Eco-Friendly Engine Pioneers are Searching for New Sources of Clean, Green Power

In this article the author describes the use of more ecologically sustainable fuel sources as they apply to construction equipment. The highlighted devices include a hydraulically-based high-pressure transmission that, despite being in development for a decade, has only recently found interested parties in manufacturing. The article covers a number of the economic issues with decreases in fossil fuel consumption, particularly as companies are very reluctant to implement practices that will likely harm them financially. The government, however, has attempted to add incentives such as tax credits to ease such burdens. One device that has been developed towards such ends is a hybrid excavator that has recently begun to be tested in Japan. The excavator could boost fuel economy over conventional excavators by up to forty percent. The article also looks at other hybrid-drive vehicles and flexible-fuel engines. Included is a chart listing eight different alternate fuels and their related advantages and disadvantages
