<p>[QUOTE=&quot;-jeffB, post: 8298831, member: 27832&quot;]One problem for space applications is that it <i>is</i> so dense, which translates to heavy, which translates to expensive. Launching a kilo of platinum to geosync orbit would cost just about as much as the metal itself. But if that one kilo of platinum can do a job that would take two or three kilos of (say) aluminum, <i>it&#039;s cheaper</i>, because of fuel savings. I&#039;m just not sure what that application would be.[/QUOTE]</p><p><br /></p>
