David Seigler and Fredrick Wood and of Future Energy Concepts have converted a pick-up truck to run on nothing but water. More from Youtube User PESNetwork:
[Here is] a video tour of the pickup truck that they claim to have converted to run on nothing but hydroxy gas, electrolyzed on-board, and on-demand, via a super-efficient electrolysis (from water) method they have developed. Their system allegedly produces 55 liters per minute on 55 amps. They also say the truck recently completed a road trip of more than 3000 miles, running on this set-up.
It's an amateur video but interesting to watch and quite funny in parts. With more than 37,000 views, it seems to have gone viral! It's also interesting to look at some of the comments below the videos; there are both supporters and naysayers. Watch video to the right.
