I have one of the very latest type of BBQ,s its completely enclosed, like a big white box and works off mains electricity. Its designed to work inside your home, usually the kitchen.
The advantages are that you can control the temperature by means of a dial on the front of it, the food is fully enclosed so it can not be stolen by next doors alsatian, you can set a timer so it turns itself off enabling you to get on with something more interesting while the food is cooking, it hardly ever sets fire to the food or itself, the food does not taste of gasoline, you dont have to hurriedly convert to a pagan religion and offer a young virgin up for sacrifice in order to persuade it to start producing enough heat to cook with, and your food never gets wet in the rain.
Its called a "cooker", its the next big thing i reckon.
