Sunlawn EM-2 Electric Mower
Cutting grass is a common chore, yet few folks who claim to live "green" realize their gas mower puts out more pollution in an hour than several cars combined. The Sunlawn EM-2 Electric Mower ($380) is powered by two easily replaceable 12-volt SLA batteries that let the mower run for more than a full hour on a single charge. Its seven-blade cutting system keeps your lawn looking great, and the relatively silent operation lets you mow at any hour without disturbing the neighbors.
