A buddy and I have been researching this topic for almost a year now. We built torches that melt everything from aluminum (yeah its not a tough metal) to stainless steel (316 gauge).
We failed with over many of our cells due to over heating, our new idea comes from the pdf link below, 6 cells in series to lower the voltage across the cells, aka less heat. We also have O2 modifiers to control the A/F. when we complete the construction and installation of the cells, i will post results.
A for record right now: I have a 95 geo prizm 1.6L
interstate (65-70mph) max mpg is 39. (this mpg is rather high as this the mileage i obtained on a 356 mile trip and drove through the mountains in Tennessee and coasted as much as possible)
state hwy (55mph) max mpg is 35
city (varies mph) max mpg 32.5
combined 34 mpg.
I will base my results on the maximum mileage I have obtained. I am an efficient coaster while i drive and am light on the pedals more so than ever. I will only consider this project success if I exceed these maximums.
Considering the majority of my driving is on a state hwy 100 miles per day 5 days a week, the state hwy will be the first results posted.
