I had to google it, I had no idea what it was. I found this:
Induction cooking - Wikipedia, the free encyclopedia
I like that any pots & pans can be used to cook with pretty much. So you don't have to buy new cookware.
So you need a vent hood for a gas cooktop? I had no idea. See how clueless I am? LOL We have electric since we do not have natural gas in our area. I would LOVE a gas cooktop though.
