Which is basically what they did; upthread, someone links to the specs and they have an onboard Cummins diesel generator.

Check the Features & Specs page [1]

    74-hp Cummins diesel QSF2.8
    4 hydraulic drive motors
    75-gallon fuel capacity

I'd bet that diesel also powers a generator to run the computers and 150W lasers.
