    Summary of the research paper:

    A 3 page paper offering an alternative design for a cutting blade for an electric lawn mower. There is particular attention toward the development of better and more desirable cordless electric lawnmowers and other lawn maintenance equipment, but there is an ongoing struggle to balance performance issues and power consumption. The paper suggests using titanium as the material from which the blade is manufactured, and extending the cutting edge the entire length of the blade for better performance with decreased use of power. Bibliography lists 4 sources.

    Unformatted Sample Text from the Research Paper:
    are striving to provide the optimum balance of power and performance in electric lawn maintenance equipment. There is particular attention toward the development of better and more desirable cordless  electric lawnmowers and other lawn maintenance equipment, but there is an ongoing struggle to balance performance issues and power consumption. "If you get more power in the machine, then  theres less run-time. If you try to design for longer run-time, then you end up with less power. Its a difficult balancing act to find the best combination of size,  power, and run-time" (LePree, 2003; p. 28). The purpose here is to suggest an alternative blade design for an electric lawn mower that will increase power efficiency by a  significant margin while maximizing the life of the blade through the use of alternative materials. Suggested Design Changes There are some paradigm-changing approaches  to grass cutting that have been conceptualized by a few manufacturers, such as Briggs and Strattons PowerLink system, which generates 1.5 kW of a.c. current by using the engine on  a riding lawn mower (A generator that cuts grass, 2002). One company, Europes Wolf-Garten, "has developed a lawnmower for consumer use that slices grass by laser, cutting it so  finely that the pieces can remain on the ground as fertilizer" (A cut above the rest, 2001; p. 78). The company "claims the two-seat open vehicle is powerful enough  to be registered for road use" (A cut above the rest, 2001; p. 78), and at the price that the company foresees for the product, it would indeed need to  be multifunctional for most potential customers. At $30,000, Wolf-Gartens intentions in 2001 was to produce the laser lawn mower only if there was enough interest from dealers.
