I dunno,but I still think salvaging heating oil from houses where the owner
is convertiong to natural gas is a source of overlooked bio-diesel
(technically not bio diesel).Diesel fuel = heating oil- road taxes.  I dont
have a diesel(still wish I did),but if I did,I would contact several HVAC
companys and check if they need the old leftover oil removed from the tank
(hazardest material).Not too many gallons /tank, but if I could pump a few
per week,I would be set.Get to do it regualrly for these companys and do it
right,and have them call me whenever they have a conversion to do from a
heating oil customer.I could even stock it up in an old 275 gallon tank in
the basement.Many people are doing this conversion year round.Even when
they are replacing or adding central air.I heard last night that naural gas
prices have fallen by 50 perecnt or more recently.In the DC area,
electricity prices are set to go up 70-80 percent next
month ,overnite.Deregulation they say.Nautral gas (or fire wood) is the way
to go around here.
