The combination of water and light from the sun can be used to produce hydrogen and oxygen. The hydrogen can then be combined with the oxygen in a fuel cell to give back water and energy. In the overall cycle, sunlight is converted to useful energy. But here is the catch. A response to this grand challenge of using water and sunlight to make a clean and sustainable fuel to power the planet demands the discovery of new materials and new reaction chemistries. This talk will present some of the basic science that is needed to emulate photosynthesis outside of the leaf, and then discovery will be presented that enables artificial photosynthesis to be realized. And this is just one approach that is ongoing at the frontier of solar research at <font class="Apple-style-span" color="#000000">MIT. A group of MIT faculty is committed to developing the science and engineering needed to enable solar energy to be implemented in under 10 years. The efforts of these groups will also be presented.</font></span></font></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 19px/normal Helvetica; "><font class="Apple-style-span" color="#000000"><font class="Apple-style-span" size="3"><span class="Apple-style-span" style="font-size: 12px;"><br></span></font></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 19px/normal Helvetica; "><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 18px/normal 'Myriad Pro Condensed'; "><font class="Apple-style-span" face="Helvetica" size="3"><span class="Apple-style-span" style="font-size: 12px;"><a href="http://web.mit.edu/chemistry/www/faculty/nocera.html">http://web.mit.edu/chemistry/www/faculty/nocera.html</a></span></font></div></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 19px/normal Helvetica; "><font class="Apple-style-span" size="3"><span class="Apple-style-span" style="font-size: 12px;"><br></span></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 19px/normal Helvetica; "><span class="Apple-style-span" style="font-size: 12px; ">Light refreshments will be served at 4.30 pm outside the lecture hall.</span></div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><font class="Apple-style-span" color="#000000"><br><br><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 16px/normal 'Myriad Pro Condensed'; "><font class="Apple-style-span" face="Helvetica" size="3"><span class="Apple-style-span" style="font-size: 12px;"><br></span></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 16px/normal 'Myriad Pro Condensed'; "><font class="Apple-style-span" color="#000000"><font class="Apple-style-span" face="Helvetica" size="3"><span class="Apple-style-span" style="font-size: 12px;">More info: <a href="mailto:sfowler@mit.edu">sfowler@mit.edu</a></span></font></font></div></font></div></div></div><br></div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "></div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><br></div></div></div></div></div></body></html>
