[Stoves] Jatropha and its future

Fri Aug 19 10:08:08 CDT 2011

Balkrishna,

Soapnuts are also known as 'Reetha' in Hindi.  You may know this name 
better. You may know them as something you might have used for hair 
washing as well as washing woollens.

   The /Sapindus Mukorossi/ tree is native to China and is related to 
Lychee. http://en.wikipedia.org/wiki/Sapindus
  They may actually be considered an alien plant by some Indian 
botanists [?], although they are grown extensively in northern India -- 
as well as southern China. They are also known as "Chinese Soap 
Berries", although Wikipedia says that "/The generic name is derived 
from the Latin words saponis, meaning "soap," and indicus, meaning "of 
India."/..." or "soap of the Indies".

Soap Nuts are actually not nuts at all. They are berries (hence the name 
'Soap Berries').
  They are also propagated in Indonesia and Japan (they may or may not 
be able to sustain freezing temperatures, depending on their specific 
biome).

  It is likely that early trade routes and nomadic tribes carried them 
by either man or animals from their origins in China to the other 
connected lands within Asia to the border of the Himalayas from South 
Eastern China to Nepal, and *North Western India*. It otherwise probably 
would have took about thousand of years to migrate down though Nepal to 
Northern India.

  They are also being grown in North America in places line Florida 
(this is the "Florida Soapberry" sub species: 
http://edis.ifas.ufl.edu/st582), South Carolina, Texas, Arkansas [they 
can be found scattered along limestone bluffs in the Ozarks], Oklahoma, 
Louisiana, Missouri, Arizona, northern Mexico and the Caribbean (often 
originally planted by Indian immigrants). There is a native North 
American Species, the "Western Soapberry" (/Sapindus drummondii/), which 
is a small deciduous tree about 30 feet tall belonging to the same 
soapberry family.
  They are also grown in Hawaii -- the Hawaiians use the hard, black 
seeds as part of their hula costumes... and for leis. (the Hawaiian 
species of Soapberry native to Oahu and Kauai, /Sapindus oahuensis/ ~ 
called 'aulu', 'kaulu' or 'lonomea' on the island).
   They may even grow them in some parts of Germany, Switzerland and France.

   In Asia there are two main varieties of Soap Nuts: /*sapindus 
trifoliatus*/ (The Small Soap Nut - ~ 1.4 grams, ~23-24% saponins, grows 
~12 meters high) and /*sapindus mukorossi*/ (The Large Soap Nut - ~2.8 
grams,  ~11-11.5% saponins, grows ~20 meters high). The Sapindus trees 
are extremely slow growing and take approximately 10 years before 
fruiting and providing berries.
  The Large Soap Nut is the most commonly used in cleaning (probably due 
to its size & ease of harvesting), but both varieties are quite 
effective. The weight of the seeds** are about 50% of the whole nut 
(including shell).

**Note that soap berry, like a cherry (Lychee or Longan 
<http://en.wikipedia.org/wiki/Longan>), has a big, black, rock hard seed 
in every fruit. The seeds should be removed when fresh off the tree 
before being used since the seeds have no value for cleaning (only the 
dried skin and pulp are used for that).
  (The seed ends up being only added weight if sold 'seed-in', so most 
people prefer to purchase soapnuts without the seed.)

   If you look around (contact the soapnut producers), you may find that 
there are small 'mountains' of Soapnut seeds that are sitting in piles 
and have no use. (The seeds of sapindus mukorossi are usually round, but 
sometimes pear-shaped: around 1/2 cm to 1 cm long / wide at the widest 
part.)

   I also suspect that the used, re-dried pulp might make for a good fuel.
  When dried it is quite hard and I believe that it retains its shape 
quite well.
