Thus the new chains and padlocks on those "waste" grease drums.

See, every month, I pay an extra 25% surcharge on natural gas
because I *always* exceed the first 'baseline' quantity tier.
Once, I actually got to the third tier! That was an awe-inspiring bill.

I don't really need gigawatts. I need 15 therms a month to keep me
on the first tier. A one gallon slurry jug should produce upwards
of 18 therms a month for three months before recharging.

Not a chance. If your digester uses free fuel and produces 7 x more
methane than my digester (that I have to pay to fuel), I'm gonna have
a rough time convincing you to swap with me, yes?

I don't know anything about that.
I get uneasy when I see a computer running a slot machine or
a gas meter though. :)

None that you or DimBulb could possibly answer, no.

That is only the price when you want it. When you have a
lot of cows, you have it but don't want it. When the supply
is large and the demand is negative, the price tends to be
low.

Unless the source was willing to deliver with a
sizable cash payment, the stuff is much better used
as a soil amendment, IMHO.

"Residual Fats" are a very different story, with
24 x higher methane production than manure.

throws away!
