Supercharged V8 fireplace - video

Around 'chere, firepits and chiminea are in 90% of residential backyards. They radiate heat nicely; some are steel, others are masonry.
With the exhaust loosing heat post fuel, there won't be much forging, the box isn't too shabby. That he fabbed a block, manifold, and a blower elevates this w-a-y above mine.
Butt end of a 1000 gallon [41" diameter] propane tank on stacked pavers. I didn't cut it, found in long gone scrapyard. Cleverly, bottom hemisphere was cut out about 12" diameter, reversed and tacked back in. Doesn't hold a drop of rainwater.
Sometime I need to build a wire cooking grate for it, slap 30 pounds of steak aboard and invite folks over. She can eat all the junk mail around and light up 5 pieces of 8 or 10 inch oak readily.
