Making EVs

While Lowering Their CO2 Emissions

     For at least 30 years politicians. and several lobbying groups have been perpetuating the myth that battery-powered EVs (BEV) are "Zero Emission Vehicles.  Recently, they formed a lobbying group by that very name and their goal is to encroach on people's freedom and grant a monopoly on all "motive power" to the people who own the world's large utility companies.    See:  Needless to say, there is a large public backlash to this erosion of human rights.
           If we ignore the health-damaging toxic gasses emitted by the grid and just look at the non toxic CO2 emission it becomes clear that the typical BEV charged by the grid has a much larger "Carbon Footprint" than a comparable IC powered vehicle.  Using studies by academician, government bodies, and professionals cited on several of the following pages the analyst below is a comparison of the CO2 emitted by a 2022 Toyota Camry, 2022 BMW 320 I and a 2022 Tesla Model 3 with 100 kWh battery pack which has a useful life of 100,000 miles.
The 2022 Camry using regular gasoline has
upstream and tailpipe emissions of 335 grams of CO2/mile.

The 2022 BMW 320 I using regular gasoline has
upstream and tailpipe emissions of 370 grams of CO2/mile. 

Tesla model 3 with a 100 kWh battery emits 483 grams of CO2/mile when charged by a natural gas plant or 637 grams of CO2/mile when charged by a coal plant.  Calling an EV charged by the Grid a "Zero Emission Vehicle" is a lie of mythical proportions.  
The calculations are below.

Natural gas generated electricity              = 600 grams of CO2/kWh
Transformer & distribution loss 11%       = 666 grams at charging location
Charging efficiency 85%                             =  765 grams after charging
kWh used per 100 miles                             =  30 kWh
Kg of CO2/100 miles                                    =  22.86
Grams of CO2/mile                                      = 229
Kg of CO2/kWh of battery                           = 254 kg/kWh
Kg of CO2 for 100 kWh battery                  = 25.4 metric tons
Amortized CO2/mile                                     = 254 grams/mile
Total  Natural gas power                            = 483 kg of CO2/mile

Same calculation with coal                         = 1,000 grams of CO2/kWh
Transformer & distribution loss 11%        = 1,110 grams at charging location
Charging efficiency 85%                               = 1,276 grams after charging
kWh used per 100 miles                               = 30 kWh
Kg of CO2/100 miles                                      = 38.3 KG
Grams of CO2/mile                                        = 383 grams/mile
Battery  CO2/mile  (as above)                      = 254 kg/mile
Total with coal generated electricity           = 637 kg of CO2/mile

    Kamtech SA. has a technology that creates lower CO2 than BEVs, IC, and hybrids, the Kamtech Range Extender.  The attached graph (slide 3 above) from a recent study illustrates the total lifetime CO2 emissions of electric vehicles  (BEV) conventional vehicles and REEVs, including the CO2 emitted by the mining and manufacture of an EV's battery pack.  This graph clearly demonstrates that an efficient REEV generates far less CO2 in its lifetime than any other vehicle type!  A Kamtech REEV is also less costly, safer, and can have a far greater range than any other vehicle type!    See: slide #3 source is 
    In response to this lie by the  Zero Emissions Vehicle Association, many government bodies in various parts of the world are planning to soon outlaw the private ownership of all vehicles powered by internal combustion (IC) engines, claiming that this will somehow change the climate for the better and as a result, the world will only have blue skies every day!

     Needless to say, most people are not buying the lie!  The source of power for most BEVs is the electric grid which is far worse for the environment, and people's health than modern vehicles which are powered by IC engines. The adoption of BEVs will actually produce enormous environmental damage to the climate and the earth's air quality.

    More than 99% of electric vehicles today draw their electricity from the world's grid.   More than 80% of that energy comes from fossil fuels, about half from coal. Most of the remaining 20% is from hydroelectric plants that have man-made lakes that generate large amounts of CO2 from the rotting biological materials in them. see: 

     According to the American Lung Association, the energy coming from these electric utility plants is far more harmful to people's health than automotive emissions, which are mostly non-toxic CO2. They observe that on top of their massive amounts of CO2 emissions "natural gas, oil, and biomass power plants also emit significant (toxic) air pollutants. These emissions include sulfur dioxide, nitrogen dioxide, and carbon monoxide, as well as hazardous pollutants that can cause cancer and other health problems."  Is health not a large concern to the lawmakers that are pushing to give utility companies a future monopoly on all motive power? 

