Scientists are constantly warning us that oil supplies are running out, therefore we should look for alternative sources of energy. Electric vehicles are all good and well, but they require a completely new infrastructure on a global basis, something that’s not likely to happen very soon. Moreover, they are expensive and have many limitations – but that is a different story.
So far, the prime replacement of fossil fuel is biodiesel oil, which is made of soybeans. The problem is soybeans are also used for human and animal consumption.
