This document introduces Richard Branson to a new technology called Regenerative Acceleration Generator developed by Potential +/- Difference Inc. that can increase energy efficiency in trains by 50-75% by reversing the magnetic field in regenerative braking systems to provide acceleration instead of deceleration when returning energy to the grid. Independent tests found the technology can increase electrical output by over 200% and triple efficiency. The company seeks to partner with Virgin to integrate the technology into trains to reduce energy use and carbon emissions.

Regenerative Acceleration Generator Technology
Introduction to Richard Branson
Hello Richard,
Please allow me to introduce you to a new technology innovation that will help you achieve and even
exceed many of your energy efficiency/CO2 reduction targets. This innovation can be immediately
integrated into your trains and reduce energy consumption by 50 – 75%.
This new innovation is called Regenerative Acceleration and it is the exact flip side of regenerative braking
which is already employed in your trains which I was happy to read about last night on page 196 of your
book, “SCREW IT LET”S DO IT.”
Regenerative braking, as the name implies is a decelerating effect that the electric motors in your trains
create when they are operating as generators and sending power back to the trains batteries or grid. The
braking forces are caused by a magnetic field that is created inside the generator which produces a
counter-electromotive torque on the generator driveshaft. This counter-torque works against the direction
of rotation of the train’s wheels which are originally rotating the generator and the train decelerates as a
result. Our company discovered in 2007 - completely by accident that this internal magnetic field torque
direction can actually be reversed!
We had the original discovery validated at MIT, Ontario Hydro and the University of Ottawa although not
one PhD had any clue as to what was causing our generator to accelerate when delivering power to a load
when all conventional scientific wisdom said it ought to decelerate. The University of Ottawa then kindly
and bravely provided us with lab space from 2008 – 2010 against massive internal resistance and
university politics so that we could develop the backing theory and refine the technology, which we are
now patenting and commercializing worldwide.
The innovation developed by our company is an electric generator which reverses the generator’s induced
torque direction and produces a complementary-electromotive torque instead of a counter-electromotive
torque. The result is an electric generator which has the ability to send power back to the grid while
creating a torque which will not decelerate your trains but will actually help accelerate them instead
(again, while simultaneously sending power back to the grid). In addition, the complementary torque
created by our generator adds to the train’s original motor torque and reduces the energy consumption
accordingly.
Third party independent tests carried out by a Canadian National Research Council of Canada scientist at
the University of Ottawa have shown that the input energy reduction can be as high as 60% while the
regenerative energy returned to the grid exceeds 800% over a conventional generator under identical
operating conditions. https://www.box.com/files#/files/0/f/0/1/f_5554651590
In regenerative braking mode the conventional regenerative braking generator will eventually decelerate
your trains down to a dead stop while the regenerative output will eventually fall to nil. The regenerative
acceleration generator on the other hand will help accelerate your trains up to their full speed while the
regenerative output delivered to the grid continues to increase.

Regenerative Acceleration Generator Technology
Introduction to Richard Branson
The regenerative braking system currently on your trains can only be employed under deceleration or
braking but the regenerative acceleration generator can be employed during virtually 100% of the train’s
operation, during acceleration, coasting, deceleration and braking – with or without a regenerative braking
option.
If a flywheel energy storage system (KERS) is employed the regenerative acceleration generator can
continue to send power back to the grid long after the train has been stopped – exceeding the usability
duration of the innovation to well over 100%. The only thing that will cause the generator to decelerate
while sending power to the grid while operating in flywheel mode is the generator’s bearing friction but
even this can be virtually eliminated with magnetic bearings. PDi has developed a passive conical
magnetic bearing system with this in mind which is currently now being licensed by NASA.
It is even conceivable that a regenerative acceleration flywheel system in your trains will still be sending
power back to the grid when the engineers return in the morning after the trains have been parked
overnight. In a conventional regenerative braking generator the more regenerative power delivered the
greater the breaking/decelerative effect and the higher the rate of deceleration. Whereas in the
regenerative acceleration generator the exact opposite is true, so the more power returned to the grid the
more acceleration the generator creates and slower the rate of deceleration in flywheel mode.
This innovation can be employed not only in trains, planes and automobiles but wind turbines, nuclear
power generators, hydroelectric generators, motors and so on. Virtually any electric generator or motor on
the planet and in outer space.
My wife Kim and I stopped by Virgin Green Funds New York office on our way back from the University of
Virginia ROMAC Lab (where the passive magnetic bearing design was first introduced for flywheel energy
storage systems) way back in 2006 but we didn’t get a chance to speak to anyone so I hope this letter
and the one below finds its way to you in 2013.
Love your book BTW – should finish it today!
Thanks and kind regards

Now there is a solution to this madness… imagine for a moment
if you could take the waste exhaust from your car's engine and
process it in such a way that it could be reconverted back into
gasoline and returned to your gas tank as you drove down the
road?
Now, imagine if you could use this process to double or even
triple the range of your car and all fossil fuel powered vehicles in
the entire world – while simultaneously cutting the green house
gas emissions in half?
Can you imagine the value an
innovation like this would have
on the world energy stage –
or on the environment?
Now of course this can't be done with a gas powered engine but
it can and is being done right now with electric vehicles motors
by an Ottawa based company called Potential Difference Inc. (PDi)
and the innovation doesn't just work with electric vehicle
generators but all types of electric generators.
Independent testing provided by a National Research Council
of Canada scientist showed over 200% energy output gain
with 40% less energy input – effectively tripling the efficiency
of ANY electricity generating method.
At their satellite lab at the University of Ottawa from 2008 - 2010 PDi has developed a method of
actually reconverting an electric vehicle motor's (electro-magnetic) waste into usable electric
energy and using this to recharge the EV's batteries. This innovation now allows all electric
vehicles to partially recharge themselves as they drive. Electric vehicle (2X) range doubling has
already been achieved with (3X) triple range increases expected in the 2013.
