hybrids got a lot of press when gas was $4 a gallon, but now that it is below $2, does anybody care? Well, Eaton does.
Eaton has been in the power, hydraulics, and automotive business for quite some time, quietly developing new technologies used in most cars, trucks, and heavy trucks today. Cheap? No. 100% Free. Trade stocks for free on Zecco.com. The Free Trading Community. www.zecco.com
As I have written previously in "Hybrid Hummer Hums," Eaton was a main supplier in the hydraulic units for that vehicle. In this article, I will discuss two Eaton implementation of hybrid technologies.
Parallel Hybrid System
The picture above graphically displays Eaton's Hydraulic Launch Assist system, a heavy vehicle (garbage truck) with a standard engine, and hydraulic system is supplemental power. It is designed to capture energy through regenerative braking, store it in hydraulic fluid, and then use it to "launch" the vehicle from a stop.
From Eaton's web site, "During acceleration, fluid in the high-pressure accumulator is metered out to drive the pump/motor as a motor. The system propels the vehicle by transmitting torque to the driveshaft." This system is able to work in either Economy or Performance mode. The difference being that engine doesn't perform acceleration until after the hydraulic system is spent in Economy mode, while in Performance mode, both the engine and hydraulic system work together. In either case, Eaton predicts a 20-30% fuel efficiency increase.
Series Hybrid System
A series hybrid varies from a parallel system in that, "... conventional transmission and driveline are replaced by the hybrid hydraulic powertrain and energy is transferred from the engine to the drive wheels through fluid power."
The series hybrid allows the engine, mated to a continuously variable transmission (CVT) to operate at optimum efficiency, while "energy is transferred from the engine to the drive wheels through fluid power." This system also uses regenerative braking and managed engine cut-off to show fuel efficiency improvements of 50-70%. Would you feel better if you had more energy? Try FRS® Healthy Energy™ Free*!

Although these systems are not in full production, they are the leading edge in hybrid technology for heavy vehicles. Think about these hybrid systems when you see a city bus or garbage truck accelerate from a stop. Imagine seeing that same bus accelerate, but without that black cloud. That is progress.
I hope nobody reads your ramblings, mate. You clearly ignore the horrors and suffering that Chernobyl caused and still continues to cause to Eastern Europe. Nuclear energy is not safe, period. Anyone who says so is ignoring the number of accidents around the world that get reported 2-years after they happened -- or never if they can conceal it (Russia?).
We -- Germans -- simply do not trust the people working in nuclear power plants. The technology may be alright, but the human beings inside are no computers, we all make mistakes. Chernobyl was no technical issue, but a series of very unlikely human errors. As long as we are in control, nuclear power is not safe. OTOH I wouldn't even think about giving a computer total control over such a thing.
And please, stop bragging about your superior common sense, when it sounds more like some down-home-hokum. You clearly have little facts at your hands as you continue to accuse every other person on this planet to have none.
Look at some pictures of the people dying in Chernobyl and read about their stories and then remember that it was a human error that can and will happen again. Maybe this could teach you some compassion.
And while we're at it, just buy a bike and use it instead of a car and choose home appliances by their energy usage -- the German build ones are pretty good at this, maybe then you can understand that our environment is pretty dear to us.
