Dear Cory,
What worriedme is when I lost my business and everything I had even my health when I was ripped off. I have a rocket stove and oven that is a very special way to cancel out co2's and other harmful fumes that I ca't afford a patent on, but have shared it with permies and third world countries just about of what you said. 
I love your path by the way. Keep up the god work.

Ray, who cares if the Chinese rip it off? You would still sell some - maybe a lot of them. 

It is all one big Akashic record anyway, right?  

But unlike many who may have access to that idea (and someone in China could come up with this idea on their own certainly, if they came up with the underlying concept in the first place), you went out and built one, and could build more. And that would help a lot of people get things done that would get us more off the oil teat.  So what is the greatest good?  To get this idea you had out there and into broader use, or worry about someone ripping you off from an idea that should go world wide faster than one guy can manufacture them anyway - in order to help save Mother Earth?

I hope that you will consider going forward with manufacturing this, or at least doing an ebook to show others how. You can benefit economically from it, even if others "rip it off."  If you do nothing, what will happen?

The wheelbarrow is most definitely grossly inferior technology - a perfect example of someone coming up with something and nobody ever questioning the design elements from thence forth, to time immemorial.  Jeez!   Glad to hear someone is doing something about that sucky design finally.

I love the fact you've felt our wheelbarrow is not a multi-purpose tool. The reason it has one wheel is to go across a ditch on a board. When I was learning cob up in Coquille I saw the log hog and felt it was limited to what it could do as is the wheelbarrow. So I built a cobbers wheel barrel that does more than anything out there. It has two air filled wheels and can carry 500 lbs with one hand, beacuse of the perfect balance.It carries gravel,sand cob, logs, and I use it as a trailer for my bike. I love going to the beach and finding large redwood up in the Pacific NW. The cobberbarrow weighs about 40 lbs or less. I was going to start building it for sale, but knew that the Chinese would rip it off like they've done with so many things.I hope someday someone can make even a better cobberbarrow than mine. Just keep thinking..
