Drivers in the U.S. are buying hybrid vehicles, not because they want them, but because they can't afford to drive any other type of car. With gas prices setting all-time records and heading toward $4 per gallon, consumers are forced to drive a car that gets the most miles per dollar spent. That's an overpriced hybrid car.

The truth is that hybrids may get better mileage than a traditional car, but it's nothing to write home about. First, hybrids cost more. The slightly better mileage means that if you keep your hybrid car for from 3 to 5 years you may make up for the higher cost. That doesn't seem like such a good deal, does it? But it's all we have and that's why folks are buying the darn things.

The good news is that big improvements are on the way. AFS Trinity Power Corp. has been awarded a patent for a new flywheel technology that is expected to be used in second-generation flywheel/diesel hybrid trucks and buses.

This new flywheel within a flywheel technology is expected to make possible two key functions in both automobile and stationary power systems that utilize fuel cells and/or micro turbines. The problem is that these gadgets are constant power output devices, which means they can't speed up fast enough for acceptable acceleration and passing. The new flywheel gizmo may correct that.

Is this the huge breakthrough in automotive propulsion that we've been waiting for? Probably not, but it's an indication that a bunch of really smart people are working on the problem of developing a car that gets a million miles per gallon... or something like that.

President Bush recently signed a federal energy bill that encourages the use of fuel-efficient, low-emission vehicles and offers substantial tax breaks. The bill proclaims that high-efficiency vehicles, either hybrid or diesel, will receive credits on a sliding scale based on efficiency. Let me translate - "credits" mean MONEY! The maximum credit for light-duty vehicles is expected to be about $3,400.

When Uncle Sam starts handing out cash, two exciting things begin happening. Number One: Lobbyist begin shoveling it into their pockets. Number two: Lights go on in garages all across the country as inventors strive to solve the problem. You might say they are burning the midnight oil - one of the few fuels that is not necessarily in short supply.

Some point out that there is already a system to make biodiesel from vegetable oils for as little as 70 cents a gallon. This fuel does not contribute to global warming, has no obnoxious odor and is overall pollutant-free. Did you know that years ago Rudolf Diesel invented the diesel engine to run on peanut oil? Nutty, huh?

Another alternative mentioned from time to time is alcohol fuel, or ethanol. It is usually made from fermented corn; it blends as much as 85 percent alcohol and 15 percent gasoline and runs gasoline engines very nicely. Oh, it has a minor drawback, if you consider being highly explosive a drawback. That stuff could turn a Morris Mini into a rocket ship!

Yes, I hate the hybrids... of today, but I just can't wait to see what's coming tomorrow.
