I wondered about that last point. Certainly there is more area and
less heat per gap. By the way, in the cylinder gap I have here (only 7
pieces of 3/4" pipe, mounted on ceramic standoff insulators and then on
an aluminum plate) I mounted the thing so the cylinders were vertical,
which should give at least a little convection cooling.
