Electric Powered Car with small generator converted to act as an alternator? Gas going to be $7/gal by 2012???
4 independent electro-magnetic motors (similiar to Remote Control car motors) hooked up to a bank of batteries. The wheels/ i.e.m.m.s have pulleys (like on gasoline motors) which are connected by belts to alternators that recharge the battery cells while the vehicle is in motion. all the batteries are thin li-ion batteries that are slim so that they can fit in the chassis/body beneath the passenger compartment. the brake system is electro-magnetic using electrical pulses to slow and bring the vehicle to a stop. Down the center of the vehicle an independent cell of batteries and/or Heavy Duty capacitors to power the various other important electronics (headlights, taillights, etc.). there can be other pulleys in place for fans, hvac systems, so on. Acceleration can be controlled by transformers and switches linked to the accelerator pedal.
Obviously for larger vehicles and more hauling power the motors are going to have to be modified but here is a start.
“4 independent electro-magnetic motors (similiar to Remote control car motors) hooked up to a bank of batteries.”
all electric motors are electro-magnetic. just thought i’d say so. and the battery/batteries are a given, unless you want to be stuck following some sort of electric rail in the ground
“The wheels/ i.e.m.m.s have pulleys (like on gasoline motors) which are connected by belts to alternators that recharge the battery cells while the vehicle is in motion.”
good idea, but not that simple. the alternators would cause a drag, reducing efficiency and forcing the drive motors to use more energy to maintain the same speed. fan-powered alternators, powered by the relative wind created by the vehicle’s motion could work with sustained speeds, though
“all the batteries are thin li-ion batteries that are slim so that they can fit in the chassis/body beneath the passenger compartment.”
why not put them where the old gasoline engine was?
“the brake system is electro-magnetic using electrical pulses to slow and bring the vehicle to a stop.”
huge waste of energy. cut the drive motors and use a closed hydraulic system to apply friction brakes, just like we have now. and we already have ways of getting some electrical energy out of them, thus producing energy rather than using it
“Down the center of the vehicle an independent cell of batteries and/or heavy duty capacitors to power the various other important electronics (headlights, taillights, etc.).”
important stuff is stuff you’re going to use alot. might as well run off of the main battery. non-essential stuff, like a radio, A/C, power windows, etc, on the other hand, would use this idea very well
“Acceleration can be controlled by transformers and switches linked to the accelerator pedal.”
link the pedal to a current limiter that, well, limits the current, and therefor, speed, of the drive motor(s). much simpler, and the basic system already exists
“Obviously for larger vehicles and more hauling power the motors are going to have to be modified but here is a start.”
no, they just need bigger motors
and one more note: unless you include a ton of super-lightweight, super-effecient solar panels, you’d still need to plug in to recharge every so often, which we simply don’t have the infrastructure for yet. or put a small gas-powered engine in it to keep you moving while charging the batteries. super-high MPG is better than nothing, right?

Electric Wheelchair How To Pick One
An electric wheelchair is a chair powered by a motor. It is also called a power wheelchair. These motorized wheelchairs are ideal for people who need to use a wheelchair all the time. The average price of an electric wheelchair is about $3000. Some power wheelchairs are made for indoor use only and using them outdoors is rather dangerous.
Things to look at when buying an electric wheelchair
When buying an electric wheelchair, there are a lot of things to consider. You have to find a chair that fits your needs. Some of the features you should look at when purchasing a wheelchair are its weight, whether it is designed for indoor or outdoor use, its weight capacity, the power source etc.
To get an idea you can take a look at the electric wheelchair reviews posted below. These chairs are designed by lead wheelchair manufacturers.
Invacare Pronto M-50, M-51, M-71 series
These electric wheelchair models are small and easy to use especially indoors. They are recommended for indoor and limited outdoor use. The fact that they are small (38″ x 25″) and have a mid-wheel drive makes them easy to manipulate indoors, whereas the wider casters and the SureStep suspensions allow them to pass small obstacles.
All three models have a maximum speed of 3 mph, which is low for very active persons, but enough for home and nursing use. The seat is 17″ or 18″ deep. For the first two models, a semi-reclining seat is optional, while for the last one it is standard. The weight capacity also varies between the three electric wheelchair models. The M-50 and M-51 have a maximum weight limit of 300 lbs, while the M-71 has a limit of 250 lbs.
Jazzy 1103 Ultra with NP Controller
This electric wheelchair is designed both for indoor and outdoor use. It can be use by someone between 5’0″ and 5’10″ high. Like the Invacare electric wheelchair models listed above, it also has a mid-wheel drive. The Jazzy 1103 Ultra with NP Controller has a maximum speed of 4 mph. It has a power elevating swivel seat and an 18 inch turning radius. This electric wheelchair weighs 71 pounds and has a maximum weight limit of 300 lbs.
Other electric wheelchair manufacturers are Permobil, Redman Power Chair, Pride, Quickie, Falcon etc.
Electric wheel chairs have been out for a while now helping people get where they want and need to go, but when buying one you should take the time to research and test it before you buy. The thirty minutes of research might save you a couple hundred to a couple thousand dollars.
When looking for a certian chair you may want to consult a person who has used on before there is a forum at my website that you may be able to share or get some information please feel free to help yourself or others.
