Make it inexpensive, afordability isnt everything, its the only thing. by making my product(s) inexpensive I can meke it possible for those who need them the most to be able to get/make them. this will benefit their entire family makeing to possible to feed themselves. I can use local materials that can be gathered, bartered, or traded very easily for little to no cost. when one family has a better outlook by being able to feed themselves, others will see & ask how it was done, then they too will learn to feed theirselves, and on & on spreading farther & farther in a web of learning. 1 to 1million or even more each teaching another.
