The process is called development. In a capitalistic system it is critical that "early adopters" engage with manufacturers so that the demands of the market can mold the technology of the future.
If no one ever bought a flash light battery, where would battery production be today?
If no one ever tried the concept of commercial airliners what would have happened to the industry?
I made no claims of green, I do love innovation and entrepreneurs, and I think that supporting of concepts that have possibilities is one of the responsibilities of those who understand the research and development process.
Sheesh!
