Electricity is very useful and it's not so easy to replace it, but it is possible to create a car that doesn't use electricity anywhere and still have many of the modern car accessories.
As we know a diesel engine doesn't need electricity for ignition, but it still needs electricity with many of its functions.
We can use compressed air instead electricity to run functions of a diesel engine
NON-ELECTRIC DIESEL ENGINE
In the picture there are a battery, a battery charger and an electric starter replaced with a compressed air tank, an air compressor and a starter that works with compressed air respectively.
Also electric glowplugs are needed to replace somehow. There is no ready made construction for that, but it supposed to be possible make one using kerosene and compressed air.
There are also many pumps related to a diesel engine. It's possible to make pumps working with compressed air.
One of most difficult thing to do is create usable light for car usage without electricity.
Using a pressurized kerosene (paraffin) lamp it's possible to create very bright light. Its gas mantle is fragile and additional development is required to get it stand long enough in car conditions.
It would also be possible to use friction to produce bright light. In this case compressed air would be used to rub two metals together. This is probably even more unpractical than a pressurized kerosene lamp.
In the picture we can see a modified pressurized kerosene lamp. The light is transferred forward using optical fibers. Compressed air is used to control lights. The controls are in a dashboard.
In spite of a engine and lights in a car there are a lot of things using electricity. Some of them are possible to replace with non-electric methods like compressed air, hydraulics and mechanical methods and some are not.
Examples of those that are possible to replace (compressed air):
- windscreen wiper
- windscreen washer
- air conditioner
- power windows
Examples of those that are not possible to replace:
- car stereos etc.
- car computer
- satellite navigator
- cell phones
