<div dir="ltr">I watched<span style="font-size:12pt;font-family:Arial,sans-serif"> Rein’s presentation (not the Q&A). He spent a fair amount of time talking about how plentiful and cheap deuterium is. Indeed you can get it from water by simple electrolysis. It could hardly be any cheaper. But he didn't talk about tritium, which is more complicated. If you wanted to buy it it costs ~$300,000/gram and has a 12 yr half life; probably the most expensive material </span><span style="font-family:Arial,sans-serif;font-size:16px">on earth </span><span style="font-size:12pt;font-family:Arial,sans-serif">bar none. (<a href="https://en.wikipedia.org/wiki/Tritium#:~:text=As%20of%202000%2C%20commercial%20demand,approximately%20US%2430%2C000%20per%20gram.">https://en.wikipedia.org/wiki/Tritium#:~:text=As%20of%202000%2C%20commercial%20demand,approximately%20US%2430%2C000%20per%20gram.</a> ) The cost is high because it is a byproduct of breeder reactors. HOWEVER for use for fusion it can be breed inside the reactor by bombardment of beryllium and lithium. Fortunity, there is a lot of research on this (MIT/CFS don't have to develop it.) It does mean you need to procure beryllium and lithium which is a more expensive process than procuring deuterium. Beryllium and lithium blankets for fusion reactors are discussed here starting about one-fourth of the way down: <a href="https://www.fusion.qst.go.jp/rokkasyo/en/project/blanket.html">https://www.fusion.qst.go.jp/rokkasyo/en/project/blanket.html</a></span><div><img src="cid:ii_l157o9uc1" alt="image.png" width="562" height="136"><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Mar 24, 2022 at 8:14 AM john rudy <<a href="mailto:jjrudy1@comcast.net">jjrudy1@comcast.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div lang="EN-US" style="overflow-wrap: break-word;"><div class="gmail-m_4952363874543508873WordSection1"><p class="MsoNormal"><span style="font-size:12pt;font-family:Arial,sans-serif">85 minutes<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Arial,sans-serif"><u></u> <u></u></span></p><div><p class="MsoNormal"><span style="font-size:10pt;font-family:Arial,sans-serif">John Rudy<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:Arial,sans-serif">781-861-0402<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:Arial,sans-serif">781-718-8334 (cell)<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:Arial,sans-serif"><a href="mailto:John.rudy@alum.mit.edu" target="_blank"><span style="color:rgb(5,99,193)">John.rudy@alum.mit.edu</span></a> <u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:Arial,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:Arial,sans-serif">13 Hawthorne Lane<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:Arial,sans-serif">Bedford, MA 01730-1047<u></u><u></u></span></p><p class="MsoNormal"><img border="0" width="99" height="94" style="width: 1.0312in; height: 0.9791in;" id="gmail-m_4952363874543508873Picture_x0020_2" src="cid:17fbc90318a4cff311"><span style="font-size:10pt;font-family:Arial,sans-serif"><u></u><u></u></span></p></div><p class="MsoNormal"><span style="font-size:12pt;font-family:Arial,sans-serif"><u></u> <u></u></span></p><div><div style="border-right:none;border-bottom:none;border-left:none;border-top:1pt solid rgb(225,225,225);padding:3pt 0in 0in"><p class="MsoNormal"><b>From:</b> Robert Primak <<a href="mailto:bobprimak@yahoo.com" target="_blank">bobprimak@yahoo.com</a>> <br><b>Sent:</b> Thursday, March 24, 2022 6:03 AM<br><b>To:</b> Lex Computer Group <<a href="mailto:lctg@lists.toku.us" target="_blank">lctg@lists.toku.us</a>>; john rudy <<a href="mailto:jjrudy1@comcast.net" target="_blank">jjrudy1@comcast.net</a>><br><b>Subject:</b> Re: [Lex Computer & Tech Group/LCTG] Fusion<u></u><u></u></p></div></div><p class="MsoNormal"><u></u> <u></u></p><div><div id="gmail-m_4952363874543508873ydpe1c52c90yiv9517024821"><div><div><div><p class="MsoNormal"><span style="font-size:10pt;font-family:Helvetica,sans-serif">We haven't had a session on fusion in awhile.
