What do you think?
These would be a good fit to match the claims of some people on the internet and this forum of being able to produce the EQUIVALENT ACTIVITY (MPG Results) of 2 to 3 liters of HHO in a non-stainless steel anode configuration inside PVC tubes.
The last photo shows some USED UP stars that have felt the effects of harsh chemicals. Before they are used up they are nice and pretty.
Platinum Anodes produce pure hydrogen not HHO. This may be the key to what we are looking for.
