the finance of pellet machines throughout the world.<BR></DIV>

<DIV dir=ltr>In my previous email I concluded by saying:<BR><I>What's
needed above all else, in my opinion, are small, beautiful TLUD's that
make use of pellets. Such units could be situated in modern kitchens
throughout the world. Once these units are in place, the rest will
follow.</I><BR>
<DIV><BR>It seems that Home Depot, Wal-mart, Lowes, Ace, Agway and many
others large retailers in the USA all carry wood pellets. Why can we not
make TLUDs that make use of these pellets as fuel? The only thing that
changes is the height of the reactor: it's much less than the height of a
reactor that uses undensified biomass. This means that the TLUD is small,
lightweight, mobile and much cheaper.<BR><BR>Here is an example of what I
am talking about:<BR><A

target=_blank>https://dl.dropboxusercontent.com/u/22013094/150%20Gasifier/Short/DrawingsUltra/001.pdf</A><BR>The
total height of the reactor is less than 10 inches.<BR></DIV>
<DIV>This reactor holds about 2 kgs of pellets.<BR></DIV>
<DIV>This gives a burn time of about one and a half hours.<BR></DIV>
<DIV>The reactor itself in 304 stainless steel weighs less than 1.5
kgs.<BR></DIV>
<DIV><BR></DIV>
<DIV>We've already tested taller TLUDs on rice hull pellets,<BR></DIV>
<DIV> and they emit the same beautiful blue flame as when loose rice
hulls are used.<BR></DIV>
<DIV>Another big advantage of pellets is that there is much less
particulate matter emissions compared to loose rice hulls.<BR></DIV>
<DIV>Loose rice hulls are dusty, messy, bulky and a real nuisance to store
and load.<BR></DIV>
<DIV>In an urban setting it makes no sense to be hauling in loose rice
hulls of a bulk density of only 80 kg/m3.<BR></DIV>If we're going to
compete with fossil fuel gas, we've must reach a certain level of
convenience and ease of use.<BR>

<DIV>In may cases transport distances are short, and the economics are
quite good, and yet we complacently continue to burn fossil fuels. I
lived for over 20 years in West Flanders in Belgium where wheat fields
encroached upon densely populated rural areas, and yet everyone merrily
burned LPG gas to cook a meal. Later I move to Waxahachie, Texas, a
small town near Dallas, and once again, wheat fields were everywhere.
Yet no one dreamed of making wheat husk or wheat straw pellets and using
them to make syngas to cook a meal.<BR></DIV>

<DIV>China appears to be struggling with a lack of infrastructure in
getting pellets to market. How does one explain the economics of
shipping coffee husk pellets from Brazil to Holland as we see in this
link? <A href="http://www.coffeehabitat.com/2007/10/coffee-husks-as/"
target=_blank>http://www.coffeehabitat.com/2007/10/coffee-husks-as/</A>
This is a thoroughly bold undertaking, but does it make sense to
transport coffee husk pellets half way around the world to provide fuel
for Dutch power stations? Why not make use of these pellets in Brazil?
Also, one might argue that the highest and best use of coffee husk
pellets would be, not to burn them in huge power stations, but to
generate from them a syngas that would replace bottled gas or other
forms of fossil fuel gas. The biochar left over from these stoves would
then be returned to the soil.<BR></DIV>