    Each BEV is also responsible for up to 25 metric tons (55,000 lbs.) of CO2 being emitted into the environment before they are even connected to the electric grid.   In 2017, a Swedish government study looked at how much CO2 is emitted by the making of BEV's battery packs of different sizes. The study found that the extraction, transportation, and production of EV batteries released between 254 kg and 270 kg of CO2/kWh into the planet's atmosphere.  A BEV with a 100 kWh battery is responsible for more CO2 emissions than 10,000 liters of gasoline before its leaves the factory.   This is equivalent to the fuel used to drive a Toyota Camry well over 80,000 km. see: slide #3

     Charging an EV with the electric grid is also very thermally inefficient. Only about 35% of the heat energy used by the grid is converted into electricity, which means 65% is vented into the air, directly warming the atmosphere.  Each kWh produced by coal or petroleum emits between 600 to 1000 grams of CO2.  see: 

     The grid’s distribution losses (including transformer losses and line losses) can be over 10% so thermal efficiency drops to about 31.%. An EV charging system lowers efficiency by another 14%. So overall efficiency is just 27% and each kWh that went into the battery is now responsible for up to 1,300 grams of CO2 being vented into the air.  (Note: Technical losses are normally 22%)  See: 

     Testing by Forbes found that one kWh will move the average EV 4.6 km or 2.9 miles, which on average would be close to 300g/mile.  But, how does that compare to gas-powered vehicles of a similar size?

     A study by Technology Analyst, John Peterson noted that "Readers will be shocked because my conclusion is 180 degrees out of synch with Tesla's sustainability mythology. Frankly, there's simply no reason for investors, politicians, or governments to support vehicle electrification if EVs offer no appreciable environmental benefit."  He further noted that "analysis shows that Tesla's long-range Model 3 has a 24% heavier CO2 footprint (278g/mile) than the Camry Hybrid LE" (211.1/mile). 

     When a Kamtech's RE is installed in a vehicle the size of a Tesla Model 3 it is estimated to consume only two liters of gasoline per 100 km.  Two liters of gasoline produce 4,600 g of CO2 or just 46g/km converted to g/mile you have just 74g/mile.   If Natural gas is used as its fuel then only 40 grams of CO2/km is emitted.   How can a Kamtech-equipped REEV be so clean?

     Magical thinking dominates electric vehicle discussions.   This is why advocates call them Zero Emission Vehicles!  Omitted is the fact that BEVs just shift their much larger CO2 emissions to the distant electric generating plants which also emit highly toxic pollutants, heat and water vapor into earth's atmosphere.  Also ignored are the tons of CO2 emitted to make their battery packs. The goal of such magical thinking is to foster the misconception that BEVs will "save the planet".

      In contrast a Kamtech RE powered EV has a significantly lower environmental, and social cost to our planet than either a BEV or a ICE powered vehicle, it is able to do this by:
  1.  Reducing by 80% the cost, and CO2 emissions related to making its battery pack..
  2.  Reducing the CO2/kWh by almost 50% using the Kamtech radial cam engine
  3.  Increasing its range by up to 40% by heating the interior with waste heat.
  4.  Eliminating the distribution, transformer, and charging losses inherent in grid power. 
  5.  Reducing the charging and discharging losses via directly using its electricity .
  6.  Eliminating society's need to build hundreds of new powerplants to charge BEVs.
  7.  Eliminating the need for government subsidies for rich buyers by lowering costs.

   Kamtech's core technology is an ultra-efficient internal combustion engine design. Its proprietary cam design produces a piston dynamic that allows time for fuel to be completely oxidized inside the combustion chamber rather than inside a car's catalytic converter, where the fuel's final combustion only produces heat not work or power.

     Kamtech's Radial Cam Engine uses Homogenous Charge Compression Ignition, (HCCI). This is a combustion process that eliminates the super hot flame front found in all traditional IC engines. HCCI technology combusts the fuel in an instant at a lower temperature. This process prevents the formation of NOx. It also uses several other proprietary methods to improve the combustion process and increase the thermal efficiency of the engine.

     The Kamtech engine’s combustion chamber uses high-temperature, low-thermal conductive materials which allow for a lean burn without the worry of burned valves or melted pistons. All of these features allow for more of the heat energy to be converted into work, rather than heat load for a cooling system or a red-hot exhaust system.

