Larry's Geo Tracker with H.O.P.E. genset gets over 2x stock mileage
This week, I witnessed two tests of Lawrence Sadler's High Output Propulsion
Electric system, producing over 50 mpg on the road, even with a clutch that was
going out; and over 60 mpg on jack stands (converted to road equivalent).
Pure Energy Systems News
I'm on my way back from Florida, USA, having visiting Lawrence
(Larry) Sadler of LRS Innovations . He's doing some amazing work. I gave a
brief overview of his various projects in our PESWiki feature page about him,
which many of you have probably already seen. Since we sometimes update PESWiki
pages to keep them current, as a historic archive, I'm going to post below
what I wrote on December 10 at PESWiki.
If you've not already reviewed that, I suggest you do so now, so you can
appreciate the stature of this man as a credible inventor with a significant
portfolio, including his involvement 40 years ago in miniaturizing integrated
circuits. It's also fun to see him tinkering with more exotic free energy
technologies including a magnipulse motor (all-magnet motor) and a Van de Graaff
electrostatic energy harvesting system. Probably his most impressive technology
is his energy storage technology, which isn't yet integrated into his HOPE
vehicle, and would boost it's mileage probably by another 10-15 points from the
weight reduction and performance, not to mention its potential indefinite
lifetime, compared to batteries, which usually have to be replaced every 10-20
This present page is to highlight the H.O.P.E. (High Output Propulsion Electric)
vehicle test we did on December 11.
About four years ago, Larry converted a 1996 Geo Tracker, into an electric
vehicle. He removed the stock engine, replaced it with a 110 horsepower DC
electric motor connected to the drive train. He the used at 13-horsepower diesel
engine to turn a super-efficient (93% efficient) alternator to produce
electricity to charge the battery bank on-board, to keep them topped off, so on
average, when you reach the end of your trip in the Geo, the batteries are fully
One of the primary components that he came up with in this system is his
patent-awarded battery management system, which allows you to charge the
batteries in series at the same time you discharge them in parallel. His
management system also prevents the middle battery of a battery pack from being
overworked between charging and discharging, preventing its overheating and
The system could also be used to plug into your home to power your home.
2011 Dynamometer Test
Larry gave me a copy of the dynamometer data
he notated on November 15,
2011 running his Geo with this set-up. They ran it for 20 miles on the
dynamometer between 55 and 65 mph, to hold the output load close to 50 amps.
Prior to the test, he took the Geo to a vehicle weighing station to get its
weight: 2620 lbs. The dynamometer was set for 3,000 lbs, to simulate two
passengers, and the make, model, and year of the vehicle were entered into the
computer for it to then simulate the rolling and wind resistance as if it were
driving down the road. The fuel at the start was weighed at 48 oz, and at the
end at 34 oz, which comes to 24 oz of fuel used. The results came to 93.7 mpg.
I've posted (unlisted because it won't really be appreciated without this
context) a video Larry took of his
dashboard meters during the November 15, 2011 dyno test. The output amp meter on
the upper left is essentially unreadable with the glare. The speedometer shows
the wheels spinning between 55 and 60 mph during this 42-second sampling.
More recently, Larry switched the diesel engine with a gasoline engine, which
isn't as efficient. So the results we got were not as impressive. I keep meaning
to ask him why he switched, and why he doesn't switch back. It might be a
function of the size.
On December 10, Larry took me out for a ride in the Geo. It was running okay
until we started smelling clutch; at which point it became difficult to shift.
He pointed out that this is a mechanical problem due to the age of the vehicle,
and had nothing to do his technology -- just a little Murphy's law in play. On
that short run, with a slipping clutch, we measured around 50 mpg, as
gauged by the number of miles driven and the amount of fuel required to restore
the level of fuel in the gasoline tank.
So what we did for the December 11 test was to put the Geo up on jacks, in fifth
gear, which didn't slip, with the objective of spinning the tires fast enough to
pull a 30 Amp load to the drive train motor. This would then be compared to the
dynamometer test in November 2011, which pulled 50 Amps running around the same
speed. However, that plan didn't quite hold true, because on December 11, the
speed required to pull 30 amps was 75 mph, whereas the Nov. 2011 dynamometer
test ran at an average of around 60 mph (between 55 and 65, the notes said). We
don't have that data to see how much it was varying, or how constant or not it
In the first part of the December 11 test, we were using one brick to hold the
accelerator pedal in place, but the vibrations of the vehicle were causing the
brick to move, so it would gradually drop down to maybe 28 amps, at which point
we would readjust the pedal.
In the last half of the test, we used two bricks, which was sufficient to hold
the accelerator pedal steady, keeping the amps at 30, +/- 0.25.
