&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;With APM one can create valves that can open and close very fast.&lt;br /&gt;
&lt;br /&gt;
== Methods ==&lt;br /&gt;
&lt;br /&gt;
For maximal switching speed one can use interleaved shells that move into opposite directions (using [[infinitesimal bearings]]?) and have gaps that match up only at certain times. The timespan relation betwen open and closed states is heavily restricted.&lt;br /&gt;
&lt;br /&gt;
For lower but still high switching speeds platelets that when moved completely balance out linear and angular momentum can be used.&lt;br /&gt;
&lt;br /&gt;
== Applications ==&lt;br /&gt;
&lt;br /&gt;
One &amp;#039;&amp;#039;speculative&amp;#039;&amp;#039; application of such valves is [[nuclear fusion|inertial fusion]].&lt;br /&gt;
Where it could be used to let through an accelerated fuel pellet of hydrogen and close the &amp;quot;door&amp;quot; right behind to protect the acceleration area from radiation that is backscattered electrons protons and generated gamma rays (as far as possibel).&lt;/div&gt;</summary>
