Can the Power of Oxen Generate Electricity as an Energy Farming Supplement

"The sun doesn't shine all day, it doesn't shine every day, and, likewise, the wind doesn't blow all the time." - Bill Gates

Hypothesis: If ordinary cattle are trained from birth to perform one simple task involving the pulling a rope that is attached to them as they continuously walk around the circumference of a loop -- their combined strength and participation can be harvested into mechanical energy whose energy spins turbines that produce electricity.

Can such an endeavor serve as a supplement during time periods when wind isn't available?

My Invention: consists of a mechanism that attaches the yokes of multiple teams of Oxen onto a single rolling chain that forces them to generate rotational energy as they pull the chain continuously around the circumference of a loop. The resulting mechanical energy will then be used to produce electricity via Turbine that spin as a result by attaching themselves alongside the inner side of the loop. Read more on my blog. Thanks!