So any tabulation we get to arrive at an estimate mileage for the test we ran on
December will have a fairly significant margin of error. It's not just a matter
of multiplying the miles driven by 3/5 (30/50 amps); nor will it be a matter of
multiplying by 60/75 to adjust for the different in speed. It seems to me that
there is enough difference between these two sets of parameters that we can only
get a rough estimate of mileage.
Given these considerations, here are the numbers we got:
- (Estimate of) Load amperage during first half ~28.5 amp +/- 0.5
- Load amperage during last half ~30 amp +/- 0.25
- Tire speed during first half: ~65 mph +/- 5
- Tire speed during second half: ~75 mph +/- 2
- Fuel used 2.00 L (minus 8 oz found later in the line and carburetor) (+/-
- Distance traveled (on odometer) 59.8 miles
|According to Google:
(8 oz = 0.24 L)
(2 L - 0.24 = 1.76 L = 0.46 gal)
59.8 miles / 0.46 gal = 130 miles/gal
x 3/5 = 78 miles/gal
x 60/75 = 62.4 miles/gal (probably +/- 5)
[I'm not sure about the applicability/accuracy of that last step]
The reality check is that the data we got on December 10 was 50 mpg, with a
slipping clutch, so that a portion of the output amperage was going to that
Despite the lack of precision in our protocol and measurements, I'm thinking it
is safe to say that Larry's modification of the Geo Tracker easily improves the
mileage by well over two-fold from the stock highway mileage, which is
around 25 mpg.
Here's a video with some photos from
the test Thursday:

I'm here with Lawrence (Larry) Richard Sadler, a gifted inventor in
He has four patents, with a fifth pending. Two of them are phenomenal
energy-related inventions. They're not free energy, but are great
transitional technologies and tools for when we finally do get free energy
technologies to power the future. He's also working on two free energy
prototypes: a magnepulse motor and a Van de Graaff electrostatic energy
One of his patented energy technologies is a H.O.P.E. (High Output
Propulsion Electric) vehicle. It's an electric car with on-board generator
(genset), so rather than burning fuel in an ICE connected to a drive
train, you run a low, 13-HP engine to turn a super-efficient alternator
(93% efficient) to produce electricity to power and balance the batteries
that power the 110 HP DC electric motor connected to the drive train.
He's able to get 93.7 mpg in his Geo Tracker that usually gets just 30
mpg -- a three-fold increase in efficiency. He's put ~3000 miles in road
and dynamometer testing on this Geo prototype so far.
When you're done driving, the battery is not depleted. The 10 kW
generating system keeps the batteries topped off. What's really cool about
this is that now your car can power your house. You drive home, and plug
your house through an inverter into your car as a back-up generator, able
to keep your essential functions operating.
He says with optimization, the efficiency could be even greater than
that, adding regenerative braking, and aerodynamic vehicle design, and
light-weight chassis and body. I'm going to be suggesting that he consider
adding an HHO
system as well, which could improve the efficiency another 10-15
The other energy-related invention is a unique energy storage system. His
prototype stores well over 100 Farads, and at the end of 6 months will
still hold 95% of that charge -- unheard of for any capacitor-related
storage. Compare that to a classical capacitor, where a 5 Farad system
might be the size of a typical car battery. But like a capacitor, it can
charge 10,000 times faster than a battery. His prototype pegged a 10,000
amp meter at 32 volts (at least 1/3 a megawatt) for a pulsed output, able
to repeat after just 10 seconds, compared to the 45 minutes required for
similar existing technologies. It's good for billions of cycles --
essentially unlimited. And the prototype weighs around 100 lbs. Imagine
that for your regenerative braking or solar/wind battery array. Its cost
is expected to be competitive as well.
Outside of energy technologies, Larry has developed a natural food
ethylene converter that he calls S.O.L.E. (Super Organic Life Extender).
It is said to extend the life of foods, organic produce, or flowers by
three-fold, whether in the fridge, grocery store, or shipping container.
- S.O.L.E. Technologies, LLC is a company that specializes in Green
Technology products. The Super Organic Life Extender known as the
S.O.L.E. system is a revolutionary, cost-saving, bio-friendly system
designed to extend the life of fruits, vegetables, and flowers by
removing the ethylene gas and airborne pathogens. This patented system
works more effectively and efficiently than the ethylene gas removal
products that use potassium permanganate.
- S.O.L.E. Technologies products are currently being developed and
tested with multiple applications for the refrigerated shipping
industry, the floral industry, the consumer refrigeration market, the
consumer retail market, and the healthcare industries
