Dunkin' Donuts built a tiny home that's powered by coffee - and it cost just $10 a night to stay there
To come up with a coffee-powered energy system, Dunkin' partnered with Blue Marble Biomaterials, a company that takes wasted resources and converts them to fuel.

Blue Marble took the oil from 65,000 pounds of coffee grounds and converted it into biofuel.

A single gallon of fuel requires around 170 pounds of spent coffee grounds.
In addition to conserving energy, the process prevents coffee grounds from winding up in landfills.

The decomposition of coffee grounds releases methane — a greenhouse gas that's up to 35 times as potent as carbon dioxide.
But there's a caveat: The biofuel blend consists of only 80% coffee oil.

In order to be converted into fuel, the coffee is mixed with 20% alcohol.
The design was executed by New Frontier Tiny Homes, who wanted the exterior to mimic the color of coffee.
