The smallest sail that could compete today with diesel power for commercial shipping would be a kite with a wing span over 30 ft.</P> <P>2. One critical technology for transport sail craft is electronic flight control.</P> <P>3. Much larger kites may bring the cost per horsepower hour down from around $.10 to $.01.</P> <P>4. Launch and retrieval present the greatest technical challenge.</P> <P>5. As oil prices rise in the 21st Century, the case for transport sail craft becomes much stronger.</P> <P>6. Thanks to major development in the last decade in recreational traction kites and UAV's, wind assisted commercial shipping will soon be viable. </P> <P><A HREF="military.html">Previous Chapter | </A><A HREF="Trans_Sailcraft.html">Back to Contents</A><A HREF="bios.html">| Biorgaphies</A></P> </BODY> </HTML>
