<DIV class=moz-cite-prefix>Dear Paal,<BR><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><BR>Paul<BR><BR><PRE class=moz-signature cols="72">Doc / Dr TLUD / Prof. Paul S. Anderson, PhD

to 40 mm green sprouts from 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>

had an experiment at Nyabyeia Forest College in Uganda 15 years ago with a 75
hp. tractor with a wood chipper and two men with machete cutting pine twigs.
The two men could compete in price per bag, but not in quantity and they got
tired. A household need about 4-5 kg per day for cooking, and that will easy
be cut by somebody in the compound.</FONT></SPAN></P>
