Dear Pannirselvam Thanks for your message, sorry for the late reply.

Which small press it that, Pan? Is it this one? The Sunflower Seed Huller and Oil Press http://journeytoforever.org/biofuel_library/oilpress.html Do you have any photographs of it being used? > We believe , there is no need of bioD , as we already can use oil >directly upto 25 porcent by blending with petro deisel as this is >very cheaper in rural area too , the blending of BIOD from caster , >we hope to get the better results . > > Brazil has 20 years of good research reports about castor oil use >as biofuel , which we have the acess .One main problem with castor >oil BioD is the viscosity that can be easily solved. That seems to be the main problem. Castor oil is 100 times more viscous than petro-diesel. Castor oil biodiesel is less viscous than the straight oil, but several references say it is still higher than the national standards specification limits. If there is an easy way to make it less viscous or to solve the problem that would be valuable to know. Do you have any further information on this? This is quite interesting on how castor oil works as a lubricant and why it's different to other oils: http://www.georgiacombat.com/CASTOR_OIL.htm CASTOR OIL > We are ready to shar the the Brasilian research effort as we >believe that we will be the number one in the world to come up with >this biofuel , not because of the will of the 8 biilions of liters >of alcohol we produce , because the country has the vast land >resources nearby by the Africa , and Europe where there is need >for the fuel . > > Yet big is not not beautifuel , That's a very good word!

You are surely right. Doesn't it also mean that the market in Europe might not be so important because of the "fuel miles" issue, the unsustainability of using fuel to transport fuel over long distances? > In this respect our biofuel list members are more aware , yet >we need to come together , give and take our hands to solve the >problems , mainly the from tropical south countries with the need to >duplicate the big scale BIOD busines mistake of the >developed countries as other need not blindly copy the Big one >HIGH TECH . Yes, in a way they are in a better position, they can "leapfrog" to sustainable energy without the obstacle of huge central industries and their influence on policy.
