America. Worldwide annually 236,000 metric tons of oil & oil products from average pleasure boats is leaked into the water, equivalent to more than 7 times the amount spilled by the Exxon Valdez in Alaska in 1989. Aware of agricultural pollution in Iowa's lakes and rivers, however, oil and gas leaks from boats also require to develop eco-friendly boat technologies Developed for a ZERO EMISSION eco-friendly boat for Iowa lakes & rivers! pecen@uni.edu 1

2008 Project # 2 Eco-Friendly Lawn Mower UNIMow John Gregorich & R. Pecen EET 2006-07 Senior Design project Operating a gas mower for 1 hr produces the same pollution as driving a car 1300 miles. Each weekend, about 54 M Americans mow their lawns, using 800 M gallons of gas per year. An EPA study found that ~ 9 % of some types of air pollutants nationwide come from lawn & garden equipment small engines. In 1 hr mowing, 26 different pollutants were found in the exhaust of the mowers. Does solar power help to mow? Engine is composed of a motor, battery and PV Panels Circuit Design 70A UNIMow Test Drive: Saturday, April 21, Earth Day (April 22) Celebration in Waterworks Park, Des Moines.

However, if the sample rate is high (10Hz or above), sensor nodes could not go to sleep and thus the lifetime is very limited. Small scale energy harvesting from the ambient environment is very attractive to implement a selfsustainable system Jin Zhu, U. of Northern Iowa pecen@uni.edu 5
