Dear Scott,
I think that you can get your lab testing done for a decent cost
at Bruce Marx's page (I know it is the same person that produces the $600
AC machine and you did not enjoy his commercialism) but he does provide
for $100 the testing of ppm for four 1-2 oz. samples ($25 each) and the
same goes for particle size testing. Also, for each sample above a
total of four samples, the cost is $20 each.
Also, I am trying the householod current experiment. Even with
heating for one mintue and then running for 75 minutes I get a weak
Faraday-Tyndall effect. This has to be repeated over and over until a
definite tecnique can be found which won't unless, like I think Mike
said, we attach a voltage and current regulator.
I think I will also experiment with that adaptor you talked
about, and the good old 4 9 volts again.
All we can do is speculate because only God has all the answers.
