[Stoves] [biochar] Julien Winter: a soil scientist in name but not in practice.

Dear Andrew

 

All that is helpful. I will take a look closer to the time there is time :)
.

 

We are building the YDD Lab about which no doubt you will be hearing more in
the months to come. The gasifier is in the YDD workshop so we see it every
day but there is a lot of parts to make and assemble.

 

>We had this discussion in the late 90s before biochar emerged as a use for
small sizes of charcoal.

 

What Herbert says is that the process is very simple and it works.

 

>I remember discussing the Kalle gasifier, this was a WW2 device that was
basically a tin can with a central inlet which could be agitated 11RC. 

 

I will get pictures and think about the uses.

 

>The resulting producer gas was chiefly CO and Nitrogen. As it largely
lacked the hydrogen of woodgas flame speeds and calorific  value were lower,
substantially reducing engine power and speed.

 

That will be a consideration, but being independent of carting fuel from
another island is a huge advantage. 

 

>Whilst it would be naturally cleaner of tars than woodgas I suspect it
would still need more oil changes and maintenance than refined diesel.

 

I will ask.

 

Regards

Crispin
