Happy new year
Technical project with more energy efficiency alone without economical
and ecological viability.Due to val energy high loss in electric energy
distribution,smaller units it is possible to consider generating sets using
combustion
engines especially optimised for running on bio-oil or ethanol/methanol/DME
, an felxible mutifuel engine such as one working flex fuel in Brazil
that you buy on the future automotive fuel market.
We are initiating d to make
such studies and wish you join with us for this collaborative study
yours truley
