I believe the verse for this Rolling Stones classic goes like this:
You can't always get what you want (X3)
But if you try sometimes you just might find
You just might find
You get what you need.
What has this to do with knowledge and the material progression of humanity? Well a lot is the answer. Reading the article in Popular Science magazine by Jeremy Hsu entitled, "Algae Used to Produce Green Plastics, Sans Petroleum." The first sentence reads, "Algae - derived plastics could cut more than half of the petroleum currently used in traditional production." Traditional of course meaning plastics from petroleum. It is a great vision, it is the greatness of a vision that leads people to do the extraordinary. Plastics derived from algae to save the environment, save the earth, save humanity, and get a decent reward for the effort is driven by q great vision. Cereplast, the firm that has undertaken the research hopes to be well rewarded for it's efforts, that is what they want.
However, many times the market does not agree with what we want, with what you want. It will of course, realistically speaking, take time if ever for algae based plastics to be competitive with petroleum based plastics, even though algae grows in abundance. It will take time meaning you can't always get what you want. However, surely there will be a market for algae based plastics, 100% renewable, Cereplast will get what it needs, if it has covered it's patent base. They want to dominate the market but they will get their niche, they hopefully will get what they need.
If you try, sometimes you get what you need should be remembered by all those who are have extraordinary vision. Increasing the knowledge base is done by a very few extraordinary percentage of the earths human population, hence envy and jealousy that they face. These extraordinary visionaries who strive must remember that one does not always get what they want, but usually they will get what they need through all the drag, therefore do not conform for the sake of conforming, keep researching, the break through will come and you will get what you need.
