Replying to a message of TOM WALKER to ROY WITT:

 BA>>>>> Heating oil is up $.40 in the past week or so. 
It's now about
 BA>>>>> $3.35/gallon. Dunno what I'm going to do next winter.

 RW>>>> Start collecting used deep fry oil from the fast food
 RW>>>> joints...there's a method to clean and thin it so it should work.

 TW>>> For a Diesel Car that may work but it is Hardly practical
 TW>>> concidering the Usage rate for House Heating.

 RW>> If that's true and I doubt that it is, then put the diesel engine in
 RW>> the basement and the coolant radiator upstairs...run a 12vdc fan off
 RW>> the alternator on the radiator.

 TW> How many Gallons per month typicaly does one need to heat their House
 TW> i nthe Winter?

In a cold month the oil furnace here will suck down about 200 gallons.  A bit less
than 7 gallons/day - at $3.40/gallon .

 TW> DO you think you can get that much Used Vegetable oil
 TW> per month from a Fast Food resturant?

7 gallons/day is probably doable if one has 2 or 3 restaurants as sources. 
Used motor
oil is probably a better source, IMO - there are already furnaces that
handle that.  But
if they haven't yet those folks are going to realize that they can *sell*
the used oil from
the fryers.  There are several people that run diesel autos/trucks on used
vegetable oil
they've collected and filtered.

 TW> Then think about it. IT IS A NOT PRACTICAL solution for home heating
 TW> on any scale at all.

Especially if several dozen/hundred people are all trying to do it.  The
supply of used
vegetable oil is finite, especially in small towns.
