I bought 3 - 55 gal plastic barrels for $12 a piece. They had soy sauce and vinegar in them.
I washed them out and after they dry I should be able to get a delivery of biodiesel at $5.09/gal from Simply Green in Stratham NH. It ain't cheap but I feel better if I am not using petroleum. Maybe I will start brewing my own. This site Utah Biodiesel Supply seems pretty good. I found the tank pump I needed from them for $25.

I also was looking at hot water heaters to replace my oil burner hot water. $269 at Home Depot. Insulate it well and it might make sense. I currently use about 220 gal of oil to heat my hot water for a year.
Solar hot water using vacuum collector tubes. About $5000. Ugh!
They recommend the vacuum tube type for up north.

Cordwood from my usual supplier is $270 a cord delivered and he can't deliver for 1.5 months. Gee! That would make it august before I could get the wood. It doesn't dry well when I get it in august. I will probably cut more wood from my own property and try other suppliers I know of.

I will get a price on pellets monday because I think I will prebuy pellets this year. I can store 2 tons in my garage.
