I have about 3000 miles on my smack. It is a direct copy of his design. I am using Reverse osmosis water and caustic soda (lye). The caustic soda is found at Lowes in the pluming section and it is used to clear drains. The bottle looks like this.
I have drained the water after 2400 miles and the water has a very slight yellow color. I have run the unit almost 1/2 empty and never took out the 30 amp fuse. I believe that Smack is telling the truth that the unit will not self destruct if built and used as he directs. As for the production I cannot duplicate what he said the unit should put out.
I will be changing the cell and attempt to get better performance.
