Good evening.
I too am fairly new to prospecting. I have been wanting to re visit Italian Bar, CA since I was there when in boy scouts. Not going to say what year but vividly remember the Echo satellite go overhead as our scoutmaster was telling a horror story about aliens. I think he was a little spooked that night as well.
Now to current issues. There are questions on what is "non motorized". Varied state to state and what kind of day the powers to be is having.
As I have read, here in California, motorized is a internal combustion engine or electrically driven motor. Human powered, and gravity fed is OK. Internal combustion includes both gas and diesel engines. However there is no mention to external combustion engines, IE steam boiler and steam engine. Not a back packable item. Also a windmill and non electric drive, I guess is legal, but again not back packable.
Now on the other hand, I have tested and am in second design of a bicycle powered water pump for high bankers that will deliver 1000 to 2000 GPH.
I ran the first prototype last weekend at a local treasure hunter BBQ and swap meet. There were many non believers who now believe. I will post videos soon. Also can easily change to put a generator in place of the water pump. I have been able to generate in excess of 20A at 14.2V for 20 to 30 min. I ran out of beer!
The generator is for my other hobby, ham radio.
And the bicycle is good exercise.
