  • Vegetable oil comes from a renewable source and, contributes to improve the environment, since it prevents global warming, because the C0 2 (Carbon dioxide) that is generated in its combustion, will then be absorbed by the plantations that are used to produce vegetable oil, since as we know, plants absorb C0 2 to be able to carry out photosynthesis and thus develop. Therefore we reach a closed cycle, where the C0 2 generated by the combustion of vegetable oil is reduced to practically zero when absorbed by the plantations from which we obtain the vegetable oil, also due to these plantations it contributes to develop agriculture .
  • Another important advantage of vegetable oil and water as fuels is that no new infrastructure would be needed to commercialize them, since the same gas stations and machines could be used to dispense the existing fuel in them.

  • the idea would be, not to use the fresh water we consume in our homes, if not, use desalinated water, collecting seas and oceans.
  • the cost of the cubic meter of desalinated water is currently approximately 0.60 Euros, and the cubic meter could cost one Euro, due to the successive increase in the price of oil.
  • the thickness of the surface layer or film of water that would be consumed per year over the entire surface of the globe would be 0.0001 1 millimeters, in 1000 years a thickness of water layer of 0.1 1 millimeters would be consumed, approximately one tenth of a millimeter in a thousand years, so, as we can see, water along with vegetable oil can be a sustainable and renewable Biofuel, and the possible consumption of water, it would not affect our planet in the least, since the thickness of the water layer would be infinitely small, which could be consumed throughout the globe, over a long period of time.
