Rest In Peace, old friend, your work is finished.....

If you want ON or OFF the DIESEL ”KnOcK” LIST just FReepmail me.....

This is a fairly HIGH VOLUME ping list on some days.....

KnOcK!!!!!!!!!............

Although I welcome any provably functional concept along these lines, it seems like you’d have to have some screaming powerful motors on the drive axle; MUCH bigger than pictured. A 50 hp elec motor is already about the size of an axle differential. Somehow I doubt that 100 hp could pull a loaded semi truck. Maybe on some runs in Oz where there are fewer hills, but I don’t see it having enough power/torque.

A working prototype has not yet been built.

And you know why? Because it would not work! And to make it work they must make it uneconomical. How do I know? Because car and truck companies are in the business of making MONEY! If this made any sense to any consumer out there it would have been in production a long time ago.

People have been making electric cars since the 1830's and hybrids since 1901. It's not their time yet so... KnOcK it off already! ;-)

Talk is cheap. Prove the concept and I might buy it.

They are already working on a hydraulic motor hybrid with a pump, accumulator, hydraulic motor setup. It is used in UPS type delivery trucks. It has the advantage of unlimited torque, no batteries, and less maintenance and cost.

Just "Google" "hydraulic hybrid", for the latest pics.

A working prototype has not yet been built.

Which means I have some bridge stock for sale. This concept is not new. The military used what is called a no brake generator coupling with and electric motor powering a large mass flywheel to another generator back in the sixties.

Put a couple of these motors on the trailer axles and them mountains won’t be able to slow you down!

[USFRIENDINVICTORIA]

IMHO this is a great idea.

Volvo has developed a similar concept for heavy transport trucks.

The electric drive system is certainly not an issue. The largest trucks in the world use AC electric drive, with a monster diesel generator.

If this works, 25% fuel savings is 4-5 times what current OTR/Class 8 hybrid savings are being projected at. That is near the savings being seen for Medium Duty applications.

"We expect the conversion unit to pay for itself in the first year of use by way of the reduced fuel consumption."

And where does the free electricity come from?