     The result is an engine that is:
  • up to 90% more energy efficiency,
  • in a 50% smaller package,
  • while having 60% fewer parts,
  • The Kamtech engine is also about 50% less costly to manufacture and
  • Has a longer life than a traditional Otto cycle engine.
     Kamtech's engine design is also perfectly balanced and runs as smoothly as an electric motor. Our Rad-Cam engine is a radical departure from the 160-year-old Otto cycle engine which is standard in most vehicles today.
      Any new technology must integrate itself into the lifestyle and expectations of the market if it is to become mainstream. The Kamtech RE is especially suited to do just that.

Kamtech equip REEV can operate on a variety of fuels. Besides gasoline, which can be found almost everywhere, it can also run on compressed natural gas, which is piped directly to hundreds of millions of homes in the developed world.  It can also use one of the fuels that are now considered to be Zero Emission, like methanol, or biogas. This would make a Kamtech REEV truly a "Zero Emission Vehicle".

      Kamtech’s “Range Extender” can easily be integrated into several new vehicle designs, to fit the lifestyles of all market segments. New REEV designs can be lowered by 10-12 cm as the smaller battery pack no longer need to be under the whole floor. The small size and light weight of Kamtech's RE allow designers to place it in response to function or style rather than just under a long hood.  This allows for better balance and lower vehicle's weight, which means faster stopping and better handling.  

Kamtech-equipped REEV waste heat can warm the cabin without loss of range. This problem has caused thousand of EV drivers to finish their winter trips on the back of a car hauler, or to shiver in a cold car for several km to save range.

ecause it can be refueled at any petrol station its owner will never suffer from “range anxiety”! The small Kamtech engine can also be used to directly power an air conditioner compressor. Kamtech's RE brings the mental and physical comfort of a gas-guzzling car to the EV world, while at the same time causing far less CO2 than the most efficient BEVs.

he Kamtech-equipped REEV does all this with a battery pack 1/5 the size and weight of a standard BEV. This makes it a perfect fit for a world wanting to lower its CO2 emission.  Using a smaller battery will lower EV manufacturing cost significantly, thereby expanding the market.  

inally, a Kamtech-equipped REEV can provide emergency power to the owner's home in case of a regional utility power outage. This ability may be an important marketing advantage as climate change and the move to renewable energy sources are expected to make local and regional power outages more and more common in the future.

ll these features make a Kamtech REEV a much better fit into the automotive market than any EV, hybrid, or ICE-powered vehicle.
    Our passion for making vehicles more efficient and user-friendly has pooled the ideas of several innovative people. They included a world-renowned combustion engineer whose background included working for NASA, a world-famous mechanic, whose many patents helped shape modern automobiles, an aircraft engineer who continues to pioneer new ways of powering aircraft, a mechanical engineer from Silicon Valley, and a young Vietnamese Engineer.

     After decades of work and several prototypes, we are now ready to offer to the world a far cleaner, safer, and more efficient energy source for EVs than grid power.  The Kamtech Range Extender is small onboard electric power source that can replace 80% of a BEV's batteries.   We did not invent the Range Extended Electric Vehicle or REEV concept, however, we did develop a technology that will make it far more practical than traditional power sources.

     A Kamtech REEV is unlike any of the many hybrid EVs which use large off-the-shelf engines connected mechanically to the drive train.  Kamtech's stand-alone generator only produces electricity, but it does it cleaner and more efficient than the antiquated steam engines used by the electric grid.  Unlike these power sources it is not oversized nor does it ever idle or run on standby. Unlike the engine in a hybrid, Kamtech's RE is sized to the average needs of a vehicle, not it's maximum needs.  It only operates at its maximum efficiency, and only if there is a need for power.

     The Kamtech RE is always there as a redundant backup so there is never a danger of getting stranded, or suffering "range anxiety".  It is the perfect power source for any size Electric Vehicle from sports cars to buses.  

The team behind the six prototypes that have painstakingly been conceptualized and slowly developed over the two and a half decades have been the late UC Berkeley professor Antony K. Oppenheim,  Florida based mechanic, the late Smokey Yunic, mechanical engineer Jim Duncalf, aircraft engineer Mark Beierle  of Earth Star Aircraft Company and the latest team member engineer Pham Duy Tung who resides in Vietnam.    

The first 2 prototypes were built by Jim Duncalf in California. The next three were built by Mark Beierle and his staff with design assistance by Jim Duncalf. The last material test prototype was built in Ho Chi Minh City, Vietnam by Phom Duy Tung and Jim Duncalf.

The current design has also had significant design input from professor Huynh Thanh Cong, Lecturer, Internal Combustion Engine, Ho Chi Minh City University of Technology.
