Engineers believe it could be used to boost the performance of small gasoline engines.
Cars that weigh less can use smaller, more efficient gasoline engines that get better mileage.
Mechanical looms, steam- powered locomotives, gasoline engines, electric motors ? none had an instant effect on productivity.
But it's the big gasoline engines that fund their pensions and golf memberships.
But none of those attempts managed to improve substantially on existing gasoline engines.
The catch is that gasoline engines generate fewer harmful emissions than diesel engines.
In the United States, gasoline engines currently power more than 200 million cars.
Because diesel engines are more fuel-efficient than gasoline engines, the use of diesel fuel is expected to continue to expand.
As of mid-2013, here is where we are: Gasoline engines in cars aren't going away, but they are going to get smaller.
Diesel engines and the elaborate emissions control equipment they require in the United States are more expensive to build than gasoline engines.

Gasoline engines can be modified to run on methanol at modest cost.
FORBES: Governors Press Detroit To Make Natural Gas Vehicles
Maruti also has an engine facility in Gurgaon in which it makes its so-called K-series gasoline engines that power most of its vehicles.
Unlike hybrids, even newer diesels run afoul of emissions laws because they produce more particulate matter and smog-forming nitrous oxide than gasoline engines.
Ford, meanwhile, has stayed away from diesel and focused on hybrids and EVs as well as more fuel-efficient gasoline engines through its EcoBoost technology.

Automakers have also been looking for ways to expand diesel passenger vehicles sales in the U.S. because the engines are 30% more fuel-efficient than gasoline engines.
Honda, the world's eighth-biggest automaker, has developed a panoply of technologies: hybrids, fuel cells, clean diesels, natural gas vehicles and the world's most sophisticated mass-market gasoline engines.
But the new standards will likely require auto companies to develop more hybrids, plug-ins and natural gas vehicles, while using more lightweight materials and improving traditional gasoline engines.

It already manufactures 1.5-liter diesel and gasoline engines in India.
Hyundai had already suspended production of diesel engines at its Ulsan plant and warned earlier on Tuesday it could also have to stop production of petrol or gasoline engines.
This means that the limit to the compression ratio with gasoline powered engines is about 9.5 or 10:1.
Every year, China produces approximately 50 million gasoline and diesel engines for transportation.
Ford will likely introduce the EcoSport in India in June with 1.5-liter gasoline and diesel engines as well as the 1.0-liter engine.
Palladium, on the other hand, is used more in gasoline-powered engines that are popular in North America and China, and that is another factor underpinning palladium, Steel said.
FORBES: FOCUS: Platinum, Palladium Show Divergence; Reflects Fundamentals
That would only replace about 0.07 percent of the 140 billion gallons of gas Americans use each year, and that's assuming everyone switched from gasoline to diesel engines.
These engines use gasoline or diesel, and both fuels are full of chains of carbon atoms known as octane.
It actually began to occur long before humans invented agriculture, smoke stacks, and gasoline-fueled internal combustion engines.
FORBES: Gullible Warming: A Contrived Crisis That Is Too Good To Waste
In 2008, as a reporter at Forbes, I investigated the likely impact of rising ethanol blends in the U.S. gasoline supply on small-engines in boats and outdoor equipment.
Flex fuel engines can run on gasoline, E85(85% ethanol), or any combination in between.
Take a 20 kilometers-per-liter hybrid, which is a small car with two engines--one gasoline, one electric--that work in collaboration.
Ford Motor, for instance, is aiming to take as much as 750 pounds out of its future vehicles by 2020, which would enable the use of smaller, more efficient engines that burn less gasoline.
