[Terrapreta] Niels Bech's flash pyrolysis

[Robert Klein]

I dug up the abstract and I see that the idea is to
flash pyrolyse in the field by grinding the straw as
feed and harvesting the oil from the pyrolysis
process.

That means that a one ton bale of straw will be fed
into one end and produced oil and waste will come out
the other end.  I think that this is a difficult trick
to  practically pull off.  Straw is hard(high
silica)and will be hard on any machinery.

However, stuffing it into a shipping container and
making 400 degree bio char is very viable.  It is also
possible that the oil can be also salvaged in this
sort of setup if the heat is increased and the gases
perhaps separated.

Sometimes we try to be tooo efficient.
