"If the promises of competitive, large-scale cellulosic ethanol production are realized, and if nationalist import/export policies for biofuels are further liberalized, then the possibilities for ethanol to replace 20% of gasoline consumption in the U.S., China and India may be realized by the year 2020."

-- William Thurmond, author of Ethanol 2020: A Global Market Survey

Who is Thurmond to think he knows how biofuels will replace oil????

<p>I do not see skepticism in Swenson's response.&nbsp; I see knee-jerking reaction, as is becoming all too typical of anti-biofuels backlashers.&nbsp; This is evidenced by the apparent incapacity to make distinctions between the different generations of biofuels.&nbsp;It's all &quot;madness.&quot;&nbsp;If you look in on the work of the David Tillman group at University of Minnesota, you will see a potential for restoring mixed species prairie perennial grass ecosystems that actually accumulate more carbon in the soil than is released in the entire biofuels lifecycle, so the group calls these carbon-negative biofuels.&nbsp; In addition to soil restoration, they grow in droughty areas and on degraded soils, so they are just what we are going to need in areas where grain production is becoming impractical due to soil depletion and climate change.&nbsp; </p><p>In a more immediate prospect, many wheat farmers find oilseeds such as canola a great rotation crop that rebuilds soil fertilility.&nbsp; Potato farmers find a mustard rotation a way to naturally fumigate the soil and reduce the use of chemical soil fumigants.&nbsp; If we make biofuels markets for these oilseed crops, more farmers will be able to economically plant them and so the cultivation of major crops will become more sustainable.&nbsp; There are many examples like this where creating biofuels markets leads to improved environmental and economic sustainability for agriculture.</p><p>And let's&nbsp;not forget&nbsp;what we're replacing, petroleum.&nbsp; From listening to the knee-jerkers,&nbsp;it seems that they&nbsp;would prefer to continue using petroleum fuels, despite the fact that climate change will cause billions to suffer water stress and millions to die of famines.&nbsp;&nbsp;Of course we need much more efficient cars, more intelligently designed communities and other fuels such as electricity.&nbsp; And sure, we need to be aware of land use changes that release greenhouse gases, such as removing rainforests to grow palm.&nbsp; But overall, biofuels are superior to petroleum fuels.&nbsp; Let's keep that in perspective.</p><p>&nbsp;</p><p>&nbsp;</p>

<p>Ron is right and skepticism&nbsp;is quite&nbsp;different from&nbsp;pessimism, just as ignorance is not&nbsp;necessarily a sign of low intelligence. Brazil's energy independence is <a href="http://i-r-squared.blogspot.com/2006/06/lessons-from-brazil.html" target="_blank">not a result of&nbsp;ethanol</a>.&nbsp;</p><p><em>Were the tariff on Brazilian ethanol lifted, both E85 and pure ethanol prices would drop dramatically.</em></p><p>while simultaneously&nbsp;the clearing of Brazilian carbon sinks and biodiversity loss would increase dramatically. Cane is far more efficient than even cellulosic.</p>

<p>TOUCHE!</p><p>&nbsp;The 'Ferment' inthe biofuels research field is phenominal and global in nature.</p><p>&nbsp;Brazil is already independent of fossil fuels for vehicles; why not China or other countries that are heavy importers.</p><p>&nbsp;Were the tariff on Brazilian ethanol lifted, both E85 and pure ethanol prices would drop dramatically.</p><p>&nbsp;Last week, someone offered me spores of a fungus which broke down cellulosic walls and lignan to 'try out'...leading me to believe there is a lot more 'out there' we simply don't know about.</p>

The pessimist sees difficulty in every opportunity. The optimist sees opportunity in every difficulty.<br /><div align="right"><font face="verdana">--- <em><a href="http://www.houseofquotes.com/authors/Winston_Churchill.htm" target="_blank">Winston Churchill</a></em></font></div>

<p>2G, 3G, 4G.&nbsp; It all adds up to one thing: trashing the planet's remaining biological treasures cloaked in the rhetoric of saving the environment. Here's one more article full of superlatives without any grounding in hard facts. When data is given, will we see anything but the usual claims based on prodigious amounts of unobtainium, without compromise of soil and water resources? How can we stop this madness?&nbsp; </p><p>See &lt;A href=&quot;http://www.ecotopia.com/ases/SolarToday/BiofuelsScienceOrFiction.pdf&quot;&gt;Biofuels: Science or Fiction&lt;/A&gt;?</p><p>&nbsp;</p>

To M. Lee - My specific reference was to carbon-negative, meaning&nbsp; that&nbsp; the overall lifecycle&nbsp; of&nbsp; crop production and product use&nbsp; removes more carbon from the atmosphere than it&nbsp; emits.&nbsp; The&nbsp; phrase was used in the&nbsp; Science article on the topic, so peer-reviewed and subject to scientific rigor - <span style="font-size: 12pt; font-family: 'Times New Roman'">David Tilman; Hill, Jason and Lehman, Clarence, &ldquo;Carbon-Negative Biofuels from Low-Input High-Diversity Grassland Biomass,&rdquo; Science, Dec. 8, 2006, Vol. 315, p 1598-1600</span>

I have a difficult time understanding the difference between &quot;Carbon Free&quot; and &quot;Carbon Neutral&quot;.&nbsp; Makes me think that some environmentalists are better are learning buzz phrases than actually understanding the underlying science and technology of energy production and use.

<p>The conversion of materials into biofuels which are at present wasted&nbsp; has to be a good thing but even here one must be cautious.&nbsp;&nbsp; The use of corn stover, for instance, would appear to be an excellent idea but must be weighed against the positive effect of leaving the stover in the field to rot and improve the soil.&nbsp;&nbsp; The negative effect of not leaving the stover in the field will only be apparent after a good few years by which time the soil will have lost much of its humus and with it its production capacity.</p><p>The Conversion of waste paper, garden clippings sewage and compostables into biofuel, rather than sending it to a&nbsp; land fill or in the case of sewage, into the sea, would seem to be a good thing but perhaps there is an even better alternative.&nbsp; If all this material was composted and put back on the soil, great gains in fertility would be achieved.&nbsp; One could argue that the only reason that China still supports such a large population after some 5 to 8000 years of continual occupation is because they return almost everything back to the soil.</p><p>What is really frightening is the thought that the remaining jungles may be cleared to produce crops for the production of biofuel.&nbsp;</p><p>&nbsp; </p><p>&nbsp;</p>
