A couple of things to note here...
He doesn't say whether or not his generator is warmed up for the first test. If not, then it will definitely use more gas on the first run which will skew his numbers. Since he is showing a notebook with 12 points of data though I suspect he has accounted for this.
1400 watts @ 5.88 LPM is only 4.2 MMW not his best cell. I hope he doesn't claim the DC amps for his calculation of MMW. It needs to be the wattage of the entire system. He does say that he is using two DC battery chargers to run the cell. Mucho energy loss there.
Other than that it is a great visual of what is needed to get better mileage on a vehicle.
Lets see... for my 3.0 Litre Saturn VUE...
3000 / 375 = 8 * 5.88 = 47 LPM (he corrects his video up from 5.6 to 5.88)
Seeing as how my best cell is only good up to about 7-8 LPM with my alternator, I don't see how this can be done without an external generator... and a bodatious one at that.
Again, I will continue to watch the technology and see where it goes. But for now, I don't see it working for my needs.
Great video!
