UF's Southwest Recreation Center is turning your sweat into savings.
The center has six elliptical machines hooked up to a system that converts energy from a workout into electricity that is pumped back into the power grid, saving money on utilities.
Four more machines will be installed within the next week or so, said Hudson Worthington Harr, founder of ReRev and inventor of the technology, called ReCardio.
It cost UF about $1,500 to install the first six machines, said David Bowles, UF director of RecSports.
Harr, who graduated from UF in 2007 with a finance degree, said he will install the new machines free of charge because he likes to give back to his alma mater.
He said the six machines have produced about 300 kilowatt hours of electricity since the beginning of the semester. The average U.S. residence used about 920 kilowatt hours a month in 2006, according to the U.S. Department of Energy.
