The US currently has approximately 200 TCF of known conventional reserves (EIA, 2006a), with annual domestic production (2004) of approximately 19 TCF (EIA, 2006b). The US also has an enormous potential source of new natural gas reserves in unconventional reservoirs including tight gas sands, gas shales, ultradeep water reservoirs, and methane hydrates. In total such reserves could provide energy independence for the US if they could be economically produced. Tight gas sand reservoirs are estimated to contain 200-1000 TCF of reserves, depending on the technology available to find and produce them (RPSEA. 2005). These reserves, however, are produced through fractures (both natural and induced) and can only be brought on stream through improved technology for the remote sensing and characterization of these fractures. A brief overview of passive and active seismic methods used to image and characterize such fractures will be shown, along with some promising new methods based on scattered wave analysis. </DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><BR class="khtml-block-placeholder"></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><BR class="khtml-block-placeholder"></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><I>And next week: </I></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><BR class="khtml-block-placeholder"></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" color="#000000"><B>"Near Term Technologies for Improving Ethanol Use and Production:</B></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" color="#000000"><B>Ethanol Boosted Gasoline Engines and Plasma Waste Conversion"</B></FONT></DIV><BR><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><B>Daniel R.

Use of a small amount of directly injected ethanol in gasoline engines can enable high efficiency at low cost. Direct ethanol injection essentially removes the knock limit on engine power density thereby allowing the replacment of large engines with much smaller and more efficienct turbocharged engines which provide the same or better peformance. Plasma waste conversion can be used to produce ethanol and methanol from municipal and industrial waste. Waste material is an attractive feedstock because of its negative cost. Municipal and industrial waste in the United States could potentially provide a renewable source of more than 30 billion gallons of alcohol fuel per year.</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><BR class="khtml-block-placeholder"></DIV><P style="margin: 0.0px 0.0px 0.0px 0.0px"> </P><DIV style="text-align: justify;margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Bring your lunch - dessert will be provided.</DIV><DIV style="text-align: justify;margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="text-align: justify;margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="text-align: auto;margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">___________________________________________________</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">If you would like to be added or removed from this mailing list, please contact Karen Gibson, <A href="mailto:kgibson@mit.edu"><FONT class="Apple-style-span" color="#1B79FC">kgibson@mit.edu</FONT></A></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><BR></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Karen L.
