I got the idea for the Combo Electric Car from studying the Boomerbuggy combo scooter that uses two charging systems: electric and solar.




There is one main problem that I identified in the current electric cars that are deterrents in making the car attractive to mass-market consumers: driving range is too low.

I have come up with a solution that would help solve this problem.

Solution: Multiple charging systems

The “Combo Electric Car” would use two regular car batteries. It would NOT use Lithium batteries which are dangerous if they catch on fire. The car would have three different ways to keep the car’s batteries charged at all times and run the generators in the car that makes on-the-spot electricity that the car uses while in operation. This would give the car an “unlimited driving range”.

You need to imagine how the Combo car works. First, there are ordinary car batteries that start the vehicle and get it moving. Second, there are three systems that can create on-the-spot electricity while the car is in operation. The first one is wind power. This looks similar to the fan in a gas-powered vehicle, except the fan is connected to a dynamo generator. When the fan spins faster and faster it creates electricity through the dynamo. The second one is solar power. The roof, hood, and trunk lid are all outfitted with solar panels. These gather solar rays that create electricity through their solar cells. The third one is friction power. All the wheels on the car have friction generators that use the spinning of the wheels to create electricity while the car is in operation. These are similar to the generators that work on a bicycle to create electricity for a headlight on the bike, except they are more robust.

The important difference between Combo and other electric cars is that it doesn’t have large Lithium batteries that store electricity and rely on these batteries for running the car. The two ordinary car batteries are only used to start the vehicle.

If the Combo car worked, it would use no fossil fuels at all plus it wouldn’t need to be charged at an electric charging station. The car would be designed to create its own electricity that is needed to operate the vehicle. It would be a self-sufficient vehicle that would have no dependence on fuels or powering sources.

In addition, information is vital to new electric-car owners. For example, if the CEC was for sale it would provide detailed information on things like: how the car basically works, how to get the car serviced, what insurance coverage is needed, how to find the nearest CEC service center, and how to get options added to the vehicle. This information would also be abbreviated and placed in full-page ads for interested consumers. When potential customers know exactly what they need-to-know, they are more likely to make a purchase than to wait until they have already bought the car to find these things out.




I believe it is the “driving range” of an electric car that will ultimately determine its mass-market success on the car market. The driving range must be significant before ordinary customers will buy an electric car. Also, the car needs to be independent. This means that it can’t always be always tethered to a docking station to be recharged. It must be mobile to be a true “automobile”. Most current electric cars have about a 200-kilometer driving range. The Combo Electric car would have an unlimited driving range before it was made available.

The “Combo Electric Car” would be an electric car that would have four separate systems for recharging the batteries. The combination of these four different charging methods would give the car a much longer driving range than Lithium-battery electric cars. Keep it in mind that the only amount of electricity that is needed to be generated is enough to keep the car-batteries charged fully while the car is in operation. These batteries would run the electric motors and all the car accessories.

The following are ideas for the charging systems:

A)  Solar panels embedded in the roof and/ hood of the car that charge the batteries on sunny days and works both while the car is in motion and when the car is stationary. The solar panels could be extended outward to catch more rays; this could be done only when the car is stationary. No fuel is required.

B)  A crank-powered generator that uses the motion from the wheels of the car to create energy which, in turn, is used to charge the car’s batteries (see image below). Works while car is in motion. This method is similar to crank generators used on bicycles except they would be more robust. No fuel is required.

C)  A free-moving fan that generates wind power to create electricity and works while the car is in motion. The force of the car moving forward spins a fan around that is positioned in behind the grill (similar to how a windmill works in a garden when the breeze blows it). This fan, in turn, spins a small belt which, in turn, runs a dynamo generator (energy-maker). The energy create from this generator is used to recharge the batteries. No fuel is required.

The drawing is a simple diagram of a dynamo electricity generator. Where the wheel is, the fan would be.

Note: Each energy-making system must be kept separate from the other ones. Each one should have its own battery to store electricity. The reason why is to prevent short-circuiting of the systems.

Note: Static electricity is the enemy of the electric car. A device for absorbing or removing static electricity would be installed in each vehicle.




·        Multiple-charging systems keep the car’s four batteries fully-charged at all times. This gives the car an “unlimited driving range”. These systems would include: solar charging, wheel-friction charging, and wind-power charging.

·        Dual electric motors that work independent of each other. If one motor fails, the other motor automatically takes over. This means the car would always be operational.

·        Front and back brakes that work independently of each other. If one set failed, the other set would still work. Then there would never be a time when the car had no brakes.

·        All of the electrical components and motors would be “water-proofed”. Since water is hazardous to electrical motors and systems, water-proofing in the CEC would help make the car fail-safe. This makes the Combo car somewhat flood-resistant which means you could drive the car through two feet of water, if you had to.

