I love the concept, but that would be my main reservation. We live at about the half way mark on a fairly significant hill with lots of snow and ice in the winter.
Electric Cars, Hybrids, Bio-Diesel, Air-cars etc... I hope people keep support the innovators of these technologies so they are no longer the best alternative, but just simply the best.
I currently run 20% Bio-diesel in my truck most of the time. I know folks in town with a bio-still, but I’m a little nervous to run pure bio-diesel in an 96’ with 200k on it.
