Let's address the real problem

Here's a great invention that addresses the real problem. Not the so called "global warming", but air pollution and smog in our cities.

The CAT is powered by a thermodynamic motor that runs on air that’s been compressed to 4,350 psi. When the air enters the engine it expands and exerts force on pistons, thus creating the power. When the driver presses the accelerator pedal, a valve opens which sends air to the engine. The CAT has a 52-gallon compressed air tank that powers either a 15 or 22 horsepower motor, enabling the car to reach a top speed of between 90 to 110 km/h (68 mph), and travel up to 200 km (125 miles).

It would be nice to see some of those on our highways. So far their only noticeable disadvantage is the relatively short travel range - 200km per fill-up. So even a trip from Moncton to Halifax would require stopping in the middle for refueling (repumping, to be precise).

However, the savings on fuel make it worthwhile. It only takes $2 worth of electricity to refill the compressed air tank, which is enough for 200km travel. Even if the gas stations start charging twice as much for compressed air, still that would only be 2 cent per kilometer, compared to at least 6.5 cents for the most fuel efficient cars (6 liters per 100km at $1.08 a liter). Cleaner air and cheaper travel - that's killing two birds with one stone. With absolutely no need for Kyoto and its carbon trading scam.
