[Stoves] History of clean Chinese stove development. Re: Rights about stove designs Re: [biochar-stoves]

[Dean Still]

Hi Paul,

Here's a Chinese Tom Reed type forced air stove with primary and secondary
air.

Xunda makes great stoves and has been at the GACC forums, etc.

We have seen many Chinese batch fed natural draft and forced air stoves and
I think that Crispin and Ron have gone to stove expos in China?

The TLUD is a great idea and it reinforces how useful it is, if it was made
in lots of places.

 The insulated Rocket stove was already in Nepal and Tibet and hayboxes!

 I hope to hear from someone in China about the history of cooking stoves.

I went to a museum in Ningbo that had a big map on the wall showing the
2,000 year history of stove export by sea from China to India and Africa.

I wonder what kind of stoves were developed over such a long period of time?

Best,

Dean
