Experiment Could Keep Cows Cool, Reduce Energy Costs

Research being conducted on a California farm could help cows stay cooler during the summer while reducing the energy costs needed to power overhead fans used to do the same job. The technology, developed by Arizona-based AgriAire Inc., pumps water from a farm well into a heat exchanger beneath a cow’s stall, which creates an updraft of cool air. The new system could save a typical dairy farmer more than $7,000 a year in utility costs — the amount it generally takes to power nearly 55 electrical fans. (McClatchy Newspapers) Read more.
