Hi everybody. Well, i guess this is a question d'or Peter. But anybody can reply. Do you think it could be possible to make a three sided insert batch rocket? Something like this With the back of the firebox having a p channel and a port at the apropriate height. The heat riser behind. Ans mass above ans bellow/around! I wonder if it could burn efficiently. Opening the glass would in turn, open a bypass direct to the chimney, above the fire.

You mean the firebox sides and door being flat 'glass' panels but everything else proper batchrocket?

Heat retention in the batchbox it's self would be lower... Perhaps having the bottom third cast from insulating refractory would keep heat for efficient gassification of the coal bed, and good secondary air preheat like in a standard batch box?
It is an interesting idea for sure... Oh to have enough clear neoceram, or robax to try that one!

The Holy grail of rmh - a fire you can watch. Efficient AND beautiful. But where's the mass? Eye level and up?

Something like that would add whole new dimension to owning a rocket stove and generate a huge amount of attention towards rocket stoves in general!
I guess all the glass could be double glazed and the fire could be multi functional... ie ... be able to slow burn a log for aesthetics once the room is warm?

I think most of the glass would be black from soot.
I think that fire is in the picture in burning natural gas with fake logs...?

Ok, valuable reality check. A RMH will never look like a gas fire insert. But if you had to try to make it work, what would you change? (Other than removing all the glass) Less glass, insulate the top and bottom, add a door so that the damn thing can be opened for feeding, etc.

Thanks docbb, great views.
I wonder where the limit would be for "more glass" vs "less frame" ...

Thanks docbb. Nice one.
Drooster, i understand two things, fire containement, to keep the fire hot. And i have seen several experiments where it didn't matter that much. What realy matter, is an insulated v shaped bed. Where the embers can burn more or less completely. And flame front. Which means, for a good burn, there should always be some flames entering the port.
I know that an insulated firebox works better, to some extent. But it can also mean verry fast offgasing of the wood. And overloading.
Son using glass for the firebox sides doesn't sound that crazy.
The real difference, in this idea, would be a bed of logs oriented paralel to the firebox back. And this could prove interesting. As flames would have to travel less to the port, from the ends of the wood. Than in a long firebox.
