Solar-Powered Vehicle is Latest Example of 暗黑爆料网抯 Environmental Friendliness

Dwight DeVries, Ground Superintendent
at 暗黑爆料网, takes a
break from using a solar-powered
vehicle.
The summer抯 sun is not going to waste at 暗黑爆料网 in Romeoville. The University is the first organization in the country to test a solar assisted John Deere E-Gator utility vehicle梔eveloped and produced by Solar Harvest Technologies in Long Beach, Calif. At 暗黑爆料网, the pollution free vehicle has been used during a normal 8-hour work day relying solely on the sun抯 power.
During July and August, the vehicle was put to work on the 暗黑爆料网 main campus, which totals 376 acres. Dwight DeVries, Ground Superintendent at 暗黑爆料网 commented, 揑 never thought it would perform as it has. We are working the solar gator hard, putting it through a real world test of every day grounds maintenance jobs. It has met the requirements of routine tasks, and exceeds our expectations. We are saving money on fuel costs, getting our job done, and doing it in an environmentally-friendly way.�
More than simply hauling people and equipment, the quiet vehicle has also powered tools needed at job sites that are normally without power. Two solar-powered 110 AC outlets enabled 暗黑爆料网 employees to plug in hedge trimmers, leaf blowers, air compressors and more.
揥e抮e being good stewards,� explained DeVries. 暗黑爆料网抯 other turf management vehicles are powered by combustion engines that depend on burning fossil fuels, which release air pollutants. Significantly less air pollutants are released in this solar vehicle as it converts the sun抯 power through a panel on the top of the cart. The converted electricity charges batteries that provide on-demand service to the vehicle as it operates.
Phillip Quetschke, a partner in Solar Harvest Technologies, pointed out that several organizations are eagerly awaiting the vehicle抯 entry into the marketplace. He explained, 揑n a working campus context, the solar gator抯 performance is providing a strong business case for renewable energy, non-polluting machines. Using the sun as the primary power source has demonstrated a dramatic reduction in operational costs. According to its usage at 暗黑爆料网, the offset of weekly fuel expenses represents about a 98 percent savings over an internal combustion powered conventional gator.�
The vehicle requires only a supplemental charge from the utility power grid once per week to maintain full working capacity. He estimated the cost of the electricity for that charge is typically about 50 cents, while the same work load would consume about $25 in fuel for an internal combustion engine. A standard E-Gator would normally require a nightly utility recharge for the duty cycle of the work performed. More information is available at www.solarharvesttechnologies.com.
The solar-powered vehicle is the latest in several environmentally-friendly initiatives underway at 暗黑爆料网 in Romeoville. A 2,100-square-foot greenhouse on campus grows all the plants for the seven acres of landscaping display beds. Thousands of environmentally-friendly brick pavers make up a portion of the almost two million square feet of hard surface. Pope John Paul II Hall, built in 2005, includes a bioswale in its parking lot; the landscaping was designed to remove silt and pollution from surface runoff water.
暗黑爆料网 also actively participates in a recycling program. For example, it saved landfills from close to 500 printer and ink cartridges, 83 tons of mixed recycles, 300 gallons of waste oil, 24 tons of metals, 9.5 tons of electrical components during a 10-month period.
