If you combine two 110 volt power lines it does not give you 220 volts, the voltage will be the same. The only way to turn 110 volts into 220 volts is with a step-up transformer.
Typically they are either 220V or 110 volts not both. Plugging a 11o volt blanket to a 220 volt line has a huge risk of fire.
Unless the ballast is a multi tap primary you can not rewire it for 220 volts.
Not much of anything. The 220 volt appliance needs just that ... 220 volts in order to run. If it runs at all, it certainly would not be running at anywhere near peak efficiency.
True, 220 volt appliances consume less energy than 110 volt ones, but in order to use them in the US, you would need to convert them to 110 voltage. This is a less efficient use of energy. Plus, 220 volt appliances are a more risky because people can get seriously injured if they get shocked from them.

France uses 220-240 volts for their electrical system.

NO - that is dangerous.
The United States is one of the only places in the world that uses 110 volts instead 220 volts. In order to operate 208 volts on a 110 volt electrical current, you will need a voltage converter.
A 220 volt line may put out 250 volts because this specification features voltage that varies between 220 and 250 volts. In other countries, the electricity varies in voltage between 110-120 volts.

Plugging it into a 220 volt socket will probably destroy it.
you don't. you just take and use 120 volts from the 220. At least that's what I'd do.
A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts. A single phase three wire panel will give you 110 and 220 volts.
With a voltmeter Keep volt meter terminal on phase and neutral wire and it will show the exact volatage
The U.S. chose 110-120 volts because it is safer than 220-240 volts. Far less chance of getting electrocuted on the lower voltage.