·        The car would have a customizable anti-theft system so the owner could create their own alarm. “Hey, you! Get away from my car!” Also, when the security alarm on the car is activated, because of an attempted break-in, hidden web-cams around the car would come on and take photos of anything or anyone near the vehicle. These photos would be sent to the owner’s home computer or smartphone, so that if it is something serious, they could call the police.

·        Every car would be installed with two hidden permanent GPSs in locations that only the authorized service center could find. These will be tested at each annual car-servicing. The GPS could be operated from the owner’s smartphone or home computer.

·        The car would come as a basic no-frills model that would be affordable to even low-income people with a recommended price of $15,000 US. Add-on features, such as air-conditioning, stereo, and heated seats, would be included with the basic model but each one would require a password to activate. These passwords could be purchased online at the car company’s website. Add-ons could also be activated at the annual car-servicing.

·        An annual car-maintenance plan would include battery-replacement, if needed, and a complete inspection. Any repairs would be additional costs. Batteries and add-ons would also be extra. The basic servicing fee would be: $300 if the owner books the appointment within 12 months or $500 if the appointment is made after the deadline.

·        The company’s website address would be embedded on the back of every car to promote sales. Eg. ComboCar.com

·        The car would be purchased online at the company’s website with monthly payment plans available. All the passwords for the add-ons would be available through this website. A map of all the service centers would be kept up-to-date and available as an app. Appointments for annual maintenance could be made through this website or at the nearest authorized car-service center.

·        The car would be manufactured in several locations around the world. The head manufacturer would be in Alberta, Canada. You could also have “franchise factories” in different locations in the world. This keeps the car cheaper because it doesn’t require overseas delivery.

·        There would be no dealerships since the car would be purchased online.

·        There would be many authorized service centers. These could be independent or they could be part of current service centers, like Canadian Tire Service Centers or Speedy Muffler. This latter part would be arranged and negotiated. Also, training would be provided by the company on how to do the annual servicing and any repairs.

FREE: Each car would come with a complimentary “Windshield Car Shade” that is made to repel the heat from the Sun. There would be a www.combocar.com and the company logo across the front of it to help promote the car.




·        This car would be similar to other cars except that the systems in the car would be adjusted to the real experiences of driving.

·        The speedometer would show speeds in the Normal range of most driving, from 0 Km to 120 Km. 

·        The car would not be able to travel faster than 120 km per hour.

·        All the speed increments would be shown on the speedometer: 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, and 120.

·        The car would have “Speed Control”. This would be a push-button system on the dashboard that the driver could quickly control while driving. For example, when the 50 Km button was pushed, it would light up, and the car would not be able to drive faster than this speed. There would be a Cancel button by the steering wheel so the driver could cancel this quickly, if needed. Note: This is NOT the same thing as cruise control.

·        The programming on the Speed Control would have a timer on it. This is so the police can override and program the car to only be able to travel at a maximum of certain speed for a certain number of days. For eg. 60 km/hr for 90 days. Then speeders who are caught would only be able to drive around town and not on the highway.

·        The car could also be permanently programmed to not drive faster than a certain speed. This is to help parents make sure their young drivers don’t drive too fast. This would be a password-controlled system.

·        The side mirrors would be able to fold into a compartment when the car was shut off to prevent damage done to them.

·        The windows would have two control systems for closing and opening the windows: a manual wind-down and an automatic button.

·        The car would have a Crash Shield around the circumference. This is to tell the driver if they are getting too close to another car or object that might result in a crash.

·        The car alarm system can also be customized to emit a sound of the driver’s choice. There would be a range of choices. Examples are: the sound of an electrical short-circuit with flashing light coming out of the driver’s window, a vibrating noise, a low growling sound of a large dog, or a customized voice message (“get away from my car before I call the police”).

·        There would be two horns: a standard horn on the center of the steering wheel; and a beeper horn, that emits a quieter sound to gently warn some and is located on a button at the end of the wiper-blade lever.

·        Rodent-proofing so that small animals can’t eat wires or invade the vehicle. Eg. No soy-coated wires.

·   The inside door locks are encased by a flip panel which prevents the door from being unlocked by a Slim Jim tool.

·   The built-in car-stereo system would have Bluetooth capability and would also have groups of pre-programmed music selections, such as: sixties music, rock and roll, easy listening, classical pieces, country classics … and so on.

·   The car could be used as a mobile generator (like Ford’s F150 2021 pickup) to provide power during an outage.

·   There would be pull-down blinds over each of the car windows, like they have on airplanes.

Every aspect of the driver’s experience when driving the CEC would be ergonomically assessed and designed. This would include: the comfort of the driver’s seat for long-distance trips; the easy of opening and closing doors and windows; checking mirrors; the accessibility and ease-of-use for all the control knobs, levers, and switches, and the sense in touching the accelerator and brake pedals. The idea is to get an optimum UX experience for all drivers of the CEC.



I recommend that three manufacturing facilities be set up to make the Combo Electric Car: Calgary (Canada), and two other places in the world that are safe zones.

