thanks Peter and Thomas, plenty for me to think about and research

Hi all
just getting started with thinking how a RMH might work in my design so apologies if questions are very basic
1) what is the difference between a rocket mass heater and rocket mass stove
2) Can you design a RMH so it cooks food as well as heating?
3) can you design one that heats water ( I read it can be dangerous as a pressurised system), if so, is it a case of finding alternate way to heat water?
4) The area I am heating is relatively small and well insulated (35 sq metres)- would a small modern stove work nearly as well? ( as easy to purchase off the shelf with a water heater)
5) Also, in a separate refurb in an urban area are RMH recommended (or are there planning issues? has anyone retrofitted a rmh into an old semi-detached house? ( there is no fire place). Does the final exhaust have to always go through the roof or can it go via outside wall?
Apologies for all the questions - all tips gratefully received

Hi I am looking for organic, labour efficient ways of managing weeds on a gravel courtyard in front of my house ( pictures attached). They grow out out of leaf fall from nearby trees. It is quite impressive to see soil forming from leave decay and the weeds growing - it is just in the wrong place! I don't want to spray them and it can be quite labour intensive to pull them all up  ( as the grassroots pull up the  gravel stones) and hard to keep the leaves from the stones. Just wondering if anyone has any interesting solutions?
all suggestions gratefully received.
