We used to bake potatoes in piles of grass from when my dad mowed the lawn. wrap your potato in tinfoil twice and bury it at the bottom of a large grass pile in the morning and come back at the end of the day. the grass gets so hot as it starts to breakdown. this is I think due to fermentation inside the grass mound and the insulation of the outer layers.

It might have been a day or so after the grass had been cut rather than that day.

I don't know how safe or clean it was, or how long it actually took to cook, or whether or not you _should_ do this, but we did, and it worked at least a few times

Green hay stored in a barn after harvest, heats up, and releases gasses.

More than one barn has exploded over the years...

(Most let it dry before storing it in the barn...)

Even if it doesn't explode, it molds if you pile it up before it's good and dry. That's the whole fun of baling hay. You've got to try to predict a two or three day window (or more depending on temp and humidity) where you don't think it's going to rain. Cut one day, turn the next day or so, maybe turn again, then bale and stack when it's as dry as possible or in a panicked rush when the weather begins to roll in. At that point any bales with greasy spots usually get thrown to the side to get fed out first before they mold.

I'm curious what circumstances besides desperation not to lose your cutting would lead you to put it up with high enough moisture content that there's risk of explosion.

Only read the headlines but was this the cause of the recent cow-farm explosion?
