The only application for such fuels is when they are recycled from existing oils, or made from toxic crops like sugar. The reason that ethanol is not mainly being made from sugar is because it will increase the cost of sugar worldwide and affect certain companies that routinely use sugar unnecessarily in a wide range of products. It is sugar (cane and beet) that require extensive use of petro-chemical fertilisers and pesticides to produce cheap food-grade quantities. Used for ethanol production there would be a very different story!
The reason that grain surpluses and maize, staple foods of poor people, are being used is because the elite wants a cull of the majority of the human population and know that we are heading for a global cooling and ice age where millions will starve very quickly without the essential surpluses.
As the elite prepares for the coming cold and crop failures by creating more shelters and storage facilities for themselves, they continue with the lie about CO2 causing climate changes as a distraction from what is really going on.
As is well known by all concerned, CO2 forms less than 10% of the atmosphere's gases and less than half is created by humans. So, to go on and on repeating the same lies about CO2 causing 'global warming' exposes those who have the secret agendas and the brainwashed followers who have been kept in fear. Fear in turn paralyzes the population at a time when those who wish to survive will be best preparing by developing a range of decentralised and sustainable systems and communities.
As the wise planetary elders have said: " The Children of the Earth will survive"
