If the paint could collect solar energy to charge a battery, and then once the car starts moving, other fibers in the paint could convert the wind passing over the car to electrical energy, wouldn’t this be a way to decrease our dependency on fossil fuels. Is there any technology out there that can do such a thing?
May-be, with nanotechnology solar paint and nanotechnology windmills.
Wind, no. If the car is collecting energy from wind, that means the car has to use more energy to move and "make" that wind. Even if that system were 100% efficient (it would not be) it would not net any energy gain.
Photovoltaic paint exists, with existing technology it could be used to extend the range or slightly increase the efficiency of an electric car. If photovoltaic paint can be made more efficient (i.e., to capture more energy from the sun), solar cars would be much closer to reality. Solar cars are cool, the major solar races have had to modify their rules because solar cars keep bumping up against the 65 mph speed limit.
Yes No and maybe. nanosolar developed a photovoltaic paint before they were bought out. no paint can convert wind power to electricity. and maybe, if you meant power a small electric fan then yes if you meant to power the wheels no. Average EV motor uses continuous about 29 kw (29000 watts) with a peak around 50 kw. a cars entire surface being photovoltaic could produce about 200 watts continuous.
yes and no. but really, no.
there is an annual solar car challenge, but none of the contenders is street legal, and would completely shatter if they got into an accident.
besides the solar panels are large, and don’t generate all that much energy.
you’ll see people who want to sell you instructions to make your car run on water.
you’ll see people who want to sell you instructions to make you energy independent.
consider, if either of those was really possible, wouldn’t it be at the top of every newscast in the nation?
really.
wouldn’t china and india and all the poor nations that cannot afford coal and oil be doing it?
it really does not work.
and it never will.
any energy you extract from air flow past your car slows it down.
if you add up all the energy that falls on the footprint of a car, it’s only a few hundred watts.

<<The original 848 cc engine from the Morris Mini-Minor was given a longer stroke to increase capacity to 997 cc, boosting power from 34 bhp to 55 bhp (25 to 41 kW)>>
that’s an order of magnitude off at least.
it really isn’t going to work.
As of now, no. But scientists are currently running a broad range of experiments in the field of nanotechnology. They have already used nanomachines to destroy tumors and they have developed a nano-tech LED paint for making paper-thin televisions. I’m certain that soon enough, they’ll be able to do pretty much anything they want.
No. Air drag is one of the chief components in auto efficiency. What you describe would increase air drag.
As far as the solar part goes most cars have about 12 square feet of surface in the sun when the car is in the sun. 12 square feet can produce 900 watts. In four hours that would be 2700 Watt hours. A gallon of gasoline is about 37,000 Watt hours. What means is is that it is going to take over 100 days to produce the energy of one gallon of gasoline and everything has to be perfect.
I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills. It was written by a Renewable energy enthusiasts Michael Harvey the diy called Earth4energy. You can get your copy to save energy and help environment while eliminating your power bills.
