I'd like to see a diesel prime mover ~15-30 KWatt with plug and play auto-start, direct drive DC alt/generator with reverse electronic variable frequency drive(constant voltage and 60 Hertz output, input rpm (~1500-3600)) varies with loads.... 8 hr or 30 hr tank size. and 3 phase option
Modular power panel with plug in Main wire harness(50', 100',150' twist locks), i.e. take the panel to the loads, leave the noise at the edge of site....
Hot water output from exhaust/radiator cutout(think ground heat-sandpiles, shack heater) software control of electric clutched? Optional pto run air compressor and hydro pak optional, ag style 2000/1000 rpm actual pto for farmers and future options......option back up power software/panel/cordage for home or shop? eliminate prime movers on mortar grout mixers... just plug in the Hydro hose to Power pack/generator....away from mortar cement dust....and sand...
pallet skid/cube w/crane loops or trailer mounted.
Aaron, anything produced for class 8 trucks in volume is going to be the best bang for the dollar... the market is huge, # made are high, and there is competition.
