Re: 2008 Escape Modifications?
WVO can be made by almost anyone, but even with small generators, they are strict on fuel types. WVO cannot be used in newer diesel engines for emission purposes, and even small engines are starting to get hit with emission regs. WVO is god if you can find an older gen set, but if the unit weighed say 400lbs installed in back, not to mention fuel, tank, piping, etc, I can't see it being integrated to use with the OEM battery without causing disastrous effects to the PCM and electronic system.
The PCM ultimately controls when to turn the engine on and when to shut it off. The engine comes on when the battery reaches a predetermined level of use. From what I've read the batteries never drop below 60% capacity, mostly to increase life. Once the battery gets up to 90-95% nominal charge, and you're say coasting, the engine should shut off until the battery drops down again.
I'm sure if you called around some specialty shops might be able to 'hack' into the PCM programming and alter some of the stock calibrations, but ultimately Ford designed the vehicle the way it is to not only last as long as possible, but to perform decent as well. Especially in an ever growing power-hungry society it makes sense to keep the battery more than half charged all the time.
Back to the generator; if you have a 2wd, I'm sure you'd be able to rig up a secondary power source to power the rear wheels independently of each other, but that can also cause any form of stability control to shut down power to the front drive wheels.
Not to say it's not possible to change the vehicle parameters, but it'll be very hard to do it safely, while trying to be more eco friendly at the same time.
If anything, I think Ford should have offered a diesel engine from the start, instead of the 4cyl gas variants. Or, a smaller displacement 4cyl with a slightly higher capacity battery which would have kept base curb weight the same with the current model. A 1.8L I4 won't charge the batteries as fast, however in North America people are more power hungry which comes at a cost, even for hybrids.
