A crash course in changing the world.
Energy-generating treadmills for humans? William Taylor,
a farmer in Northern Ireland, has decided to put idle cows
on treadmills to produce power for his farm,
according to Popular Science.
The inclined belt causes cows to slide off unless they continue to move forward.
The forward-walking motion causes the belt to turn, spinning a gearbox that
drives a generator. A feed box sits in front of the treadmill to keep the cows
on their toes. It's not as crazy as it sounds. Cows already spend up to 8 hours
a day milling around while grazing. Taylor just sticks the cows on a treadmill
for part of the time. The farmer's prototype treadmill can generate two kilowatts,
or enough energy to power four milking machines.
Cows that exercise are also thought to produce more milk.
