+  * http://www.tuks.nl/wiki/index.php/Main/TelluricElectricWaves  - An alternative to using sattelites may be to use waves trough the interior of the Earth, Tesla style.
+  * http://en.wikipedia.org/wiki/EME_%28communications%29 - Another alternative is to use a natural sattelite that is already there. Currently, an investigaton is being done to investigate the possibility of using longitudinal dielectric waves instead of the normally used transverse waves: http://www.energeticforum.com/renewable-energy/9727-who-performs-first-longitudinal-moon-bounce-history.html  First result is that the prototype antenna that has been made does resonate at a frequency it is not supposed to resonate according to current accepted (transverse EM) wave theory: http://www.energeticforum.com/173559-post104.html
