Hi Cheryl. Great pic. Same one I started with 3 years ago. I would brew one pint for 40 minutes or so using this method (3-9 volt batteries). Very simple generator to get started with. It will produce about a 5 ppm batch of CS. It does work but dont expect anymore than 5 ppm and drink what you make daily, give the rest to your dogs, cats or chickens.
