1.60 a gallon methanol
~1 per gallon glycerin
covering cost per gallon or “cheap” fuel glycerin/ol mixed with methanol to achieve burning of glycerin/ol produccing free glycerin/ol from used fryer oil is possible but become upwards of 50/50 to burn successfully. or, expect more glycerin than the burnable materal more often than not.
average cost of a 50kw generator alone is possible in the 2.5k range and thus an atomizing burner and purifying equipment is about the same thus a dollar a gallon in transportation and thus ultimately the first year is a wash to run and the second through service break even is another 3 years or to run or thus with 5 more years possible with proper maintainance and luck it is possible to make about 50% off grid prices if one can do all this weighted first supply and mainatainance plus equipment to burn basic recycled materieal … for “free” which in denver/xcel energy is 130 a month electricity/6people 2 a/c 2 big tvs electric reange lights or and 3 grow lights in cycles … or 65 a month again off with 1/4th your paying out cost paid back in for fair market value back. or ten years effort to gain 50% ultimately off with daily maintainance and heavier weekly chores and monthly high loss preventaives and yearly overhaul loss of half week. or,
what a hell of a lot of work slogging about for “free”
