What are the desirable characteristics of an ideal barbecue grill according to the author?

I - A fixed barbecue grill should have at least two parts, one for the fire that will provide the embers and another where the food will be placed.
II - The fire area can be simply an empty space properly lined with refractory bricks to withstand the high temperatures that will be generated there.
III - The grill should be at waist height of the grill master, which allows for comfortable placement of food and turning or basting.
IV - The grill should have a crank to lift it up and down.
V - The hood should be a gradual reduction of the walls of the barbecue grill to end in the flue or chimney, which must be open to the four winds and at least 1.50 m above the highest part of the roof or surrounding structures.
VI - The grill should be made of stainless steel or enameled iron.
VII - The grill should be placed on a concrete slab.