The reason why I chose Alberta is in case the Combo Electric Car replaces the standard combustible-engine cars and this results in the reduction of the mining of fossil fuels. It would give oil-workers in this area alternate employment, in the event that the sales of the Combo Electric Cars causes a reduction in oil production.




Once the CEC company is successful, it should set up and operate several car-recycling facilities that break down older or discarded vehicles to reuse the parts or melt down the scrap metal. This will help reduce the number of abandoned vehicles that junk up our beautiful environment. These facilities would recycle both combustible-engine cars and electric vehicles.




The only test that would be done on CEC prototype vehicles would be for NORMAL operations. There would not be an extreme testing or crash testing of CEC prototypes. This is so the main focus on the car design is for normal use under normal conditions.




In the following examples, turbines are for cycles or assembly lines.

Turbine A: Car Assembly Line. This I when the parts move along the assembly line and the vehicle is put together using both human workers and robotics.

Turbine B: Worker Positions Line. This is when workers are trained for several positions and are schedule to work in them in a rotation.

Turbine C: Shift Hours Line. This is when workers switch from a day shift to an evening shift. There would be no night shifts in the CEC manufacturing facility.

The purpose of the turbines is to stop boredom and prevent injuries due to repetitive activity. It also creates a fairer workplace so that some workers are stuck with the lousy jobs; they are shared by the group.

·        Electric motors that run the car

·        Dynamos that generate electricity

·        Self-charging systems

·        Power storage cells

·        A generator

·        Car components

The electricity the car generates from the charging systems is very valuable and therefore must be used wisely. There should be a “power-drain detection” system that alerts the owner to any power leaks or high power consumption of a feature or device. The owner should be able to shut off any power leaks when turning off the car. Power budgeting would be part of the design of the car so that most of the energy created would go to the motors that drive it. Other features and devices would only have lite power requirements.

There could be a dual-power-generator system in the car similar to having two electric motors. It is a fail-safe system so that the car will always be able to operate.

One of the charging systems in the car could be a portable one. This system could be re-charged inside the house and then taken to the car when needed. It would be high-powered florescent lights that would charge the solar panels during dreary days. I noticed that it is the light that solar panels utilize, and not the heat, from the Sun. So, I thought of florescent lights (like the curly light bulbs) because my plants love them and do well in the winter months (when there are less sunny days) when I leave these lights on for them.

There should be large button-switches with large labels that are easy to read.

There should be a developed trouble-shooting system:

·        Small alarm when something is wrong

·        Red light on the panel shows

·        An explanation of what is wrong

·        What to do to fix it

The secret to the success of the CEC is in its ability to make its own electricity that will run the car and all of its components.


Is it possible to design a storage cell that is in itself run by electricity?

Can this storage cell be kept charged up as well?

The aim is to have the smallest amount of electricity required to maintain the systems that run the car.

I believe the secret to the success of the CEC lies in the system that is used for creating and storing power to run the motors and the components. This system should be perceived as a singular unit that works harmoniously together.




Once a person buys a CEC, they want to be able to maintain it effortlessly and relatively inexpensively. It is always a hassle for car-owners to take their car to a mechanic for repairs. I had the idea that when designing the actual layout of the car’s internal parts, there should be as many “plug-and-play” parts as possible; then car-owners can buy the replacement part online and when it arrives, replace the broken part themselves – without having to go to a mechanic.

The basic fee for doing the annual servicing would be $500, if the owner brings the vehicle in within 12 months of the last appointment. If the car is brought in after the 12-month deadline, the fee would be $750.

What would be done:

·        Complete inspection of the car.

·        Top-up of any fluids or fuel as required.

·        Cleaning and lubrication of any movable parts.

·        Solar panels cleaning.

·        Battery replacements.

·        GPS testing.

·        New add-on options activated.

·        A list of any repairs that need to be done.

The cost of repairs, and parts, would be extra.

Each customer would receive a 500 ml bottle of Whoosh Screen Shine Pro and a 4-pack of cleaning cloths for cleaning the car’s solar panels throughout the year.




Once the company has finished the prototype and is ready to sell the first model of the car, it can test sales to see if the car will become popular. If the car shows signs of popularity, then the company can hire a spokesperson that can help do commercials and videos to promote the CEC. This person would be paid $1M plus 1% of the sales of the CEC for 5 years. For example, I thought the Canadian singer Serena Ryder would be a good choice and to use her song Electric Love in the videos as a background. https://www.youtube.com/watch?v=G7i0cYlIqmY


I had the idea to set up a system that allows other car-manufacturers to make the CEC and, in exchange, give the mother company 2% royalties of all the sales that are made. This would encourage the sales of the CEC on a global scale. A contract between CEC and the other car-manufacturer would have to be drawn up before this would become active.


Another idea is to sell the car through third-party sales at Amazon. The shipping costs would have to be built into the price of the car.

Remember, these are concept ideas only for the Combo Electric Car. It may or may not be a feasible product to make.
