The most promising scenario is to build a cylindrical mesh of wires that can be attached to a spacecraft. The mesh can be charged up using a coating of a radioactive isotope that emits charged particles. Dr. Peck has proposed developing a 100 kilogram spacecraft that carries a wire mesh 82-meters in diameter</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/26AC3B48-5853-41A9-88E1-75E3CA0A1D56/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
