Cars that run on grease and hay insulation

 Late to the Green Party on our block.

Our soon to be neighbor across the street has this old Mercedes (see below) that she has converted to run on grease. She picks up the grease from the Asian restaurants nearby, strains it in her backyard and fills her car up.

On a similar note she has chickens in her backyard. No these aren’t rubber chickens she uses for jokes, these are the real feathery kind. Apparently she uses them for eggs, or I suppose for organic gardening as well (chicken poop = nitrogen for plants).  Anyhow, I’m not ready to take my sustainable commitment to the next level with livestock in my back yard, so maybe i’ll never been the greenest guy on the block.
Speaking of chickens and livestock, I wanted to take a moment to highlight the original insulation from our 1920’s bungalow. No, it’s not the pink panther, though I do wonder how Owens Corning got that character for their mascot, and do they still pay royalties?   What we have/had as our insulation is hay; plain old straw hay.     
It was stuffed in the ceiling in bags and bags. It also appeared that there was some kind of chemical coating (possibly fire retardant)  which was applied to the bags. Or it just could’ve been a layer of harsh dust.  As you can imagine, after 90yrs this stuff is pretty dry, and I was certainly a bit nervous as my Marlboro smoking demolition guys took their smoke breaks. They got specific instructions to not smoke near the straw.   And now that the last straw hay bag is out, I can sleep soundly knowing my place won’t as easily go up in smoke. And why wallet will sleep soundly when my energy bills are reduced by improved insulation.
