<DIV><FONT size=2 face=Corbel>Dear Anand,</FONT></DIV>
<DIV><FONT size=2 face=Corbel>Are you saying you have an AD system that produces
Biogas which does not require the expenditure of any energy?</FONT></DIV>
<DIV><FONT size=2 face=Corbel>Alcohol can be burned in diesel and gas engines at
100 proof replacing $3.00++ automotive fuel. I do not understand</FONT></DIV>
<DIV><FONT size=2 face=Corbel>your point about "<FONT size=3
face="Times New Roman">use the fuel where it is generated" but one of alcohol's
good points is it can be transported</FONT></FONT></DIV>
<DIV>inexpensively or used "where it is generated". With the advent of vacuum
operated alcohol distillation systems</DIV>
<DIV>direct sun light is all the external heat that is needed to produce
alcohol at 190 proof.</DIV>
<DIV><FONT size=2 face=Corbel></FONT> </DIV>
<DIV><FONT size=2 face=Corbel>We do not know if the honey facility can even use
biogas <FONT size=3 face="Times New Roman">"as it is", </FONT> or has
a need for it. Our natural gas boilers cannot use raw biogas</FONT></DIV>
<DIV>"as it is", we must scrub out all H2S to prevent damaging another boiler
and or most of the CO2 to avoid spending </DIV>
<DIV>thousands to modify the burners to burn both natural gas and biogas. I do
not know where or how you use biogas </DIV>
<DIV>"as it is" we tried it in unit heaters in our livestock buildings and
destroyed them in a year. </DIV>
<DIV><FONT size=2 face=Corbel></FONT> </DIV>
<DIV><FONT size=2 face=Corbel>The fact is in the last 45 years, we have found
almost no application for the long term use of biogas ,that H2S is not a
factor.</FONT></DIV>
<DIV><FONT size=2 face=Corbel>Cooking stoves, lighting, boilers, unite heaters,
water heaters, inferred heaters all experienced significantly shorter lives from
using </FONT></DIV>
<DIV><FONT size=2 face=Corbel>biogas <FONT size=3 face="Times New Roman">"as it
is". Some of the failures were out right dangerous. </FONT></FONT></DIV>
<DIV><FONT size=2 face=Corbel><FONT size=3
face="Times New Roman"></FONT></FONT> </DIV>
<DIV><FONT size=2 face=Corbel><FONT size=3 face="Times New Roman">Anand, I
believe you are being misleading to the point of being
untruthful. This could result in someone being hurt or
killed,</FONT></FONT></DIV>
<DIV>who might take what you said "Biogas can be burned as it is" as fact
and use it with out precautions.</DIV>
<DIV>Standard residential plumbing and appliances contain metals that do
not stand up under long term exposure to H2S. Especially in high heat
high</DIV>
<DIV>humidity conditions. Steel plumbing is used in most places that were
setup to use natural gas or propane. To suggest you can just pump</DIV>
<DIV>biogas"as it is" in place of other fuels is just wrong on many levels.
We are strong proponents of AD but the "Bad Press" the list is </DIV>
<DIV>currently discussing could be warranted in some instances. AD is not the
"highest and best" technology for all applications.</DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Corbel>Highest and best use principles require the use of
an energy audit and some study to determine which system is best
suited to each situation. My father, grand father </FONT></DIV>
<DIV><FONT size=2 face=Corbel>and </FONT><FONT size=2 face=Corbel>my uncles
refused to believe that the effluent from the AD system was better for the crops
than the runoff from the livestock buildings. It was only after the
areas</FONT></DIV>
<DIV><FONT size=2 face=Corbel>around the farms began to build up with new homes
and the complaints of smell threatened to shut us down that they allowed me to
build our first AD system. They then </FONT></DIV>
<DIV><FONT size=2 face=Corbel>could see an increase in crop yields in later
years, (and the smell went away). </FONT><FONT size=2 face=Corbel>I know corn
farmers </FONT><FONT size=2 face=Corbel>that use corn in there pellet stoves as
fuel to heat there house because fuel pellets cost more to buy than they
were paid for their corn. </FONT></DIV>

<DIV>Dear Brent,</DIV>
<DIV>for alcohol to be useful as fuel, it has to be distilled, which again
requires expenditure of energy. Biogas can be burned as it is. So, if you want
to use the fuel where it is generated, biogas is more advantageous than
alcohol.</DIV>
<DIV>Yours</DIV>
