[All] Air powered mass transportation

[Robert Milligan]

Lulu,

Glad to see that you are interested in new propulsion systems for mass  
transit. MIDI's founder Guy Negre is the inventor/designer of one of a  
long line of compressed-air- propelled vehicles, http://www.aircaraccess.com/history.htm 
. While his english site that you referenced, http://www.mdi.lu/english/multiflowair.php 
, 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,  http://www.mdi.lu/. 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?).
