Producing energy on Mars

There is an article in Popular Science on page 46 about using man made tornadoes to create energy. We all know that Mars is known for it's vivascious storms. Is it possible to use this type of machine to create an energy source on Mars? Could this machine also be used to stimulate the atmosphere to re-build itself by using the polar ice caps as a source for the hot water?

IIRC the atmosphere needs more than matter to rebuild itself, it needs magnetic shielding from the solar wind.&nbsp;<br /> <div class="Discussion_UserSignature"> </div>

The&nbsp;power produced by a windmill (or more strictly a wind turbine, since I doubt you will be wanting to mill grain<img src="http://sitelife.space.com/ver1.0/content/scripts/tinymce/plugins/emotions/images/smiley-laughing.gif" border="0" alt="Laughing" title="Laughing" />) is proportional to the density of the air/atmosphere, and the cube of wind velocity.&nbsp; Since the atmospheric pressure on Mars is only about about 8 milliBar (compared to 1 Bar on earth), for a given wind speed a wind turbine on Mars would produce less than a hundredth of the power it would produce on Earth. <div class="Discussion_UserSignature"> </div>

If what you say is correct, then a vane would have to be 4x as heavy to be used on Mars in comparission to the wind vaned used here on Earth. I can see it now, an Earth made vane would simply bend in different angles until it came off of the shaft and spun away at mach 1.<br /></p>
