In a farm/preserve/etc scenario with a big diesel tank for the implements, a large diesel genset to recharge the EVs might be workable and leverage that infrastructure. Fleets of these could probably be charged off a fixed genset (not datacenter scale, but up there), which might be useful in remote scenarios or where it is tough to deliver a lot of mains electricity. I don’t know how emissions would work out (is a genset better than multiple portable engines?) and it’d be obviously less efficient than just doing the combustion in the vehicles, but it is something that came to mind when you mentioned that which might be useful for this type of vehicle.
Even if it’s a little worse in terms of the math, electric utility vehicles are strongly appealing due to their torque characteristics and fewer parts which always seem to be the ones you forgot spares of and such. With passenger sedans you’re playing the efficiency game, but with off-road, utility, industrial, and so on, there is more to think about when considering EV. Might not be that weird. (I’m a Wrangler owner who reads about electric conversions constantly — look at South Korean work on Jeeps — and I completely get where Bollinger is coming from.)
