If you like to barbecue on an open fire and nevertheless want to do it with zero point energy, use a HHO-converter, which is fueled with water. Simple tap water is sufficient, of which the molecules are separated into so-called Brown's Gas with the help of zero point energy. This gas is good to do heating, welding and barbecue and everything, including brazing, which is done with open flames nowadays. We can further apply our existing know-how in dealing with open flames, even when we work with zero point energy. By the way, this can also be used to operate a cozy open fireplace in the living room - for the cozy winter night when it's snowing outside.
Of course it is nice to sit outside with friends at a barbecue on a balmy summer night. But what about on a cool spring night or a crisp fall night? It's simple: we can sit around a campfire, or a zero point energy outdoor heater. As everybody knows, energy does not cost anything.
