Compressed-Air is key to Renewable Energy and Independence

      Compressed air can be proven to retain 45% of the heat generated by the work of compression after the compressed air cools to ambient temperature. (See excerpt from Compressed Air, by Simmons hyperlinked below).
      This attribute of compressed air cannot be utilized with electricity.  The heat of generation (of electricity) cannot be captured and stored in electricity, that heat is simply lost by radiation into the atmosphere, a very wasteful and useless squandering of usable energy.
    Nikola Tesla said: "Steamers and trains are still being propelled by the direct application of steam power to shafts or axles. A much greater percentage of the heat energy of the fuel could be transformed in motive energy by using, in place of the adopted marine engines and locomotives, dynamos driven by specialty designed high-pressure steam or gas engines, by utilizing the electricity generated for the propulsion. A gain of 50 to 100 percent, in the effective energy derived from the fuel could be secured in this manner. It is difficult to understand why a fact so plain and obvious is not receiving more attention from engineers."

      A hybrid compressed-air-electric configuration would bring the best of the attributes of compressed-air work/power and electrical work/power together into a combination that would surpass the wildest conjectures of those attempting to create energy supply systems with the two forms of energy separately.
       A compressed-air-electric hybrid system would work the same way that "diesel-electric" hybrid power supply systems are used to provide the motive force for diesel-electric locomotives presently in general use.  
       Any compressible medium should NOT be used to provide torque horsepower to drive shafts that are mounted on wheels or used to power other rotating equipment.  Electric motor power is much more efficient. 
       This truth is readily discernible when observing the amount of power and tremendous torque applied to the drive wheels of locomotives to move vast tonnages of freight by the diesel-electric hybrid configuration.  A compressed gas (AIR) is what actually drives the pistons in a diesel engine, which in turn, rotates an electricity generator rotor shaft to generate electricity which is then used to power traction motors connected to the locomotive drive wheels through a speed reduction transmission.   Electricity cannot be "compressed" and is therefore much better suited to provide the torque required to rotate the locomotives wheels against huge weighted load resistance.
       The "air-car" enthusiasts are going about it in a way that is doomed to failure, or disappointment, at the least. 
       "Compressed-Air-Electric" HYBRID is the configuration to develop.  Compressed-air powering an air-driven generator to produce the electricity for high-torque applications.
