This one is for the automotive industry.
I have long been fascinated by an electronic component called the "Light Dependent Resistor" (LDR). It is a component that changes it's electrical resistance based upon the intensity of light incident upon it.
The concept is simple -
Use the LDR to control all the lights in an automobile so that conformance to lighting standards in a car is assured.
How
If we place, strategically, minimum two LDRs in the headlights and maybe one or two in the taillight zone, then we know from the resistance of the LDR the intensity of the ambient light.
This knowledge can then be used to control all of the following -
1. If and when the headlights should be switched on.
2. If and when the fog lights (and all other lights) should be switched on.
3. The intensity of the headlights and the fog lights (and all other lights).
4. The status of the headlights - should it be on hi-beam mode or down on the road.
5. If and when the rear view anti- glare position must be switched on.
6. There can be further refinements like introducing anti-glare features in the side rear view mirrors and many more which I shall leave to the imagination of the readers.
If nothing, implementation of this innovation, will save a lot of switches and wiring to the steering wheel, improving the reliability of the car as a whole.
The circuitry is actually very well known and simple, and widely available in the net. You can get the basic circuit by typing "Light Dependent Resistor Circuit". But, like in most automotive innovations this is either already accomplished and withheld for cost purposes or possibly neither.
I, however, have not thus far, seen a comprehensive lighting control patent in an automobile based entirely on ambient light sensing through LDRs.
Another use that I have long since felt the urge to share on this same topic is the control of street lights using the same concept. However, I feel confident that this is a known innovation in the developed world. In India , where the switching on and off of street lights in cities is still manual and open to the vagaries of the person on duty this could possibly be mandated by law, not from a electricity saving point of view but from a "safety" point of view so that light is available at the time it is required and in the correct intensity.
More later, Happy Festival of Lights!

Do you know Sam Pitroda? I think he is the guy you should get in contact with and give some practical shape to your seemingly impractical solutions to many problems. Difficult is what you can today impossible only takes a little longer......
