Driving on Air


As concerns for the environmental continues to grow, many industries the world over have even working hard to develop products that are environment friendly, including the automobile industry.
From solar to hydrogen to electric, many innovative ways have bee employed to power vehicles with varying results. One such concept is the use of air as a fuel substitute.
Developed by India’s Tata Group, in collaboration with the French-based firm Moteur Development International, (MDI), the new technology is quite simple in its operation.
Unlike conventional engine cycles that depend on the combustion of hydrocarbon fuels, this engine that depends on the expansion of compressed air to move the pistons, resulting in a cleaner and quieter engine that expels nothing but very cold air without any traces of greenhouse gases. The compressed air used is stored in a carbon-fiber tank. Currently, two versions of this technology are on offer.
1-     Single energy compressed air plus fuel engines, which use only compresses air.
2-     Dual energy compressed air plus fuel engines, which may switch to fuel mode if the air runs out.
Two models of the air car are available; the MiniCAT which seats three people and the CityCAT, which has a capacity to seat six people.
In all other respects, both models are similar in that they can be bought either with the single compresses air or the dual energy version of the engine. Both versions can travel between 200 and 300 kilometers on one fill-up.
And when it cones to refilling, it takes about three minutes at a purpose built station.
The air is set to make its Unites States debut sometime this year.
