If we can solve that with a vehicle that doesn’t throw away hardware (all recoverable) then we are good. But that engineering problem has proven remarkably difficult. I am thinking in the short term. next 30-50 years. It’s nukes and coal for baseload until we can get space-based solar going, if we ever do.<o:p></o:p></span></pre><pre><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></pre><pre><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>spike<o:p></o:p></span></pre></div></body></html>
