Banana Power!

ackthpt writes "What do you do with rotten bananas, assuming you don't have 1337 5k1ll2 in baking banana bread? Especially a bit of a quandry if you grow bananas and 30% of your crop goes to waste? Bill Clarke, an engineering lecturer at the University of Queensland has devised a way to generate electric power, potentially enough for 500 homes, from the waste of Northern Queensland banana plantations. Nuts and bolts issues like if it's ultimately practical to haul the bananas, decompose them to methane and disposal of waste have yet to be worked out -- don't expect this to power your laptop just yet."

Re:So that's what you do with them

Err, well bannana bread fodder is not rotten, per se... just mushy, soft and oxidized to where they turn brown. Give them a few days and they will start stinking up the place, though.

Banana Bread, recipe courtesy of Emeril Lagasse

[(H)elix1]

Not hard at all...

1/2 cup solid vegetable shortening
1 cup sugar
2 eggs
3/4 cup mashed ripe bananas
1 teaspoon baking soda
1/2 teaspoon salt
1 1/4 cups flour
1/2 cup macadamia nuts
Pinch of cinnamon

Preheat the oven to 350 degrees.

Oil and flour a 9x5x3-inch loaf pan.

Using an electric mixer, cream the shortening and sugar. With the mixer running on medium speed, add the eggs one at a time. Add the bananas and mix well. Add the baking soda, salt, flour, nuts and cinnamon and mix thoroughly. The dough will be sticky.

Pour the dough into the prepared pan and bake about one hour or until the center is brown and set.

Scientists need some common sense

[MarkGriz]

Not trying to troll here. It's a clever use of an otherwise wasted resource. But common sense tells you this isn't commercially viable on such a small scale. Lets use some rough numbers:

500 homes * $100/month electicity * 12 months = $600,000/year income generated.

That wouldn't even cover the salaries of the employees running the plant, nevermind the cost of construction.

What might make more sense is to use the bananas along with other biowaste in a large scale plant.
Or how about just donate them to the zoo. Monkeys don't care about small/bruised bananas

Make sure that you know what ripe means.

[MarsDefenseMinister]

Ripe doesn't mean yellow. Ripe means black and squshy. If you make a banana bread with bananas that aren't ripe enough, you'll get a flavorless bread.

Let those things get some nice big black spots on them. That's the full banana flavor developing.

Take it from the experts - the fruit flies. If you give them a choice, they will always pick the squishy banana over the not-ripe-enough yellow ones. And you should too.
