Build your own radiator?

May be a little utilitarian, but - hey, if it works, it works! Gave me an idea for a short under the window pipe radiator. With some kind of cap to keep it together, this could give a lot of BTUs with a 1' pipe stack.

I've built a bunch of different radiators over the years. Everything from copper to concrete.
Hot water circulating through pipes, easy as that. Give it a try and show us your stuff. Here are a couple favorites.

@JohnNY has posted some tubular steel radiators being used in NYC.
The only problem with copper is that when it's shiny, it's output is low. I had a sheet copper radiant ceiling heater in my office, and I was seeing like a 2 degree delta across it. I painted it flat white with latex and the delta T jumped to 4 degrees F. Essentially doubled the output with the stroke of a brush.
Low emissivity...
