Heat deflector over the top of the rocket stove pipe?

Will adding a heat deflector over the top of a rocket stove throw the hot air outwards at all do you think?

I'd like to have a metal hood over the top so the heat will be thrown outwards from the center of the stove.

Does anyone think that this will work? Same as the gas patio heaters you can buy. Except the rocket stove will have the flowing
air which I hope will blow outwards towards us sitting around it.......

It looks like you are wanting to exhaust into your occupied space? not recommended-CO kills. Perhaps that isn't what you mean. Have you studied the book?

No this will be outside in the yard. I want to put a plate on top to use as a BBQ. Then when finished cooking, put on some kind of heat deflector so the hot air blows out sideways where we will be sitting. Not going to use it inside.

Peter,

The radiant patio heaters are using a heat reflector, not deflector. Think optics. Gas radiant heaters attempt to convert as much of the heat released by combustion into radiant heat. This minimizes heat lost to convection and redirects it to the targeted zone. The reflective heat shield helps to reflect heat that is escaping upwards.

There was some discussion about radiant burners on the Stoves list last month. It stalled because of some false assumptions and unnecessary snittyness, but in the process some interesting patents were found that could be applied to a wood or biomass burning stove. This is one I think you might find interesting:

You could make some adjustments to the design to suit your application.
