Everyone seen cows more leisurely walk in the animal farm scene, scattershot, walk while eating grass. If came to Northern Ireland, in Mr William Taylor's ranch, you can see cows in a power car step, for his farm power generation.

Animal power generators (pictured) is raised at the top of the box, attracts the cows on the belt of generators. And power car is designed so that: if the cows standing above the belt, the belt will bring cows to decline slowly, causing cows away from the feed box, thus induce cows constantly move forward. Cow step belt rotation, drive the gearbox, and drive the power generator parts. A cow "walk" in a row, a long "travel", typically can power up to 2 kw, enough to drive four milking machine.

Animal power generators to cattle more exercise, and also offer green energy. Someone calculated that if the 1.3 billion head of cattle on the earth "to work eight hours a day, can provide 6% of the world's energy needs. Of course, this is just a "fun math", after all, no one can prepare so many animal power generators to shave billions of cows.

Mr Taylor ever invented many things during the process of cattle, such as that of manure mixer, prevent the cow to the veterinary corral. Animal power generation is the first time he entered the energy sector. When he looked at the cows all day walking around, just want to have a day to the movement into energy. As for cost, his data is: a small ranch, 50 cow, form a complete set of animal power generator price is about $100000, estimates that can earn back to 3 years.

Some researchers think that can produce more milk cows to take more exercise. Mr Taylor also plan this autumn, from the perspective of health benefits evaluation system of their own. He was convinced that another benefit is, let cows to help generate electricity, will reduce their emissions of methane. He joked: "if nothing trifle, also many fart." If really can reduce the methane emissions of cattle, it will be beneficial to the environment. Some experts believe that the greenhouse gas methane, as many as 20% of all the world is from cattle and sheep to burp and fart emissions.
