MIDI's founder Guy Negre is the inventor/designer of one of a long line of compressed-air- propelled vehicles, http://<a href="http://www.aircaraccess.com/history.htm">www.aircaraccess.com/history.htm</a>. While his english site that you referenced, <a href="http://www.mdi.lu/english/multiflowair.php">http://www.mdi.lu/english/multiflowair.php</a>, has a design for a little linked-bus, he also had a design for an little LRT when I first explored his work around 2 years ago. I see from his french site, that he has finally built a working version of his car, <a href="http://www.mdi.lu/">http://www.mdi.lu/</a>. Mass production of his compressed-air-only vehicles is likely still a ways off although compressed air propulsion can be part of a air/gasoline hybrid such as Ford is building (see last section in my 1st ref above). Compressed-air propelled vehicles were very early on used in mines and currently in small plane-towing vehicles on aircraft carriers -- both for safety reasons. Possibly they could be practically adapted for LRT's to capture braking energy then use it to assist acceleration (thus avoiding the possible emf field exposure of the new generation batteries &/or ultra-capacitors). The same applies to buses, etc. In this type of augmentary-use, you have close to zero worry about an explosion because a full high-pressure tank being breached. Apparently Guy was working with the Air Bus company to develop a carbon-fibre tank (lighter but safer?).</div><div><br></div><div>Robert</div><div><br><div><div>On 12-Jul-10, at 8:54 PM, Louisette Lanteigne wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><table cellspacing="0" cellpadding="0" border="0" style="position: static; z-index: auto; "><tbody><tr><td valign="top" style="font: inherit;">Mass transportation that runs on air.
