Forget the gas station — your next car could have you fueling up at the farm.

Toyota’s really moooo-ving on a concept car fueled by cow droppings.

The company has debuted a complete redesign of its Mirai concept vehicle which would run on hydrogen fuel cells converted from bovine poop.

The feces could produce enough hydrogen to run the reimagined Mirai for a year, Toyota chief technology officer Shigeki Terashi told an audience at the 2019 Tokyo Auto Show, according to Car and Driver.

The zero-emission concept car uses a “fuel stack” to transform liquefied hydrogen into electricity with water as the only byproduct.

The new Mirai goes on sale in 2021.

It’s not the first time Toyota has experimented with the potential of animal excrement.

In 2017, the company announced plans to build a California power plant to capture methane gas from dairy cattle manure to generate water, electricity and hydrogen. The power plant is partnered with Shell.
