Motor Company Plans To Launch Car Engines That Run On Air

say what

ooooooooooooooh that explains it Tata is behind this  ::rofl::

T his makes sense , the only  problem that I can see is whether the compressor would be operated with coal or petroleum generated electricity. If the air can be compressed with solar panels electricity , then it is a pollution free cheap means of transport.
Research like this would never be permitted in the west because the petroleum lobby is too powerful.
Diesels  engines can be cheaply converted to run on coconut or  vegitable oils  but this is not encouraged , that powerful oil lobby again .

well that makes sense they (combined) do generate a lot of "hot air"

  compressed air engines has been around for a long time , the only problem is its efficency .  There are two  types of these engines , the linear type  where air is pumped on to a finned flywheel device that causes rotary motion  The other type is where is when compressed air probably heated ,  is  forced  on to pistons in a chamber  resulting in reciprocating or up and down motion as in the internal combustion  engine that is available today.
Power tools and  even.  your leaf blower converts compressed air into rotary motion.
Great for TATA  a dynamic company , maker of the Nano

ah think kwami getting smarter with age. 

Your lack of knowelege on motor vechicle engines is surprising , A purely electric  vehicle like say a golf cart or forklift converts the  rotary motion of the electric motor into mechanical energy and in  a compressed  air car , the electric motor would be substituted with a compressor.
T he compression ignition engine of  Induction ,Compression , Power and Exhaust would be made obsolete by TATA.
