I ran across this little grill that designed in S. Africa as a safe cooking system. Kind of pricey, but interesting.
Cobb Premier Stainless Steel Grill

It's designed to use 8-10 charcoal briquets, and "...it will BBQ, roast, smoke, fry, grill, or bake for up to three hours."

"While its internal temperature gets hot (up to 500 degrees F), its exterior base remains completely cool to the touch..."

Interesting. Pricey. Thanks, Sue.
