wanna move some dirt?

Everyone knows about hybrid cars, but unless you are into heavy machinery, you probably haven't heard of the new hybrid Caterpillar D7E dozer. From next year we'll start seeing it on construction sites. A bit like a diesel-electric train, this Cat uses a diesel engine to generate electricity, which feeds electric drive and steering motors. It will be able to move 25 percent more material per gallon of fuel than the machine it replaces. Less fuel means less emissions, so this baby will help reduce the carbon impact of big construction projects.
