<br>
VERY interesting. The two men were cutting the twigs to be what
length? And want was the length (or other dimensions) from the
wood chipper machine. <br>
<br>
Depending on your answer, and if the twigs could be cut at double
the length and still be useful, that would give a great reduction
in human effort (not 50% because the twig still needs to be
handled, but only half the number of cuts). And the chipper
almost certainly could not have been adjusted to make the longer
twig-segments.<br>

energy forest activity in Africa, can easy be cut with a
machete at an angle about 45 ˚. They will split up and
dry fast in the sun, ready to be used for cooking in a
TLUD within two days. 1000 trees can be planted at one
ha, and will give about 10 kg yield each every year. The
leaves should be left at the field. 360 trees around 1
ha land will give about 3600 kg, plenty of fuel for a
household and even some for sale. Into a good TLUD this
type of fuel will give about 20% biochar, which can go
back to the energy forest or soil.</font></span></p>

household need about 4-5 kg per day for cooking, and
that will easy be cut by somebody in the compound.</font></span></p>
