You have to use electricity to recharge your battery.
How you get the electricity doesn't matter.
There are now commercials on tv about alternative power generators, using LP or natural gas, so that when power goes out, you still have your power to your house thru natural gas generator.
The generator is built to reproduce electrical power coming into your house, so it'd be no different for you to recharge your batteries as it would by merely plugging them into the wall socket......because YOU'D STILL BE PLUGGING THEM INTO THE WALL SOCKET. The only difference is how the elecricity getting into your house and garage is made.
So basically, there's no problem, there's nothing to worry about.
You cannot burn natural gas and get an electrical current, you have to have something inbetween in the process where the gas being burned, it's heat moves some kind of machinery, such as thru water transfer, to turn a generator, which makes the electricity. Many huge power stations across the country, take water power, boil the water to make steam, which then turns turbines, turning generators, which then produces electricity.
It's not a new idea, it's been around for 100 years easily.
Sure: natural gas generator to operate a battery charger. But would be easier to plug a charger into an electric outlet.
Natural gas can be used in either of two ways to generate electicity, which is what the car batteries need. It is not clear whether you are talking about the starting batteries in conventional cars or battery banks in electric cars but it all works out the same.
Natural gas can be used as fuel in most combustion engines, such as ones that power generators. It can also be used in fuel cells such as the example in the source.
natural gas and a spark goes boom. not going to work if you want to put natural gas in your battery.
Generators can be functioned by using natural Gas now a days, I am intended to ask whether its possible to charge car battries by natural gas?
